OPERATION . . . The Heat Pump system is designed to run more of the
time than other systems. This does not mean that is is wasting power.
On the contrary, it conserves power by operating on a smoother
temperature cycle. It also means your temperature stays a little more
constant, and your home a little more comfortable. In many cases when
the outdoor temperature drops to the 20's or 30's or below, the unit runs
constantly. Don't worry, this is normal and it won't make your electric
bill go out of sight.
At the same time this happens, the indoor
temperature may drop one or two degrees below the point where your
thermostat is set. The system could be designed so this would not
happen, but if so it would not be as efficient. If the lowered temperature
is uncomfortable, you may want to increase the thermostat setting for a
while. When the temperature comes back up outside, the effect will go
away again.
NIGHT SET-BACK . . . Currently, it is quite common to reduce the
temperature setting on a heating system at night and then return it to
normal in the morning. This can be done either manually or with a
special thermostat. However, it is not recommended that a Heat Pump
system be set-back. It appears from what is now known, that night set-
back of a Heat Pump actually costs you money rather than saving it.
DEFROST . . . The normal heating operation of a Heat Pump results in
a coating of frost accumulating on the outdoor unit. Periodically, the unit
will automatically defrost itself. When the unit goes into defrost a
"whooshing" sound is audible if you happen to be near the unit. (This
same sound can be heard when the unit shuts off during heating
operation.) The sound is normal and should be no cause for alarm. It is
also normal for steam to come off the outdoor coil during the defrost.
Defrost is completely automatic and is controlled by sensors in the
outdoor unit.
QUESTIONS . . . If you still have questions or doubts about the
performances of operation of your Heat Pump system, contact Chas
Roberts Air Conditioning. They are experts in heating and cooling and
will be happy to assist you.
UNDER NO CIRCUMSTANCES SHOULD THE THERMOSTAT BE
TURNED OFF AND THEN IMMEDIATELY TURNED ON AGAIN. THIS
QUICK CYCLING CAN AND WILL BURN OUT CONTROLS IN
STARTING CIRCUITS AND ALSO IN THE COMPRESSOR. IF THE
THERMOSTAT IS TURNED OFF, DO NOT TURN BACK ON FOR AT
LEAST THREE (3) MINUTES.
OPERATING THE THERMOSTAT:
HEATING CYCLE:
Switch the system lever to HEAT. Then set the Temperature Selection
Lever to the desired temperature.
COOLING CYCLE:
Switch the system lever to COOL.
FAN CONTROL:
Your thermostat has a Fan Selection Switch which will allow you to run
the fan continuously or cycle it automatically with the heating or cooling
system. Switch the lever to ON for continuous operation and to AUTO
for automatic cycling. For maximum comfort satisfaction, constant fan
operation throughout the year is recommended.

SERVICE HINTS AND POINTS TO CHECK IF YOUR UNIT BECOMES
INOPERATIVE:
1. CHECK FUSES
Use only Fusetron or Fusestat type fuses. On cartridge types, some
type of fuse tester should be used. These fuses might be found in the
optional disconnect attached to the unit or wall adjacent to the outdoor
unit. They also might be found in the main electric panel inside the
building.
2. DIRTY FILTERS
When operating on the cooling cycle and the filters are dirty, your unit
may short cycle (go off and on) and frost may form on the indoor coil as
well as the large line between the outdoor unit and the coil installed in
the indoor Air Handler.
When operating on the heating cycle, and the filters are dirty, the
compressor will be running at an abnormally high temperature. This can
cause the compressor to shut-off.
Clean or replace the filters if they are the disposable type. The filter can
be found contained in the Air Handler filter rack or box adjacent to or
under the Air Handler or in a return air filter grille.
3. INDOOR EVAPORATOR COIL COVERED WITH ICE OR NO
BLOWER ACTION
Check for broken blower belt or defective blower motor.
4. CLOGGED COIL IN OUTDOOR UNIT (SUMMER)
Grass cutting, leaves, dirt and dust, lint from clothes dryer, fall-off from
trees, can be drawn into the coil by movement of the air. A clogged
condenser coil will lower the efficiency of your unit and could cause
damage to the condenser. Damage of this type is not covered by the
Warranty. Use a brush to remove debris from the coil.
