platforms, and other issues.
Locate unit away from fresh air intakes, vents, or bedroom

windows. Noise may carry into the openings and disturb people
inside.

Locate unit in a well drained area, or support unit high enough so
that water runoff will not enter the unit.

Locate unit away from areas where heat, lint, or exhaust fumes will
be discharged onto unit (as from dryer vents).

Locate unit away from recessed or confined areas where
recirculation of discharge air may occur (refer to CLEARANCE

REQUIREMENT section of this document).
Roof-top installation is acceptable providing the roof will support

the unit and provisions are made for water drainage and
noise/vibration dampening.

NOTE: Roof mounted units exposed to wind may require wind
baffles. Consult the manufacturer for additional information.

CLEARANCE REQUIREMENTS

When installing, allow sufficient space for airflow clearance, wiring,
refrigerant piping, and service.

Allow 24 in. (609.6 mm) clearance to service end of unit and 48 in.
(1219.2 mm) (above unit. For proper airflow, a 6-in. (152.4 mm)
clearance on 1 side of unit and 12-in. (304.8 mm) on all remaining
sides must be maintained. Maintain a distance of 24 in. (609.6 mm)
between units or 18 in. (45%2 mm) if no overhang within 12 ft. (3.66
m).

Position so water, snow, or ice from roof or eaves cannot fall directly
on unit.

NOTE: 18" (457.2 mm) clearance option described above is

approved for outdoor units with wire grille coil guard only. Units

with louver panels require 24" (609.6 mm) between units. On
rooftop applications, locate unit at least 6 in. (152.4 mm) above

roof surface.

EXPLOSION HAZARD

Failure to follow this warning could
result in death, serious personal iniury,
and/or property damage.

Never use air or gases containing
oxygen for leak testing or operating
refrigerant compressors. Pressurized
mixtures of air or gases containing
oxygen can lead to an explosion.

UNIT SUPPORT

NOTE: Unit nmst be level _+ 2 degrees {3/8 inch rise or fall per
foot of run (10 mm rise or fall per 305 mm of run) } or compressor
may not function properly.

A. GROUND LEVEL INSTALLATION

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. Soil conditions must be considered so that the

platform or pad does not shift or settle and leave the unit partially
supported. Minimum pad dimensions are shown in Fig. 1.

If beams or an open platform are used for support, it is
recommended that the soil be treated or area be graveled to reduce

the growth of grasses and weeds.
To minimize vibration or noise transmission, it is recommended

that supports not be in contact with the building structure.
However, slabs on grade constructions with an extended pad are

normally acceptable.

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 fiat roof, locate unit minimum 6 inches (152
ram) above roof level.

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 several load bearing walls. These suggestions are to

minimize noise and vibration transmission through the structure. If
the structure is a home or apartment, avoid locating the unit over

bedrooms or study.
NOTE: When 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.

C. FASTENING UNIT DOWN

If conditions or local codes require the unit be attached in place,
remove the knockouts in the base pan and install tie down bolts

through the holes (see Fig. 1).
Contact local distributor for hurricane hold-down details and the

P.E. (Professional Engineer) certification, when required.

REFRIGERATION SYSTEM

EXPLOSION AND FIRE HAZARD

Failure to follow this caution could result in property
damage, personal iniury and/or death.

This unit utilizes R-22 refrigerant. Use only R-22
refrigerant when servicing this unit.

DO NOT, under any circumstances, use R-410A
refrigerant in this system.

PROPERTY DAMAGE HAZARD
Failure to follow this caution may result in property

damage.
Inadequate unit support may cause excessive vibration,

noise, and/or stress on the refrigerant lines, leading to
refrigerant line failure.

A. COMPONENT MATCHES

Check to see that the proper system components are in place,

especially the indoor coil.
R-22 outdoor units can only be used with R-22 specific indoor

coils. If there is a refrigerant ntis-match, consult the indoor coil
manufacturer to deternfine if a refrigerant conversion kit is

available for the indoor coil.

This outdoor unit is designed for use only with indoor coils that
utilize a TXV refrigerant metering device. If any other type of

metering device is installed on the indoor coil, consult the indoor
coil manufacturer to deternfine if a TXV conversion kit is available

The compressors for these units are supplied with Polyol Ester
(POE) Oil. If the existing line set and indoor coil has residual

nfineral oil (MO) there is no concern with percentage of oil
nfixtures as both are nfiscible with the R-22. Mixtures of both oils

at any percentage will lubricate and return with the R-22.

B. REFRIGERANT LINE SETS

The refrigerant line set must be properly sized to assure maximum
efficiency and proper oil circulation.

Refer to Long Line Guideline for line set sizing.
NOTE: Total line set length must not exceed 200 feet (61 m).
A crankcase heater must be used when the refrigerant line length

exceeds 80 feet (24.4 m).
If vertical separation between indoor and outdoor units is greater

than 30 ft (9.14 m), refer to the Long Line Guideline.
If it is necessary to add refrigerant line in the field, use dehydrated

or dry, sealed, deoxidized, copper refrigeration tubing. Do not use
copper water pipe.

Do not remove rubber plugs or caps from copper tubing until
connections are ready to be made.

Be extra careful when bending refrigeration tubing. Tubing can
"kink" easily, and if this occurs, the entire length of tubing must be

replaced.

UNIT OPERATION HAZARD
Failure to follow this caution may result in improper unit

operation.
Do not leave system open to atmosphere any longer than

absolutely required for installation. Internal system
components - especially refrigerant oils - are extremely
susceptible to moisture contamination. Keep ends of tubing
sealed during installation until the last possible moment.

C. ROUTING AND SUSPENDING REFRIGERANT LINES

Run refrigerant lines as straight and direct as possible, avoiding
unnecessary bends and turns. Always insulate the entire suction
line. Both lines should be insulated when routed through an attic or

when routed through an underground raceway.
When routing refrigerant lines through a foundation or wall, do not

allow refrigerant lines to come in direct contact with the building

structure.
Make openings large enough so that lines can be wrapped with

extra insulation. Fill all gaps with RTV caulk. This will prevent
noise transmission between the tubing and the foundation or wall.

Along floor or ceiling joists, suspend refrigerant lines so that they
do not contact the building structure, water pipes, or ductwork. Use

insulated or suspension type hangers. Metal straps must be at least

1" (25 mm) wide to avoid cutting into the tube insulation. Keep the

liquid and suction lines separate. Refer to Fig. 3.

PERSONAL INJURY HAZARD
Failure to follow this warning could result in personal iniury

and/or death.

Relieve pressure and recover all refrigerant before servicing
existing equipment, and before final unit disposal. Use all
service ports and open all flow-control devices, including

solenoid valves.

UNIT OPERATION HAZARD
Failure to follow this caution may result in improper

product operation.
Do not bury more than 36" (1 m) of line set underground.

Refrigerant may migrate to cooler buried section during
extended periods of unit shut-down, causing refrigerant
slugging and possible compressor damage at start-up.

If ANY section of the line set is buried underground,
provide a minimum 6" (152 mm) vertical rise at the service

valve.

E. LIQUID LINE FILTER-DRIER

NOTE: It is required that an approved filter drier (XH-6 with
25% activated alumina / 75% molecular sieve desiccants) be

installed in the liquid line due to the POE oil.
Leave the plugs in the tube ends until the filter-drier is installed.

The optimal location for the filter-drier is close to the indoor coil.
Install the filter-drier with the arrow pointing towards the indoor
coil. Refer to Fig. 4.

FIRE HAZARD

Failure to follow this warning could result in personal injury,
death, and/or property damage.

Refrigerant and oil mixture could ignite and burn as it
escapes and contacts brazing torch. Make sure the refrigerant
charge is properly removed from both the high and low sides
of the system before brazing any component or lines.

Clean line set tube ends with emery cloth or steel brush. Remove
any grit or debris.

Insert line set tube ends into service valve tube stubs.
Apply heat absorbing paste or heat sink product between service

valve and joint. Wrap service valves with a heat sinking material
such as a wet cloth.

Braze joints using a Sil-Fos or Phos-copper alloy.

UNIT DAMAGE HAZARD

Failure to follow this caution may result in unit component
damage.
Service valves must be wrapped while brazing in a heat

sink material, such as a wet cloth.

F. SERVICE VALVES

Service valves are closed and tube stubs are plugged from the
factory. Outdoor units are shipped with a dry nitrogen holding

charge sealed in the unit. Leave the service valves closed until all
other refrigerant system work is complete or the charge will be

lost. Leave the plugs in place until line set tubing is ready to be
inserted.

Service valve bodies are brass and tube stubs are copper.

G. BRAZING CONNECTIONS

NOTE: Remove valve core from schrader port on both Service
Valves BEFORE brazing. This helps prevent overheating and

damage to valve seals (refer to Fig. 5). Replace valve core when
brazing is completed.

CORE

Fig. 5 - Service Valve

H. OPENING SERVICE VALVES

Outdoor units are shipped with a dry nitrogen holding charge

sealed in the unit. Opening the service valves releases this charge
into the system.

NOTE: Open the Suction service valve first. If the Liquid service
valve is opened first, oil from the compressor may be drawn into
the indoor coil TXV, restricting refrigerant flow and affecting
operation of the system.

Remove Suction service valve cap and insert a hex wrench into the
valve stem. Hold the valve body steady with an end-wrench and

back out the stem by turning the hex wrench counterclockwise.
Turn the stem until it just contacts the rolled lip of the valve body.

After the nitrogen charge has bled into the system, open the Liquid
service valve.

NOTE: These are not back-seating valves. It is not necessary to
force the stem tightly against the rolled lip.

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 surface on inside of cap.

Tighten cap finger tight and then tighten additional 1/6 of a turn (1
wrench flat) to properly seat the sealing surfaces.

INDOORCOIL

PRODUCT DAMAGE HAZARD
Failure to follow this caution may result in product damage.

Never use the outdoor unit compressor as a vacuum pump.
Doing so may damage the compressor.

Condenser, line set, and indoor coil should be evacuated using the
recommended deep vacuum method of 500 microns. If deep

vacuum equipment is not available, the alternate triple evacuation
method may be used by following the specified procedure.

If vacuum must be interrupted during the evacuation procedure,
always break vacuum with dry nitrogen.

UNIT OPERATION HAZARD
Failure to follow this caution may result in improper unit

operation..
This unit is filled with a Nitrogen charge. Prior to starting

this unit, evacuate to 500 microns and charge with
refrigerant listed on rating label. Purge nitrogen before
connection to vacuum pump.

Deep Vacuum Method
The deep vacuum method requires a vacuum pump capable of

pulling a vacuum to 500 microns and a vacuum gauge capable of
accurately measuring this vacuum level. The deep vacuum method

is the most positive way of assuring a system is free of air and
water.

Watch the vacuum gauge as the system is pulling down. The
response of the gauge is an indicator of the condition of the system

(refer to Fig. 6).
With no leaks in the system, allow the vacuum pump to run for 30

minutes minimum at the deep vacuum level.

Triple Evacuation Method
The triple evacuation method should only be used when system

does not contain any water in liquid form and vacuum pump is
only capable of pulling down to 28 inches of mercury (711 mm
Hg). Refer to Fig. 8 and proceed is as follows:

1. Pull system down to 28 inches of mercury (711 mm Hg)
and allow pump to continue operating for an additional 15

minutes.

2. Close manifold valves or valve at vacuum pump and shut
off vacuum pump.

3. Connect a nitrogen cylinder and regulator to system and fill

with nitrogen until system pressure is 2 psig.

4. Close nitrogen valve and allow system to stand for 1 hour.
During this time, dry nitrogen will diffuse throughout the
system absorbing moisture.

5. Repeat this procedure as indicated in Fig. 7.

6. After the final evacuate sequence, confirm there are no leaks
in the system. If a leak is found, repeat the entire process

after repair is made.

START-UP PROCEDURE

1. Set indoor thermostat selector switch to OFF.

2. Turn ON all electrical disconnect devices.

3. If unit has a crankcase heater, energize the heater and wait

24 hours before proceeding.

4. Set indoor thermostat at desired temperature. Be sure set-

point is below indoor ambient temperature or thermostat
will not call for cooling.

5. Set indoor thermostat selector switch to COOL. Operate

unit for minimum 15 nfinutes, then check system refrigerant
charge.

REFRIGERANT CHARGE

Table 1 shows the suggested refrigerant charge quantities for a 15
foot (4.6 m) lineset. If shorter or longer refrigerant lines or a

different indoor coil are used, the charge will have to be adjusted.
For different line lengths, add or remove charge based on 0.6

ounces (17 g) charge per foot (305 ram) of difference. For
example, a 25 foot (7.6 m) line set is 10 feet (3 m) longer than the

specified 15 feet (4.6 m). Add 0.6 ounces (17 g) charge for each of
the extra 10 feet (3 m):

10 x 0.6 = 6.0 ounces additional charge
(3 m x 17 g = 51 g additional charge)

The initial charge should be weighed into the system per Table 1
and the additional amount for the length of line set. Then check

subcooling.
This outdoor unit is designed for use only with indoor coils that

utilize a TXV refrigerant metering device. With an indoor TXV,
use the subcooling method to make final charge adjustments:

NOTE: Only use subcooling charging method when the following
is true:

• outdoor ambient temperature is between 70°F and 100°F

(21°C and 38°C)

• indoor temperature is between 70 ° and 80°F
(21 °C and 27°C)

• line set is less than 80 feet (24.4 m).

1. Operate unit a minimum of 15 nfinutes before checking
charge.

NOTE: If outdoor unit has a 2-speed fan motor, motor will
operate in low speed when outdoor ambient temperature is

below 82°F (28°C). Pull one of the yellow low voltage
wires off the fan control and the unit will default to high

speed fan for servicing. Reconnect wire after servicing.

2. Measure liquid service valve pressure by attaching an
accurate gauge to service port.

3. Measure liquid line temperature by attaching an accurate
thernfistor type sensor or electronic thermometer to liquid

line near outdoor coil.

4. Refer to unit rating plate for required subcooling temperat-
ure.

5. Refer to Table 2. Find the required liquid line temperature

where the rating plate subcooling temperature intersects

measured liquid service valve pressure.

6. If the measured liquid line temperature is higher than the
chart number, add refrigerant to lower the measured temper-

ature.
NOTE: When adding refrigerant, charge in liquid form,
using a flow restricting device, into the suction port.

If the measured liquid line temperature is lower than the
chart number, reclaim refrigerant to raise the measured

temperature.
Tolerance is _+3 °F (_+ 1.7 °C).

SEQUENCE OF OPERATION

With power supplied to indoor and outdoor units, transformer is
energized.

On a call for cooling, the thermostat makes circuits R-Y and R-G.
Circuit R-Y energizes contactor, starting outdoor fan motor and
compressor. Circuit R-G energizes indoor unit blower relay,

starting indoor blower motor.
When thermostat is satisfied, its contacts open, de-energizing

contactor and blower relay. Compressor and motors stop.
NOTE: If indoor unit is equipped with a time-delay relay circuit,

the blower runs an additional length of time to increase system
efficiency.

MAINTENANCE

Condensate Drain

During the cooling season, check monthly for free flow of drainage

and clean if necessary.
Cleanliness

These tips will help keep the air conditioner looking better and
working more efficiently:

1. Free flow of air is essential. Keep fences, shrubs, trash cans,
and other obstructions at least 18 inches (0.5 m) from all

coil inlets.

2. Keep the coil free of grass clippings, leaves, weeds, and
other debris.

NOTE: Coil may occasionally require cleaning with a
liquid solution. The coil nmst 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.

3. Never use a weather cover over the outdoor unit unless 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.
