PERFORMING
ROUTINE
MAINTENANCE
With
the proper
maintenance
and care, your heat pump will operate
economically
and dependably.
Maintenance
can be accomplished
easily by
referring
to the following
directions.
However,
before
performing
maintenance,
consider
these
important
safety precautions:
Z_X WARNING:
Disconnect
all electrical power to the indoor air handler or furnace before removing access panels to
perform any maintenance. Disconnect power to both the indoor and outdoor units. Note: There may be more than I electrical
disconnect switch. Electrical shock can cause serious injury or death.
Z_x
CAUTION:
Although special care has been taken to minimize sharp edges in the construction
of your unit, to avoid
injury be extremely careful when handling parts or reaching into the unit.
PROCEDURE
1--CHECK
THE AIR FILTER
A dirty air filter will cause
excessive
strain on the compressor
and blower
motor.
This can cause the components
to overheat
and automatically
shut down.
In the worst case, the components
will fail and need to be replaced.
To avoid inefficient
or failed operation
of your unit, CHECK
THE
FILTER(S)
EVERY
3 TO 4 WEEKS.
Replace
filter(s)
when necessary,
or clean the filter(s)
if you have
the reusable
type.
Disposable
filters
should be replaced
by similar,
new filters of the same dimensions.
Reusable,
permanent
filters
should
be washed
in a solution
of cold water
and mild detergent,
then rinsed
and thoroughly
dried.
THE FILTER
MUST
BE COMPLETELY
DRY BEFORE
BEING
REINSTALLED.
To avoid
prolonged
shutdown
of your unit while
a filter
is drying,
you
should have an extra filter on hand. This allows you to rotate between
the two with minimal
downtime
for your comfort
system.
Extra filters may
be purchased
from your dealer.

The filters(s)
and filter rack fbr a packaged
system
are supplied
and installed
by the contractor
or dealer. Typically,
the filter(s)
and rack are located
in the return-air
duct at the outdoor
unit or behind
the return-air
grille(s).
Have your
dealer
show you
the location
of your
filter(s)
and the
procedures
for removal
and replacement.
If your system
includes
a high efficiency
or electronic
air cleaner,
refer to air cleaner
User's
Mmmal
for proper
filter
cleaning
or replacement.
PROCEDURE
2--OUTDOOR
COIL
If" grass clippings,
leaves,
shrubbery,
and debris m'e kept away from the unit, minimal
care should be sufficient
to keep the system
functioning
properly.
However,
if the outdoor
coil becomes
dirty, use a vacuum
cleaner
or shop vac with soft brush
attachment
to clean the exterior
surface.
Vacuum
coil surface
using
an up and down
motion.
Be careful
not to bend
or damage
fins.
If dirt is deep in the coil, contact
your dealer
for service.
Do not attempt
this yourself.
PROCEDURE
3--OUTDOOR
COIL--SEA
COAST
If your unit is located
near the ocean,
special
maintenance
is required.
Ocean mist_reeze
carries salt, which is corrosive
to most metals.
Although
your new unit is made out of galvanized
metal and is protected
by top-grade
paint, you should take the precaution
of additional
maintenance
which
consists
of periodically
washing
the unit. By washing
all exposed
surfaces
and coil, you will be adding
additional
life to your unit. Please
consult
your installing
contractor
for proper
intervals@roeedures
for your geographic
area or seswice contact.
PROCEDURE
4--UNIT
SUPPORT
Your packaged
heat pump unit should be maintained
at a level position.
If its support
should shift or settle so that the unit is no longer level, you
should
correct
the condition.
Relevel
it promptly
to assure
water
drains out of the unit. If you notice
that water
or ice collects
beneath
the unit,
arrange
for it to be drained
away from
the unit.
