(2) Make sure the drain works properly.
•
After drain work is complete, perform a drain
check by opening the front panel,
removing
the air filter
, pouring water into the drain pan,
and making sure water flows smoothly out of
the drain hose.
(Refer to Fig. 19)
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.
Keep in mind that it will become the cause of getting drain pipe blocked if water collects on drain pipe.
7. ELECTRIC WIRING WORK
7-1 GENERAL INSTRUCTIONS
•
All field supplied parts and materials and electric works must conform to local codes.
•
Use copper wire only.
•
For electric wiring work, refer to also “WIRING DIAGRAM” attached to the unit body.
•
For remote controller wiring details, refer to the installation manual attached to the remote controller.
•
All wiring must be performed by an authorized electrician.
•
This system consists of multiple indoor units. Mark each indoor unit as unit A, unit B..., and be sure the
terminal board wiring to the outdoor unit and BS unit are properly matched. If wiring and piping between the
outdoor unit and an indoor unit are mismatched, the system may cause a malfunction.
•
A circuit breaker capable of shutting down power supply to the entire system must be installed.
•
Refer to the installation manual attached to the outdoor unit for the size of power supply wiring connected
to the outdoor unit, the capacity of the circuit breaker and switch, and wiring instructions.
•
Be sure to ground the air conditioner.
•
Do not connect the ground wire to gas pipes, water pipes, lightning rods, or telephone ground wires.
•
Gas pipes: might cause explosions or fire if gas leaks.
•
Water pipes: no grounding effect if hard vinyl piping is used.
•
Telephone ground wires or lightning rods: might cause abnormally high electric potential in the ground
during lighting storms.
