Water drainage
When lengthening the drain pipe, please must do heat insulation for the flexible pipe
lengthened part of the indoor side.
Do not make the lengthened drain pipe loose.
No draining barriers in piping the drain pipes.
When the drain pipes connect to the outdoor, it should be wrapped around with heat
insulation material, and rolled on the surface by packing belts to avoid air come in and
cause condensation.
Laying the dram pipe should be downward slopping, do not make rising drainage.
Do not place the end of the drain pipe in the water.
3.9 Field wiring
The maximum allowed voltage fluctuation is ± 10%.
Be sure unit is correctly earthing.
Be sure equipped electric leakage switch, main switch and fuse. The capacity of fuse should
be calculated as followed: the max. ampacity= (1.5~3)× the max. current of air conditioner +
total current of other electrical equipment. Cable introduction:
