(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.

• 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 block wiring to the outdoor unit and BS unit is properly matched. If wiring and piping between the

outdoor unit and 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.

• Lightning rods or telephone ground wires: might cause abnormally high electric potential in the ground

during lightning.
