Homeowner Information - Allied Air 4SHP13 Series Installation And Maintenance Instructions Manual

HOMEOWNER INFORMATION

In order to ensure peak performance, your system must be
properly maintained. Clogged filters and blocked airflow
prevent your unit from operating at its most efficient level.
WARNING
Turn all electric power to unit OFF at disconnect
switch(es) before performing any maintenance
operations on system. Unit may have multiple power
supplies. Electrical shock could cause personal injury
or death.
Ask your dealer to show you where the indoor unit's filter
is located. It will be either at the indoor unit (installed
internal or external to the cabinet) or behind a return air
grille in the wall or ceiling. Check the filter monthly and
clean or replace it as needed.
Disposable filters should be replaced with a filter of the
same type and size. If you are unsure of the filter you
need for your system, contact your dealer.
Many indoor units are equipped with reusable foam filters.
These filters can be cleaned with a mild soap and water
solution. Rinse the filter thoroughly and let dry completely
before returning to unit or grille.
The filter and all access panels must be in place any
time the unit is in operation.
Some systems are equipped with an electronic air cleaner,
designed to remove the majority of airborne particles from
the air passing through the cleaner. If your system
includes an electronic air cleaner, ask your dealer for
maintenance instructions.
Inspect and clean indoor indoor coil. The indoor
evaporator coil is equipped with a drain pan to collect
condensate formaed as the system removes humidity
from the inside air. Have your dealer show you the location
of the drain line and how to check for obstructions. This
also applies to an auxiliary drain, if one is installed.
Inspect and clean outdoor coil:
Make sure no obstructions restrict airflow to the outdoor
unit. Leaves, trash, or shrubs crowding the unit can cause
it to work harder and use more energy. Keep shrubbery
trimmed away from the unit and periodically check for
debris which collects around the unit.

The outdoor coil may require frequent cleaning, depending
on environmental conditions. Clean the outdoor coil with
an unpressurized water hose to remove surface
contaminants and debris. It may be necessary to flush
the outdoor coil more frequently if it is exposed to
substances which are corrosive or which block airflow
across the coil (such as pet irome, cottonwood seeds,
etc...).
Heat Pump Operation
Heat pump untis have several characteristics you should be
aware of:
Heat pumps satisfy heating demand by delivering large
amounts of warm air into the living space. This is quite
different from gas-fired, oil-fired, or electric furnaces which
deliver lower volumes of considerably hotter air to heat
the space.
Do not be alarmed if you notice frost on the outdoor coil
in the winter months. Frost develops on the outdoor coil
during the heating cycle when temperatures are below
45° F. An electronic control activates a defrost cycle
lasting 5 to 15 minutes at preset intervals to clear the
outdoor coil of the frost. A shift in sound type does occur
during the defrost mode.
During the defrost cycle, you may notice steam rising from
the unit. This is a normal occurrence. The thermostat
may engage auxiliary heat during the defrost cycle to
satisby a heating demand. The unit will return to normal
operation at the conclusion of the defrost cycle.
In case of extended power outage....
If the outdoor temperature is belwo 50° F and power to the
outdoor unit has been interrupted for 6 hours or longer,
observe the following when restoring power to the heat pump
system.
Set th e room thermostat selector to the "Emergency Heat"
setting to obtain temporary heat for a minimum of 6 hours.
This will allow system refrigerant pressures a nd
temperatures enough time to return to a stabilized
condition.
In the Emergency Heat mode, all heating demand is
satisfied by auxiliary heat; heat pump operation is locked
out. After a 6-hour "warmup" period, the thermostat can
then be switched to the "Heat" setting and normal heat
operation may resume.
