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.
