HEATING
1. Outdoor air enters the heat pump.
2. The cold, heat=transfer section (outdoor coil)
extracts the heat from the air as the refrigerant
evaporates from a liquid to a cold gas.
3. The refrigerant, compressed to a hot gas by
the heat pump, carries the heat to the heattransfer section (indoor coil).
4. The hot, heat=transfer section (indoor coil)
releases the heat as the refrigerant condenses
from a gas to a liquid.
5. The blower circulates the heat throughout the
home via the supply duct.
6. The refrigerant returns to the outdoor coil and
evaporates once again to absorb more heat.
SUMMER
COOLING
1. Indoor air enters the return air duct.
2. The cold, heat=transfer section (indoor coil)
extracts the heat from the air as the refrigerant
evaporates from a liquid to a cold gas.
3. The refrigerant, drawn to the heat pump and
compressed to a hot gas, carries the heat
outdoors.
4. The hot, heat=transfer section (outdoor coil)
releases the heat as the refrigerant condenses
from a gas to a liquid.
5. The heat pump (outdoor fan) discharges the
heat to the outside air.
6. The refrigerant returns to the indoor coil and
evaporates once again to absorb more heat.
It is the sole responsibility of the homeowner to
make certain that heat pump has been correctly
set up and adjusted to operate properly.
2. Resetting circuit breakers or other switches.
The Manufacturer warrants the heat pump to be
free from defects in material orworkmanship for a
period of one year. We will not be responsible for
any costs found necessary to correct problems
due to improper setup, improper installation,
adjustments, improper operating procedure on
the part of the user, etc.
To avoid misunderstandings
at a later date,
carefully review these responsibilities with your
dealer or service company.
Some specific examples of service calls which
are not included in the limited warranty are:
1. Correcting wiring problems in the electrical
circuit supplying the heat pump.
3. Adjusting or calibrating of thermostat.
The heat pump system will heat and cool your
home and save your energy dollars.
During the summer, a heat pump cools a house
by absorbing heat from within the house and
exhausting it outdoors. During the winter, a heat
pump heats a house by absorbing heat outdoors
and exhausting it indoors. This is an efficient
heating means because you pay for "moving"
heat from outdoors to indoors, but do not pay
to generate the heat.

Defrost _ During cold weather heating operation,
the outdoor unit will develop a coating of snow
and ice on the heat transfer coil. This is normal
and the unit will periodically defrost itself. During
the defrost cycle, the outdoor fan will stop, while
the compressor continues to run and heat the
outdoor coil, causing the snow and ice to melt.
During defrost, there may be some steam rise
from the outdoor unit as the warm coil causes
some melted frost to evaporate.

Heat = Some thermostats will
include a system switch position termed EM HT
or AUX HT, etc. This is a back=up heating mode
available if supplemental electrical resistance
heat is installed. With the system switch set to
EM HT, etc., the compressor and outdoor fan
will be locked offand supplemental heat (electric
resistance heating) will be used as a source of
heat. Sustained use of electric resistance heat in
place of the heat pump will result in an increase
in electric utility costs.

DEFROST CONTROL
AND TESTING
BOARD OPERATION
1. Terminals "R"-"C" must have 24+V present
between them in order for the time delay and
defrost sequences to be operational.
2. Jumper the "T2"-"DFT" test pins. This will
indicate to the board that the defrost T-stat
is closed(if the compressor
is running).
Defrost %stat is closed at 32 ° or below and
is open at 68 ° or above. But it's state is
unknown if the temperature is between 32°F
and 68°R The defrost thermostat tells the
board whether a defrost cycle needs to be
started or terminated. With the DFT closed
the unit will run for 30/60/90 minutes in heat
mode and then defrost the outdoor coil. The
defrost will turn offthe outdoor fan, turn on the
compressor and raise the coil temperature to
68°R This will open the DFT and terminate
the defrost. If the DFT does not open the
defrost will end after 10 minutes.
3. Defrost board speed=up. With compressor
running in heat mode, next jump the "Test"
pin to "C" on terminal strip. This will initiate
a defrost test in 5, 10 or 15 seconds (This
is determined by the 30, 60 or 90 minute
defrost pin settings. The factory setting will
be 30 minutes). Note that this will bypass the
compressor off delay when the unit goes into
defrost test and if left in defrost test, the delay
will be bypassed when the test is terminated
by the processor. If the jumper is removed
before the test is over the processor will
perform the remainder of a normal defrost.
See step 2 above.
4. Remove the jumpers.
To set the cycle timer, place the timing pin on
the defrost control board to the desired time
interval post.
Note: All units are shipped from the factory with
the default time setting of 30 minutes.
Field Installed Electric Heat m These Single
Package Heat Pumps are designed to allow
optional electric heat to be field installed as
required bythe building's particular heating load.
The options available for each unit are shown in
the heater kit installation instructions. As noted
in the instructions, a field installed circuit breaker
kit is available as a means of electrical disconnect for the unit.
Install the heater kits as directed bythe installation
instructions that come as part of the heater kit.
Follow all cautions and warnings as directed.
Note: The delay/no-delay
pin concerns
compressor operation during defrosts.The default
setting is delay. Reciprocating
compressors
should only use this setting in conjunction with
an approved hard start kit. Scroll compressors
that have noise issueswhile going into or coming
out of defrost should use this 30 second delay to
reduce the defrost noise.To switch from no-delay
to delay remove the pin from the "no-delay" pin
location and shift it to the "delay" pin location.
Speed up changes:
Manually initiating a defrost will cause the
compressor to run continuallywhen entering
