REFRIGERANT PIPE
• Insulate and tape both the gas piping and
liquid piping.
NOTICE
Common direction of drain and piping. Tape the tubing, drain hose and the
connecting cable. Be sure that the drain hose is located at the lowest side of the
bundle. Locating at the upper side can cause drain pan to overflow inside the unit.
NOTICE
If the drain hose is routed inside the room, insulate the hose with an insulation material*
so that dripping from "sweating"(condensation) will not damage furniture or floors.
*Foamed polyethylene or equivalent is recommended.
Checking the Drainage
1) Checking the Drainage
1. Remove the Air Filter.
2. Check the drainage.
• Spray one or two glasses of water upon
the evaporator.
• Ensure that water flows drain hose of
indoor unit without any leakage.
Insulate the joint and tubes completely.
All thermal insulation must comply with local requirement.
