Installation – Mechanical
Location Requirements
Sound Considerations
The most effective form of acoustical isolation is to
locate the unit away from any sound sensitive area.
Structurally transmitted sound can be reduced by
elastomeric vibration eliminators. Spring isolators are
not recommended. Consult an acoustical engineer in
critical sound applications.
Foundation
Figure 2 - Installation example
For maximum isolation effect, water lines and electrical
conduit should also be isolated. Wall sleeves and rubber
isolated piping hangers can be used to reduce the sound
transmitted through water piping. To reduce the sound
transmitted through electrical conduit, use exible
electrical conduit.
EU and Local codes on sound emissions should always
be considered. Since the environment in which a sound
source is located affects sound pressure, unit placement
must be carefully evaluated. Consult an acoustical
engineer for critical applications.
Provide rigid, non-warping mounting pads or a concrete
foundation of sufcient strength and mass to support
the applicable operating weight (i.e. including completed
piping, and full operating charges of refrigerant, oil and
water). Refer to the chapter on Unit Dimensions/Weights
for unit operating weights. Once in place, the unit must
be level with 3 mm over its length and width. Trane is
not responsible for equipment problems resulting from
an improperly designed or constructed foundation.
Clearances
Provide enough space around the unit to allow the
installation and maintenance personnel unrestricted
access to all service points. Refer to submittal drawings
for the unit dimensions, to provide sufcient 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.
Winter operation: CXAX coil will not be obstructed at
any time by snow or ice.
Specic attention should be paid to avoid accumulation
of ice and snow at the bottom of the coil.
Rigging
Refer to weights tables for typical unit lifting weights.
Refer to the rigging label attached to the unit for further
details.
Lifting Procedure
Refer to the lifting label afxed to the unit. Lifting beam
crossbars MUST be positioned so lifting cables do not
contact the sides of the unit. Adjust as necessary for
even level lift.
1- Use the four rigging points which are built into the
unit.
2- Slings and a spreader bar are to be provided by the
rigger.
3 - The minimum lifting capacity of each sling as well
as the spreader bar must be equal or higher than the
tabulated unit shipping weight.
4- Caution: this unit must be lifted and handled with
care. Avoid shocks while handling.
Unit isolation and Leveling
Mounting
Construct an isolated concrete pad for the unit or
provide concrete footings at each of the four unit
mounting points. Mount the unit directly to the concrete
pads or footings. Level the unit using the base rail as a
reference. The unit must be level within 5 mm over the
entire length. Use shims as necessary to level the unit.
Isolation Pads installation (Optional)
Install the optional neoprene pads at each mounting
location. Refer to unit submittals for further details
on location. Consult a vibration engineer for critical
applications.
Evaporator piping
Evaporator water connections are grooved. Thoroughly
ush all water piping to the CGAX or CXAX units
before making the nal 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 ushing 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 qualied
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.
