Storage - Trane RTWB Helical-Rotary Installation Operation & Maintenance

Storage

If the chiller is to be stored for at
least one month prior to the
installation, observe the following
precautions:
– Do not remove the protective
coverings from the unit.
– Store the chiller in a dry, vibration-
free secure area.
– At least every three months, check
the pressure in the refrigerant
circuit. If the condensing pressure
is below 4 bar at 20°C, call a
qualified service organization and
the appropriate Trane sales office.
Location requirements
Noise considerations
– Refer to the engineering bulletin
for noise-consideration
applications.
– Locate the unit away from sound-
sensitive areas.
– Install the isolation pads under the
unit.
– Install the rubber vibration
isolators in all water piping.
– Use flexible electrical conduit.
Note: Consult an acoustical engineer
for critical applications.
Foundation
Provide rigid, non-warping
mounting pads or a concrete
foundation of sufficient strength and
mass to support the chiller operating
weight (including completed piping
and full operating charges of
refrigerant, oil, and water). Refer to
Table 2 for unit operating weights.
When in place, level the chiller
within 6 mm over its length and
width. The Trane Company is not
responsible for equipment problems
resulting from an improperly-
designed or -constructed
foundation.

Installation Mechanical
Vibration eliminators
– Provide rubber boot-type isolators
for all water piping at the unit.
– Provide flexible conduit for
electrical connections to the unit.
– Isolate all pipe hangers and be
sure they are not supported by
main structure beams that could
introduce vibration into occupied
spaces
– Make sure that the piping does
not put additional stress on the
unit.
Note: Do not use metal-braided-
type eliminators on the water
piping. Metal braided eliminators
are not effective at the frequencies
at which the unit will operate.
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.
Figure 4: Minimum service clearance
1 Minimum clearance for maintenance.
2 Minimum clearance for tube removal of the evaporator or condenser (at
either end of the unit).
Dimensions in mm
Allow adequate clearance for
condenser and compressor
servicing. A minimum of 1 meter is
recommended for compressor
service and to provide sufficient
clearance for the opening of the
control panel doors. Refer to Figure
4 for minimum clearances required
for condenser-tube service. In all
cases, local codes will take
precedence over these
recommendations.
Note: Required vertical clearance
above the unit is 1 meter. There
should be no piping or conduit
located over the compressor motor.
If the room configuration requires a
variance to the clearance
dimensions, contact your Trane sales
office representative.
Note: Maximum clearances are
given depending on the unit
configuration; some units may
require less clearance than others in
the same category.
Local regulations may provide for
specific requirements.
