Horizontal/Side Discharge Condensing Units

GENERAL PRODUCT INFORMATION

UNPACKING AND INSPECTION:

The condensing unit is shipped completely 

assembled and in it’s own package. All goods are 

inspected at the factory and released to the freight 

company in good condition. When received at the 

site, a visual inspection of all packages should be 

made immediately. Any evidence of rough handling 

or apparent damage should be noted on the 

delivery receipt and the material inspected in the 

presence of the carrier’s representative. If damage 

freight company.

COOLING OPERATION 

TEMPERATURE LIMITS:

Heat Controller Condensing units are designed 

to operate in cooling at outside temperatures 

between 65°F (18°C) and 109°F (43°C). If 

the condensing unit will be used to cool at 

temperatures below 65°F (18°C), a low ambient 

65°F (18°C) without low ambient control will void 

the warranty.

INDOOR UNIT USE 

AND SYSTEM EFFICIENCY:

Heat Controller condensing units are designed to 

be compatible with most major brands of domestic 

evaporator coils/air handlers. Imported ductless air 

handlers maybe used but often do not include an 

expansion device. A properly sized thermostatic 

expansion valve is recommended. Consult AHRI’s 

THERMOSTAT AND INDOOR 

FAN TIME DELAY:

All indoor units should include a fan time delay. 

This may be accomplished by using a digital wall 

thermostat or installation of a 60 second fan time 

air handler. 

Most brands of electronic thermostats include a 

responsibility of the installer. Proper temperature 

control and unit operation depends on proper 

thermostat selection and location. Refer to the 

thermostat manufacturer’s installation instructions 

to avoid outside walls, locations where the sun 

may shine directly on the thermostat, and locations 

where the air from supply registers or unit outlets 

blow on the thermostat. Also avoid locations where 

the thermostat could be jarred by a closing door or 

not provided by the factory, therefore a locally 

any particulates or moisture that may be 

present in the system.  Installations without an
