Installation — Mechanical
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, to provide sufficient clearance for
the opening of control panel doors and unit service. Refer to
Figure 8 , Figure
9 and Figure 12 for minimum clearances. In all cases, local codes which
require additional clearances will take precedence over these recommenda-
tions.
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.
Additional Location Requirements for Remote Evaporator Only
The Remote evaporator must be installed in a conditioned space, unless:
• The ambient temperature is always greater than 32 F.
• The system circulating liquid is a non-freezing glycol-type solution,
selected for the prevailing ambient temperature. The evaporator is
protected from freezing by properly installed and applied insulation and
heat tape.
CAUTION
Freezing Equipment Damage!
To prevent damage due to freezing, do not install the unit outside
without adequate freeze protection.
The remote evaporator should be mounted on a base of suitable strength to
support the operating weight. Remote evaporator weights and mounting
locations are shown in
Figure 10 and Figure 11 .
The remote evaporator must be level when installed. Be sure to allow
adequate clearance for water and refrigerant piping connection, performance
of service procedures, reading of gauges and thermometers, and operation
of valves. Space must be allowed at one end of the evaporator to pull tubes,
if required.
Rigging
The Model RTAA chiller should be moved by lifting. Refer to Figure 4 for
typical unit lifting and weights. Refer to the rigging diagram that ships with
each unit for specific “per unit” weight data.
WARNING
Heavy Objects!
Do not use cables (chains or slings) except as shown. Each of the
cables (chains or slings) used to lift the unit must be capable of
supporting the entire weight of the unit. Lifting cables (chains or
slings) may not be of the same length. Adjust as necessary for
even unit lift. Other lifting arrangements may cause equipment or
property-only damage. Failure to properly lift unit may result in
death or serious injury. See details below.
