Installation - Mechanical
Packaged Unit and Units with
Remote Evaporator Option

General

The following instructions are, for the
most part, applicable to both packaged
units and units with the remote
evaporator option. Specific exceptions
are noted.
The most significant difference in the
installation of the two systems is the
requirement for interconnecting piping
with the remote evaporator option. For
this reason, these installation
procedures are covered separately in
the following section, Installation -
Mechanical, Remote Evaporator
Interconnecting Piping.

Pre-installation

Report any damage incurred during
handling or installation to the Trane
sales office immediately. An Installation
Check Sheet is provided.

Location Requirements

Noise Considerations

Locate the outdoor unit away from
sound sensitive areas. If required,
install rubber vibration isolators in all
water piping and use flexible electrical
conduit. Refer to "Unit Isolation".
Consult an acoustical engineer for
critical applications. Also refer to Trane
Engineering Bulletins for application
information on RTAA chillers.

Foundation

Provide rigid, non-warping mounting
pads or a concrete foundation of
sufficient strength and mass to support
the outdoor unit operating weight (i.e.,
including completed piping, and full
operating charges of refrigerant, oil and
water). Refer to Figures 18 thru 21 for
unit operating weights. Once in place,
the outdoor unit must be level within 1/
4" (6.4 mm) over its length and width.
The Trane Company is not responsible
for equipment problems resulting from
an improperly designed or constructed
foundation.

Clearances

Provide enough space around the
outdoor unit to allow the installation
and maintenance personnel
unrestricted access to all service points.
Refer to submittal drawings for the unit
dimensions. A minimum of four feet is
recommended for compressor service.
Provide sufficient clearance for the
opening of control panel doors. Refer
to Figures 9 thru 12 for minimum
clearances. In all cases, local codes
which require additional clearances will
take precedence over these
recommendations.
Note: If the outdoor unit configuration
requires a variance to the clearance
dimensions, contact your Trane Sales
Office Representative. Also refer to
Trane Engineering Bulletins for
application information on RTAA
chillers.
