Installation Procedure

(2) Check if water drainage is smooth after installation.

Charge, through air outlet or inspecting hole, 1200ccd water to see water drainage.

(Just take HBU-28HH03 for example. For HBU-42CH03, HBU-42HI03, HBU-48CH03 there is no inspecting hole).

After wiring

Check water drainage in cooling operation. See also 10 test run.

Method of water charging

Self-provided stiff pipe

When wiring is not complete

Remove cover of control box, short connect "CHECK" terminal of the indoor unit, which is on the uper part of indoor unit PCB.

Connect 1PH power to terminal 1 and 2 on terminal block.

Note: In this operation, fan will be running. Upon confirmation of a smooth water

drainage, be sure to cut off power supply and remove short connection of "CHECK" terminal.

Water drainage port for maintenance

(Drain water from this hole)

100mm

Watering can of plastic pipe should be about 100 mm long
