I Single Package Heat Pumps
While minimum clearances are acceptable for safety rea-
sons, they may not allow adequate air circulation around
the unit for proper operation. Whenever possible, it is desir-
able to allow additional clearance, especially around the
condenser inlet and discharge openings.

Installation
Do NOT install the unit in a location that will permit dis-
charged air from the condenser to recirculate to the con-
denser inlet.
CAUTION
Do NOT operate unit in a corrosive atmosphere con-
taining chlorine, fluorine, or any other corrosive chem-
icals.

CAUTION
Unit will NOT operate properly unless it is installed lev-
el front to rear and side to side.
The slope MUST NOT be greater than 1/8" per foot
(lOmm per meter). For side to side leveling, the control
box side MUST always be lower.
Ground Level Installation
Ground level platform requirements:
The unit MUST be situated to provide safe access for
servicing.
Platform may be made of either concrete or pressure
treated wood and MUST be level and strong enough
to support unit weight.
Position platform separate from building foundation.
Install in well-drained area, with top surface of plat-
form above grade level and above the average winter
snow levels to prevent coil blockage.
Platform MUST be high enough to allow for proper
condensate trap installation and drainage. See Fig-
ure 8 and associated text for more information about
condensate drainage.
