Short Cycle Compressor Delay
The automatic ignition control has a built-in feature that
prevents damage to the compressor in short cycling
situations. In the event of intermittent power losses or
intermittent thermostat operation, the ignition control will delay
output to the compressor contactor for three minutes from the
time power is restored. (Compressor is off a total of three
minutes). The diagnostic LED will flash six (6) times to indicate
the compressor contactor output is being delayed.
NOTE: Some electronic thermostats also have a built-in compressor
short cycle timer that may be longer than the three minute delay
given above. If you are using an electronic thermostat and the
compressor has not started after three minutes, wait an additional
five minutes to allow the thermostat to complete its short cycle
delay time.
High Pressure Switch/Loss of Charge Switch
(Two-Stage Models ONLY)
Some models include a high pressure cutout switch and/or a
loss of charge cutout switch. The high pressure cutout switch
protects the refrigeration system from excessive operating
pressures. The loss of charge cutout switch protects the
refrigeration system from very low operating pressures due
to a loss of refrigerant. Compressor operation will be disabled
if either of these devices opens. If either device opens, the
diagnostic red LED will flash (9) times to indicate that a
refrigeration system pressure switch is open.
MAINTENANCE
Have the gas heating section of the unit checked at least
once a year before the heating season begins, to be sure that
the combustion air inlet and flue outlet hoods are not blocked
by debris, which would prevent adequate combustion air and
a properly operating vent system.

LEANING
A return air filter is not supplied with this unit; however, there
must be a means of filtering all of the return air. The filter(s)
may be located in the return air duct(s), or return air filter
grille(s). Consult with your installing dealer for the actual
location of the return air filter(s) for your unit.
Dirty filters are the most common cause of inadequate heating
or cooling performance. Filter inspection should be made at
least every two months; more often if necessary because of
local conditions and usage.
Dirty throwaway filters should be discarded and replaced with
a new, clean filter. Dirty permanent filters should be washed
with water, thoroughly dried and sprayed with a filter adhesive
before being reinstalled. (Filter adhesives may be found at
many hardware stores.) Permanent filters should last several
years. However, should one become torn or uncleanable, it
should be replaced.

Use a fine grade automotive wax on the cabinet finish to
maintain the finish’s original high luster. This is especially
important in installations with extended periods of direct
sunlight.

The coil with the outside air flowing over it should be inspected
annually and cleaned as frequently as necessary to keep the

A drop in the flame current can be caused by a nearly invisible
coating on the flame sensor. This coating, created by the fuel
or combustion air supply, can be removed by carefully cleaning
the flame sensor with steel wool.
NOTE: After cleaning, the microamp signal should be stable and in
the range of 4 - 6 microamps DC.

1. Shut off electric power and gas supply to the unit.
2. Remove burner assembly by disconnecting the gas line
and removing the manifold bracket from the partition panel.
3. Remove the flue from the induced draft blower and the
collector box cover from the partition panel.
4. The primary heat exchanger tubes can be cleaned using
a round wire brush attached to a length of high grade
stainless steel cable, such as drain cleanout cable. Attach
a variable speed reversible drill to the other end of the
spring cable. Slowly rotate the cable with the drill and insert
it into one of the primary heat exchanger tubes. While
reversing the drill, work the cable in and out several times
to obtain sufficient cleaning. Use a large cable for the large
tube, and then repeat the operation with a small cable for
the smaller tube. Repeat for each tube.
5. When all heat exchanger tubes have been cleaned,
replace the parts in the reverse order in which they were
removed.
