All refrigerant discharged from this unit
must be recovered WITHOUT EXCEPTION.
Technicians must follow industry accepted
guidelines and all local, state, and federal
statutes for the recovery and disposal of
refrigerants. If a compressor is removed
from this unit, refrigerant circuit oil will
remain in the compressor. To avoid leakage
of compressor oil, refrigerant lines of the
compressor must be sealed after it is
removed.
To avoid equipment damage, DO NOT use
these units as a source of heating or cooling
during the construction process. Doing so
may affect the unit’s warranty. The
mechanical components and filters will
quickly become clogged with construction
dirt and debris, which may cause system
damage.
To avoid the release of refrigerant into the
atmosphere, the refrigerant circuit of this
unit must be serviced only by technicians
who meet local, state, and federal
proficiency requirements.

GENERAL DESCRIPTION
SM Series Water-to-Air Heat Pumps provide the
best combination of performance and efficiency
available. All units are performance certified to
American Heating and Refrigeration Institute
(AHRI) ISO Standard 13256-1. All SM Water-to-Air
Heat Pumps are Underwriters Laboratories (UL)
and (cUL) listed for safety. The Water-to-Air Heat
Pumps are designed to operate with entering fluid
temperature between 20°F to 90°F in the heating
mode and between 30°F to 120°F in the cooling
mode.
50° Minimum Entering Water Temperature
(EWT) for well water applications with sufficient
water flow to prevent freezing. Antifreeze
solution is required for all closed loop
applications. Cooling Tower/Boiler and
Geothermal applications should have sufficient
antifreeze solution to protect against extreme
conditions and equipment failure. Frozen water
coils are not covered under warranty. Other
equivalent methods of temperature control are
acceptable.

MOVING AND STORAGE
If the equipment is not needed for immediate
installation upon its arrival at the job site, it should
be left in its shipping carton and stored in a clean,
dry area. Units must only be stored or moved in the
normal upright position as indicated by the “UP”
arrows on each carton at all times.
For storage If unit stacking is required,
stack units as follows:
Do not stack units larger than 6 tons.
7
Vertical units less than 6 tons, no more than
two high.
6
3
Horizontals units less than 6 tons, no more
than three high.
INITIAL INSPECTION
Be certain to inspect all cartons or crates on each
unit as received at the job site before signing the
freight bill. Verify that all items have been received
and that there are no visible damages; note any
shortages or damages on all copies of the freight
bill. In the event of damage or shortage, remember
that the purchaser is responsible for filing the
necessary claims with the carrier. Concealed
damages not discovered until after removing the
units from the packaging must be reported to the
carrier within 24 hours of receipt.

Locate the unit in an indoor area that allows easy
removal of the filter and access panels, and has
enough room for service personnel to perform
maintenance or repair. Provide sufficient room to
make fluid, electrical, and duct connection(s). If
the unit is located in a confined space such as a
closet, provisions must be made for return air to
freely enter the face of unit’s air coil. On horizontal
units, allow adequate room below the unit for a
condensate drain trap and do not locate the unit
above supply piping.
These units are not approved for outdoor
installation; therefore, they must be
installed inside the structure being
conditioned. Do not locate in areas that are
subject to freezing.

Mounting Vertical Units | 27
SM Series Heat Pump
MOUNTING VERTICAL UNITS
Vertical units should be mounted level on a
vibration absorbing pad slightly larger than the
base to minimize vibration transmission to the
building structure. It is not necessary to anchor the
unit to the floor. (Figure #93).
On VT and CF Units Condensate Drain pan is
internally sloped. There is no internal P-Trap.
The Secondary drain pan prevents possible
condensate overflow or water leakage damage to
the ceiling.
The secondary drain pan is usually placed on a
plywood base isolated from the ceiling joists by
additional layers of vibration absorbing mesh. In
both cases, a 3/4”drain connected to this
secondary pan should be run to an eave at a
location that will be noticeable.
If the unit is located in a crawl space, the bottom
of the unit must be at least 4” above grade to
prevent flooding of the electrical parts due to
heavy rains.
HZ Units Condensate Drain pan is NOT
internally sloped.
Horizontal (HZ) units must be installed
pitched toward the Condensate Drain
Connection 1/8” per foot.
CONDENSATE DRAIN
VIBRATION
PAD FULL SIZE
Figure # 93
MOUNTING HORIZONTAL UNITS
While horizontal units may be installed on any level
surface strong enough to hold their weight, they
are typically suspended above a ceiling by
threaded rods. The rods are usually attached to the
unit corners by hanger bracket kits. The rods must
be securely anchored to the ceiling. Refer to the
hanging bracket assembly and installation
instructions for details.
Horizontal units installed above the ceiling
must conform to all local codes. An auxiliary
drain pan if required by code, should be at
least four inches larger than the bottom of
the heat pump.
Plumbing connected to the heat pump must not
come in direct contact with joists, trusses, walls,
etc. Some applications require an attic floor
installation of the horizontal unit. In this case the
unit should be set in a full size secondary drain pan
on top of a vibration absorbing mesh.
SM Series Heat Pump
Figure # 94
A drain line must be connected to the heat pump
and pitched away from the unit a minimum of 1/8”
per foot to allow the condensate to flow away from
the unit.
When converting unit from left-hand return
(default) to right-hand return, condensate drain
connection must be relocated. Refer to Pg#19.
This connection must be in conformance with local
plumbing codes. A trap must be installed in the
condensate line to insure free condensate flow.
HZ Heat Pump Drain Pan is not internally
sloped.
A vertical air vent is sometimes required to avoid
air pockets. The length of the trap depends on the
amount of positive or negative pressure on the
drain pan. A second trap must not be included.
6 720 220 406 (2013/1)
28 | Duct System
SM Series Heat Pump
DUCT SYSTEM
A supply air outlet collar and return air duct flange
are provided on all units to facilitate duct
connections.
Supply air duct and return air duct flanges are
shipped unfolded with unit.
Fold the duct flange outwards along the perforated
line. Refer to unit Dimensional Drawings for
physical dimensions of the collar and flange.
(Pg#90 through Pg#94)
A flexible connector is recommended for supply
and return air duct connections on metal duct
systems. All metal ducting should be insulated
with a minimum of one inch duct insulation to
avoid heat loss or gain and prevent condensate
forming during the cooling operation. Application
of the unit to uninsulated duct work is not
recommended as the unit’s performance will be
adversely affected.
Do not connect discharge ducts directly to
the blower outlet.
The factory provided air filter must be removed
when using a filter back return air grill. The factory
filter should be left in place on a free return
system.
If the unit will be installed in a new installation
which includes new duct work, the installation
should be designed using current ASHRAE
procedures for duct sizing. If the unit is to be
connected to existing duct work, a check should
be made to assure that the duct system has the
capacity to handle the air required for the unit
application. If the duct system is too small, larger
duct work should be installed. Check for existing
leaks and repair.
The duct system and all diffusers should be sized
to handle the designed air flow quietly. To
maximize sound attenuation of the unit blower, the
supply and return air plenums should be insulated.
There should be no direct straight air path thru the
return air grille into the heat pump. The return air
inlet to the heat pump must have at least
one 90 degree turn away from the space return air
grille. If air noise or excessive air flow are a
problem, the blower speed can be changed to a
lower speed to reduce air flow.
Never use flexible hoses of a smaller inside
diameter than that of the fluid connections
on the unit.
SM units are supplied with either a copper or
optional cupro-nickel condenser. Copper is
adequate for ground water that is not high in
mineral content.
Proper testing is recommended to assure the
well water quality is suitable for use with water
source equipment.
In conditions anticipating moderate scale
formation or in brackish water a cupro-nickel heat
exchanger is recommended.
Both the supply and discharge water lines will
sweat if subjected to low water temperature.
These lines should be insulated to prevent damage
from condensation. All manual flow valves used in
the system must be ball valves. Globe and gate
valves must not be used due to high pressure drop
and poor throttling characteristics.
Never exceed the recommended water flow
rates as serious damage or erosion of the
water-to-refrigerant heat exchanger could
occur.
Always check carefully for water leaks and repair
appropriately. Units are equipped with female pipe
thread fittings. Consult Unit Dimensional
Drawings. (Pg#90 through Pg#94)
Teflon tape sealer should be used when
connecting water piping connections to the units
to insure against leaks and possible heat
exchanger fouling.
Do not overtighten the connections.
Flexible hoses should be used between the unit
and the rigid system to avoid possible vibration.
Ball valves should be installed in the supply and
return lines for unit isolation and unit water flow
balancing.
PIPING
Supply and return piping must be as large as the
unit connections on the heat pump (larger on long
runs).

The UPM Board includes the following features:
• ANTI-SHORT CYCLE TIMER: 5 minute delay on
break timer to prevent compressor short cycling.
•
RANDOM START: Each controller has an unique
random start delay ranging from 270 to 300 seconds
on initial power up to reduce the chance of multiple
unit simultaneously starting at the same time after
power up or after a power interruption, thus
avoiding creating large electrical spike.
•
LOW PRESSURE BYPASS TIMER: If the
compressor is running and the low pressure switch
opens, the controller will keep the compressor ON
for 120 seconds. After 2 minutes if the low pressure
switch remains open, the controllers will shut down
the compressor and enter a soft lockout. The
compressor will not be energized until the low
pressure switch closes and the anti-short cycle time
delay expires. If the low pressure switch opens 2-4
times in 1 hour, the unit will enter a hard lockout. In
order to exit hard lockout power to the unit would
need to be reset.

refrigerant temperature with the sensor
mounted close to the evaporator between the
thermal expansion valve and evaporator coil as
shown in figure 5. If temperature drops below
or remains at the freeze limit trip for 30
seconds, the controller will shut the

selected the alarm output will be pulsed. The
fault output will depend on the dip switch
setting for "ALARM". If it is set to "CONST", a
constant signal will be produced to indicate a

inspection to determine the type of fault. If it is
set to "PULSE", a pulse signal is produced and
a fault code is detected by a remote device
indicating the fault. See L.E.D Fault Indication
below for blink code explanation. The remote
device must have a malfunction detection
capability when the UPM board is set to

setting for Lockout dip switch) before 60 minutes,
the unit will go into a hard lockout and requires a
manual lockout reset. A single condensate overflow
fault will cause the unit to go into a hard lockout
immediately, and will require a manual lockout
reset.
•
LOCKOUT RESET: A hard lockout can be reset
by turning the unit thermostat off and then

Just above the connector block is a single red LED
labeled CFM that will blink intermittently when the
unit is running and may flicker when the unit is off.
This LED indicates the air delivery of the blower at
any given time. Each blink of the LED represent
approximately 100 CFM of air delivery so if the LED
blinks 12 times, pauses, blinks 12 times, etc. the
blower is delivering approximately 1200 CFM.
CFM LED indication is an approximation. Utilize
conventional Test and Balance equipment for
accurate airflow measurement.
To the right of the thermostat connection block is
a green LED labeled dehumidify. Just above and to
the right of the thermostat connection block are
two banks of DIP switches labeled ADJ and CFM.
The ADJ bank DIP switches are labeled NORM, (+),
(-), Test and HGHR position from the factory,
however, airflow can be increased (+) or
decreased (-) by 15% from the pre-programmed
setting by relocating the DIP switch in this section.
The TEST position is used to verify proper motor
operation. If a motor problem is suspected, move
the ADJ DIP switch to the TEST position and
energize G on the thermostat connection block. If
the motor ramps up to 100% power, then the
motor itself is functioning normally. Always
remember to replace the DIP switch to NORM, (+)
or (-) after testing and reset the unit thermostat to
restore normal operation.
HGRH switch is used to select operating mode
between units equipped with:
1. Re-heat coils
2. Cool to dehumidify
6 720 220 406 (2013/1)

SM Series Heat Pump
When the switch is set for Hot gas re-heat -" YES"
the unit will energize the H output on P13 when
sensing a 24 VAC input on the TB01-H. This will in
terms activate the re-heat coil for active dehumidification.
When the switch is set to Hot gas re-heat - "NO".
the unit will disable the H terminal on P13 at all
times, when sensing a 24VAC signal on TB01-H the
unit will run the blower motor at a lower CFM in
order to have a passive dehumidification while
cooling the space.
Do not set the ADJ DIP switch to the (-)
setting when electric heaters are installed.
Doing so may cause the heaters to cycle on
their thermal overload switches, potentially
shortening the life of the switches.
The other DIP switch bank is used to select the
proper program in the ECM motor for the unit.
Always disconnect power before changing
jumper positions on the interface board and
reset the unit afterward.
To the left of the red and green status LED’s is a
row of 1/4” male quick connects. These are used
to pass thermostat inputs on to the rest of the
control circuit. Remember to always turn off unit
power at the circuit breaker before attaching or
disconnecting any wiring from these connections
to avoid accidental short circuits that can damage
unit control components.

SM Series Heat Pump
OPTIONS
Number of factory installed options are available
on SM Series of Heat Pumps. The following details
purpose, function and components of each option.
Hot Gas Reheat (HGRH)
Hot gas reheat is an active dehumidification option
available on the SM series that cools and
dehumidifies return air, and then reheats it back to
approximately entering dry bulb temperature using
waste compressor heat. In this way, a unit with Hot
Gas Reheat can efficiently remove humidity from
the return air without altering the sensible
temperature of the space.
Hot Gas Reheat (HGRH) Option is not available
on SM024 model.
The reheat option consists of a refrigerant to air
heat exchanger (reheat coil) mounted down
stream of the evaporator coil and a refrigerant
diverting valve. When there is a signal for
dehumidification AND the sensible space
temperature is satisfied, the unit will operate in
reheat mode. In reheat mode the heat pump will
operate at full load cooling and will divert
discharge gas from the compressor to the reheat
coil, effectively cooling and dehumidifying the air
and then reheating it back to a temperature close
to the entering dry bulb temperature. If there is a
call for sensible cooling while the unit is operating

in the reheat mode, then the unit will revert to
cooling until the sensible demand is satisfied.
Heat pumps with hot Gas Reheat need to be
connected to a humidistat along with a traditional
thermostat or a combination thermostat/
humidistat.
Electric Heat
Internally mounted supplemental electric heat is
available on select models of the SM series.
Electric heating elements can operate along with
reverse cycle heating as auxiliary heat or in lieu of
mechanical heating (refrigeration heating) as
emergency backup heat.
Heating elements are available in nominal kW
ranges of 5, 10, 15 and 20 - note that not all sizes
are available on all models. Internal mounted
Electric Heat is only available on top blow vertical
cabinets, end blow horizontal cabinet or on down
blow counterflow cabinets.
In cases where Electric Heat is not available in
a desired configuration but is needed, contact

Heat Recovery Package (HRP)
The heat recover package is a factory installed
option on SM series of heat pumps. The HRP can
be used to heat potable water during unit
operation using waste heat from the compressor
discharge gas. In some cases the HRP can provide
most or all of the hot water requirements for a
typical home.
The HRP consists of three major components:
• double wall, vented refrigerant to water heat
exchanger
SM Series Heat Pump
• circulating pump
• control circuit
The heat exchanger is rated for use with potable
water and is acceptable for use as a domestic
water heating device in most building codes.
The pump circulates water between the domestic
hot water tank and HRP heat exchanger in the Heat
Pump. The control circuit ensures that the HRP
only operates when there is available heat from the
compressor and when the water is within a safe
temperature range of below 140 deg F.
6 720 220 406 (2013/1)
36 | Options
SM Series Heat Pump
When the heat pump compressor operates, the
HRP will monitor the temperature of the discharge
gas from the compressor. Once discharge gas is
hot enough to provide useful heat to the domestic
water tank, the circulating pump will be enabled,
drawing water from the tank, through the HRP heat
exchanger and then depositing the heated water
back into the tank. If the water temperature
reaches 140 deg F, the circulating pump is
disabled to prevent over heating of the domestic
water. The HRP is provided with an on/off switch
in case the end user desires that the HRP be
inactivated (typically during the winter months
when space heating is most important).
If heat recovery unit is installed in an area
where freezing may occur, the unit must be
drained during winter months to prevent
heat exchanger damage. Heat exchanger
ruptures that occur due to freezing will void
the heat recovery package warranty along
with the heat pump warranty.
Sound Package
The SM series is offered with a factory installed
sound reduction package option. This option
improves the already industry leading noise levels
of the heat pump by adding a heavy duty, multi
density blanket over the compressor. The
materials in the blanket are engineered to
attenuate the most objectionable frequencies of
sound coming directly off of the compressor shell,
further reducing the operating noise of the heat
pump.
Soft Start
The SM series are available with start assist device
as factory installed option.
transformers. The adaptive technology of the
device can also extend compressor life by
providing smoother, lower current starts and by
protecting the compressor from transient low
voltage.
Constant Airflow Motor
The Constant Airflow Motor is an Electronic
Commutated Motor (ECM) that provides a
constant air flow over a wide range of external
static pressures, while optimizing the power
consumption of the motor.
This option allows the unit to have different air
flow settings depending on the mode that the unit
is operating; i.e heating, cooling, fan only, hot gas
reheat, etc.
DPS Water Flow Proving
The DPS water flow proving switch is a factory
installed option available for the SM series. The
DPS prevents compressor operation if there is
inadequate water flow through the water to
refrigerant heat exchanger in the heat pump.
The DPS operates by monitoring the water side
pressure drop across the water to refrigerant heat
exchanger. When the pressure drop between the
water in and water out lines reaches a pre-set
value, compressor operation is enabled.
Pump Relay
The factory installed pump relay can be used to
energize a supply pump or solenoid valve when
there is a call for compressor operation. This relay
can be used to switch either high or low voltage
power.
Comfort Alert Module
The Comfort Alert diagnostics module (CADM) is a
breakthrough innovation for troubleshooting heat
pump system failures. (Figure #102)
Figure # 101
This device reduces starting current for
compressors by 25 to 60%. This reduction in
starting current can eliminate or greatly reduce
"light flicker" during compressor starts and can
reduce the required size of back-up

Options | 37
By monitoring and analyzing data from the
compressor and the thermostat demand, the
module can accurately detect the cause of
electrical and system related failures without any
sensors. A flashing LED indicator communicates
the ALERT code and guides the service technician
more quickly and accurately to the root cause of a
problem.
This module does not provide safety protection!
The Comfort Alert module is a monitoring device
and cannot shut down the compressor directly.
When an abnormal system condition occurs, the
Comfort Alert module displays the appropriate
ALERT and/or TRIP LED.
The yellow ALERT LED will flash a number of times
consecutively, pause and then repeat the process.
To identify a Flash Code number, count the
number of consecutive flashes.
Every time the module powers up, the last ALERT
Flash Code that occurred prior to shut down is
displayed for one minute.

6. Before restoring the power or fuel supply to
the water heater, adjust the temperature
setting on the tank thermostat(s) to ensure
maximum utilization of the heat available from
the refrigeration system and conserve the most
energy. On tanks with both upper and lower
elements and thermostats, the lower element
should be turned down to 100° F, while the
upper element should be adjusted to 120° F.
Depending upon the specific needs of the
customer, you may need to adjust the upper
element differently. On tanks with a single
thermostat lower the thermostat setting to
120° F or the “LOW” position. After thermostat
adjustments are completed, replace access
cover and restore electrical or fuel supply to
water heater.
Initial Start-Up
Make sure all valves in heat recovery water
piping system are open. NEVER OPERATE
HR PUMP DRY.
1. Turn on the heat pump. The HR pump should
not run if the compressor is not running.
2. Turn HR switch to the “ON” position. The pump
will operate if entering water temperature to
HR is below 120° F.
3. The temperature difference between the water
entering and leaving the heat recovery should
be 5° to 15° F.
4. Allow the unit to operate for 20 to 30 minutes
to ensure it is functioning properly. The pump
should shut off when the water temperature
entering the heat recovery reaches 120°F.

40 | Sequence of Operation
SM Series Heat Pump
SEQUENCE OF OPERATION
Cooling Mode
Energizing the “O” terminal energizes the unit
reversing valve in the cooling mode. The fan motor
starts when the “G” terminal is energized. Note
that the fan motor will take 30 seconds to ramp up
to operating speed and will run at fan only rated air
fl ow as long as there is no call for compressor or
heater operation.
When the thermostat calls for first stage cooling
(Y1) the loop pump or solenoid valve if present is
energized and the first stage of compressor
capacity starts. The fan ramps up to first stage
cooling air flow in 30 seconds.
When the thermostat calls for second stage
cooling (Y2) the second stage (or full compressor
capacity) is initiated. The fan ramps up to full
cooling air flow.
Once the thermostat is satisfied, the compressor
shuts down accordingly and the fan ramps down to
either fan only mode or off over a span of 30
seconds.
Note that a fault condition initiating a lockout will
de-energize the compressor irrespective of
which stage is engaged.
Heating Mode
The first two stages of heating (Y1 & Y2) operate in
the same manner as cooling, but with the reversing
valve de-energized. On a call for auxiliary heat
(W1), the fan ramps up to auxiliary heat air fl ow
immediately and the electric heater package is
energized along with the compressor. As the
thermostat is satisfied, the heaters will shut off as
soon as W1 is de-energized, and the compressors
will remain on until the thermostat stages are
satisfied. Note that if the unit compressor lock out
for any reason at this time, the electric heaters will
continue to function normally. Once the
thermostat is satisfied, the compressor shuts
down and the fan ramps down either fan only
mode or off over a span of 30 seconds. If
thermostat has two different output points one for
Auxiliary heat and a different one for Emergency
heat the two outputs must be terminated on W1
units equipped with one stage of Electric heat.
(Figure #104)
When using a 2-cool, 3-heat thermostat W1 and
W2/EM must be connected together via a
jumper.

APPLICATION CONSIDERATIONS
pressure must always be maintained in the heat
exchanger. This can be accomplished with either
control valve or a bladder type expansion tank.
When using a single water well to supply both
domestic water and the heat pump care must be
taken to insure that the well can provide sufficient
flow for both. In well water applications a slow
closing solenoid valve must be used to prevent
water hammer. Solenoid valves should be
connected across Y1 and C1 on the interface board
for all. Make sure that the VA draw of the valve
does not exceed the contact rating of the
thermostat. (Figure #105)
Well Water Systems
Copper is adequate for ground water that is not
high in mineral content. Should your well driller
express concern regarding the quality of the well
water available or should any known hazards exist
in your area, we recommend proper testing to
assure the well water quality is suitable for use
with water source equipment. In conditions
anticipating moderate scale formation or in
brackish water a cupro-nickel heat exchanger is
recommended. In well water applications water

Cooling Tower/Boiler Systems
The cooling tower and boiler water loop
temperature is usually maintained between 50° F
to 100 ° F to assure adequate cooling and heating
performance.
In the cooling mode, heat is rejected from the unit
into the water loop. A cooling tower provides
evaporative cooling to the loop water thus
maintaining a constant supply temperature to the
unit. When utilizing open cooling towers, chemical
water treatment is mandatory to ensure the water
is free from corrosive elements. A secondary heat
exchanger (plate frame) between the unit and the

open cooling tower may also be used. It is
imperative that all air be eliminated from the
closed loop side of the heat exchanger to insure
against fouling. In the heating mode, heat is
absorbed from the water loop. A boiler can be
utilized to maintain the loop at the desired
temperature.
Water piping exposed to extreme low
ambient temperatures is subject to
freezing.
Consult the specification sheets for piping sizes.
Teflon tape sealer should be used when
connecting to the unit to insure against leaks and
possible heat exchanger fouling. Do not
overtighten the connections. Flexible hoses should
be used between the unit and the rigid system to
avoid possible vibration. Ball valves should be
installed in the supply and return lines for unit
isolation and unit water flow balancing. Pressure/
temperature ports are recommended in both
supply and return lines for system flow balancing.
Water flow can be accurately set by measuring the
water-to-refrigerant heat exchangers water side
pressure drop. See specification sheets for water
flow vs. pressure drop information.
No unit should be connected to the supply or
return piping until the water system has been
completely cleaned and flushed to remove any dirt,
piping chips or other foreign material. Supply and
return hoses should be connected together during
this process to ensure the entire system is
properly flushed. After the cleaning and flushing
has taken place the unit may be connected to the
water loop and should have all valves wide open.

SM Series Heat Pump
SYSTEM CHECKOUT
After completing the installation, and before
energizing the unit, the following system checks
should be made:
• Verify that the supply voltage to the heat pump
is in accordance with the nameplate ratings.
• Make sure that all electrical connections are
tight and secure.
• Check the electrical fusing and wiring for the
correct size.
Ensure cabinet and Electrical Box are
properly grounded.
•
Verify that the low voltage wiring between the
thermostat and the unit is correct.
• Verify that the water piping is complete and
correct.
• Check that the water flow is correct, and
adjust if necessary.
• Check the blower for free rotation, and that it
is secured to the shaft.
• Verify that vibration isolation has been
provided.
• Unit is serviceable. Be certain that all access
panels are secured in place.
Considerations:
1. Always check incoming line voltage power
supply and secondary control voltage for
adequacy. Transformer primaries are dual
tapped for 208 and 230 volts. Connect the
appropriate tap to ensure a minimum of 18
volts secondary control voltage. 24 volts is
ideal for best operation.
2. Long length thermostat and control wiring
leads may create voltage drop. Increase wire
gauge or up-size transformers may be required
to insure minimum secondary voltage supply.
3. FHP recommends the following guidelines for
wiring between a thermostat and the unit: 18
GA up to 60 foot, 16 GA up to 100 ft and 14 GA
up to 140 ft.
4. Do not apply additional controlled devices to
the control circuit power supply without
consulting the factory. Doing so may void
equipment warranties.
5. Check with all code authorities on
requirements involving condensate disposal/
over flow protection criteria.
2. Set the thermostat system switch to “COOL”,
and the fan switch to the “AUTO” position. The
reversing valve solenoid should energize. The
compressor and fan should not run.
3. Reduce the thermostat setting approximately 5
degrees below the room temperature.
4. Verify the heat pump is operating in the cooling
mode.
5. Turn the thermostat system switch to the
“OFF” position. The unit should stop running
and the reversing valve should de energize.
6. Leave the unit off for approximately (5)
minutes to allow for system equalization.
7. Turn the thermostat to the lowest setting.
8. Set the thermostat switch to “HEAT”.
9. Increase the thermostat setting approximately
5 degrees above the room temperature.
10. Verify the heat pump is operating in the heating
mode.
11. Set the thermostat to maintain the desired
space temperature.
12. Check for vibrations, leaks, etc.
MAINTENANCE
1. Filter changes or cleanings are required at
regular intervals. The time period between
filter changes will depend upon type of
environment the equipment is used in. In a
single family home, that is not under
construction, changing or cleaning the filter
every 60 days is sufficient. In other
applications such as motels, where daily
vacuuming produces a large amount of lint,
filter changes may be need to be as frequent as
biweekly.
Equipment should never be used during
construction due to likelihood of wall board
dust accumulation in the air coil of the
equipment which permanently affects the
performance and may shorten the life of the
equipment.
2. An annual “checkup” is recommended by a
licensed refrigeration mechanic. Recording the
performance measurements of volts, amps,
and water temperature differences (both
heating and cooling) is recommended. This
data should be compared to the information on
the unit’s data plate and the data taken at the
original startup of the equipment.
UNIT START-UP
1. Set the thermostat to the highest setting.
SM Series Heat Pump
6 720 220 406 (2013/1)
46 | Maintenance
SM Series Heat Pump
3. Lubrication of the blower motor is not
required, however may be performed on some
motors to extend motor life. Use SAE-20 nondetergent electric motor oil.
4. The condensate drain should be checked
annually by cleaning and flushing to insure
proper drainage.
5. Periodic lockouts almost always are caused by
air or water flow problems. The lockout
(shutdown) of the unit is a normal protective
measure in the design of the equipment. If
continual lockouts occur call a mechanic
immediately and have them check for: water
flow problems, water temperature problems,
air flow problems or air temperature problems.
Use of the pressure and temperature charts for
the unit may be required to properly determine
the cause.

INSTALLATION
Position the thermostat subbase against the wall
so that it is level and the thermostat wires
protrude through the middle of the subbase. Mark
the position of the subbase mounting holes and
drill holes with a 3/16-inch bit. Install supplied
anchors and secure base to the wall. Thermostat
wire must be 8-conductor, 18-AWG wire. Strip the
wires back 1/4-inch (longer strip lengths may
cause shorts) and insert the thermostat wires into
the connector as shown. Tighten the screws to
ensure secure connections. The thermostat has
the same type connectors, requiring the same
wiring. See instructions in the thermostat for
detailed installation and operation information.

This chart shows approximate temperatures and pressures for a unit in good repair. The values shown are meant as
a guide only and should not be used to estimate system charge. This chart assumes rated air flow and 80º d.b./67º
w.b. entering air temperature in cooling, 70º d.b. entering air temperature in heating. Heating data at entering fluid
temperatures below 50º assumes the use of antifreeze. As a result of continuing research and development,
specifications are subject to change without notice.

This chart shows approximate temperatures and pressures for a unit in good repair. The values shown are meant as
a guide only and should not be used to estimate system charge. This chart assumes rated air flow and 80º d.b./67º
w.b. entering air temperature in cooling, 70º d.b. entering air temperature in heating. Heating data at entering fluid
temperatures below 50º assumes the use of antifreeze. As a result of continuing research and development,
specifications are subject to change without notice.
