Installation Manual
• Remove the terminal box lid. Connect the single phase power supply (SINGLE PHASE 50Hz 240V) to con-
nections No.1 and No.2 on the terminal block for wiring the units. Do not connect to No.3 of the terminal
block for wiring the units. (The drain pump will not operate.) Connect the ground wire firmly. When carrying
out wiring work around the terminal box, make sure none of the connectors come undone. Be sure to attach
the terminal box lid before turning on the power.
• Put approximately 1000cc of water into the drain pan through the blow-off mouth on the left-hand side of the
drain socket. Make sure not to pour water over the drain pump or any electric parts including those of the
drain pump.
• When the power is turned on, the drain pump will operate and you can check the draining of water through
the transparent part of the drain socket. (The drain pump will stop automatically in 10 minutes.)
After checking the draining of water, mount the thermal insulation material for drainage (14) and thermal
insulate the drain socket.
• After confirming drainage (Fig.23, Fig.24), turn off the power and remove the power supply.
• Attach the terminal box lid as before.
