If the indoor unit Syste In Refi'i_ erant F1ow control is an Accu tron-

orifice and check valve assembly, an orifice size change will be

necessary.

The outdoor model determines the required orifice size. Check

the listed orifice size on nameplate of the selected outdoor model.

If the indoor u nit is factory shipped with a dilIbrent orifice size,

the orifice must be changed to obtain system rated performance.

IMPORTANT: The outdoor u nit is shipped with the proper size

orifice and a stick-on orifice size label in an envelope attached

to the outdoor unit. Outdoor unit nameplate will have correct

orifice size specified as BAYFCCV - - - A fbr rated performance.

D. INSTALLING REFRIGERANT LINES

Condensing units have provisions for braze connections.

Pressure taps are provided on the service valves of outdoor unit

fbr compressor suction and liquid pressures.

The indoor end of the recommended refrigerant line sets may be

straight or with a 90 degree bend, depending upon situation

requirements. This should be thoroughly checked out before

ordering refl'igerant line sets.

The gas line must always be insulated.

The units are factory charged with the system charge required

when using fif_een (15) feet of connecting line. Unit nameplate

charge is the same.

Final refrigerant charge adjustment is necessary. Use the Charg-

ing (?harts in the outdoor unit Service Facts.

1. Determine the most practical way to run the lines.

2. Consider types of bends to be made and space limitations.

NOTE: Large diameter tubing will be very di[f_cult to rebend once

it has been shaped.

3. Determine the best starting point fbr routing the refl_igerant

tubing- -INSIDE OR OUTSIDE THE STRUCTURE.

4. Provide a pull-thru hole of suflicient size to allow both liquid

and gas lines. The location of this hole (if practical) should be just

above the wall plate which is resting on the foundation.

5. Be sure the tubing is of sufficient length.

6. Uncoil the tubing --- do not kink or dent.

7. Route the tubing maMng all required bends and properly

secure the tubing before making connections.

8. To prevent a noise within the building structure due to

vibration transmission fl_oln the refrigerant lines, the following

precautions should be taken:

a. When the refl'igerant lines have to be fastened to floor

joists or other fl'aming in a structure, use isolation type hangers.

b. Isolation hangers should also be used when refrigerant

lines are run in stud spaces or enclosed ceilings.

c. Where the refrigerant lines ru n through a wall or sill, they

should be insulated and isolated.

d. Isolate the lines fl'om all ductwork.

E. SERVICE VALVE OPERATION

BRASS LIQUID LINE SERVICE VALVE

The Brass Liquid Line Service Valve is factory shipped in the

seated position to hold factory charge. The pressure tap service

port (when depressed) opens only to the field brazing side of the

valve when the valve is in the seated position. The liquid line

valve is not a back seating valve (see WARNING below).

WARNING: Extremecautionshouldbeex-

ercisedso the internal steel stem retaining ring is not

damaged by backing out the valve stem when opening the

valve. If the valve stem is forced out past the retaining

ring, system pressure could force the valve stem out of the

valve body. If the retaining ring is missing, do not attempt

to open the valve. See Figure 3.

BRASS GAS LINE SERVICE VALVE

The Brass Gas Line Service Valve is shipped in the closed

position to hold the factory refl'igerant charge. The pressure tap

service port (when depressed) opens only to the field brazing side

when the valve is in the closed position.

BRAZING REFRIGERANT LINES

1. Before brazing, remove plugs from external copper stub

tubes. Clean internal and external surfaces of stub tubes prior

to brazing.

2. Cut and fit tubing minimizing the use of sharp 90 ° bends.

3. Insulate the entire gas line and its fittings.

4. Do NOT allow uninsulated liquid line to come in direct

contact with bare gas line.

5. Precautions should be taken to avoid heat damage to

the pressure tap valve core during brazing. It is recom-

mended that the pressure tap port valve core he removed

and a wet rag wrapped around the valve body.

CAUTION: Use care to make sure that no

moisture enters pressure tap port, while wet rag is being

used.

6. Remove braze shield from clear plastic bag. Soak pad in

water and place over suction and liquid lines to protect unit

finish. See Figure 5. Discard pad when finished with brazing.

7. Use a Dry Nitrogen Purge and Brazing Alloy without flux

when brazing the field line to the copper factory connection. Flow

dry nitrogen into either valve pressure tap port, thru the tubing

and out the other port while brazing.

8. Braze using accepted good brazing techniques.

LEAK CHECK

CAUTION :In scrollcompressorapplications,

dome temperatures may be hot. Do not touch top of com-

pressor, may cause minor to severe burning.

IMPORTANT: Replace pressure tap port valve core be-

fore attaching hoses for evacuation.

After the brazing operation of refrigerant lines to both the

outdoor and indoor unit is completed, the field brazed connec-

tions must be checked fbr leaks. Pressurize through the service

valve ports, the indoor unit and field refl_igerant lines with dry

nitrogen to 200 psi. Use soap bubbles or other leak-checking

methods to see that all field joints are leak-fl'ee! If not, release

pressure; then repair!

SYSTEM EVACUATION

NOTE: Since the outdoor unit has a refrigerant charge, the gas

and liquid line valves must remain closed.

1. Upon colnpletion ofleak check, evacu ate the refrigerant lines

and indoor coil befbre opening the gas and liquid line valves.

2. Attach appropriate hoses froJn manififld gauge to gas and

liquid line pressure taps.

NOTE: Unnecessary switching of hoses can be avoided and

complete evacuation of'all lines leading to sealed system can be

accomplished with mani[bld center hose and connecting branch

hose to a qylinder of HCFC-22 and vacuum pump.

3. Attach center hose of manifbld gauges to vacuum pump.

4. Evacuate until the micron gauge reads no higher than

350 microns.

5. Close off valve to vacuum pump and observe the micron

gauge. Ifgaugepressurerisesabove 500micronsinone (1) minute,

then evacuation is incomplete or system has a leak.

6. If vacuum gauge does not rise above 500 microns in one (1)

minute, the evacuation should be complete.

7. With vacuum pump and micron gauge blanked off, open valve

on HCFC-22 cylinder and charge rel?igerant lines and indoor

coil with vapor to tank pressure of HCFC-22 supply.

NOTE: DO NOT VENT REFRIGERANT INTO THE

ATMOSPHERE.

8. Close valve on HCFC-22 supply cylinder. Close valves on

manifold gauge set and remove refrigerant charging hoses from

liquid and gas pressure tap ports.

NOTE: A 3/16" Allen wrench is required to open liquid line

service valve. A 1/4" Open End or Adjustable wrench is required

to open gas line valve. A 3/4" Open End wrench is required to take

off the valve stem cap.

9. The liquid line shut-off valve can now be opened. Remove

shut-off valve cap. Fully insert hex wrench into the stein and

backout counterclockwise until valve stem just touches retainer

ring (approximately five (5) turns) observing WARNING state-

ment on page 2. See Figure 3.

10. Replace liquid service pressure tap port cap and valve stein

cap. These caps MUST BE REPLACED to prevent leaks.

Replace valve stem and pressure tap cap finger tight, then

tighten an additional 1/6 turn.

11. The gas valve can now be opened. Open the gas valve by

removing the shut-off valve cap and turning the valve stem

1/4 turn counterclockwise, using 1/4" Open End or Adjustable

wrench. See Figure 4.

12. The gas valve is now open fbr refrigerant flow. Replace valve

stem cap to prevent leaks. See Figure 4.

If refrigerant lines are longer than 25 feet and/or a different size

than recommended, it will be necessary to adjust system refrig-

erant charge upon completion of installation.

F. ELECTRICAL CONNECTIONS

CAUTION : Threephasescrollcompressors

will run in reverse if powered up with improper phasing.

If the compressor is running backwards there will be

little or no difference in suction and discharge pressure

and it will make adistinct louder sound. Reversing any

two of the field installed power leads will correct the

compressor rotation. Failure to change the power leads to

correct compressor rotation may result in compressor

damage during operation.

AWARNING: When installing or servicing

this equipment, ALWAYS exercise basic safety precau-

tions to avoid the possibility of electric shock.

ACAUTION : Threephasescrollcompressors

will run in reverse if powered up with improper phasing.

1. Power wiring and grounding of equipment mu st comply with

local codes.

2. Power supply must agree with equipment nameplate.

3. Install a separate disconnect switch at the outdoor unit.

4. Ground the outdoor unit per local code requirements.

5. Provide flexible electrical conduit whenever vibration trans-

mission may create a noise problem within the structure.

6. The use of color coded low voltage wire is recommended to

simplify connections between the outdoor unit, the thermostat

and the indoor unit.

following list:

1. Refrigerant Line, Leak checked .......................................................................................................... [ ]

2. Suction Lines and Fittings properly insulated ...................................................................................... [ ]

3. Have all Refrigerant Lines been secured and isolated properly? ........................................................ [ ]

4. Have passages through masonry been sealed? If mortar is used, prevent mortar from

coming into direct contact with copper tubing ..................................................................................... [ ]

5. Indoor coil drain line drains freely. Pour water into drain pan ............................................................. [ ]

6. Supply registers and return grilles open and unobstructed ................................................................. [ ]

7. Return air filter installed ...................................................................................................................... [ ]

8. Thermostat thermometer is accurate. Check against a reliable thermometer. Adjust

per instructions with thermostat .......................................................................................................... [ ]

9. Is correct speed tap being used? (Indoor blower motor) .................................................................... [ ]

SYSTEM OPERATIONAL CHECK

IMPORTANT: To prevent compressor damage which may result from the presence of LIQUID refrigerant in the

crankcase, these procedures should be followed at initial Start-Up and at anytime the power has been offfor 12 hours

or more.

1. Before proceeding with this "Operational Check," go to "Compressor Sump Heat Section" of this instruction to

determine the time compressor heat has been "ON," and make entry dthe designated lines, in Step 2.

2. Start-Up Time A.M./P.M. Power Applied Time A.M./P.M.

Time Lapse Hours Minutes.

3. If Steps 1 and 2 cannot be used, then place thermostat's system switch in the "OFF" position and apply power

by closing system disconnect switch. This energizes compressor heat and evaporates the liquid in the

crankcase. TO EVAPORATE LIQUID ALLOW AT LEAST ONE-HALF HOUR PER POUND (HCFC-22), AS

SHOWN ON UNIT NAMEPLATE.

OPERATING PRESSURES: After the unit has operated in the cooling mode for a short period of time, install

pressure gauges on the gauge ports of the discharge and suction line valves. Check the suction and discharge

pressures and compare them to the normal operating pressures provided in the unit's Service Facts.

NOTE: Use the pressures from Service Facts to determine the unit refrigerant charge.

To charge the system accurately, use superheat charging, or pressures

depending on flow control.

4. Except as required for safety while servicing: DO NOT OPEN SYSTEM DISCONNECT SWITCH.

SUPPLEMENTARY HEATERS CHECKOUT PROCEDURES, IF USED

DOES HEATER REQUIRE A SEPARATE CIRCUIT?

1. Be sure the fused disconnect switch is "OFF," and safety label (if any) is attached ................................ [ ]

2. Check on field wiring for sound connections and grounding according to codes .................................... [ ]

3. Check fuses for proper size per nameplate specifications ..................................................................... [ ]

4. Check control box panel -- in place and secured .................................................................................. [ ]
