Installation

Notify your Trane representative of the damage and arrange for repair. Have the carrier 
inspect the damage before making any repairs to the unit.

Unit Storage

Take precautions to prevent condensate from forming inside the unit's electrical compartments 
and motors if the unit is stored before it is installed.

Service Access

Maintain adequate clearances around and above the unit to ensure proper unit operation and allow 
sufficient service access. Trane recommends 36-inches service access on all sides of the unit.

WARNING

Hazardous Voltage!

Disconnect all electric power, including remote disconnects before servicing. Follow proper 
lockout/tagout procedures to ensure the power can not be inadvertently energized. Failure to 
disconnect power before servicing could result in death or serious injury.

Acoustic Considerations

Before determining the final unit installation site, remember that proper unit placement is critical 
in reducing transmitting sound levels to the building. The ideal time to make provisions to reduce 
sound transmissions is during the design phase. The most economical means of avoiding a 
potential acoustical problem is to place units in areas that are not acoustically sensitive.

Unit Location

Install the unit in a dry, indoor area between 50 and 115°F. Choose a location where sound levels, 
airflow and vibration, commonly associated with heavy-duty commercial equipment, will not be 
objectionable to occupants. In multiple unit installations, separate the individual units and stagger 
their location from floor to floor so as not to starve units for air and not to discharge warm 
condenser air from one condenser into the intake of another condenser. Place thermostats, air 
supplies and returns so that the individual unit will operate within its zone.

Installation Preparation

Before installing the unit, perform the following procedures to ensure proper unit operation.

1.

Verify the installation location is level. To ensure proper unit operation, install the unit level 
(zero tolerance) in both horizontal axes. Failure to level the unit properly can result in 
condensate management problems, such as standing water inside the unit. Standing water and 
wet surfaces inside units can result in microbial growth (mold) in the drain pan that may cause 
unpleasant odors and serious health-related indoor air quality problem.

2. Allow adequate service and code clearances as recommended in the 

“Service Access,” p. 10

 

section.

3. Position the unit in its final location.

Unit Placement

Install the unit on a firm, level surface.

Installing Optional Accessories

Before installing ductwork, install accessories on unit.
