INSTALLATION
These instructions explain the recommended method of
installation of the SA electric cooling unit and associated
electrical wiring.
This unit is designed and approved for use as a self-
contained air-to-air air conditioning system.
The units are factory equipped with a transformer and
blower control for applications without auxiliary heat.
Electric heat accessory kits (PHK) can be ordered for field
installation of additional heat where required.
These instructions, and any instructions packaged with
mating components and/or accessories, should be care-
fully 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.
IMPORTANT: This product has been designed and manufac-
tured 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 effi-
ciency 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 pro-
vided. Maintain minimum clearances as shown in Figure 1
and Table 1 and install the unit in level position. Isolate the
base from the building structure to avoid possible transmis-
sion 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
dimension across the unit
must be used across the top
of the unit. Recommended spreader length: 3 ton and smaller
package units – 44", 3.5 ton and larger units – 54".
