NOTE:
If unit
is located
in or above
a living
space
where
damage
may result from
condensate
overflow,
a field-supplied,
external
condensate
pan should
be
installed
underneath
entire
unit,
and
a secondary
condensate
line
(with
appropriate
trap)
should be run from the unit into the pan. Any condensate
in this
external
condensate
pan should
be drained
to a noticeable
place.
As an alternative
to using
an external
condensate
pan,
some
localities
may allow the running
of a separate
3/4-in.

line (with appropriate
trap) per local
code to a place where

The owner of the structure
must be
informed
that when

or
external

the
unit
requires
servicing
or water

MAINTENANCE
To ensure
optimum
performance
and
to minimize
possible
equipment
problems,
periodic
maintenance
must be performed
on
this equipment.
Consult
your
dealer
on proper
frequency
of
maintenance
and the availability
of a maintenance
contract.
Proper maintenance
on this equipment
requires
certain
skills and
tools.
If you
do
not
possess
these,
obtain
qualified
dealer
assistance.
ELECTRICAL
SHOCK
HAZARD
Failure
to follow
this warning
could
result
in personal
injury or death.
Disconnect
all electrical
power
to air handler
(furnace)
and
outdoor
unit before
performing
any maintenance
or service
on
unit.
Units
may
have
more
than
1 electrical
power
supply.
Minimum
maintenance
should be performed
on the equipment
as
follows:
1. Check
and clean
or replace
air filter
each
month
or as
required.
2. Check cooling
coil, drain pan and condensate
drain at start
of each cooling
season for cleanliness.
Clean as needed.
NOTE:
Because
of possible
damage
to equipment,
or personal
injury,
maintenance
should
be performed
by qualified
persons
only.
CUT
HAZARD
Failure
to follow
this
warning
could
result
in personal
injury.
Sheet metal parts may have sharp edges or burrs.
Use care
and wear
appropriate
protective
clothing
and gloves
when
handling
parts.
A. Air Filter
An air filter is not provided
as an integral
part of this cooling
coil.
However,
a field-supplied
filter must be used upstream
of the coil
and must
be inspected
frequently.
When filter becomes
clogged
with
dust or lint,
it should
be replaced
(disposable
type)
or
cleaned
(cleanable
type).
Inspect
filter at least once each month
and replace or clean at least twice a year (more often if necessary).
NOTE:
Do not operate
coil without
a filter in place in return-air
duct. Always
replace
filter with same size and type filter.
B. Condensate
Pan and Drain
Check
drain pan and condensate
drain at the same time cooling
coil is checked.
Clean drain pan and condensate
drain thoroughly.
Flush pan and drain tube with clear water. If drain tube or trap is
restricted,
clean with high-pressure
water. If this does not work,
try a plumber's
snake or similar probe device.
C. Cleaning
Coil
To gain access
to coil. it may be necessary
to cut a window
in
ductwork.
After
cutting
out section
of ductwork
and cleaning
coil, cover
opening
with new, evenly
cut piece of sheet
metal and fasten in
place with sheet metal screws.
Coil is easily cleaned
when
dry. Therefore,
check and clean coil
before
each
cooling
season.
Inspect
coil
periodically
during
cooling
season.
If coil
is coated
with
dirt or lint, clean with
a
vacuum
using
soft brush
attachment.
BE CAREFUL
NOT
TO
BEND
COIL FINS. If coil is coated with oil or grease,
disconnect
and remove
coil from
ductwork.
Clean
coil with
mild detergent
and water solution.
Rinse with clear water.
