2TTB0530-536M & 2TTB0524-536AA

ALL phases of this installation must comply with NATIONAL, STATE AND LOCAL CODES

IMPORTANT -- This Document is customer property and is to remain with this unit. Please return to service information

pack upon completion of work.

These instructions do not cover all variations in

systems nor provide for every possible contingency to

be met in connection with installation. All phases of

this installation must comply with NATIONAL, STATE

AND LOCAL CODES. Should further information be

desired or should particular problems arise which are not

covered sufficiently for the purchaser's purposes, the matter

should be referred to your installing dealer or local distributor.

A. GENERAL

The following instructions cover 2TTB05; Condensing Units.

NOTE:

These outdoor units may be used with indoor units

equipped with Thermostatic Expansion Valve or Accutron rM

Flow Control Check Valve (E C.C.V.) assembly for refrigerant

flow control only.

Check for transportation damage after unit is uncrated.

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

To determine the electrical power requirements of the unit,

refer to the nameplate of the unit. The electrical power

available must agree with that listed on the nameplate.

B. LOCATION &PREPARATION OFTHE UNiT

1. When removing unit from the pallet, notice the tabs on

the basepan. Remove tabs by cutting with a sharp tool as

shown in Figure 2 (see page 2).

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

large as the unit base pan, such as a concrete slab. If this

is not the application used please refer to application

bulletin "Trane APB2001-02".

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

structure. Unit must be positioned a minimum of 12"

from any wall or surrounding shrubbery to insure

adequate airflow. Clearance must be provided in front of

control box (access panels) & any other side requiring

service access to meet National Electrical Code. Also,

the unit location must be far enough away from any

structure to prevent excess roof run-off water from

pouring directly on the unit. Do not locate unit(s) close to

bedroom(s).

4. The top discharge area must be unrestricted for at least

five (5) feet above the unit.

5 FT. ABOVE UNIT=UNRESTRICTED

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

roof will support the unit's weight. Properly selected

isolation is recommended to prevent sound or vibration

transmission to the building structure.

The maximum length of refrigerant lines from outdoor to

indoor unit should NOT exceed eighty (80) feet.

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

mum lift should not exceed sixty (60) fhet (suction line).

If air handler is mounted above condensing unit, maxi-

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

NOTE:

Refer to "Refrigerant Piping Software" Pub. No. 32=3312=02.

8. Locate and install indoor coil or air handler in accor-

dance with instruction included with that unit.

|nsta||er's Guide

C. ACCUTRON TM FLOW CONTROL VALVE

If the indoor unit System Refrigerant Flow control is an

Aceutron TM orifice and check valve assembly, an orifice size

change may be necessary. See Figure 3.

The outdoor model determines the required orifice size.

Check the listed orifice size on nameplate of the selected

outdoor model. If the indoor unit 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 un# nameplate will have correct orifice size

specified as BAYFCCV---A for rated performance.

D. INSTALLING REFRIGERANT LINES

Condensing units have provisions for flare connections.

Pressure taps are provided on the service valves of outdoor

unit for 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 refrigerant line sets.

The gas line must always be insulated.

The units are factory charged with the system charge

required when using fifteen (15) feet of connecting line. Unit

nameplate charge is the same.

Final refrigerant charge adjustment is necessary. Use

the Charging 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:

Large diameter tubing will be very difficult to rebend once it

has been shaped.

3. Determine the best starting point for routing the refriger-

ant tubing -- INSIDE OR OUTSIDE THE STRUCTURE.

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

liquid and gas lines.

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 fastened to floor

joists or other framing in a structure, use isolation

type hangers.

b. Isolation hangers should also be used -when refriger-

ant 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.

E. SERVICE VALVE OPERATION

BRASS LIQUID AND GAS LINE SERVICE VALVES

The Brass Liquid and Gas Line Service Valves are factory

shipped in the seated position to hold factory charge. The

pressure tap service port (when depressed) opens only to the

field side of the valve when the valve is in the seated posi-

tion. The liquid line valve is not a back seating valve (see

WARNING below).

Extreme caution should be exercised when opening the

Liquid Line Service Valve. Turn valve stem counterclock-

wise only until the stem contacts the rolled edge. (See

Figure 4) No torque is required.

FLARE FITTINGS

1. Remove gas and liquid line flare nuts from service

valves and discard copper caps.

Cut and fit tubing minimizing the use of sharp 90 degree

bends, for a even flare it is recommended that a tube

cutter be used. A hacksaw should not be used to cut the

tubing.

Remove any burrs from the inside edge of copper tubes

with a deburring tool or knife.

Place the flare nuts on copper tubes before flaring tube

ends. See Figure 5.

Flare the tube ends using a rotating flaring tool or

compression type. Tube flare cone and flare tool should

be well lubricated with refrigeration oil while it is being

formed.

6, Prior to assembling the flares, check the mating sur-

faces for the following:

a. Thinning of the flare tube material.

b. Cracked or split tube.

c. Scoring or longitudinal tool marks.

d. Contamination.

e. Surface roughness or deformation.

NOTE:

If any of these conditions are observed, the part is defec-

tive and must be replaced.

7. The mating faces of the fitting should be joined squarely,

with no lateral or longitudinal strain on the fitting.

8. The nut should be torqued per the values on the outline

drawing (page 6).

9. When tightening the flare joints two wrenches must be

used. The fitting must be securely supported by the

stationary wrench.

10. Flared joints are not field repairable. If any damage is

found, that portion must be cut from the tubing and the

flare remade.

LEAK CHECK

IMPORTANT:

Replace pressure tap port valve core before attaching hoses for

evacuation.

After the installing of refrigerant lines to both the outdoor

and indoor unit is completed, the field connections must be

checked for leaks. Pressurize through the service valve ports,

the indoor unit and field refrigerant lines with dry nitrogen

to 350-400 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 refrigerant charge, the gas and

liquid line valves 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:

Unnecessary 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.

Evacuate until the micron gauge reads no higher than

350 microns.

Close off valve to vacuum pump and observe the micron

gauge. If gauge pressure rises above 500 microns in one (1)

minuS, then evacuation is incomple_ or sys_m has a leak.

If vacuum gauge does not rise above 500 microns in

one (1) minute, the evacuation should be complete.

With vacuum pump and micron gauge blanked 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 I/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

m_d backout coun_rclockwise until valve s_m just touches

rolled edge (approximately five [5] turns) observing

WARNING statement on page 2. See Figure 4.

10. Replace liquid service pressure tap port cap and valve

stem cap. These caps MUST BE REPLACED to

prevent leaks. Replace valve stem cap 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 gas valve by removing the shut-offvalve

cap and turning the valve stem 1/4 turn counterclock-

wise, using 1/4" Open End or Adjustable wrench. See

Figure 5. For brass gas line service valve opening,

follow 9 and 10 above. See Figure 4.

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

valve stein cap to prevent leaks. Again, these caps

MUST BE REPLACED to prevent leaks. Replace valve

stem cap and pressure tap cap finger tight, then tighten

an additional 1/6 turn. See Figure 5.

If refrigerant lines are longer than 15 feet and/or a

diffhrent size than recommended, it will be necessary to

adjust system refrigerant charge upon completion of

installation. See unit Service Facts.
