Corroding copper pipes or soldered parts may result in specified by Daikin are used, fire or explosion may occur. refrigerant leakage. • Do not use means to accelerate the defrosting process (if possible) (c) Near machinery emitting electromagnetic waves.
Safety Considerations • Only use tools for R32, such as a gauge manifold, NOTE charge hose, gas leak detector, reverse flow check valve, • The indoor unit should be positioned where the unit and refrigerant charge base, vacuum gauge, or refrigerant interunit wires (outdoor to indoor) are at least 3.3ft (1m) recovery equipment.
Indoor Unit Installation Diagram How to attach the indoor unit mounting plate Mounting Hook the hooks of the bottom frame should be installed on a plate to the mounting plate. wall which can support the If the hooks are difficult to hook, weight of the indoor unit.
Indoor Unit Installation Installing the mounting plate • The mounting plate should be installed on a wall which can support the weight of the indoor unit. 1) Temporarily secure the mounting plate to the wall, make sure that the panel is completely level, and mark the drilling points on the wall.
Installing the indoor unit In the case of bending or curing refrigerant pipes, keep the following precautions in mind. Abnormal sound may be generated if improper work is conducted. • Do not strongly press the refrigerant pipes onto the bottom frame. •...

Indoor Unit Installation 2) Attach the drain hose to the underside of the refrigerant pipes with adhesive vinyl tape. Remove pipe port cover here for left-side piping. Left-side piping Left-back piping Remove pipe port cover here for left-bottom piping. Left-bottom piping 3) Shape the refrigerant pipes along the pipe path marking on the mounting plate.
Wiring Refer to the installation manual for the outdoor unit also. WARNING • Do not use tapped wires, extension cords, or starburst connections, as they may cause overheating, electric shock, or fire. • Do not use locally purchased electrical parts inside the product. (Do not branch the power for the drain pump, etc., from the terminal block.) Doing so may cause electric shock or fire.
Indoor Unit Installation Drain piping 1) Connect the drain hose, as shown below. • Avoid placing the end of the drain hose in a drainage location that could cause bad odors or corrosive gas to flow backward into the outlet. •...
Refrigerant Piping Work WARNING • Do not apply mineral oil to the flare. • Prevent mineral oil from getting into the system as this would reduce the service life of the units. • Never use piping which has been used for previous installations. Only use parts which are delivered with this unit. •...

Refrigerant Piping Work Selection of copper and heat insulation materials When using commercial copper pipes and fittings, observe the following: Gas pipe • Insulation material: Polyethylene foam Liquid pipe Heat transfer rate: 0.041 to 0.052W/mK (0.024 to 0.030Btu/fth°F (0.035 to 0.045kcal/mh°C)) Be sure to use insulation that is designed for use with HVAC Systems.
Installation Tips Removing and installing the front panel • Removal method 1) Hold the front panel by the sides and pull it open until it stops. 2) While pushing the left side front panel shaft outward, push up the Front panel shaft front panel and remove it.
Installation Tips How to set the different addresses When 2 indoor units are installed in one room, the 2 wireless remote controllers can be set for different addresses. Change the address setting of one of the 2 units. When cutting the jumper, be careful not to damage any of the surrounding parts.
Trial Operation and Testing Trial operation and testing • Trial operation should be carried out in either COOL or HEAT operation. 1-1. Measure the supply voltage and make sure that it is within the specified range. 1-2. In COOL operation, select the lowest programmable temperature; in HEAT operation, select the highest programmable temperature.
