2. After piping work is finished, check if drainage flows
smoothly.
Open the water inlet lid, add approximately 2 l of water
gradually and check the drainage flow.
Method of adding water. See figure 13.
1 Drain pipe
2 Service drain outlet with rubber plug. Use this outlet to drain
water from the drain pan.
3 Plastic container for pouring
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.
When electric wiring work is finished
Check drainage flow during COOL running, explained in the chapter
"Test operation" on page 8.
When electric wiring work is not finished
Remove the switch box lid and connect the power supply and
remote controller to the terminals.
See figure 22.

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 HR box are properly matched. If wiring and
piping between the outdoor unit and an indoor unit are
mismatched, the system may cause a malfunction.
Refer to the installation manual attached to the outdoor unit for
the size of power supply electric wire 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 lightning
storms.
