General Information

The manufacturer will not assume any responsibility for equipment damage resulting from condensate accumulation on the unit’s electrical and/or mechanical components.

Unit Clearances

Figure 1 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.
