IMPORTANT SAFETY INFORMATION
WARNINGS:
• These instructions are intended as an aid to
qualified, licensed service personnel for proper
installation, adjustment, and operation of this
unit. Read these instructions thoroughly before
attempting installation or operation. Failure to
follow these instructions may result in improper
installation, adjustment, service, or maintenance
possibly resulting in fire, electrical shock,
property damage, personal injury, or death.
• The unit must be permanently grounded. Failure
to do so can cause electrical shock resulting in
severe personal injury or death.
• Turn off electric power at the fuse box or service
panel before making any electrical connections.
• Complete the ground connection before making
line voltage connections. Failure to do so can
result in electrical shock, severe personal injury,
or death.
• Disconnect all power to unit before starting
maintenance. Failure to do so can cause
electrical shock resulting in severe personal
injury or death.
• Never assume the unit is properly wired and/or
grounded. Always test the unit cabinet with a
noncontact voltage detector available at most
electrical supply houses or home centers before
removing access panels or coming into contact
with the unit cabinet.
• Do not use oxygen to purge lines or pressurize
system for leak test. Oxygen reacts violently with
oil, which can cause an explosion resulting in
severe personal injury or death.
• The top of the scroll compressor shell is hot.
Touching the compressor top may result in serious
personal injury.
• The manufacturer’s warranty does not cover
any damage or defect to the unit caused by the
attachment or use of any components, accessories,
or devices (other than those authorized by the
manufacturer) into, onto, or in conjunction with
the heat pump. You should be aware that the
use of unauthorized components, accessories,
or devices may adversely affect the operation
of the heat pump and may also endanger life
and property. The manufacturer disclaims any
responsibility for such loss or injury resulting
from the use of such unauthorized components,
accessories, or devices.
CAUTIONS:
• R-410A systems operate at approximately 60%
higher pressures (1.6 times) than R-22 systems. Do
not use R-22 service equipment or components on
R-410A equipment. Use appropriate care when using
this refrigerant. Failure to exercise care may result in
equipment damage or personal injury.
• Only match this outdoor unit with a matched indoor
coil or air handler approved for use with this outdoor
unit per the unit manufacturer’s specification sheet.
The use of unmatched coils or air handler will likely
result in a charge imbalance between the cooling
and heating modes which can cause unsatisfactory
operation including a high-pressure switch lockout
condition.
• Only use indoor coils approved for use on R-410A
systems. An R-22 coil will have a TXV or fixed
restrictor device that is not designed to operate
properly in an R-410A system and will result in
serious operational issues. The R-22 coil could also
contain mineral oil which is incompatible with the
POE oil used in R-410A systems and could result in
reliability issues with the compressor and TXVs.
• When coil is installed over a finished ceiling and/or
living area, it is required that a secondary sheet metal
condensate pan be constructed and installed under
the entire unit. Failure to do so can result in property
damage.
• The compressor has an internal overload protector.
Under some conditions, it can take up to 2 hours for
this overload to reset. Make sure overload has had
time to reset before condemning the compressor.
• UNIT MAY START SUDDENLY AND WITHOUT
WARNING. A flashing red light on the heat pump/
defrost control indicates a call for unit operation is
present at the heat pump/defrost control. The heat
pump/defrost control will attempt to start unit after
the anti-short cycle time expires, when a high or low
pressure control automatically resets, or when the
heat pump/defrost control exits the lockout mode as
the temperature rises above 5°F.

GENERAL INFORMATION
WARNING:
Improper installation, or installation not made in
accordance with these instructions, can result
in unsatisfactory operation and/or dangerous
conditions and can cause the related warranty
not to apply.
The RP series of heat pumps are designed to
operate with standard 24 VAC thermostats and air
handlers or gas furnaces.
This installation instruction manual contains
complete instructions for installation and setup
using conventional 24 VAC controls. Please refer
to the manufacturer’s specification sheets for
complete performance data, thermostat, and
accessory listings.
The information contained in this manual has
been prepared to assist in the proper installation,
operation, and maintenance of the air conditioning
system.
General Information
Read this manual and any instructions packaged
with separate equipment required to make up the
system prior to installation. Homeowner should
retain this manual for future reference.
To achieve optimum efficiency and capacity,
the matching indoor cooling coils listed in the
manufacturer’s specification sheet must be used
for this model heat pump.
Checking Product Received
Upon receiving unit, inspect it for any shipping
damage. Claims for damage, either apparent or
concealed, should be filed immediately with the
shipping company. Check model number, electrical
characteristics, and accessories to determine if they
are correct. Check system components (indoor coil,
outdoor unit, air handler/furnace, etc.) to make sure
they are properly matched.
Application
Before specifying any heat pump equipment,
a survey of the structure and a heat loss and
heat gain calculation must be made. A heat loss
calculation involves identifying all surfaces and
openings that lose heat to the surrounding air
and quantifying that heat loss. A cooling heat
gain calculation makes similar measurements
and determines the amount of heat needed
to be removed. A heat gain calculation also
calculates the extra heat load caused by sunlight
and by humidity removal. These factors must
be considered before selecting a heat pump
system to provide year-round comfort. The Air
Conditioning Contractors of America (ACCA)
J Manual method of load calculation is one
recognized procedure for determining the heating
and cooling load.
After the proper equipment combination has
been selected, satisfying both sensible and
latent requirements, the system must be properly
installed. Only then can the unit provide the
comfort it was designed to provide.
There are several factors that installers must
consider.
• Outdoor unit location
• Indoor unit blower speed and airflow
• Proper equipment evacuation
• Supply and return air duct design and sizing
• Refrigerant charge
• System air balancing
• Diffuser and return air grille location and sizing

INSTALLATION
Choosing a Location
Location
IMPORTANT:
national building codes and ordinances for special
installation requirements. Following location
information will provide longer life and simplified
servicing of the outdoor heat pump.
Consult local and
NOTICE: These units must be installed
outdoors. No ductwork can be attached, or
other modifications made, to the discharge grille.
Modifications will affect performance or operation.
Operational Issues
IMPORTANT: Locate the unit
in a manner that will not prevent, impair, or
compromise the performance of other equipment
installed in proximity to the unit. Maintain all
required minimum distances to gas and electric
meters, dryer vents, and exhaust and inlet
openings. In the absence of national codes or
manufacturers’ recommendations, local code
recommendations and requirements will take
precedence.
• Refrigerant piping and wiring should be properly
sized and kept as short as possible to avoid
capacity losses and increased operating costs.
• Locate the unit where water runoff will not create
a problem with the equipment. Position the unit
away from the drip edge of the roof whenever
possible. Units are weatherized, but can be
affected by the following:
• Water pouring into the unit from the junction
of rooflines, without protective guttering.
Large volumes of water entering the heat
pump while in operation can impact fan blade
or motor life, and coil damage may occur to a
heat pump if moisture cannot drain from the
unit under freezing conditions.
• Freezing moisture or sleeting conditions can
cause the cabinet to ice-over prematurely
and prevent heat pump operation, requiring
backup heat, which generally results in less
economical operation.
• Closely follow the clearance recommendations
on page 8.
• 24" [61.0 cm] to the service panel access
• 60" [152.4 cm] above heat pump fan
discharge (unit top) to prevent recirculation
• 6" [15.2 cm] to heat pump coil grille air inlets
with 12" [30.5 cm] minimum recommended
Corrosive Environment
The metal parts of this unit may be subject to
rust or deterioration if exposed to a corrosive
environment. This oxidation could shorten the
equipment’s useful life.
Corrosive elements include, but are not limited to,
salt spray, fog or mist in seacoast areas, sulphur or
chlorine from lawn watering systems, and various
chemical contaminants from industries such as
paper mills and petroleum refineries.
If the unit is to be installed in an area where
contaminants are likely to be a problem, special
attention should be given to the equipment
location and exposure.
• Avoid having lawn sprinkler heads spray directly
on the unit cabinet.
• In coastal areas, locate the unit on the side of
the building away from the waterfront.
• Shielding provided by a fence or shrubs may
give some protection, but cannot violate
minimum airflow and service access clearances.
• Elevating the unit off its slab or base enough to
allow air circulation will help avoid holding water
against the base pan.
WARNING: Disconnect all power
to unit before starting maintenance. Failure to do
so can cause electrical shock resulting in severe
personal injury or death.
Regular maintenance will reduce the buildup of
contaminants and help to protect the unit’s finish.
• Frequent washing of the cabinet, fan blade, and
coil with fresh water will remove most of the salt
or other contaminants that build up on the unit.
• Regular cleaning and waxing of the cabinet with
a good automobile polish will provide some
protection.
• A good liquid cleaner may be used several times
a year to remove matter that will not wash off
with water.

For Units With Space
Limitations
In the event that a space limitation exists, we will
permit the following clearances:
Single-Unit Applications: Clearances below 6"
[15.2 cm] will reduce unit capacity and efficiency.
Do not reduce the 60" [152.4 cm] discharge or the
24" [61.0 cm] service clearances.
Multiple-Unit Applications: When multiple
condenser grille sides are aligned, a 6" [15.2
cm] clearance is recommended for 1.5 and 2
ton models and 9" [22.9 cm] for 2.5 ton to 5 ton
models. Two combined clearances below the
minimum will reduce capacity and efficiency. Do
not reduce the 60" [152.4 cm] discharge or 24"
[61.0 cm] service clearances.
Location
• If elevating a unit on a flat roof, use 4" x 4"
[10.2 cm x 10.2 cm] or equivalent stringers
positioned to distribute unit weight evenly and
prevent noise and vibration.
• Where snowfall is anticipated, raise the unit
above the base pad to prevent ice buildup and
coil damage. Mount the unit high enough to be
above the average accumulated area snowfall.
See “Ground Snow Depth” chart on page 10 for
representative snow depths.
NOTICE: Do not block drain openings on
bottom of unit.
• If unit must be elevated because of anticipated
snowfall, secure unit and elevating stand such
that unit and/or stand will not tip over or fall off.
Keep in mind that someone may try to climb on
unit.
Customer Satisfaction Issues
• The heat pump should be located away from the
living, sleeping, and recreational spaces of the
owner and those spaces on adjoining property.
• To prevent noise transmission, the mounting pad
for the outdoor unit should not be connected to
the structure and should be located a sufficient
distance above grade to prevent ground water
from entering the unit.
Unit Mounting
WARNING: Secure an elevated unit
and its elevating stand in order to prevent tipping.
Failure to do so may result in severe personal
injury or death.
Elevation of Unit
If elevating the heat pump, either on a flat roof or
on a slab, observe the following guidelines.
Factory-Preferred Tie-Down

Tools Required for Installing
and Servicing R-410A Models
Manifold Sets:
– Up to 800 PSIG High-Side
– Up to 250 PSIG Low-Side
– 550 PSIG Low-Side Retard
Manifold Hoses:
– Service Pressure Rating of 800 PSIG
Recovery Cylinders:
– 400 PSIG Pressure Rating
– Dept. of Transportation 4BA400 or BW400
CAUTION: R-410A systems operate
at higher pressures than R-22 systems. Do not
use R-22 service equipment or components on
R-410A equipment.
Specifications of R-410A
Application: R-410A is not a drop-in
replacement for R-22. Equipment designs must
accommodate its higher pressures. It cannot be
retrofitted into R-22 heat pumps.
Physical Properties: R-410A has an atmospheric
boiling point of -62.9°F [-52.7°C] and its saturation
pressure at 77°F [25°C] is 224.5 psig.
Composition: R-410A is a near-azeotropic
mixture of 50% by weight difluoromethane (HFC-
32) and 50% by weight pentafluoroethane (HFC-
125).
Pressure: The pressure of R-410A is
approximately 60% (1.6 times) greater than
R-22. Recovery and recycle equipment, pumps,
hoses, and the like must have design pressure
ratings appropriate for R-410A. Manifold sets
need to range up to 800 psig high-side and 250
psig low-side with a 550 psig low-side retard.
Hoses need to have a service pressure rating of
800 psig. Recovery cylinders need to have a 400
psig service pressure rating, DOT 4BA400 or DOT
BW400.
Combustibility: At pressures above 1
atmosphere, a mixture of R-410A and air can
become combustible. R-410A and air should
never be mixed in tanks or supply lines or
be allowed to accumulate in storage tanks.
Leak checking should never be done with a
mixture of R-410A and air. Leak-checking can
be performed safely with nitrogen or a mixture of
R-410A and nitrogen.
Quick-Reference Guide For
R-410A
• R-410A refrigerant operates at approximately
60% higher pressure (1.6 times) than R-22.
Ensure that servicing equipment is designed to
operate with R-410A.
• R-410A refrigerant cylinders are light rose in
color.
• R-410A, as with other HFCs, is only compatible
with POE oils.
• Vacuum pumps will not remove moisture from
POE oil used in R-410A systems.
• R-410A systems are to be charged with liquid
refrigerants. Prior to March 1999, R-410A
refrigerant cylinders had a dip tube. These
cylinders should be kept upright for equipment
charging. Post-March 1999 cylinders do not
have a dip tube and should be inverted to ensure
liquid charging of the equipment.
• Do not install a suction line filter drier in the
liquid line.
• A factory-approved biflow liquid line filter drier
is shipped with every unit and must be installed
in the liquid line at the time of installation. Only
manufacturer-approved liquid line filter driers can
be used. These are Sporlan (CW083S) and Alco
(80K083S) driers. These filter driers are rated for
minimum working pressure of 600 psig. The filter
drier will only have adequate moisture-holding
capacity if the system is properly evacuated.
• Desiccant (drying agent) must be compatible for
POE oils and R-410A refrigerant.

INSTALLATION
Replacement Units
Tubing
To prevent failure of a new unit, the existing line set
must be correctly sized and cleaned or replaced.
Care must be exercised that the expansion device
is not plugged. For new and replacement units, a
liquid line filter drier must be installed and refrigerant
tubing must be properly sized. Test the oil for acid. If
positive, a suction line filter drier is mandatory.
Indoor Coil
CAUTION: Only use evaporators
approved for use on R-410A systems that are
specifically matched with the outdoor unit per
the manufacturer’s specification sheets. Use
of existing R-22 evaporators can introduce
mineral oil to the R-410A refrigerant, forming two
different liquids and decreasing oil return to the
compressor. This can result in compressor failure.
REFER TO INDOOR COIL MANUFACTURER’S
INSTALLATION INSTRUCTIONS.
IMPORTANT: The manufacturer is not
responsible for the performance and operation of
a mismatched system or for a match listed with
another manufacturer’s coil.
NOTICE: All outdoor units must be
installed with a matched TXV indoor coil. Refer to
manufacturer’s outdoor unit specification sheet for
approved indoor coils.
IMPORTANT: When replacing an
R-22 unit with an R-410A unit, either replace
the line set or ensure that residual mineral oil is
drained from existing lines including oil trapped in
low spots.
The thermostatic expansion valve in the
matching coil is specifically designed to operate
with R-410A. DO NOT use an R-22 TXV or
evaporator. The existing evaporator must
be replaced with the factory-specified TXV
evaporator specifically designed for R-410A.
Location
Do not install the indoor coil in the return duct
system of a gas or oil furnace. Provide a service
inlet to the coil for inspection and cleaning. Keep
the coil pitched toward the drain connection.
CAUTION: When coil is installed
over a finished ceiling and/or living area, it is
required that a secondary condensate pan be
installed under entire unit. Failure to do so can
result in property damage.
12
Interconnecting Tubing
The purpose of this section is to specify the
best construction/sizing practices for installing
interconnection tubing between the indoor and
outdoor unit.
Refrigerant Level Adjustment
All units are factory-charged with R-410A
refrigerant to cover 15 feet of standard size
interconnecting liquid and vapor lines with a
required field installed filter drier. Adjustment of
charge may be necessary even if the application
has exactly 15 feet of line set due to other
installation variables such as pressure drop,
vertical lift, and indoor coil size. For different
lengths, adjust the charge as indicated below.
• 1/4" ± .3 oz./foot [6.4 mm ± 8.5 g/.30 m]
• 5/16" ± .4 oz./foot [7.9 mm ± 11.3 g/.30 m]
• 3/8" ± .6 oz./foot [9.5 mm ± 17.0 g/.30 m]
• 1/2" ± 1.2 oz./foot [12.7 mm ± 34.0 g/.30 m]
• 6 oz. required factory supplied field-installed
• filter drier.
Charge Adjustment = (Line Set (oz./ft.) x Total
Length) – Factory Charge for Line Set
Example: A three ton heat pump unit with factory
installed 3/8” liquid service valve requires 75 ft. of
line set with a liquid line diameter of 1/2”.
Factory Charge for Line Set = 15 ft. x .6 oz. = 9 oz.
Charge Adjustment = (1.2 oz. x 75 ft.) – 9 oz. =
+ 81 oz.

Liquid Line Selection
The purpose of the liquid line is to transport warm
sub-cooled liquid refrigerant from the outdoor unit
to the indoor unit. It is important not to allow the
refrigerant to fl ash any superheated vapor prior
to the expansion device of the indoor coil. The
fl ashing of refrigerant can occur for the following
reasons:
• Low refrigerant charge
• Improperly selected liquid line size
• Absorption of heat prior to expansion device
• Excessive vertical rise between the condenser
and evaporator
Table 2 lists the equivalent length per 25’ of liquid
line at various diameters up to 300’. The total pres-
tubing length, fi ttings, vertical separation, acces-
sories, and fi lter dryers. The table below references
diff erent commonly used equivalent lengths.
Table 1
Solenoid
Valve
sure drop allowed for the liquid line is 50 PSI. The
procedure for selecting the proper liquid line is as
follows:
• Measure the total amount of vertical rise
• Measure the total amount of liquid line needed
• Add all of the equivalent lengths associated with

• Add the total length and fi tting pressure drop.
This will equal your total equivalent length.
• Round-down the total equivalent length to the
closest value in Table 2.
• Reference Table 2 to verify the rounded-down
value of the calculated equivalent length is compatible with the required vertical rise and diameter of liquid line.

Example: A 3-Ton heat pump unit is installed 50’
below the ID unit, requires a 75’ of 1/2” diameter
liquid line, and 4 90° LR elbows.
• Fitting Equivalent Length (ft.) = 4 x .9 = 3.6’
• Total Equivalent Length (ft.) = 75’ + 3.6’ = 78.6’
• Rounded-down value (ft.) = 75’

Long Line Set Applications
Long line set applications are defi ned as applica-
tions that require accessories or alternate construction methods. The following are special considerations that need to be addressed when installing a
long line set application:
• Additional refrigerant charge
• Fitting losses and maximum equivalent length
Tubing
considerations
• Refrigerant migration during the off cycle
• Oil return to the compressor
• Capacity losses
• System oil level adjustment
Table 2 is used to determine if the application is
considered to have a long line set. The region of
the chart that is shaded grey is considered to be
a long line set application.
Oil Level Adjustments for Long
Line Set Applications
Additional oil will need to be added for long line set
applications. (Ref. Table 2). Below is the equation for
the oil level adjustment and the compressor name
plate oil charge for the diff erent od units.
Oil to be Added = [(Charge Adjustment + OD
Unit Name Plate Charge (oz.)) x (0.022) – [(0.10) x
(Compressor Name Plate Oil Charge (oz.))]
Example: An application requires 125ft of line set
with a liquid line diameter of 3/8”, Charge Adjustment = 52.4 oz., Name Plate Charge = 107 oz.,
Name Plate Oil Charge = 25 oz., Oil to be Added =
((52.4 oz. +107 oz.) x .022) – (.10 x 25 oz.) = 1.0 oz.
This application is acceptable because the 50’
vertical rise is less than the maximum rise of 75’ for
this application. The application is also considered
to have a long line set. Reference the long line set
section of the I&O for detail.

Suction Line Selection
Purpose of the suction line is to return superheated
vapor to the condensing unit from the evaporator.
Proper suction line sizing is important because it
plays an important role in returning oil to the compressor to prevent potential damage to the bearings, valves, and scroll sets. Also, an improperly
sized suction line can dramatically reduce capacity
and performance of the system. The procedure for
selecting the proper suction line is as follows:
• The total amount of suction line needed
• Add all of the equivalent lengths associated with
any fi ttings or accessories using the table on
previous page.
• Add the total length and fi tting pressure drop.
This will equal your total equivalent length.
• Reference Table 2 to verify that the calculated
equivalent length falls within the compatibility
region of the chart.
• Verify Table 3 to verify the capacity diff erence is
compatible with the application.
Refrigerant Migration During
Off Cycle
Long line set applications can require a considerable amount of additional refrigerant. This additional refrigerant needs to be managed throughout the
entire ambient operating envelope that the system
will go through during its life cycle. Off -Cycle mi-
gration is where excess refrigerant condenses and
migrates to the lowest part of the system. Excessive build-up of refrigerant at the compressor will
result in poor reliability and noisy operation during
startup. This section demonstrates the required
accessories and unit confi guration for diff erent ap-
plications.
