CAUTION
•
Install the drain lift pipes no higher than 21".
•
Install the drain lift pipes at a right angle to the indoor unit and no more than 12" from the unit.
•
To prevent air bubbles, install the drain hose level.
•
The incline of drain hose should be no more than 3"so that the drain socket does not have to
withstand additional force.
•
To ensure a downward slope of 1:100, support the drain line every 3'.
•
When unifying multiple drain pipes, install the pipes as shown in figure below. Select
converging drain pipes whose gauge is suitable for the operating capacity of the unit.
•
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.
