1. Install declination of the indoor unit is very important for the drain of the duct type air conditioner.
2. Minimum thickness of the insulation for the connecting pipe shall be 19mm(1/32 inch).
• The unit must be horizontal or declined to the drain hose connected when fin-
ished installation.
INSULATION, OTHERS
Insulate the joint and tubes completely.
All thermal insulation must comply with local requirement.
INDOOR UNIT
n After all workings are finished, check the working and operation.
• Air distribution ............... Is the air circulation good?
• Drain ............................. Is the drainage smoothly and no sweating?
• Gas leakage ................. Is the piping connection correctly?
• Wiring ........................... Is the wiring connection correctly?
• Lock-bolt ....................... Is the lock-bolt of compressor loosened?
• Insulation....................... Is the unit fully insulated?
• Ground .......................... Is the unit safely grounded?
