WARNINGS (for using R290/R32 refrigerant only)
  • Transport of equipment containing flammable refrigerants See transport regulations
  • Marking of equipment using signs See local regulations
  • Disposal of equipment using flammable refrigerants See national regulations.
  • Storage of equipment/appliances The storage of equipment should be in accordance with the manufacturer’s instructions.
  • Storage of packed (unsold) equipment Storage package protection should be constructed such that mechanical damage to the equipment inside the package will not cause a leak of the refrigerant charge. The maximum number of pieces of equipment permitted to be stored together will be determined by local regulations.
  • Information on servicing
  • Checks to the area Prior to beginning work on systems containing flammable refrigerants, safety checks are necessary to ensure that the risk of ignition is minimized. For repair to the refrigerating system, the following precautions shall be complied with prior to conducting work on the system.
  • Work procedure Work shall be undertaken under a controlled procedure so as to minimize the risk of a flammable gas or vapor being present while the work is being performed.
  • General work area All maintenance staff and others working in the local area shall be instructed on the nature of work being carried out. Work in confined spaces shall be avoided. The area around the workspace shall be sectioned off. Ensure that the conditions within the area have been made safe by control of flammable material.
  • Checking for presence of refrigerant The area shall be checked with an appropriate refrigerant detector prior to and during work, to ensure the technician is aware of potentially flammable atmospheres. Ensure that the leak detection equipment being used is suitable for use with flammable refrigerants, i.e. non-sparking, adequately sealed, or intrinsically safe.
  • Presence of fire extinguisher If any hot work is to be conducted on the refrigeration equipment or any associated parts, appropriate fire extinguishing equipment shall be available to hand. Have a dry powder or CO2 fire extinguisher adjacent to the charging area.
  • No ignition sources No person carrying out work in relation to a refrigeration system which involves exposing any pipe work that contains or has contained flammable refrigerant shall use any sources of ignition in such a manner that it may lead to the risk of fire or explosion. All possible ignition sources, including cigarette smoking, should be kept sufficiently far away from the site of installation, repairing, removing, and disposal, during which flammable refrigerant can possibly be released to the surrounding space. Prior to work taking place, the area around the equipment is to be surveyed to make sure that there are no flammable hazards or ignition risks. No Smoking signs shall be displayed.
  • Ventilated area Ensure that the area is in the open or that it is adequately ventilated before breaking into the system or conducting  any hot work. A degree of ventilation shall continue during the period that the work is carried out. The ventilation should safely disperse any released refrigerant and preferably expel it externally into the atmosphere.
  • Checks to the refrigeration equipment Where electrical components are being changed, they shall be fit for the purpose and to the correct specification. At all times the manufacturer’s maintenance and service guidelines shall be followed. If in doubt consult the manufacturer’s technical department for assistance. The following checks shall be applied to installations using flammable refrigerants:
  • The charge size is in accordance with the room size within which the refrigerant containing parts are installed;
  • The ventilation machinery and outlets are operating adequately and are not obstructed; If an indirect refrigerating circuit is being used, the secondary circuit shall be checked for the presence of refrigerant;
  • Marking to the equipment continues to be visible and legible. Markings and signs that are illegible shall be corrected;
  • Refrigeration pipe or components are installed in a position where they are unlikely to be exposed to any substance which may corrode refrigerant containing components, unless the components are constructed of materials which are inherently resistant to being corroded or are suitably protected against being so corroded.
  • Checks to electrical devices Repair and maintenance to electrical components shall include initial safety checks and component inspection procedures. If a fault exists that could compromise safety, then no electrical supply shall be connected to the circuit until it is satisfactorily dealt with. If the fault cannot be corrected immediately but it is necessary to continue operation, an adequate temporary solution shall be used. This shall be reported to the owner of the equipment so all parties are advised. Initial safety checks shall include:
  • That capacitors are discharged: this shall be done in a safe manner to avoid possibility of sparking;
  • That no live electrical components and wiring are exposed while charging, recovering or purging the system;
  • That there is continuity of earth bonding.
  • Repairs to sealed components
  • During repairs to sealed components, all electrical supplies shall be disconnected from the equipment being worked upon prior to any removal of sealed covers, etc. If it is absolutely necessary to have an electrical supply to equipment during servicing, then a permanently operating form of leak detection shall be located at the most critical point to warn of a potentially hazardous situation.
  • Particular attention shall be paid to the following to ensure that by working on electrical components, the casing is not altered in such a way that the level of protection is affected.
  • This shall include damage to cables, excessive number of connections, terminals not made to original specification, damage to seals, incorrect fitting of glands, etc.
  • Ensure that apparatus is mounted securely.
  • Ensure that seals or sealing materials have not degraded such that they no longer serve the purpose of preventing the ingress of flammable atmospheres. Replacement parts shall be in accordance with the manufacturer’s specifications.
  • NOTE: The use of silicon sealant may inhibit the effectiveness of some types of leak detection equipment. Intrinsically safe components do not have to be isolated prior to working on them.
  • Repair to intrinsically safe components Do not apply any permanent inductive or capacitance loads to the circuit without ensuring that this will not exceed the permissible voltage and current permitted for the equipment in use. Intrinsically safe components are the only types that can be worked on while live in the presence of a flammable atmosphere. The test apparatus shall be at the correct rating. Replace components only with parts specified by the manufacturer. Other parts may result in the ignition of refrigerant in the atmosphere from a leak.
  • Cabling Check that cabling will not be subject to wear, corrosion, excessive pressure, vibration, sharp edges, or any other adverse environmental effects. The check shall also take into account the effects of aging or continual vibration from sources such as compressors or fans.
  • Detection of flammable refrigerants
    Under no circumstances shall potential sources of ignition be used in the searching for or detection of refrigerant leaks.
  • halide torch (or any other detector using a naked flame) shall not be used.
  • Leak detection methods The following leak detection methods are deemed acceptable for systems containing flammable refrigerants. Electronic leak detectors shall be used to detect flammable refrigerants, but the sensitivity may not be adequate, or may need re calibration. (Detection equipment shall be calibrated in a refrigerant-free area.) Ensure that the detector is not a potential source of ignition and is suitable for the refrigerant used. Leak detection equipment shall be set at apercentage of the LFL of the refrigerant and shall be calibrated to the refrigerant employed and the appropriate percentage of gas (25% maximum) is confirmed. Leak detection fluids are suitable for use with most refrigerants but the use of detergents containing chlorine shall be avoided as the chlorine may react with the refrigerant and corrode the copper pipe-work. If a leak is suspected, all naked flames shall be removed/ extinguished. If a leakage of refrigerant is found which requires brazing, all of the refrigerant shall be recovered from the system, or isolated (by means of shut off valves) in a part of the system remote from the leak. Oxygen free nitrogen (OFN) shall then be purged through the system both before and during the brazing process.
  • Removal and evacuation When breaking into the refrigerant circuit to make repairs or for any other purpose, conventional procedures shall be used. However, it is important that best practice is followed since flammability is a consideration. Opening of the refrigeration systems shall not be done by brazing. The following procedure shall be adhered to:
  • Remove refrigerant;
  • Purge the circuit with inert gas;
  • Evacuate;
  • Purge again with inert gas;
  • Open the circuit by cutting or brazing. The refrigerant charge shall be recovered into the correct recovery cylinders. The system shall be flushed with OFN to render the unit safe. This process may need to be repeated several times. Compressed air or oxygen shall not be used for this task. Flushing shall be achieved by breaking the vacuum in the system with OFN and continuing to fill until the working pressure is achieved, then venting to atmosphere, and finally pulling down to a vacuum. This process shall be repeated until no refrigerant is within the system. When the final OFN charge is used, the system shall be vented down to atmospheric pressure to enable work to take place. This operation is absolutely vital if brazing operations on the pipe-work are to take place. Ensure that the outlet for the vacuum pump is not close to any ignition sources and there is ventilation available.
  • Charging procedures In addition to conventional charging procedures, the following requirements shall be followed.
  • Ensure that contamination of different refrigerants does not occur when using charging equipment.
  • Hoses or lines shall be as short as possible to minimize the amount of refrigerant contained in them.
  • Cylinders shall be kept upright.
  • Ensure that the refrigeration system is earthed prior to charging the system with refrigerant.
  • Label the system when charging is complete (if not already).
  • Extreme care shall be taken not to overfill the refrigeration system.
  • Prior to recharging the system it shall be pressure tested with OFN. The system shall be leak tested on completion of charging but prior to commissioning. A follow up leak test shall be carried out prior to leaving the site.
  • Decommissioning Before carrying out this procedure, it is essential that the technician is completely familiar with the equipment and all its detail. It is recommended good practice that all refrigerants are recovered safely. Prior to the task being carried out, an oil and refrigerant sample shall be taken in case analysis is required prior to re-use of reclaimed refrigerant. It is essential that electrical power is available before the task is commenced.
  • Become familiar with the equipment and its operation.
  • Isolate system electrically.
  • Before attempting the procedure ensure that:
  • Mechanical handling equipment is available, if required, for handling refrigerant cylinders;
  • All personal protective equipment is available and being used correctly;
  • The recovery process is supervised at all times by a competent person;
  • Recovery equipment and cylinders conform to the appropriate standards.
  • Pump down refrigerant system, if possible.
  • If a vacuum is not possible, make a manifold so that refrigerant can be removed from various parts of the system.
  • Make sure that cylinder is situated on the scales before recovery takes place.
  • Start the recovery machine and operate in accordance with manufacturer’s instructions.
  • Do not overfill cylinders. (No more than 80% volume liquid charge).
  • Do not exceed the maximum working pressure of the cylinder, even temporarily.
  • When the cylinders have been filled correctly and the process completed, make sure that the cylinders and the equipment are removed from site promptly and all isolation valves on the equipment are closed off.
  • Recovered refrigerant shall not be charged into another refrigeration system unless it has been cleaned and checked.
  • Labeling Equipment shall be labeled stating that it has been de-commissioned and emptied of refrigerant. The label shall be dated and signed. Ensure that there are labels on the equipment stating the equipment contains flammable refrigerant.
  • Recovery When removing refrigerant from a system, either for servicing or decommissioning, it is recommended good practice that all refrigerants are removed safely. When transferring refrigerant into cylinders, ensure that only appropriate refrigerant recovery cylinders are employed. Ensure that the correct number of cylinders for holding the total system charge is available. All cylinders to be used are designated for the recovered refrigerant and labeled for that refrigerant (i.e. special cylinders for the recovery of refrigerant). Cylinders shall be complete with pressure relief valve and associated shut-off valves in good working order. Empty recovery cylinders are evacuated and, if possible, cooled before recovery occurs. The recovery equipment shall be in good working order with a set of instructions concerning the equipment that is at hand and shall be suitable for the recovery of flammable refrigerants. In addition, a set of calibrated weighing scales shall be available and in good working order. Hoses shall be complete with leak-free disconnect couplings and in good condition. Before using the recovery machine, check that it is in satisfactory working order, has been properly maintained and that any associated electrical components are sealed to prevent ignition in the event of a refrigerant release. Consult manufacturer if in doubt. The recovered refrigerant shall be returned to the refrigerant supplier in the correct recovery cylinder, and the relevant Waste Transfer Note arranged. Do not mix refrigerants in recovery units and especially not in cylinders. If compressors or compressor oils are to be removed, ensure that they have been evacuated to an acceptable level to make certain that flammable refrigerant does not remain within the lubricant. The evacuation process shall be carried out prior to returning the compressor to the suppliers. Only electric heating to the compressor body shall be employed to accelerate this process. When oil is drained from a system, it shall be carried out safely.

Before you mount your air conditioner


Understanding the window requirements

Your air conditioner is designed to install in standard double hung windows with opening widths of 22-36 in. (55.9-91.4 cm) and a window height of 13.5 in. (34.3 cm). The lower sash must open sufficiently to allow a clear vertical opening of 13.7 in. (34.9 cm). Side louvers and the rear of the AC must have clear air space to allow enough airflow through the condenser for heat removal. The rear of the unit must be outdoors, not inside a building or garage.


Vinyl-clad windows


Dealing with storm windows

If a storm window blocks your air conditioner, remove it before installing your air conditioner. If the storm window cannot be removed:

  • Make sure that the storm window’s drain holes or slots are not caulked or painted shut. Accumulated rain water or condensation must be able to drain out.
  • Attach a piece of wood across the entire window sill with nails or screws to correctly angle your air conditioner. Your air conditioner should be tilted back about 3-4° downward toward the outside. After proper installation, condensate should not drain from the overflow drain hole during normal use. If it does, adjust the angle of your air conditioner.
  • You must secure the support bracket to the added wood piece using the provided 1” type A screws. Refer to Step 2: Installing the support bracket on page 18.


Installing your air conditioner

Step 1: Preparing the support bracket
  • Remove your air conditioner, support bracket, and hardware from the box and place on a flat surface.
  • Remove the packing material.
  • Find the center of your window and lightly mark it with a pencil.
  • Press the left spring push pin and adjust the left extension arm out, then do the same for the right extension arm.


  • Measure the width of the inner windowsill. Making sure that the center of the support bracket lines up with the center of the window, then adjust the extension arms to the width you just measured. The support bracket will be offset to the left when centered.
  • Cut bracket sealing foam strips to length and apply to the bottom of the bracket.



Step 2: Installing the support bracket

CAUTION: Maintain control of the bracket until the installation is complete.

  • Open the window where your air conditioner is being installed.
  • Place the main support bracket into the window opening, making sure that the horizontal bracket and extension arms are located on the indoor side of the window.


  • Lower the bracket until it rests on the windowsill.


  • For wooden windows with a flat sill, secure the bracket to the windowsill by drilling 1/8 in. pilot holes and securing the bracket to the window with the 1/2” and 1” type A screws.

Note: If the gap between the bracket and the window sill exceeds 3/16 in. (5 mm), the bracket may be deformed while securing the 1″ type A screws, you can add a block to reduce the gap if possible.



  • For vinyl windows with a flat sill, secure the bracket to the windowsill by drilling 1/8 in. pilot holes and securing the
    bracket to the window with the 1/2” type A screws.


  • Move the angled support arms toward the exterior wall until the feet touch the wall. Place a level on the bracket and adjust the support arms so that it is level or tilted 1/4 bubble downward and towards the outside.


  • Insert the main support pin through the holes in the main support and angled support arm.


  • Using the numbers on the main support, repeat the adjustment for the other angled support arm matching the hole number from the first support arm.
  • Check the level again and make sure that the bracket is secure. If further adjustment is required, use alternate holes where the main supports attach to the horizontal bracket.


  • After making any final adjustments, insert the two cotter pins into the main support pin on both support brackets.


  • If necessary, cover the holes on the front of the bracket with bracket sealing foam.


Step 3: Installing your air conditioner on the support bracket

CAUTION: Do not leave your air conditioner unattended during installation.

  • Measure the width of your window track (the vertical track your window slides up and down in). If it measures 1/2“ or less, flip the anti-tip bracket so that the small end faces out, then continue with your air conditioner installation.


  • Set your air conditioner on top of the support bracket, making sure that the grooves on the bottom of your air conditioner align with the main supports. Using a level, check for proper tilt towards the outside.


  • Pull the window down into the slot on top of your air conditioner to help align it correctly. Keep the window partially inserted into the slot to help support your air conditioner during installation.


  • Fold down both side arm hinges.


  • Using 1/4 in. and 1/2 in. type B screws, install the open window brackets with an “L” shaped screwdriver, if needed.

WARNING: Failure to install the open window brackets could cause injury or property damage.


Step 4: Installing the sealing foam and anti-tip brackets

CAUTION: Do not leave your air conditioner unattended during installation.

  • Measure the distance between the right side arm hinge and the closest part of the window frame. Add 1/4 in. to this distance and cut the side arm foam block to width.


  • Apply window sealing foam to the side arm foam block as shown. Note that the window sealing foam attaches to the side next to your air conditioner.


  • Insert a side arm foam block into the side arm hinge until the top front of the side arm foam is flush with the top of the hinge.


  • Repeat steps 1 through 3 for the left side of your air conditioner.
  • Remove the two 1/2 in. screws from the top left and right sides of your air conditioner.

CAUTION: The factory installed 1/2 in. screws must be re-used to secure the anti-tip brackets. Failure to use these screws could result in damage to your air conditioner.

  • Extend the anti-tip brackets (one on each side of your air conditioner) into the window tracks (the vertical track in which your window slides up and down) until they stop.


  • Secure the brackets in place using the screws you removed.


  • Install a strip of window sealing foam to the bottom of your lower window sash, sealing any small gaps between the window and your air conditioner, then close the window and check for gaps.
  • Fill any gaps with the included foam, as needed.
  • Extend the integrated window locks (located in the U channel) until they contact the window. For additional security, you can install the optional sash lock.


  • To secure the lower sash in place, attach the right angle sash lock with 1/2 in. type A screws.


  • Cut strips of window sash foam and insert them in the space between the upper and lower sashes.


  • As a final check, review the installation and check for any gaps or openings. Seal any gaps with additional sealing foam (provided), to make sure that there are no leaks.


Using your air conditioner


  • If your air conditioner turns off unexpectedly due to a power outage, it will automatically restart with the previous settings when the power resumes.
  • The cooling circuit has an automatic three minute delay if your air conditioner is turned off and on quickly. This prevents overheating of the compressor and possibly tripping the circuit breaker. The fan continues to run during this time.
  • The relative humidity of the room should be less than 80%. If the unit is used in a condition with a relative humidity over 80%, water will condense on the surface of your air conditioner.
  • For optimum performance, outdoor temperatures should be from 64° F to 109° F (18° C to 43° C), and indoor temperatures should be from 60° F to 90° F (16° C to 32° C).

You can control your air conditioner by using the control panel on the front of the unit or by using the remote control. If using the remote control, always point it at the control panel on your air conditioner.

Using your air conditioner for the first time
  • Plug in your air conditioner (be sure to follow the power cord instructions on page 4).
  • Turn the power on to your air conditioner using the ON/OFF button.
  • Select the Cool mode setting.
  • Adjust the louvers for comfortable air flow (see Controlling air flow on page 29).
  • Make sure that the air flow, both inside and outside, is not obstructed.
  • Once the room has cooled, adjust the thermostat to a comfortable setting.
