Field Piping and Wiring
•
Insulate the clamp bracket and drain hose from the bottom using the included sealing pad (8).
(Refer to Fig. 21)
•
Be sure to insulate all drain piping running indoors.
•
Do not allow any slack to gather in the drain hose inside the indoor unit. (Refer to Fig. 22)
(Slack in the drain hose can cause the suction grille to break.)
(2) Check to make sure the drain flows smoothly after piping is complete.
•
Slowly pour 600 ml of drain-checking water into the drain pan through the air outlet.
Caution
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.
Air outlet
Plastic container
for pouring
Make sure not to splash the water.
