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.
WHEN ELECTRIC WIRING WORK IS FINISHED
• Check drainage flow during Cooling operation, explained
under "TEST OPERATION".
