6. DRAIN PIPING WORK
1. Rig the drain piping.
Rig the drain line to ensure proper drainage. Also, observe the following to prevent leaks.
CAUTION
• Bundle the drain pipe to the refrigerant pipes as shown at right or take other means to anchor it down, so
as not to apply pressure to the hose inside the unit. This is necessary to prevent the drain pipe from
disconnecting and to ensure proper insulation. Keep the drain pipe sloping at a minimum 1/100 gradient, to
prevent air pockets.
• The drain pipe may be clogged if water accumulates in the drain pipe.
• Condensate can form on the pipe and leak from the unit. Therefore, definitely insulate the pipe in at least
the below two places.
•All pipe in the room and inside the unit.
•At connection between the unit’s drain hose and building drain pipe.
2. After rigging the drain hose, check that drainage flows smoothly and that water does
not leak from connections.
•Carefully pour approximately
1,000cc of water through the air
discharge outlet so that it falls
directly onto the heat
exchanger at an angle without
splashing. (See figure at right.)
* If water is poured too fast or if
water pressure is too high, the
water will pass through the
heat exchanger and drip on
the fan motor below it.
* If water gets on the inner front
wall, it will leak onto the floor.
CAUTION
• In order to prevent the intrusion of small animals, seal the pipe penetration hole with putty or heat insulating
material (field supply).
• Drain piping connections
Do not connect the drain piping directly to sewage pipes that smell of ammonia. The ammonia in the
sewage might enter the indoor unit through the drain pipes and corrode the heat exchanger.
