tion pack upon completion of work.

Condensing Units

These instructions do not cover all variations in systems or provide for every possible contingency to be met in connection with

the installation. 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.

Note: The manufacturer recommends installing only approved matched indoor and outdoor systems. All of the manufacture’s split

systems are A.H.R.I. rated only with TXV/EEV indoor systems. Some of the benefits of installing approved matched indoor and

outdoor split systems are maximum efficiency, optimum performance and the best overall system reliability.

WARNING

This information is intended for use by individuals

possessing adequate backgrounds of electrical and

mechanical experience. Any attempt to repair a central

air conditioning product may result in personal injury

and/or property damage. The manufacture or seller

cannot be responsible for the interpretation of this

information, nor can it assume any liability in connec-

tion with its use.

These units use R-410A refrigerant which operates

at 50 to 70% higher pressures than R-22. Use only

R-410A approved service equipment. Refrigerant cyl-

inders are painted a “Rose” color to indicate the type

of refrigerant and may contain a “dip” tube to allow

for charging of liquid refrigerant into the system. All

R-410A systems use a POE oil that readily absorbs

moisture from the atmosphere. To limit this “hygro-

scopic” action, the system should remain sealed

whenever possible. If a system has been open to the

atmosphere for more than 4 hours, the compressor oil

must be replaced. Never break a vacuum with air and

always change the driers when opening the system

for component replacement. For specific handling

concerns with R-410A and POE oil reference Retrofit

Bulletins SS-APG006-EN and APP-APG011-EN.

Extreme caution should be exercised when opening

the Liquid Line Service Valve. Turn counterclockwise

until the valve stem just touches the rolled edge. No

torque is required. Failure to follow this warning will

result in abrupt release of system charge and may

result in personal injury and /or property damage.

UNIT CONTAINS R-410A REFRIGERANT!

R-410A operating pressures exceed the limit of R-22.

Proper service equipment is required. Failure to use

proper service tools may result in equipment damage

or personal injury.

SERVICE

USE ONLY R-410A REFRIGERANT AND AP-

PROVED POE COMPRESSOR OIL.

WARNING

LIVE ELECTRICAL COMPONENTS!

During installation, testing, servicing, and trouble-

shooting of this product, it may be necessary to work

with live electrical components. Failure to follow all

electrical safety precautions when exposed to live

electrical components could result in death or serious

injury.

▲

WARNING

If using existing refrigerant lines make certain that all

joints are brazed, not soldered.

▲CAUTION

Scroll compressor dome temperatures may be hot. Do

not touch the top of compressor; it may cause minor to

severe burning.

1. The maximum length of refrigerant lines

from outdoor to indoor unit should NOT

2. The maximum vertical change should not

exceed twenty five (25) feet*.

shown in Table 5.1.

Note: For line lengths greater than sixty (60)

feet, Refer to Refrigerant Piping Application

Guide, SS-APG006-EN or Refrigerant Piping

Software Program, 32-3312-03 (or latest revi-

sion).

Restricted to maximum vertical change of 25 ft.

Table 2.1

When mounting the outdoor unit on a roof, be

sure the roof will support the unit’s weight.

Properly selected isolation is recommended to

alleviate sound or vibration transmission to the

building structure.

Please refer to application bulletin APP-

APG013-EN for detailed mounting information.

2.3 Suggested Locations for Best Reliability

Ensure the top discharge area is unrestricted for

at least five (5) feet above the unit.

Three (3) feet clearance must be provided in

front of the control box (access panels) and any

other side requiring service.

Do not locate close to bedrooms as operational

sounds may be objectionable.

Min. 12” to

Shrubbery Min. 12”

to Wall

Position the outdoor unit a minimum of 12” from

any wall or surrounding shrubbery to ensure

adequate airflow.

Outdoor unit location must be far enough away

from any structure to prevent excess roof runoff

water from falling directly on the unit.

2.4 Coastal Considerations

If installed within one mile of salt water, including seacoasts and inland waterways, models without factory

supplied Seacoast Salt Shields require the addition of BAYSEAC001 (Seacoast Kit) at installation time. Please

refer to Application Guide SS-APB006-EN: Trane - Sea Coast Applications and Seascoast Corrosion Protection

Bulletin UN-SVB11A-EN.

STEP 2 - To remove the unit from the pallet,

remove tabs by cutting with a sharp tool.

Section 3. Unit Preparation

3.1 Prepare The Unit For Installation

STEP 1 - Check for damage and report prompt-

ly to the carrier any damage found to the unit.

Section 4. Setting the Unit

4.1 Pad Installation

When installing the unit on a support pad, such

as a concrete slab, consider the following:

• The pad should be at least 1” larger than the

unit on all sides.

• The pad must be separate from any structure.

• The pad must be level.

• The pad should be high enough above grade

to allow for drainage.

• The pad location must comply with National,

State, and Local codes.

For other applications refer to Application Guide

APP-APG013-EN.

Trane outdoor condensing units are factory charged with the system charge required for the outdoor condensing

unit, ﬁfteen (15) feet of tested connecting line, and the smallest indoor evaporative coil match. If connecting line

length exceeds ﬁfteen (15) feet and/or a larger indoor evaporative coil is installed, then ﬁnal refrigerant

charge adjustment is necessary.

18-AC95D1-1 7

5.5 Reuse Existing Refrigerant Lines

For retrofit applications, where the existing

indoor evaporator coil and/or refrigerant lines

will be used, the following precautions should

be taken:

• Ensure that the indoor evaporator coil and

refrigerant lines are the correct size.

• Ensure that the refrigerant lines are free of

leaks, acid, and oil.

Important: For more information see publi-

cation numbers SS-APG006-EN and APP-

APG011-EN.

▲CAUTION

If using existing refrigerant lines make certain that

all joints are brazed, not soldered.

Section 6. Refrigerant Line Routing

6.1 Precautions

Important: Take precautions to prevent noise

within the building structure due to vibration

transmission from the refrigerant lines.

For Example:

• When the refrigerant lines have to be fastened to floor joists or other framing in a structure, use isolation type

hangers.

• Isolation hangers should also be used when refrigerant lines are run in stud spaces or enclosed ceilings.

• Where the refrigerant lines run through a wall or sill, they should be insulated and isolated.

• Isolate the lines from all ductwork.

• Minimize the number of 90º turns.

Comply with National, State, and Local Codes when

isolating line sets from joists, rafters, walls, or other

structural elements.

Section 7. Refrigerant Line Brazing

7.1 Braze The Refrigerant Lines

STEP 1 - Remove caps or plugs. Use a debur-

ing tool to debur the pipe ends. Clean both

internal and external surfaces of the tubing

using an emery cloth.

18-AC95D1-1 9

STEP 2 - Remove the pressure tap cap and

valve cores from both service valves.

STEP 3 - Purge the refrigerant lines and indoor

coil with dry nitrogen.

STEP 4 - Wrap a wet rag around the valve

body to avoid heat damage and continue the

dry nitrogen purge.

Braze the refrigerant lines to the service

valves.

Continue the dry nitrogen purge. Do not re-

move the wet rag until all brazing is completed.

Important: Remove the wet rag before stopping

the dry nitrogen purge.

NOTE: Precautions should be taken to avoid

heat damage to basepan during brazing. It is

recommended to keep the flame directly off of

the basepane.

10 18-AC95D1-1

STEP 5 - Replace the pressure tap valve cores

after the service valves have cooled.

STEP 2 - Check for leaks by using a soapy solu-

tion or bubbles at each brazed location.

Remove nitrogren pressure and repair any leaks

before continuing.

Section 8. Refrigerant Line Leak Check

8.1 Check For Leaks

STEP 1 - Pressurize the refrigerant lines and

evaporator coil to 150 PSIG using dry nitrogen.
