Installation Of Indoor Unit - Acson CB Serie Installationsanleitung

1. Preliminary Site Survey
• Electrical supply and installation is to conform to local
authority's (e.g. National Electrical Board) codes and
regulations.
• Voltage supply fluctuation must not exceed ±10% of
the rated voltage. Electricity supply lines must be
independent of welding transformers which can cause
high supply fluctuation.
• Ensure that the location is convenient for wiring,
piping and drainage.

Please ensure that the following steps are taken:
• Check the gradient for drainage flow as recommended
in Figure B.
• Provide clearance for easy servicing and optimal air flow
as shown in Figure C.
• The indoor unit must be installed such that there is no
short circuit of the cool discharge air with the warm
return air.
• Do not install the indoor unit where there is direct
sunlight shining on the unit. The location should be
suitable for piping and drainage installation. The unit
must be a large distance away from the door.
3. Semi-Enclose Mounting
• In case the unit is to be half recessed into false ceiling, please check the unit is well aligned.
• Provide the installation space as shown in Figure D.

• Ensure that the overhead supports are strong enough to
hold the weight of the unit.
• Position the hanger rods (wall mounting bracket for floor
standing), and check for its alignment with the unit.
• Also, check that the hangers are secured and the base of
the fan coil unit is leveled in both horizontal directions,
taking into account the gradient for drainage flow as
recommended in Figure B.
