codes or, in the absence of local codes, with the
the National Electrical Code NFPA 70/ANSI
C1-1999 or current edition and Canadian
Electrical Code Part 1 CSA C.22.1.
The information contained in this manual is
intended for use by a qualified service technician
familiar with safety procedures and equipped
with the proper tools and test instruments.
Failure to carefully read and follow all instruc-
tions in this manual can result in equipment
malfunction, property damage, personal injury
and/or death.
After uncrating unit, inspect thoroughly for hidden damage.
If damage is found, notify the transportation company im-
mediately and file a concealed damage claim.
Locating The Outdoor Unit:
CAUTION
Improper installation, adjustment, alteration, service or
maintenance can void the warranty.
The weight of the condensing unit requires caution and
proper handling procedures when lifting or moving to avoid
personal injury. Use care to avoid contact with sharp or
pointed edges.
Safety Precautions
1. Always wear safety eye wear and work gloves when
installing equipment.
2. Never assume electrical power is disconnected. Check
with meter and disconnect.
3. Keep hands out of fan areas when power is connected
to equipment.
4. R-22 causes frost-bite burns.
5. R-22 is toxic when burned.
NOTE TO INSTALLING DEALER: The Owners Instruc-
tions and Warranty are to be given to the owner or promi-
nently displayed near the indoor Furnace/Air Handler Unit.
Check local codes covering zoning, noise, platforms.
If practical, avoid locating next to fresh air intakes, vent or
bedroom windows. Noise may carry into the openings and
disturb people inside.
Placement of the unit should be in a well drained area or
unit must be supported high enough so runoff will not enter
the unit.
Do not locate where heat, lint or exhaust fumes will be dis-
charged on unit (as from dryer vents).
Roof top installations are acceptable providing the roof will
support the unit and provisions are made for water drain-
age and the noise or vibration through the structure.
Do not install the unit in a recessed or confined area where
recirculation of discharge air may occur.
Heat Pumps Only: The top surface of platform must be
above average winter snow levels to prevent coil blockage.

_Installation Instructions Split System Condensers I
Clearances:
Nominal operating clearances, where practical, are 60
inches (150 cm) above unit for discharge air and 24 inches
(40cm) around coil for intake air on three sides. Clearance
on one side (normally between unit and structure) may be
reduced to 12 inches (30cm). Nominal clearances are
based from a solid parallel object, wall, roof overhang, etc.
Do Not install under roof overhangs without guttering. A
minimum vertical clearance of 60" is required to overhang.
The clearance may be reduced from a single object with a
small surface area, such as the end of a wall, outside cor-
ner of a wall, fence section or a post, etc. As a general rule
the width of the object should equal the minimum clearance
from the unit. For example, a 4 inch (10cm) fence post
could be 4 inches (10cm) from the unit.
Unit Support:
Inside corner locations on single story structures require
evaluation. Large overhanging soffits may cause air recir-
culation in a corner area even though recommended clear-
ances are maintained. As a guide locate the unit far enough
out so that half of the discharge grille is out from under the
soffit.
Two or more units may be spaced with 20 inches (50cm)
between units.
A service clearance of 24 inches (60cm) is desirable from
control box end or side. Control box and corner panel be-
low it can be loosened and moved out to the side to facili-
tate servicing. Internal components can be accessed
through control box corner or top only.
The unit must be level, and supported above grade by
beams, platform or a pad. Platform or pad can be of open or
solid construction but should be of permanent materials
such as concrete, bricks, blocks, steel or pressure treated
timbers approved for ground contact. Refer to Unit Clear-
ances to help determine size of supports etc. Soil condi-
tions should be considered so the platform or pad does not
shift or settle excessively and leave the unit only partially
supported.
CAUTION
Inadequate support could cause excessive vibration and
noise or binding and stress on refrigerant lines resulting in
equipment failure.
To minimize vibration or noise transmission, it is recom-
mended that supports not be in contact with the building
structure. However, slabs on grade constructions with an
extended pad are normally acceptable.
A. Ground Level Installation:
If beams or an open platform are used for support it is rec-
ommended that the soil be treated or area be graveled to
retard the growth of grasses and weeds.
B. Roof Top Installation:
This type of installation is not recommended on wood
frame structures where low noise levels are required.
Supporting structure or platform for the unit must be level. If
installation is on a flat roof the unit should be 4 inches
(10cm.) above roof level. Four by four posts placed over a
load bearing wall make a suitable mounting platform.
If possible, place the unit over one or more load bearing
walls. If there are several units, mount them on platforms
that are self-supporting and span load bearing walls.
These suggestions are to minimize noise and vibration
transmission through the structure. If the structure is a
home or apartment, avoid (if practical) locating the unit
over bedrooms or study.
NOTE: When condensing unit is to be installed on a
bonded guaranteed roof, a release must be obtained from
the building owner to free the installer from all liabilities.

Installing Refrigerant Lines
Component Matches
Check to see that you have the proper system compo-
nents. APPROVED MATCHED SYSTEM COMPON ENTS
MUST BE USED. Refer to the Sales Specification Sheet
or Split System Summary for match data and orifice
sizes,
The outdoor units are shipped with a refrigerant charge to
match the indoor unit and 15 ft. (4.5m) of refrigerant line. If
shorter or longer lines are used, the charge will have to be
adjusted.
TOTAL LENGTH OF REFRIGERANT LINES MUST NOT
EXCEED 50 ft. WITH A MAXIMUM VERTICAL SEPARA-
TION OF 40 ft. BETWEEN THE OUTDOOR AND IN-
DOOR UNITS.
PLEASE! UNDER NO CIRCUMSTANCES LEAVE THE
LINES OPEN TO THE ATMOSPHERE FOR ANY
PERIOD OF TIME,
Be extra careful with sharp bends. This tubing can "kink"
very easily, and if this occurs, the entire tube length will
have to be replaced. Extra care at this time will eliminate
future service problems.
Suspension And Installation Of
Refrigeration Lines
DO NOT fasten liquid or suction lines in direct contact with
the floor or ceiling joist. Use an insulated or suspension
type of hanger. Keep both lines separate, and insulate the
suction line. Both lines should be insulated in long runs in
an attic or underground in a raceway.
Restrictor Orifice
Some indoor matches use a restrictor orifice in the fitting at
the indoor coil. Some matches may require a different ori-
fice for proper system performance and it must be changed
before the refrigerant lines are connected.
Changing the Restrictor Orifice
The restrictor orifice is located in a fitting in the liquid line.
The fitting is actually the distributor end of the cap tube as-
sembly.
1. Remove the liquid line fitting and replace restrictor ori-
fice. (STANDARD RIGHT HAND THREAD)
2. Make sure the restrictor is installed with the rounded
end toward the feeder tubes. See Figure 3.

_Feeder Tubes
Refrigeration Line Sets
Ifit is necessary to add tubing in the field, use dehydrated or
dry sealed deoxidized copper refrigeration tube. DO NOT
use copper water pipe.
It is important that no tubing is cut or seals broken until
you are ready to actually make connections to the
evaporator and to the condenser section.
Do not remove rubber plugs or copper caps from the
tube ends until ready to make connections at evapora-
tor and condenser.
Do not let refrigerant lines come in direct contact with
foundation. When running refrigerant lines through the
foundation or wall, the openings should be made large
enough to allow for a sound absorbing material to be
placed or installed between the tubing and the foundation.
This will prevent noise transmission between the tubing
and the wall section (foundation) or the building.
Installation Instructions For Condensing
Units That Are Higher Than Evaporator
It is recommended that vertical suction risers not be up-
sized. Proper oil return to the compressor should be main-
tained with suction gas velocity. If velocities drop below
1500 fpm (feet per minute), oil return will be decreased. An
oil trap should be installed every 20' of vertical suction line
riser (condenser above evaporator.) Refer to line sizing
charts.

Line Valves
The outdoor condensing unit is supplied with straight sweat
brass service valves with copper stubs.
_J 421 01 3002 01
I Split System Condensers Installation Instructions
All line valves are positioned to seal the refrigerant in the
condensing unit with gauge ports open to connecting lines
when the Schraeder valve is depressed. Gauge ports have
Schraeder installed and require use of charging hoses with
depressors.
Brazing Connections
Fire Hazard
Refrigerant and oil mixture under pressure could
ignite as it escapes and contacts brazing torch
resulting in Fire. Make sure the refrigerant charge
is properly removed from both the high and low
sides of the system before brazing any compo-
nent or lines.
FAILURE TO DO SO COULD RESULT IN BODILY
INJURY OR DEATH.
Before making braze connections, be sure all joints are
clean. Before heat is applied for brazing, nitrogen should
be flowing through the tubing to prevent oxidation and
scale formation on the inside of the tubing.
Liquid & Suction Lines
Fully annealed refrigeration lines should be used when
installing the system.
The following is the recommended method for making
braze connections at the refrigerant line connections:
1. Clean refrigerant tube end with emery cloth or steel
brush.
2. Use a suitable brazing alloy for copper to copper joints.
3. Insert tubing into swage fitting connection.
4. Apply heat absorbing paste or heat sink product to pre-
vent damage to the service valve.
CAUTION
Do not heat valve body above 250 degrees R
5. Braze joint.
6. Quench the joint and tubing with water using a wet rag.
Leave rag on fitting body and re-wet with water to help cool
area.
Evacuating, And Charging Instructions
NOTE
Intentional release of CFC or HCFC Refrigerant to the
Atmosphere violates Federal Law, It may also violate
State and Local Codes, Check all Federal, State and
Local Codes before proceeding,
These instructions are intended for use with condensing
units that are precharged at the factory with adequate re-
frigerant to handle 15 feet.
NOTE: Do not use any portion of the charge for purging or
leak testing. It is mandatory that a thorough evacuation of
the refrigerant in the piping and evaporator be performed.
The liquid line and suction line service valves have been
closed after final testing at the factory. Do not disturb
these valves until the lines have been leak checked
and evacuated or the charge in the unit may be lost,
Recommended Method Of Evacuating A
System
1. Connect the vacuum pump to the suction and liquid line
gauge ports.
2. If the evacuation is being performed on a new system
installation, the valves should be kept in the "front seated"
(closed) position. This will allow the mechanic to evacuate
the refrigeration lines and the indoor coil, without disturbing
the factory charge in the outdoor unit.
3. Follow the vacuum pump manufacturer's instructions.
Allow the pump to operate until the system has been eva-
cuated down to 300 microns. Allow the pump to continue
running for an additional 15 minutes. Turn off the pump and
leave the connections secured to the two service valves.
After 5 minutes, if the system fails to hold 500 microns or
less, check all connections for tight fit and repeat the evac-
uation procedure.
4. Isolate the vacuum pump from the system by closing the
shutoff valves on the gauge bar. Disconnect the vacuum
pump.
Valve Actuation: Service Valves
Remove the service valve cap, if there is a male valve stem
see instructions for Ball Valves. For the standard service
valve there are two variations, but both have internal
stems. The first style uses an internal snap ring to retain the
valve stem and the second has a rolled top and also has
finer threads on the valve cap. NOTE: You may encounter
more than one type of valve on a unit,
For service valves fully insert a hex wrench into the stem. A
back-up wrench is required on the valve body to open the
valve stem. Backout counterclockwise until the valve stem
stops or just touches the retaining ring. NOTE: THIS IS
NOT A BACKSEATING VALVE. For valves with retainer
rings care must be taken to prevent dislodging them when
opening valve.
The service valve cap is a primary seal for the valve and
must be properly tightened to prevent leaks. Make sure cap
is clean and apply refrigerant oil to threads and sealing sur-
face of cap.
For valves with retaining rings: Replace service valve
cap and torque to; 8-11 ft. Ibs. on 1/4" and 3/8" valves,
12-16 ft. Ibs. on 5/8" and 3/4", 15-21 ft. Ibs on 7/8" valves. If
torque wrench is not available, tighten cap finger tight and
then tighten one (1) additional wrench flat or 1/6 of a turn.
For valves with rolled tops: Replace service valve cap
tighten cap finger tight and then tighten one (1) additional
wrench flat or 1/6 of a turn to properly seat the sealing sur-
faces. Subsequent installations will seat with 1/2 to 1
wrench flat of turning.
Gauge Ports: All Valves
Check for leaks at the schrader port and tighten valve core
if necessary. Install plastic caps finger tight.
Ball Valves
On models with ball type valves use a 6" crescent wrench
to rotate the valve stem 90°counter clockwise. Retighten
valve cap to 6-8 ft. Ibs. If torque wrench is not available,
tighten cap finger tight and then tighten one (1/2) additional
wrench flat.

REFRIGERATION PIPING & CHARGING
The recommended method of addition or removal of refrig-
erant is by weight.
Some matching coils may need more refrigerant than the
factory charge. If you can't determine charge by weight,
then check charge by superheat method and performance
curves. The oil charge is sufficient for 50 feet.
For oil requirements refer to Figure 5. For piping lengths
up to 75 feet refer to Figure 6 for pipe size, and Figure 7 for
refrigerant adjustment.
On applications where liquid fioodback to the compressor
is likely to occur, use of a crankcase heater is recom-
mended.

Electrical Wiring
Electrical Shock Hazard.
Shut off electric power at fuse box or service pan-
el before making any electrical connections.
Failure to shut off electric power can result in,
property damage, personal injury and/or death.
The supply voltage should be 208-230 volts (196 volt mini-
mum to 253 volts maximum) 60Hz single phase.
APPROVED FOR USE WITH COPPER CONDUCTORS
ONLY. DO NOT USE ALUMINUM WIRE.
REFER TO UNIT RATING PLATE FOR CIRCUIT
PROTECTION.
Grounding
Permanently ground unit in accordance with the National
Electrical Code and local codes or ordinances. Use a cop-
per conductor of the correct size from the grounding termi-
nal in control box to a grounded connection in the service
panel or a properly driven and electrically grounded ground
rod.
Wiring Connections
Route Low Voltage wiring through entrance into area sep-
erated by insulating paper and make ALL low voltage con-
nections to the low voltage pigtails in this area. (Two Yellow
wires, AC or W,Y,O,BL, & R for HP). The pigtail wires have
600V insulation meeting approval for use in high voltage
areas.
See Figures 8 thru 11 and Wiring Diagram on unit.
Use of Rigid Metal Conduit
It is recommended that wires be tied together or twisted to-
gether inside the conduit. This will minimize any buzzing
type sounds that could be produced with high current
loads, such as during starting. Under some conditions it
may be necessary to use a hard start kit to eliminate prob-
lem noises.
Control Box Access
Remove the four screws. Cover is notched so it will slide
out from under top edge of unit.

Start- Up Procedure
Start-up Procedure
1. Close electrical disconnects to energize system.
2. Energize crankcase heater on units so equipped.
3. Set Thermostat selector switch to OFF.
4. Set room thermostat at desired temperature. Be sure
setpoint is below indoor ambient temperature for cooling
and above indoor ambient for heating.
5. Set the system switch of the thermostat on COOL and
fan switch for continuous operation or AUTO, as desired.
Operate unit for 15-20 minutes, then check the system re-
frigerant charge if it was necessary to adjust.
6. After the refrigerant charge has been adjusted, the sys-
tem is now ready for continuous operation.
Final Refrigeration Charge Adjustment
Some matching coils may need more refrigerant than the
factory charge. For optimum heat pump performance at
ARI test conditions, the system should initially be charged
per cooling mode instructions (ARI "B" test conditions). A
check in heating mode (ARI "High Heat" test conditions)
should then be performed. Charge level may be adjusted
per Heating Mode Charge instructions to ensure that high
heat capacity is at or above 95% of ARI rating. ARI cooling
tests may then be performed using the adjusted operating
charge.
Airflow
Before any adjustment is made to the refrigerant charge, it
is imperative that the air flow characteristics of the indoor
blower be established.
When checking indoor air flow, it is important to remember
that the blower will deliver a higher quantity of air across a
dry coil versus a wet coil. Blower charts are calculated with
a dry coil.
Recommended air flow for installations of cooling units and
heat pumps is 350-450 CFM per ton (12,000 BTUH)
through a wet coil. Refer to indoor unit installation instruc-
tions for proper methods of determining air flow and blower
performance.
To Check System Refrigerant Charge
(Superheat Method), Cooling Only
1. Attach an accurate temperature sensing device to the
suction line approximately 4" - 6" away from the suction
line service valve. The temperature sensing device should
be clamped securely to the suction line, on a horizontal
plane (between 9 & 3 O'clock) and insulated. Record the
suction line temperature.
2. Measure and record the suction line refrigeration pres-
sure. (Measure at the suction line service valve gauge
port.) Using Temperature /Pressure Chart convert this
pressure to the saturation refrigerant temperature. The dif-
ference between actual and saturated temperatures is the
amount of superheat.

Ifthe actual superheat readings are higher than shown, the
system is most likely under-charged, and charge should
be added. Add charge in 4 ounce increments, and recalcu-
late superheat values. Continue adjusting charge until the
actual superheat approximately matches the recom-
mended values.
Ifthe actual superheat readings are lower than shown, the
system is most likely over-charged, and charge should be
removed. Remove charge in 4 to 6 ounce increments, and
recalculate superheat values. Continue adjusting charge
until the actual superheat approximately matches the rec-
ommended values.
NOTE: Each time that charge is added or removed from
the system, allow the system to run approximately 15 min-
utes before pressure and temperature readings are taken
and superheat calculations made.
NOTE: Indoor Wet Bulb Temperature ( and Relative Hu-
midity) will alter superheat values. All readings should be
at 50% humidity inside and 350 to 450 CFM per ton across
the indoor coil.
Heating Checkout (Heat Pump Only)
1. Turn thermostat heat-cool switch to OFF. Turn ther-
mostat fan switch to AUTO.
2. Turn on all power except 230 volt line to outdoor sec-
tion.
3. Turn fan switch on thermostat to ON. Blower should
run. Reset to AUTO; blower should turn off.
4. Set thermostat below room temperature. Turn selec-
tor switch to heat. Move thermostat above room tem-
perature. Blower should run on heating speed and a
click should be heard in the condensing unit outside
(contactor closing). The sequencer coils for auxiliary
heat should be energized. After approximately 30
seconds the contacts in the sequencers should close
and the electric heat elements start heating. Allow 3
minutes for all heaters to come on.
5. Set system switch to OFF> Turn the thermostat
above room temperature. Turn on the 230 volt power
to the outdoor unit. Nothing apparent will be happen-
ing, but the crankcase heater is now energized. If the
outdoor temperature is below 75 °F allow the unit to
stay in this mode at least 6 hours. This is needed to
vaporize any refrigerant that may be in the compres-
sor oil.
6. Set the thermostat above room temperature. Move
system switch to heat. Count to 5 (about 5 seconds).
Turn the electric power off at the condensing unit dis-
connect switch. Check that there is no clattering or
unusual noises. The outdoor fan blade should have
started turning and a humming noise should have
been heard from the compressor. The indoor fan
should continue to run at its normal speed and elec-
tric elements continue to heat.
7. Wait 2 minutes, then repeat the procedure and re-
check the same things in case you missed something
during the first power application.
.With the unit operating, close all doors, windows,
storm windows, and openings to the house. Set the
thermostat to the desired setting. Set outdoor ther-
mostat (if installed) to balance point of house. If tem-
perature of house is at least two degrees below
thermostat setting, heat pump and auxiliary heat not
controlled by outdoor thermostats will continue to run
until room temperature is approximately 2° below
thermostat set point. Auxiliary heat light should go
out and auxiliary heat cycle off. Heat pump should
continue to run until thermostat reaches set point.
To Check System Refrigerant Charge
(Heating Mode)
For models with an outdoor restrictor orifice, optimum heat-
ing performance will be achieved when the operating
charge produces 10° - 20° F suction superheat at com-
pressor with 47° F outdoor ambient and 70° F dry bulb in-
door temperature (ARI "High Heat" test conditions) at rated
airflow.
The recommended method of addition or removal of
charge in the heating mode is by weight. The system op-
eration may be checked against the performance charts.
Remember, indoor airflow must be approximately 400
CFM per ton to compare operation to performance charts.
Defrost System (Heat Pump Only)
The defrost system is electronic with an adjustable time in-
terval of 90, 60, or 30 minutes. It is factory set at 60 or 90
minutes. At the selected time interval with the outdoor coil
temperature at approximately 28 °F, the system will de-
frost. When the sensor sees a rise in the outdoor coil tem-
perature to approximately 10 minutes, the defrost will be
terminated.
In some areas, with high humidity, the time interval may re-
quire adjustment for complete removal of ice from the coil.
For best economy, always set to the longest interval that
will keep the coil clear of ice.
NOTE: The term ice means hard but not frost. During nor-
mal operation, the coils may become coated with frost until
they are solid white. The time interval for the defrost should
be set so the frost and ice melt off completely without hard
ice building up on the coil.

Electrical Shock Hazard.
Shut off electric power at fuse box or service pan-
el before making any electrical connections.
Failure to shut off electric power can result in,
property damage, personal injury and/or death.
Defrost Control
Time Interval Adjustment
(Except Demand Defrost)
To adjust defrost frequency, turn off all power to the Heat
Pump. Remove control box cover and locate the electronic
defrost control board.
The defrost control board has a jumper clip that fits over
two pins. To change the time interval, remove the jumper
clip and place it on pins for the desired time interval, 30, 60
or 90 minutes.
Figure14 J Adjusting Defrost Time
During the cooling season check at least monthly for free
flow of drainage and clean if necessary.
Cleanliness
These tips will help you keep your air conditioner looking
better and working more efficiently:
1. Free air flow is essential. Keep the outdoor coil clean
and free of restrictions. Keep fences, shrubs, snow
drifts and any other obstructions at least two feet from
all coil air inlets.
2. Keep the coil free of grass clippings, weeds and other
debris. BE SURE TO TURN OFF ELECTRICITY BE-
FORE CLEANING!
4.
Coils may require cleaning. The coil should al-
ways be cold when cleaning. Use an alkaline
based cleaner only. Cleaning a hot coil or using
an acid based cleaner will remove the paint from
the fins and may clog the coil.
Never use a weather cover over the outdoor unit un-
less it is a ventilated type or made of breathable fabric
that will allow moisture to evaporate rapidly. A cover
that holds moisture in the unit will cause more rust
build-up and damage than normal exposure to
weather.
