GENERAL

NOTICE: These outdoor units may be used with indoor

units equipped with Capillary Tube, Thermostatic

Expansion Valve or the Accutron TM Flow Control Check

Valve (F.C.C.V.) assembly for refrigerant flow control.

Check lbr transportation damage alter unit is uncrated. Report

promptly, to the carrier, any damage found to the unit.

To determine the electrical power requirements of the u nit, refer

to the nameplate of the unit. The electrical power available must

agree with that listed on the nameplate.

B. LOCATION & PREPARATION OF THE UNIT

1. The unit should be set on a level support pad at least as large

as the unit base pan.

2. The support pad must NOT be in direct contact with any

structure. The unit must be positioned a minimum of 12" Ii'om

any wall or surrounding shrubbery to insure adequ ate airflow. A

30" clearance must be provided in front of control box (access

panels) & any other side requiring service access to meet

National Electrical Code. The unit must be lar enough away

from any structure to prevent excess roof run-off water from

pouring directly on the unit.

3. The top discharge area must be unrestricted for at least five

(5) feet above the unit.

4. When the outdoor unit is mounted on a roof, be sure the roof

will support the unit's weight. Properly selected vibration

isolators are recommended to prevent transmission to the build-

ing structure.

5. The maximmn length of refrigerant lines from outdoor to

indoor unit should NOT exceed eighty (80) feet.

QTOP DISCHARGE --- UNRESTRICTED

5 FT. ABOVE UNIT

6. If the outdoor unit is mounted above the air handler, maxi-

mum lift should not exceed sixty (60) feet (suction line). If air

handler is mounted above the condensing unit, maximum lilt

should not exceed sixty (60) feet (liquid line).

INSTALLER'S GUIDE

C. ACCUTRON TM FLOW CONTROL VALVE

If the indoor unit System Refrigerant Flow control is an

Accutron TM orifice and check valve assembly, an orifice size

change may 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 different orifice size,

the orifice must be changed to obtain system rated performance.

IMPORTANT: The outdoor unit 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 for rated performance.

D. INSTALLING REFRIGERANT LINES

Condensing units have provisions lbr braze connections.

Pressure taps are provided on the service valves of outdoor unit

for compressor suction and liquid pressures.

The indoor end of 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 refrigerant line sets.

The gas line must always be insulated.

The units are Ihctory charged with the system charge required

when using twenty-five (25) feet of connecting line. Unit name-

plate charge is the same. If final refrigerant charge adjustment

is necessary, use the Charge Charts 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: Lasce diameter tubing will be very difficult to rebend once

it has been shaped.

3. Determine the best starting point Ibr routing the refrigerant

tubing--INSIDE OR OUTSIDE THE STRUCTURE.

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

and gas lines plus fittings to clear. The location of this hole (if

practical) should be just about the wall plate which is resting on

the Ibundation.

5. Be sure the tubing is of sufficient length.

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

7. Route the tubing making all required bends and properly

secure the tubing before making connections.

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

vibration transmission from the refrigerant lines, the following

precautions should be taken:

a. When the refrigerant lines have to be Ihstened to floor

joists or other framing 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 run through a wall or sill, they

should be insulated and isolated.

d. Isolate the lines from all ductwork.

OPERATION

The Service Valves are lhctory shipped in the seated position to

hold ihctory charge. The pressure tap service port (when de-

pressed) 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).

Extreme caution should be exercised so 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 BALL SERVICE VALVE

The Brass Gas Line Ball Service Valve is shipped in the closed

position to hold the factory refrigerant charge. The pressure tap

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

when the valve is in the closed position.

The Gas Line Service Valve is full open with a 1/4 turn counter-

clockwise. See Figure 4.

BRAZING REFRIGERANT LINES

1. Before brazing, remove plugs li'om 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 be removed

and a wet rag wrapped around the valve body.

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.

IMPORTANT: Replace pressure tap port valve core before

attaching hoses for evacuation.

After brazing operation of refrigerant lines to both the outdoor and

indoor unit is completed, the field brazed connections must be

checked fbr leaks. Pressmize through the service valve ports, the

indoor u nit and field refrigerant lines with dry nitrogen to 200 psi.

Use soap bubbles or other leak-checking methods to see that all

field joints are leak-free! If not, release pressure; then repair!

SYSTEM EVACUATION

NOTE: Since the outdoor unit has a re[?igerant charde, the gas and

liquid line vcllves must remain closed.

1. Upon completion of leak check, evacuate the refrigerant lines

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

2. Attach appropriate hoses from manifold gauge to gas and liquid

line pressure taps.

NOTE: Unnecessm'y switching of hoses can be avoided and

complete evacuation of all lines leading to sealed system can be

accomplished with manifold center hose and connecting branch

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

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

4. Evacuate until the micron gauge reads no higher than 350

microns.

5. Close offvalve to vacuum pump and observe the micron gauge.

If gauge pressure rises above 500 microns in one (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 a vacuum pump and micron gauge blm_ked off; open valve

on HCFC-22 cylinder and charge refrigerant 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. An Adjustable or 3 /4" Open End u._nch

is required to take aff 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 stem and

backou t cou nterclockwise until valve stem just tou ches retainer

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

ment. See Figure 3.

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

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. For a ball type gas valve,

open the valve by removing the shut-off valve cap and turning

the valve stein 1/4 turn counterclockwise. See Figure 4. For

brass gas line service valve opening, follow items 9 & 10 above.

See Figure 3.

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

stem cap to prevent leaks. See Figure 3 & 4.
