LOCATION & CLEARANCES
NOTE: To ensure proper condensate drainage, unit must be in-
stalled in a level position.
In installations where the unit is installed above ground level
and not serviceable from the ground (Example: Roof Top
installations) the installer must provide a service platform for
the service person with rails or guards in accordance with local
codes or ordinances.

*PC15/*PH16**H41*
NOTE: Roof overhang should be no more than 36" and
provisions made to deflect the warm discharge air out from the
overhang.
Minimum clearances are required to avoid air recirculation and
keep the unit operating at peak efficiency.
WARNING
TO PREVENT POSSIBLE DAMAGE, THE UNIT SHOULD
REMAIN IN AN UPRIGHT POSITION DURING ALL
RIGGING AND MOVING OPERATIONS. TO FACILITATE
LIFTING AND MOVING IF A CRANE IS USED, PLACE
THE UNIT IN AN ADEQUATE CABLE SLIDE.
Refer to Roof curb Installation Instructions for proper curb in-
stallation. Curbing must be installed in compliance with the
National Roofing Contractors Association Manual.
Lower unit carefully onto roof mounting curb. While rigging
unit, center of gravity will cause condenser end to be lower
than supply air end.

*PC15/*PH16 Package Units are designed for outdoor installa-
tions only in either residential or light commercial applications.
NOTE: To ensure proper condensate drainage, unit must be in-
stalled in a level position.
The connecting ductwork (Supply and Return) can be connected
for horizontal discharge airflow. In the down discharge applica-
tions, a matching Platform/Roof Curb (PCCP101-103) and
Downflow Plenum (PCP101-103) is recommended for horizon-
tal models only.
A return air filter must be installed behind the return air grille(s)
or provision must be made for a filter in an accessible location
within the return air duct. The minimum filter area should not
be less than those sizes listed in the Specification Section.
Under no circumstances should the unit be operated without
return air filters.
A 3/4" - 14 NPT drain connector is provided for removal of con-
densate water from the indoor coil. In order to provide proper
condensate flow, do not reduce the drain line size.
Refrigerant flow control is achieved by use of restrictor orifices.
These models use the FasTest Access Fitting System, with a
saddle that is either soldered to the suction and liquid lines or
is fastened with a locking nut to the access fitting box (core)
and then screwed into the saddle. Do not remove the core
from the saddle until the refrigerant charge has been
removed. Failure to do so could result in property dam-
age or personal injury.
The single phase units use permanent split capacitors (PSC)
design compressors. Starting components are therefore not
required. A low MFD run capacitor assists the compressor to
start and remains in the circuit during operation.
The outdoor fan motor is a single phase capacitor type motors.
