C. ACCUTRON TM FLOW CONTROL VALVE 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.
c_ IM
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.

INSTALLER'S GUIDE
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.
HEAT SHIELD
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.

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 a distinct 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.
A WARNING: When installing or servicing
this equipment, ALWAYS exercise basic safety precau- tions to avoid the possibility of electric shock.
A CAUTION : Threephasescrollcompressors
will run in reverse if powered up with improper phasing.

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 12hours 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 d the 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.
