(f) Installation Clearance
Refer diagram below for the space required around the unit. Note that:-
(a) All dimensions shown are in mm.
(b) All space value shown are minimum clearance required for the unit.
(c) Unit shown in the diagram is A5RT90BR. Other models shall follow the same clearance.
(d) Unit Lifting
Holes at 4 corners of the unit base are used for unit lifting
purpose.
The spreader bar shall be slightly wider than the unit width.
The insulation should be added at 4 corners of the chain
to prevent the damage of the panel when lifting.
Note:
Unit shown in diagram is A5RT90BR.
Other models will follow the same method in lifting.
(e) Drain Piping
•
A 1" MPT condensate drain fitting is provided. The
drain pipe can be led out at the front side.
•
The drain pipe must be provided with a trap on the
outside of the unit and also installed at an incline

•
To prevent condensate formation and leakage,
provide the drain pipe with insulation to safeguard
against sweating.
