Installation instructions

Outdoorunitinstallation

1.Install Drain Port and Drain Hose (for heat-pump model only)

The condensate drains from the outdoor unit when the unit operates

 

 

in heating mode. In order not to disturb your neighbor and protect

 

 

the environment, install a drain port and a drain hose to direct the

 

 

condensate water. Just install the drain port and rubber washer to

 

 

the chassis of the outdoor unit, then connect a drain hose to the

 

Washer

port as the right figure shown.

2. Install and Fix Outdoor Unit

 

(prepare by user)

 

 

Fix with bolts and nuts tightly on a flat and strong floor.

 

 

If installed on the wall or roof, make sure to fix the supporter well to prevent it

 

from shaking due to serious vibration or strong wind.

 

 

3. Outdoor Unit Piping Connection

 

 

Remove the valve caps from the 2-way and 3-way valve.

Connect the pipes to the 2-way and 3-way valves separately according to the required torque.

4. Outdoor Unit Cable Connection (see previous page)

Airpurging

The air which contains moisture remaining in the refrigeration cycle may cause a malfunction on the compressor. After connecting the indoor and outdoor units, evacuate air and moisture from refrigerant cycle using a vacuum pump, as shown below.

Note: To protect the environment, be sure not to discharge the refrigerant to the air directly.

See next page for air purging steps.
