Horizontal/Side Discharge Condensing Units
OPERATING INSTRUCTIONS
Air conditioners are designed to provide comfort
cooling at outside temperatures above 65°F
(18°C) but less than 109°F (43°C). Operating the
air conditioner outside of this temperature range
may cause unit failure and will void the warranty.
If you have need for cooling at lower outdoor
temperatures a “low ambient co
ntrol
” can be field
installed. Contact your local contractor or call the
factory.
TO OPERATE:
NOTE:
The thermostat operation may vary
by type and model used. Please consult the
operating manual that was provided with
the thermostat. The instructions below are
generalized for most standard thermostat
models.
1. Set the switch on your wall thermostat to the
‘cool’ position.
2. Set the desired temperature (between 63-86°F
or 17-30°C) you want to maintain by moving the
temperature setting on your thermostat. If the
room is warmer than the setting, the unit will
turn on and begin to blow cool air after a few
minutes. A warm, humid room or building may
take several hours of continuous operation to
cool to the thermostat set point the first time.
Once the set temperature is reached the unit
will cycle on and off.
3. Set the ‘Fan’ switch on the thermostat to ‘auto’
if you want the fan to run only when cooling
is needed or to ‘on’ if you want continuous
air circulation. The ‘on’ setting of the fan
generally provides better temperature control by
eliminating stagnant air.
NOTE:
A properly installed and sized unit will
not cycle more than 10 times per hour. If you
notice more frequent starts call your service
contractor.
4. For energy conservation reasons, you may want
to set your thermostat at a higher temperature
when you are away. Do not raise the
temperature setting by more than 5 degrees.
Changing the temperature by more than 5
degrees or shutting the unit ‘off’ can actually
cost more than leaving the setting at a constant
temperature.
IMPORTANT
Wait at least 3 minutes after turning your air
conditioner off before trying to restart it. This
gives the unit the time needed to stabilize
before restarting. Failure to do so may cause
unit damage and failure.
MAINTENANCE:
Only simple periodic maintenance is required:
1.
Change or clean the indoor unit air fil
t
er
monthly
or more frequently if unusual conditions
are
encountered. If you have a disposable type,
throw the old one away and install a fresh one
of the same size and type. If your unit has a
washable type then vacuum and wash with
soap and water. Flush thoroughly and dry
before re-installing.
2.
Keep the coil in the outdoor unit clean.
Periodically flush the coil thoroughly with a
garden hose. Clean away all foreign materials
such as dust, leaves, grass clippings, papers,
etc.
IMPORTANT!
Alterations and replacement parts:
Altering the product or replacing parts
with non-authorized parts will void the
factory Warranty and may result in adverse
operational performance and/or a possible
hazardous safety condition to service
personnel and occupants. If you are in doubt
as to how to service this unit or where to find
factory replacement parts, call Heat Controller
at (517) 787-2100 for assistance.
WARNING
Turn the power off first! Serious injury or death
may result if water spray is directed at live
electrical connections or power sources.
