Pre-Installation
• the unit is set on the roof curb, and temporary heat is provided in the building. Isolate all side
panel service entrances and base pan openings (e.g., conduit holes, S/A and R/A openings, and
flue openings) from the ambient air until the unit is ready for start-up.
Note: Do not use the unit’s heater for temporary heat without first completing the start-up
procedure detailed under “Starting the Unit”.
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, p. 13 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.
