Location Requirements
Sound Considerations
The most effective form of acoustical isolation is to
locate the unit away from any sound sensitive area.

for the unit dimensions, to provide sufficient clearance
for the opening of control panel doors and unit service.
Refer to the chapter on Unit Dimensions/Weights for
minimum clearances. In all cases, local codes which
require additional clearances will take precedence over
these recommendations.
If the installation includes several units or if units are
close to walls, contact your local Trane Sales Office for
additional requirements.

Technical Data
Winter operation : CXAX coil will not be obstructed at
any time by snow or ice.
Specifc attention should be paid to avoid accumulation
of ice and snow at the bottom of the coil.

on location. Consult a vibration engineer for critical
applications.
Evaporator piping
Evaporator water connections are grooved. Thoroughly
flush all water piping to the CGAX or CXAX units
before making the final piping connections to the unit.
Components and layout will vary slightly, depending on
the location of connections and the water source.
CAUTION Equipment Damage!
If using an acidic commercial flushing solution, construct
a temporary bypass around the unit to prevent damage
to internal components of the evaporator.
CAUTION Proper Water Treatment!
The use of untreated or improperly treated water in a
chiller may result in scaling, erosion, corrosion, algae or
slime. It is recommended that the services of a qualified
water treatment specialist be engaged to determine
what water treatment, if any, is required. Trane assumes
no responsibility for equipment failures which result
from untreated or improperly treated water, or saline or
brackish water.
