SAFETY INSTRUCTIONS
Read these “SAFETY INSTRUCTIONS for Operations” carefully before installing. After completing the installation, make sure that the unit operates properly during the start-up operation. Instruct the customer on how to operate and maintain the unit. Inform customers that they should store this Operation Manual with the Installation Manual for future reference. Always use a licensed installer or contractor to install this product. Improper installation can result in water or refrigerant leakage, electrical shock, fire, or explosion.
- Do not place flammable materials in direct proximity of the indoor and outdoor unit. There are risks of a
fire resulting in serious injury or death. - Any abnormalities in the operation of the heat pump such as smoke or fire could result in severe injury or
death. If these conditions are present, turn off the power and contact your dealer immediately. - Refrigerant gas may produce toxic gas if it comes in contact with fire, such as from a fan, heater, stove or
cooking device. Exposure to this gas could cause severe injury or death. - For a 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 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 all packing materials. Packing materials, such as nails and other metal or wooden parts,
may cause wounds or other injuries.
PART NOMENCLATURE
MAINTENANCE
- Only a licensed professional contractor should perform routine maintenance and service.
- Only a licensed professional contractor is allowed to install optional parts. Be sure to use the optional parts specified by the manufacturer. Installation of unauthorized parts may result in water leakage, electric shock or fire.
- Do not use flammable material (e.g. hair-spray or insecticide) near the product.
- Do not allow the indoor unit to get wet as it may cause an electric shock or fire.
- Clean the unit only after turning it off and disconnecting the power supply.
- Failure to do so may result in electric shocks or injury
BEFORE CONTACTING YOUR DEALER
Since the system has protection controls, you may encounter the following:
- The heat pump and gas furnace will not switch over each other according to room temperature automatically if the outdoor unit is not configured to automatically switch heat sources. But, the system may be able to automatically switch between of heat pump and gas furnace operation according to outside ambient temperature. In that case, the compressor will stop when the gas furnace will operate.
- The field setting of the switch over temperature might not be exact. This setting can be confirmed and changed
by only your Daikin dealer. - In order to protect the system, a prohibition timer is used to prevent frequent switch over between heat pump and gas furnace. Once the gas furnace lights, the system will not switch over until the pre-determined prohibition time has passed. This setting can be confirmed and changed by your Daikin dealer.
GAS FURNACE LOCKOUT RESET
Furnace lockout is characterized by a non-functioning furnace providing a diagnostic LED code located on the furnace board (contact your Daikin dealer for further assistance). Lockout results when a furnace control detects abnormal conditions. If the furnace is in “lockout,” the following methods can be used to clear the error code.
- Turn the remote controller off to clear the error. If the error isn’t cleared, go to next step.
- Set a setting temperature to maximum, then turn the remote controller on.
- Turn the remote controller off.
- After performing c., turn the remote controller on after approximately 15 seconds.
The procedures b, c, and d will not work during certain outdoor unit operations, i.e. defrost, start-up, stop a compressor, service mode etc.
