INSTALLATION
These instructions, and any instructions packaged with
mating components and/or accessories, should be carefully
read prior to beginning installation. Note particularly any
CAUTIONS or WARNINGS in these instructions and all
labels on the units.
These instructions are intended as a general guide only, for
use by qualified personnel and do not supersede any national
or local codes in any way. Compliance with all local, state,
provincial, or national codes pertaining to this type of equipment
should be determined prior to installation.
These instructions explain the recommended method of
installation of the PCE electric cooling unit and associated
electrical wiring.
The PCE unit is designed and approved for use as a self-
contained air-to-air air conditioning system.
The unit is factory equipped with a transformer and blower
control for applications without auxiliary heat. An electric heat
accessory kit (PHK) can be ordered for field installation of
additional heat where required.
IMPORTANT: The 15 SEER models have been designed
and manufactured to meet ENERGY STAR criteria for energy
efficiency. However, proper refrigerant charge and proper air
flow are critical to achieve rated capacity and efficiency.
Installation of this product should follow the manufacturer’s
refrigerant charging and air flow instructions. Failure to
confirm proper charge and airflow may reduce energy
efficiency and shorten equipment life.
Inspection of Shipment
Upon receipt of equipment, carefully inspect it for possible
shipping damage. If damage is found, it should be noted on
the carrier’s freight bill. Take special care to examine the
unit inside the carton if the carton is damaged. File a claim
with the transportation company.
If any damages are discovered and reported to the carrier
DO NOT INSTALL THE UNIT, as claim may be denied.
Check the unit rating plate to confirm specifications are
as ordered.
Limitations
The unit should be installed in accordance with all national
and local safety codes.
Limitations of the unit and appropriate accessories must also
be observed.
The unit must not be installed with any ductwork in the
outdoor air stream. The outdoor fan is not designed to
operate against any additional static pressure.
Location
The unit is designed to be located outdoors with sufficient
clearance for free entrance to the air inlet and discharge air
openings. The location must also allow for adequate service
access.
The unit must be installed on a solid foundation that will not
settle or shift. Adequate structural support must be provided.
Maintain minimum clearances as shown in Table 1 and install
the unit in level position. Isolate the base from the building
structure to avoid possible transmission of sound or vibration
into the conditioned space.
Avoid placing the unit near quiet areas such as sleeping
quarters or study rooms. Normal operating sound levels
may be objectionable if the unit is placed near certain rooms.
Do not permit overhanging structures or shrubs to
obstruct condenser air discharge inlet or outlet.
For improved start-up performance, the indoor coil
should be washed with suitable detergent to remove
any residue from manufacturing processes.
Exercise care when moving the unit. Do not remove any
packaging until the unit is near the place of installation. An
accessory lift kit can be purchased to aid in rigging (see
Figure 1). Spreaders whose length exceed the largest
