DO NOT locate the unit:
General
– Directly under a vent termination for a gas appliance.
– Within 3 feet of a clothes drier vent.
This manual covers only the installation of the remote heat
pump. See the unit specification sheet for information
regarding accessories.
– Where the refreezing of defrost water would create
a hazard.
– Where water may rise into the unit.
SHIPPING AND HANDLING
– Where the noise would prove to be a nuisance to the
customer (i.e. windows, patios, decks, etc.)
Units are securely packed in shipping containers ap-
provedbytheInternationalSafeTransitAssociation. Check
the carton upon arrival for external damage. If damage is
found, file a request in writing for inspection by the carrier
agent immediately. The carrier is responsible for making
prompt inspection of damage and for a thorough investiga-
tion of each claim. The distributor or manufacturer will not
accept claims from dealers for transportation damage. If
no damage is found, carefully remove all shipping material
and properly dispose of it.
DO locate the unit:
– With the bottom of the unit at least three inches
above the maximum expected snow accumulation
level.
– Inaccordancewiththeminimumclearancesdescribed
in Figure 1.
– To minimize the length of refrigerant piping required.
– To provide adequate service clearances.
– On a level concrete pad (or other sturdy, weather
resistant platform).
Keep the unit as upright as possible. Laying the unit on its
side or top could cause equipment damage.
– Isolated from the building structure to avoid transmis-
sion of vibrations.
LOCATION AND CLEARANCES
This unit is for outdoor installation only. The unit cannot be
completely enclosed. At least one side must be unre-
stricted. Refer to Figure 1 for clearances from the sides
and top of the unit to walls and other objects.
NOTE: Short runs of refrigerant piping are better than long
runs. Locate the unit to provide safe access for future
maintenance and service. If possible, discuss unit location
with the owner before proceeding.
NOTE: These minimum clearances do not guarantee
adequate service access. Sufficient clearances for servic-
ing the unit(s) must be provided.
ROOFTOP INSTALLATIONS
Before installing this unit on a roof, ensure that the roof will
support the weight of the unit, its platform, and the service
personnel. For the unit weight, see the outdoor unit
specification sheet (all weights are approximate). If there
is doubt about the adequacy of the roof, contact a qualified
architect or structural engineer before installing the unit.
Ensure the unit is placed on a level, weather-resistant
platform.
If installing two or more units at the same location, allow at
least 24 inches between the units when using the 6”-12”-
12” guidelines in Figure 1. The space between two units
may be reduced to 12” if the clearances in Figure 1 are
increased to 12”-24”-24”.
MINIMUM CLEARANCES
APPLICATION NOTE
For proper performance, the indoor equipment and duct-
work must be adequate for moving about 400 CFM of
indoor air for every ton of cooling capacity to be installed.
If they are not, modify the ductwork or indoor equipment
accordingly.

Refrigerant Piping
REFRIGERANT VAPOR AND LIQUID LINE SIZING
See unit “Specification Sheet” for the required vapor and
liquid line tubing sizes. The listed sizes in the specification
sheet are suitable for line lengths of fifty feet or less and
indoor coil elevations of no more than forty feet above or
below the outdoor unit. NOTE: Unit performance is
affected by vapor line tubing size. A larger than required
vapor line tubing inhibits oil return to the unit. A smaller
than required vapor line tubing size decreases unit perfor-
mance by up to 10%. If a run of more than fifty feet is
required, contact your Amana distributor for assistance.
SIDE VIEW
Figure 1
Check the indoor coil liquid and vapor line diameter. A
bushing or coupling may be needed to match with the line
3
sizes used. If mix-matching to a restrictor orifice indoor
coil, check the “Specification Sheet” for the proper orifice
size to be used with this outdoor unit. Piston orifices are
supplied with the outdoor unit.
Safe Refrigerant Handling
WARNING
To avoid possible explosion, death, or
injury; practice safe handling of
refrigerants.
REFRIGERANT VAPOR AND LIQUID LINE ROUTING
All of the vapor line must be insulated. The insulation must
include a vapor barrier.
The unit liquid line must be outside the vapor line insula-
tion. If any part of the liquid line runs through an area that
will be hotter than 120°F, that part must be insulated.
While these items will not cover every conceivable situa-
tion, they should serve as a useful guide.
Avoid burying refrigerant lines. If you must bury them, first
dig the trench so that it gradually slopes toward the
compressor (at least 1 inch per 10 feet). Then, insulate the
liquid and suction lines separately. Enclose all under-
ground portions of the refrigerant lines in waterproof ma-
terial (conduit or pipe). If the lines must pass under or
through a concrete slab, be sure they are adequately
protected.
WARNING
Refrigerants are heavier than air. They can
“push out” the oxygen in your lungs or in
any enclosed space. To avoid possible
death or difficulty in breathing:
• Never sniff a refrigerant.
• Seal the holes where the refrigerant piping enters
the building and support piping as necessary.
• Never purge refrigerant into an enclosed
room or space. In fact, all refrigerants
must, BY LAW, be recovered.
• Be careful not to kink or dent the refrigerant lines.
Kinked or dented lines will cause poor perfor-
mance or compressor damage.
• Ifanindoorleakissuspected,thoroughly
ventilatetheareabeforebeginningwork.
• Liquid refrigerant can be very cold. To
avoid possible frostbite or blindness,
avoid contact and wear gloves and
goggles. Ifliquidrefrigerantdoescontact
your skin or eyes, get medical help
immediately.
CAUTION
To prevent damage to the unit, a bi-flow
filter drier must be installed in the liquid
line.
Install the bi-flow line filter drier shipped with the unit near
the condensing unit or near the indoor coil. A new filter
drier (properly sized and rated for R-22) MUST be installed
with new outdoor units in order for the compressor war-
ranty to remain valid. Any time the refrigeration system has
been opened for service, a new properly-sized bi-flow filter
drier rated for R-22 must be installed.
• Always follow EPA regulations. Never
burn refrigerant, as poisonous gas will
be produced.
WARNING
To avoid possible explosion:
SWEAT CONNECTIONS AT THE UNIT
• Neverapplyflameorsteamtoarefrigerant
cylinder. If you must heat a cylinder for
faster charging, partially immerse it in
warm water.
• Never fill a cylinder more than 80% full of
liquid refrigerant.
NOTE: When brazing, use a brazing alloy of 2% minimum
silver content. Do not use flux.
Before brazing connections, ensure the refrigerant line
ends are cut square, deburred, cleaned, free of nicks or
dents and round. Any other condition would increase the
chance of refrigerant leakage.
• Never add anything other than R-22 an
R-22 cylinder.
• Storecylindersinacool,dryplace. Never
During brazing, wrap the component with a wet rag, or use
a thermal heat trap compound as directed by the com-
pound manufacturer, to avoid overheating the service
valve, TXV valve, or filter drier while brazing.
use a cylinder as a platform or a roller.
After brazing, quench the joints with water or a wet cloth to
prevent overheating of the service valve. Inspect the paint
finish of the filter drier. The finish must be intact after
brazing. If the paint of the steel filter drier has been burned
or chipped, repaint or treat with a rust preventative. This
is especially important on suction line filter driers which are
continually wet during the unit operation.

WARNING
6. Close the valve on the nitrogen cylinder and discon-
nect it from the gauge manifold.
To avoid possible explosion, use only
returnable (not disposable) service
cylinders when removing refrigerant from
a system.
7. Check for leaks. Apply a soap solution on all connec-
tions and joints. If you see bubbles, you have a leak.
Mark these locations.
NOTE: If you use an electronic leak detector to test for
leaks, add a trace of R-22 to the system (if permitted by
current EPA regulations) before testing.
• Ensure the cylinder is free of damage
which could lead to a leak or explosion.
• Ensurethehydrostatictestdatedoesnot
exceed 5 years.
8. Using the gauge manifold, carefully release the nitro-
gen from the system. If leaks are found, repair them.
After repair, repeat the above pressure test. If no leaks
exist, proceed to ID Coil and Line Sets Evacuation.
• Ensure the pressure rating meets or
exceeds 400 psig.
When in doubt, do not use cylinder.

3. Connect a cylinder of dry nitrogen to the center port on
the gauge manifold.
Figure 2
WARNING
Step 1. Confirm Proper Pump And Gauge Operation
To avoid possible explosion, the line from
the nitrogen cylinder must include a
pressure regulator and a pressure relief
valve. The pressure relief valve must be
set to open at no more than 150 psig.
a. Connect vacuum pump, high vacuum manifold set
with high vacuum hoses, vacuum gauge and charging
cylinder to unit service valves as shown in Figure 2.
Ensure all manifold valves are fully closed.
b. Open the shutoff valve leading to the vacuum pump
(Figure 2) (C), start the pump, and watch the gauge
manifold. The readings in the gauge manifold should
drop to approximately 29 inches Hg. If this does not
happen, there is probably a leak in the pump and
gauge system. Repair the leak and test again.
4. Open the hand valve a minimal amount on the line
coming from the nitrogen cylinder.
5. Open the high pressure valve on the manifold gauge.
Pressurize the refrigerant lines and the indoor coil to
150 psig (1034 kPA). To reach 150 psig, you may
need to further open the hand valve on the nitrogen
cylinder.
c. Open the vacuum gauge valve (D) and evacuate to
250 microns or less. If the system cannot be evacu-
ated, replace the vacuum pump equipment and repeat
steps (a) through (c) again. Otherwise, the pump and
gauge are operating properly and you can continue on
to the next step; evacuating the system. Before
proceeding, be sure to close the valve (D) to the
vacuum gauge to avoid “pegging the meter” and
potential gauge damage.
WARNING
To avoid possible explosion or equipment
damage, do not exceed 150 psig when
pressure testing.

Step 2. Evacuate Lines And Indoor Coil.
a. Openthehighandlowsidevalves(B&A)onthegauge
manifold. NOTE: Only open the valve (E) on the
gauge manifold leading to the cylinder, not the valve
on the charging cylinder (F).
b. Evacuate the system to about 29 inches Hg as mea-
sured by the low side (compound) gauge.
c. Open the valve (D) to the vacuum gauge. Evacuate
until the gauge reads 250 microns or less.
d. Close the valve to the vacuum pump (C). Wait five
minutes, then check the pressure on the vacuum
gauge:
1. If the pressure is not more than 1500 microns, the
system is leak-free and properly evacuated. Pro-
ceed to step (e).
2. If the pressure rises, but holds at about 5000 mi-
crons, moisture and noncondensibles are still
present. Open the valve to the vacuum pump (E),
and go back to step (c).
3. If the pressure rises above 5000 microns, a leak is
present. Go back to “Leak Testing” section on page
4.
e. Close the valve to the vacuum gauge.
f. Close the valve to the vacuum pump. Shut off the
pump.

WARNING
Turn the electrical power on, and let the system run for
several minutes. It will take some time for the refrigerant
pressures to stabilize.
To avoid personal injury or death, open
eachvalveonlyuntilittouchestheretainer.
To avoid loss of refrigerant, do not apply
pressure to the retainer.
Compare the operating pressures and outdoor unit amp
draw to the numbers listed in the outdoor unit “Specifica-
tion Sheet”. If pressures and amp draw are too low, add
charge. If pressures and amp draw are too high, remove
charge.
The outdoor unit is factory-charged with enough R-22 for
the matching indoor blower coil or matching A-coil plus 25
feet of 3/8” liquid line. For liquid line lengths greater than 25
feet, add 0.55 oz. of R-22 per additional foot up to 50 feet.
For line sets over 50 feet consult an Amana distributor. For
liquid line lengths less than 25 feet, subtract 0.55 oz. of R-
22 per deviating foot.
If you are not using the “Matched Combination” which is
listed on the unit "Specification Sheet", check subcooling
(TEV coils) or superheat (flowrator coils) as detailed be-
low.

EXAMPLE: The low side pressure is 84 psi. The low side
temperature is 80°F. The outdoor temperature is 95°F.
The indoor temperature is 85°F. By referring to a pressure
temperature chart, you will see that 84 psi equals a
saturated temperature of 50°F. The superheat is 80 - 50
= 30°F. The chart shows a superheat of 20°F is ideal for
these conditions. Since our superheat is 30 - 20 = 10°F
higher than ideal, charge must be added.

NOTE: If the time select pin remains in test position for 5
minutes, the control will ignore test mode and assume a
normal 90 minute defrost cycle. To over ride this time out,
remove the select pin briefly and replace back on test.
If the system is performing properly, reinstall the service
port caps and the valve bonnets. With the valve opened,
the valve bonnet is the primary seal against refrigerant
leaks. See the table below for the torque required for an
effective seal on the valve bonnet (1/6 turn past finger
tight).

If adjustment of the run time appears advisable:
1. Disconnect power to outdoor unit.
After closing the valve bonnet, perform a final refrigerant
leak test on the valves and sweat connections. Return the
room thermostat to the desired settings.
2. Move the defrost time adjustment pin from 90 minutes
to60minutesor30minutesasrequired(refertoFigure
5).
3. Reconnect the electrical power.
The maximum defrost time is 14 minutes. Most defrost
cycles are shorter.
Troubleshooting
SERVICING: When servicing, it may be necessary to
rapidly advance the system through a defrost cycle. To do
this:
(QUALIFIED SERVICER ONLY)
When troubleshooting, the first step should always be to
check for clean coils, clean filter(s), and proper airflow.
Indoor airflow should be 350 to 450 CFM per ton of cooling,
based on the size of the outdoor unit.
Place the defrost time adjustment pin on Test. When the
unit starts the defrost cycle, quickly remove the time select
pin to allow normal defrosting and defrost termination to
proceed. The select pin may be reconnected to test or
repeat the defrost cycle, or the pin may be placed in the
desired time setting. (Jumping both test pins with a small
insulated screw driver will also work.)
If further information is needed, see the Remote Heat
Pump Service Manual or contact your Amana distributor.
Defrost System
WARNING
Your unit is equipped with a time/temperature defrost
board. Defrosting of the outdoor coil is determined by both
coil temperature and compressor run time. See the
“Specification Sheet” for factory settings. Adjustment can
be changed as required. There are 30, 60, and 90 minute
settings available. Adjust only if geographical conditions,
outdoor humidity, or other adverse conditions make it
necessary.
To avoid electrical shock or death,
disconnect the electrical power before
servicing.
