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 sufﬁ 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.

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 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 the rain,

sand, dust etc. from entering the bulding.

•

Correct size of ﬁ lter must be install at the return air duct.
