Installation Of The Indoor Unit - Daikin R410A Technical Manual

Installation Of The Indoor Unit

Preliminary Site Survey
Be sure to read this manual before installing the air-conditioner indoor unit.
• Voltage supply fluctuation must not exceed +10% of rated voltage. Electricity supply lines must be
independent of welding transformers which can cause high supply fluctuation.
• Ensure that the location is convenient for wiring, piping and drainage.
Standard Mounting
Ensure that the overhead supports are strong enough to hold the weight of the unit. Position the hanger
rods (wall mounting bracket for floor standing), and check for its alignment.
Also, check that the hangers are secured and the base of the fan coil unit is leveled in both horizontal
directions.

Please ensure that the following steps are taken:
- The drain pipe slope shall be kept at least 1:100.
- Provide clearance for easy servicing and optimal air flow as shown in Figure B.
- The indoor unit must be installed such that there is no short circuit of the cool discharge air with the
warm return air.
- Do not install the indoor unit where there is direct sunlight shining on the unit. The location should be
suitable for piping and drainage installation. The unit must be a large distance away from the door.
