Unit installation

3
1. Always install and keep filters clean. Check filters every 10 days
to 2 weeks. Clean or replace if necessary. The factory-installed
filter is located behind the center front access panel.
TO CHANGE SYSTEM FILTER:
A. Turn the power to the unit off at the unit disconnect. The
disconnect is located on the front of the H Series unit behind
a small access door.
B. Remove the front center access door from the unit.
C. Remove and replace the filters with the type and size
indicated in the table below.
D. Replace the access door and turn on the power to the unit.
NOTE: If your system has a filter grille installed in the return air
opening, the unit filter should have been discarded during
installation.
The filter installed into the return air grille assembly should be
replaced with the same size and type provided with the grille.
If your system is equipped with a fresh air intake, the filter for the
fresh air assembly is accessed through the front center panel. The
filter is a permanent washable type.
TO CLEAN FRESH AIR
INTAKE FILTER:
A. Follow steps A and B at left “TO
CHANGE SYSTEM FILTER”.
B. Gently pull out the filter from the
bottom.
C. Wash the filter with water.
D. Reinstall the filter, by sliding it into
the retaining rail.
E. Replace the access door and turn
the power on to the unit.
2. Keep the outdoor coil clean. Wash it down with a garden hose if
necessary. BE SURE THE UNIT DISCONNECT IS IN THE
“OFF” POSITION AND THAT ALL ELECTRICAL POWER TO
THE UNIT IS TURNED OFF BEFORE CLEANING THE
SYSTEM.
Remove any loose grass, leaves, papers, etc., from the area
around the condenser coil. These could reduce the air
supply through the coil and reduce the amount of cooling
capacity.
3. Since the heat pump is located outdoors, it is exposed to all
weather elements. Treat it with a good automobile paste wax
twice a year (in the spring and fall).
Check with your contractor if you have any questions regarding
the maintenance or operation of your unit.
Set the thermostat to either HEAT or COOL as desired. Set the
desired temperature on your thermostat dial and set the fan
switch to “ON” (for continuous air circulation) or to “AUTOMATIC”
(for air circulation only when the air conditioning system is
operating). If you desire to vary the thermostat temperature
setting during the day for energy conservation (for example, while
you are at work) do not vary the setting more than 5°F from your
normal temperature setting. Changing the temperature more than
5°F or turning the thermostat off for periods less than 12 hours
can actually cost you more in energy consumption than keeping
the temperature constant. You should also consider indoor plants
and pets when varying the temperature from the normal comfort
level.
IMPORTANT: Wait at least three (3) minutes after turning the
heat pump off before trying to restart. If an attempt is made to
start the compressor before the refrigerant pressures are
equalized, the compressor motor may trip on its overload. An
additional waiting period will be required before restarting.
