STANDARD FEATURES
CABINET
The HP-Series Series heat pump has a cabinet that is constructed of 18 gauge steel
with a polyester powder coated finish that will compliment any decor. The cool blue front
compliments any surrounding space, and is insulated with sound-absorbing insulation
for cool, quiet comfort. All units come equipped with handles and premium swivel
casters for portability and convenient set-up.
DELUXE ELECTRONIC CONTROLLER
Each HP-Series unit is equipped with a deluxe electronic controller. When power is
connected to the unit, the thermostat will control the unit to cool/heat a space to the
desired temperature. The thermostat is also capable of controlling the fan to operate
automatically when needed, or continuously.
One additional feature of the Deluxe Electronic Controller is that it will display a
condition alarm “CON”. “CON” displays when a condensate alarm, or a high pressure
reset condition has been met. To protect the compressor from short-cycling, there is a
built-in time delay.
FAN SPEED CONTROL
One of the features of the electronic controller is that the unit supply fan can be
controlled either automatically or manually. In AUTO mode, the indoor blower will adjust
air flow automatically for added comfort and performance. Or, if desired, the controller
can be set to MANUAL fan mode, and the indoor blower will run continuously at one of
six levels of fan speed.
CONDENSATE TANK/PUMP
HP-Series units come equipped with a means for handling the condensate generated
during the cooling/heating process. All units, except the 5-ton models, come equipped
with a condensate tank. The tank can be easily removed from the unit and emptied as
needed.
The TC-60HP models come equipped with an automatic condensate pump. The pump
comes with a 20 foot long vinyl hose that allows for the removal of the condensate water
to a drain. The automatic pump is capable of a 20ft vertical lift, to handle almost any
installation requirement.
FILTERS
All HP-Series units are equipped with washable filters at the air intakes. Electrostatic
mesh air filters located behind the evaporator return air grille serve to filter the air before
it is cooled/heated, and behind the condenser return air grille to prevent dust build-up.
Both filters can be easily removed and cleaned.
HIGH PRESSURE SAFETY SWITCH
Located on the back of the HP-Series unit is a manual re-set high pressure switch, used
for the protection of the compressor. If the condensing pressure exceeds the limit
setting, the switch will cycle the compressor off, while the evaporator fan remains
running. The display will indicate the default setting “CON”. The compressor can then
be re-started, once the condensing pressure has equalized, by depressing the
“RESET” button.
POWER CORDS
All HP-Series units come standard with a power cord for a convenient connection. All
models, except for the 3-phase units and 5-ton units, are equipped with LCDI for added
safety features.

APPLICATIONS
COOLING MODE—SPOT COOLER
The HP-Series can be used in an open environment to cool specific objects or "spots".
Spot Cooling is a convenient and economical way to provide air conditioning, where
cooling the entire space is impractical. Cool air is discharged from the unit and is
directed where it is needed. Nozzle kits can be used for directional cooling.
AREA COOLER
When the HP-Series is installed in an open area, the condenser exhaust duct directs the
warm air away from the space, allowing the evaporator air to cool the specific area.
ROOM AIR CONDITIONER
When ducted properly, the HP-Series can be used as a room air conditioner to cool an
enclosed space. Using the condenser return air plenum, additional ceiling kit, and other
accessories, the HP-Series can then operate as a room air conditioner with the
condenser air isolated from the conditioned space.

PREVENTIVE MAINTENANCE
HP-Series Heat Pumps are designed to last a long time and to give maximum
performance and reliability with minimum maintenance. To prolong the life of the unit,
regular maintenance must be performed as specified below:
BLOWER MOTORS
The motors on all units have permanently lubricated bearings. No oiling is
necessary
FILTERS
A clogged filter will cause the unit to operate at greatly reduced efficiencies. We
recommend that the filter be inspected on a regular basis every six weeks or less,
depending on the environment. The evaporator filter is located behind the return air grille
and can be easily removed and cleaned. The condenser filter is located on the backside
of the unit. The filters must be washed periodically as needed by placing them in a
dishwasher or soaking them in a solution of warm water and detergent for 10 minutes.
Then rinsing them clean with hot water and shaking excess moisture from filter.
CONDENSATE PUMP
Condensate pumps come standard on all Size 60 models, and may be installed as
options on size 12, 18, 24 and 36 models. When servicing pump follow these steps;
1. Make certain that the unit is disconnected from the power source before attempting to
service or remove any component.
2. Be sure the floats move freely. Clean as necessary.
3. Remove the pump housing and check for obstructions.
4. Clean the housing with warm water and mild soap when mineral deposits are visible.
5. Check the inlet and outlet piping. Clean as necessary. Be sure there are no kinks in the
lines that would restrict flow.
GENERAL
When necessary maintenance steps outlined above are followed, the air conditioner will
provide long and reliable service. The refrigeration and electrical circuits of the system
should only be serviced by a fully qualified service technician.

THREE PHASE MONITOR
Three-Phase units are equipped with monitors for motor protection. The
TEMP-COOL Three-phase Monitor safeguards the unit against
incorrect compressor rotation, low-voltage and/or loss of power in any
one of the power legs. The monitor is installed in the control box and
is equipped with an LED for diagnosis of an improper electrical condition
(see diagrams below). When power is connected, the compressor WILL
NOT engage until the monitor start delay has timed out. If the thermostat
does not power up, an electrical condition may need to be addressed.
Remove the control box cover and observe the LED on the phase
monitor. The LED signals the following:
GREEN-BLINKING - Start delay, 120 sec.
GREEN - Proper Operation
RED/GREEN-BLINKING - signals reverse phase rotation. Switch any
two of the power leads for the unit, NOT THE MONITOR LEADS, and
re-start.
RED-BLINKING - signals improper voltage and/or phase loss. Correct
the power problem, then re-start the unit.
In the event of a power interruption, the unit will re-set to a start-up
condition. The Phase Monitor will not allow the unit to start until power
is corrected.
