STANDARD FEATURES
CABINET
The 2OACH 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 2OACH 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 continuously
at one of six levels of fan speed.
CONDENSATE TANK/PUMP
2OACH 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 2OACH60 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 2OACH 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 2OACH 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 2OACH 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 2OACH 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 2OACH 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 2OACH 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 2OACH can then operate as a room air conditioner with the
condenser air isolated from the conditioned space.
