INSTALLATION OF THE UNIT
English
(A) Location For Installation
Install the unit in such way that air distributed by the unit cannot be drawn in again (as in the case of short
circuit of discharge air). Allow suf
fi
cient space for maintenance around the unit.
When two or more units are installed in a location, they must be positioned such that one unit will not be
taking the discharge air from another unit.
Ensure that there is no obstruction of air
fl
ow into or out of the unit. Remove obstacles which block air intake
or air discharge.
The location must be well ventilated, so that the unit can draw and distribute plenty of air.
The unit is recommended to install in:-
A place capable of bearing the weight of the unit and isolating noise and vibration.
A place where has adequate drainage.
A place where the unit will not be buried in snow.
A place where air outlet port is not exposed to strong wind.
A place where the air discharge and operating sound level will not annoy the neighbours.
The location where it is not accessible by general public.
(B) Duct Construction
This unit are equipped with supply and return air openings. Duct connection to the unit should be made with
duct
fl
anges and secured directly to the air openings with
fl
exible duct connectors to avoid normal noise
transmission.
To prevent air leakage, all duct seams should be sealed.
Ducts in the spaces that not air-conditioned, must be insulated.
Ducts exposed to the outside must be weather proofed.
Ducts that entering building through the roof, the entering should be sealed with weather stripping to prevent
rain, sand, dust etc, from entering the building.
Correct size of
fi
lter must be installed at the return air duct.
(C) 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 UATQ210/240C. Other models will follow the same method in lifting.
