Safety Considerations

Read these Safety Considerations for Operations carefully before operating an air conditioner or heat pump. Make sure that the unit operates properly during the startup operation. Instruct the user on how to operate and maintain the unit. Inform users that they should store this operation manual with the installation manual for future reference. Meanings of DANGER, WARNING, CAUTION, and NOTE Symbols:

DANGER

• Do not install the unit in an area where flammable materials are present due to risk of explosion resulting in serious injury or death.
• Any abnormalities in the operation of the air conditioner or heat pump, such as smoke or fire, could result in severe injury or death. Turn off the power and contact your dealer immediately.
• Refrigerant gas may produce toxic gas if it comes into contact with fire, such as from a fan heater, stove, or cooking device. Exposure to this gas could cause severe injury or death.
• For refrigerant leakage, consult your dealer. Refrigerant gas is heavier than air and replaces oxygen. A massive leak could lead to oxygen depletion, especially in basements, and an asphyxiation hazard could occur leading to serious injury or death.
• If equipment utilizing a burner is used in the same room as the air conditioner or heat pump, there is the danger of oxygen deficiency which could lead to an asphyxiation hazard resulting in serious injury or death. Be sure to ventilate the room sufficiently to avoid this hazard.
• Safely dispose of the packing materials. Packing materials, such as nails and other metal or wooden parts, may cause stabs or other injuries.
• Tear apart and throw away plastic packaging bags so that children will not play with them. Children playing with plastic bags face the danger of death by suffocation.

WARNING

• Contact your dealer for repair and maintenance. Improper repair and maintenance may result in water leakage, electric shock, and fire. Only use accessories made by Daikin that are specifically designed for use with the equipment and have them installed by a professional.
• Contact your dealer to move and reinstall the air conditioner or heat pump. Incomplete installation may result in water leakage, electric shock, and fire.
• Never let the indoor unit or the remote controller get wet. Water can cause an electric shock or a fire.
• Never use flammable spray such as hair spray, lacquer, or paint near the unit. Flammable spray may cause a fire.
• When a fuse blows out, never replace it with one of incorrect ampere ratings or different wires. Always replace any blown fuse with a fuse of the same specification.
• Never inspect or service the unit by yourself. Contact a qualified service person to perform this work.
• Turn off all electrical power before doing any maintenance to avoid the risk of serious electric shock; never sprinkle or spill water or liquids on the unit.
• Do not touch the switch with wet fingers. Touching a switch with wet fingers can cause electric shock.
• Do not allow children to play on or around the unit to prevent injury.
• The heat exchanger fins are sharp enough to cut. To avoid injury wear gloves or cover the fins while working around them.
• Do not put a finger or other objects into the air inlet or air outlet. The fan is rotating at high speed and will cause injury.
• Check the unit foundation for damage on a continuous basis, especially if it has been in use for a long time. If left in a damaged condition the unit may fall and cause injury.
• Never touch the internal parts of the controller. To check and adjust internal parts, contact your dealer.

Note for Multi System

A multi system has one outdoor unit connected to multiple indoor units.

Selecting the operation mode

When the priority room setting is active but the set unit is not operating or when the priority room setting is inactive When more than one indoor unit is operating, priority is given to the first unit that was turned on. In this case, set the units that are turned on later to the same operation mode as the first unit. Otherwise, they will enter the standby state, and when using the wired remote controller the centralized control icon “CENTRAL CONTROL” will light up; this does not indicate malfunction.

NOTE

Notes on operation mode for a multi system

• COOL, DRY and FAN operation may be used at the same time.
• AUTO operation automatically selects COOL operation or HEAT operation based on the indoor temperature. Therefore, AUTO operation is available when selecting the same operation mode as that of the room with the first unit to be turned on.

CAUTION

• Normally, the operation mode in the room where the unit is first started is given priority, but the following situations are exceptions to this rule.
• If the operation mode of the first room is FAN operation, then using HEAT operation in any room after this will give priority to HEAT operation. In this situation, the indoor unit operating in FAN mode will switch to standby, and when using the wired remote controller the centralized control icon “CENTRAL CONTROL” will light up

GHT QUIET mode (Available only for COOL operation)

• NIGHT QUIET mode requires initial programing during installation. Please consult your retailer or dealer for assistance.
• NIGHT QUIET mode reduces the operation noise of the outdoor unit during the night-time hours to prevent annoyance to neighbours.
• NIGHT QUIET mode is activated when the temperature drops 43°F (6°C) or more below the highest temperature recorded that day. When the temperature difference between the current outdoor temperature and the maximum outdoor temperature becomes less than 39°F (4°C), this function will be canceled.
• NIGHT QUIET mode slightly reduces the cooling efficiency of the unit

OUTDOOR UNIT QUIET operation (Function unavailable in the FDMQ series)

For details on OUTDOOR UNIT QUIET operation, refer to the operation manual included with the remote controller. When the priority room setting is active but the set unit is not operating or when the priority room setting is inactive When using the OUTDOOR UNIT QUIET operation feature with a multi system, set all indoor units to OUTDOOR UNIT QUIET operation using their remote controllers. When canceling OUTDOOR UNIT QUIET operation, simply cancel the mode on one of the operating indoor units using their remote controller. However OUTDOOR UNIT QUIET operation will remain displayed on the remote controllers for the other rooms. We recommend you cancel operation in all rooms using their remote controllers. With the priority room setting active Refer to “Priority room setting” on the next page

COOL/HEAT mode lock

The COOL/HEAT mode lock requires initial programing during installation. Please consult your authorized dealer for assistance. The COOL/HEAT mode lock sets the unit forcibly to either COOL or HEAT operation. This function is convenient when you wish to set all indoor units connected to the multi system to the same operation mode.

NOTE

• The COOL/HEAT mode lock cannot be activated together with the priority room setting.

Priority room setting

• The priority room setting requires initial programing during installation. Please consult your authorized dealer for assistance.
• The room designated as the priority room takes priority in the following situations.

Operation mode priority

• As the operation mode of the priority room takes precedence, you can select a different operation mode from other rooms.

[Example]

• Room A is the priority room in this example.
• When COOL operation is selected in room A while operating the following modes in room B, C and D:

Operation mode in room B, C and D Status of room B, C and D when the unit in room A is in COOL operation
COOL or DRY or FAN The current operation mode is maintained.
HEAT The unit enters the standby mode. Operation resumes when the room A unit stops operating.
AUTO If the unit is set to COOL operation, it continues. If the unit is set to HEAT operation, it enters the standby mode. Operation resumes when the room A unit stops operating.

Priority when OUTDOOR UNIT QUIET operation is used (Function unavailable in the FDMQ series)

[Example]

• Room A is the priority room in this example.
• Just by setting the unit in room A to QUIET operation, the air conditioner starts OUTDOOR UNIT QUIET operation.
• You do not have to set all the indoor units in operation to OUTDOOR UNIT QUIET operation.
