FEATURES
INSTALLATION INSTRUCTIONS
This unit has many features which are different than those found
on conventional units. The servicer must be familiar with these
features in order to properly service the unit.
To ensure that the unit operates safely and efficiently, it must
be installed, operated and maintained according to these installation and operating instructions and all local codes and ordinances or, in their absence, with the latest edition of the
National Electric Code. The proper installation of this unit is
described in the following sections. Following the steps in the
order presented should ensure proper installation.
• Random restart delay - These units employ a random reset
timer which delays unit operation up to 3 minutes following
initial power application. Electronic thermostats may also
employ internal reset timers which may further delay any
changes which are made to the operation of the unit.
Pre-installation Considerations
• Automatic 3-minute compressor lockout - After the compressor cycles off, it will not restart for three minutes. Additional delays may be experienced if using an electronic digital thermostat.
• Ensure that properly sized duct work is in place to mate to
the supply connection on the SPVU.
• Remove the two clips holding the unit to the shipping pallet
and remove unit from the shipping pallet.
• Low ambient compressor lockout - When the outdoor ambient temperature is below 40 degrees F, the low ambient
compressor lockout switch will keep the compressor from
energizing in either cooling or heat pump mode.
• Before setting unit into closet, remove upper side access
panels and inspect the evaporator blower to ensure that the
wheel turns freely without rubbing on the housing.
• Direct drive, multi-speed blower - The proper speeds have
been preset at the factory for heating and cooling. Refer to
wiring diagram for recommended blower speeds for specific
models.
• Remove the styrofoam shipping block supporting the blower
assembly and replace the upper access panels.
• Condensate Drain - This unit comes with factory installed
drain tubing installed on the bottom of the unit. This tubing
drains from a trap at the bottom of the condenser section.
• Check all electrical connections and ensure the condenser
fan turns freely. Note nameplate voltage, amperage and
fuse size for proper power supply.
• Remove front access panel and remove packing and quick
disconnect plug.
• If ducted return air is required, bend out the intake air flanges
90° away from the unit.
LOCATION
• A outdoor air vent panel is located on the lower left side
unit. Remove one screw and rotate the plate to expose the
desired amount of vent opening. Tighten the remaining
screw. Place the removed screw in the open screw hole on
the unit.
Ducted
Return Air
Flanges
Provisions should be made to allow access to the indoor side of
the unit for installation and inspection. The closet or access
panel opening must be centered with the exterior wall opening
and at least 24” wide by 84” tall. Three (3) inches of unobstructed space is required on all sides of the SPVU to allow for
adequate air flow. At least 27 inches of unobstructed space
should be provided in front of the access door to permit removal
of the unit should repair and inspection be required.

UNIT ACCESSORIES
This unit is designed for through-the-wall installation in new or
existing buildings. To complete the installation of this unit, a
wall sleeve, an architectural grille, thermostat and a filter are
required.

• Ensure that the wall sleeve is installed squarely and is secure before installing the unit.
• Ensure the sleeve seal on the wall sleeve is properly secured
and aligned.
• Ensure the architectural or outdoor grille is installed.
• Ensure a minimum clearance of three (3) inches around the
unit for adequate airflow.
• Ensure the condensate drain is unobstructed and leakfree.
NOTE: The wall sleeve has a 3/4 NPT nipple located in the bottom
for connection to the drain. A trap may be required in the
condensate drain line to prevent sewer gas from escaping into the
room.
SLEEVE INSTALLATION
Refer to installation instructions packed with wall sleeve to
assemble and mount it in the wall. Ensure that the construction
debris guard is removed and that the bottom of the wall sleeve
is pitched 1/2 bubble toward the outside of the building. This
angle forces any rain water that might enter to drain to the
outside. Also inspect the bottom of the wall sleeve pan and
drain. They should be clear of obstruction and operational.
Figure 3
2. Connect properly sized electrical service to the quick disconnect.
3. Seal any openings that may exist. If the unit is not completely sealed, water and/or outside air could infiltrate the
closet and cause the unit to malfunction.
4. Install ductwork onto unit discharge and ensure that the connection is leak free. A flexible boot connection may be desirable to provide for more convenient installation and removal from the unit.
IMPORTANT NOTE: Check the indoor and outdoor grilles for
obstructions to air flow. The unit must be located where
curtains, furniture, trees, or other objects cannot block the air
flow to and from the unit. If air is obstructed and/or deflected
back into the unit, the air conditioner’s compressor may cycle on
and off rapidly. This could damage the compressor.
1/2 Bubble Tilt
INTAKE AIR FILTER INSTALLATION
An intake air filter is required for this unit. Do not use pleated
or media filters. Do not operate the unit without one. An intake
air filter, filter bracket and clip are shipped with the unit to
complete this installation.

WARNING
THIS AIR CONDITIONER IS NOT MEANT TO PROVIDE UNATTENDED COOLING OR
LIFE SUPPORT FOR PERSONS OR ANIMALS WHO ARE UNABLE TO REACT TO
THE FAILURE OF THIS PRODUCT.
THE FAILURE OF AN UNATTENDED AIR CONDITIONER MAY RESULT IN EXTREME
HEAT IN THE CONDITIONED SPACE CAUSING OVERHEATING OR DEATH OF
PERSONS OR ANIMALS.
PRECAUTIONS MUST BE TAKEN TO WARN OFF OR GUARD AGAINST SUCH AN
OCCURRENCE.
All wiring must comply with local and national code requirements. Any alteration of the internal wiring will void UL
certification and manufacturer’s warranty.
Nameplate data indicates the operating voltage, phase, ampacity,
maximum over current protection and minimum voltage. Units
must never be installed or operated where voltage exceeds the
nameplate voltage by more than 10%. Failure of the compressor
as a result of operation with improper voltage voids the compressor replacement warranty.
The unit comes with a factory-supplied quick disconnect, however, the contractor is responsible for providing over current
protection on the branch circuit. Refer to the unit wiring
diagram for single point electrical connection.
These units are provided with a Class 2 transformer for 24 volt
control circuits. Should any add-on equipment also have a Class
2 transformer furnished, care must be taken to prevent interconnecting outputs of the two transformers by using a thermostat
with isolating contacts.
