• As shown in 3, install a collecting pipe about 10cm below the drain
ports and give it a downward pitch of more than 1/100. This collect-
ing pipe should be of VP-30.
• Set the end of drain piping in a place without any risk of odor genera-
tion.
• Do not put the end of drain piping into any drain where ionic gases
are generated.

5. Electrical work

s Consult all related regulations and power companies before-
hand.
Warning:
Electrical work should be handled by qualified electric engineers
in accordance with all related regulations and attached instruction
manuals. Special circuits should also be used. If there is a lack of
power capacity or a deficiency in electrical work, it may cause a
risk of electric shock or fire.
s Connect all wires without looseness.
• Fix power source wiring to control box by using buffer bushing for
tensile force (PG connection or the like).

• Although it is free to choose to take out piping in any direction, be
sure to observe the instructions above.
• When using an optionally available drain-up mechanism, follow its
instruction manual for drain piping.

2. Discharge test
After completing drain piping work, open the BC controller panel, fill water,
and test drain discharge. At this moment, check to see that there is no
water leakage from the connections.
3. Insulating drain pipes
Provide sufficient insulation onto the drain pipes just as for refrigerant
pipes.
Caution:
Be sure to provide drain piping and heat-insulate it in order to pre-
vent dew condensation. If there is a deficiency in piping work, it
may cause a risk of water leakage and so wet your property.
