STANDARD FEATURES
CABINET
The 2OACH1211 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 2OACH1211 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. In the event of a power outage, all thermostat settings are
saved, and the unit will re-start automatically.
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 continu-
ously at one of six levels of fan speed.
CONDENSATE TANK/PUMP
The 2OACH1211 unit comes equipped with a means for handling the condensate
generated during the cooling/heating process. The tank can be easily removed from
the unit and emptied as needed.
An optional automatic condensate pump (UPK-115) is available and can be factory
installed . 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 2OACH1211 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 2OACH1211 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 fault setting “CON”. The compressor
can then be re-started, once the condensing pressure has equalized, by depressing
the “RESET” button.
POWER CORDS
All 2OACH1211 units come standard with a power cord for a convenient connection. It
is equipped with LCDI for added safety features.

APPLICATIONS
COOLING MODE—SPOT COOLER
The 2OACH1211 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 2OACH1211 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 2OACH1211 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 2OACH1211 can then operate as a room air conditioner
with the condenser air isolated from the conditioned space.

PREVENTIVE MAINTENANCE
2OACH1211 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
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. Remove pump assembly.
3. Be sure the floats move freely. Clean as necessary.
4. Remove the pump housing and check for obstructions.
5. Clean the reservoir with warm water and mild soap when mineral deposits are
visible.
6. Check the inlet and outlet piping. Clean as necessary. Be sure there are no kinks
in the lines that would restrict flow.
7. Reinstall pump assembly.
GENERAL
When necessary maintenance steps outlined above are followed, the air conditioner
