Dimensional Data

Below figure illustrates the minimum operating and
service clearances for either a single or multiple unit
installation. These clearances are the minimum
distances necessary to assure adequate serviceability,
cataloged unit capacity, and peak operating efficiency.

Providing less than the recommended clearances may
result in condenser coil starvation, “short-circuiting” of
exhaust and economizer airflows, or recirculation of
hot condenser air.

Figure 1. Typical installation clearance for single and multiple unit applications

NOTES:

1. FOR HORIZONTAL DISCHARGE UNIT,

THIS MEASUREMENT IS REDUCED TO 1’ 6”

TO MINIMIZE DUCT EXTENSION.

2. WHEN EQUIPPED WITH ECONOMIZER

OR BAROMETRIC RELIEF DAMPER,

CLEARANCE DISTANCE IS TO BE 

MEASURED FROM PROTRUDING HOOD

INSTEAD OF BASE.

3. CLEARANCE ISTHE SAME IF ANY

UNIT IS ROTATED 180°.

4. ADDITIONAL CLEARANCE REQUIRED 

WHEN BAROMETRIC DAMPER OR

ECONOMIZER IS INSTALLED.
