Heat Controller 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
is found a claim should be immediately file with the
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
control must be field installed. Operation below
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
directory of certified products for indoor matches.
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
delay designed to work with your specific furnace/
air handler.
Most brands of electronic thermostats include a
fan delay. Properly specified thermostats are the
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
for specified recommendations. Good practice is
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
high traffic area.
WARNING: An in-line filter drier is required
when the unit is installed. The filter drier is
not provided by the factory, therefore a locally
purchased filter drier must be used to remove
any particulates or moisture that may be
present in the system. Installations without an
in-line filter drier may void the warranty.
