1.2  Unit Support

1.  

The 

fi

 gure shows the use of the roof curb for 

mounting these units.

2.   The curb should be sealed and 

fi

  xed to the roof by 

weather stripping. A suggested means of sealing 
the unit and roof curb as shown in the left.

1.3  Duct Construction

These unit are equiped with supply and return air openings. Duct connection to the unit should be made with duct flanges 
and secured directly to the air openings with flexible 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 the rain, 
sand, dust etc. from entering the bulding.
Correct size of filter must be install at the return air duct.

1.1  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.
