Refrigerant

The refrigerant provided by the manufacturer meets
all the requirements of our units. When using recycled
or reprocessed refrigerant, it is advisable to ensure its
quality is equivalent to that of a new refrigerant. For
this, it is necessary to have a precise analysis made by a
specialized laboratory. If this condition is not respected,
the manufacturer warranty could be cancelled.
Consult the addendum to Manuals for units with
refrigerant, for conformity to the Pressure Equipment
Directive (PED) 97/23/EC and Machinery Directive
2006/42/EC and for specifi c caution with R1234ze.

Maintenance contract

It is strongly recommended that you sign a maintenance
contract with your local Service Agency. This contract
provides regular maintenance of your installation by
a specialist in our equipment. Regular maintenance
ensures that any malfunction is detected and corrected
in good time and minimizes the possibility that serious
damage will occur. Finally, regular maintenance
ensures the maximum operating life of your equipment.
We would remind you that failure to respect these
installation and maintenance instructions may result in
immediate cancellation of the warranty.

Training

To assist you in obtaining the best use of it and
maintaining it in perfect operating condition over a long
period of time, the manufacturer has at your disposal
a refrigeration and air conditioning service school. The
principal aim of this is to give operators and technicians
a better knowledge of the equipment they are using,
or that is under their charge. Emphasis is particularly
given to the importance of periodic checks on the
unit operating parameters as well as on preventive
maintenance, which reduces the cost of owning the unit
by avoiding serious and costly breakdown.

Unit Description

The RTWD units are helical-rotary type, water-cooled,
liquid chillers, designed for installation indoors. The
units have 2 independent refrigerant circuits, with one
compressor per circuit. The RTWD units are packaged
with an evaporator and condenser.
Note: Each RTWD unit is a completely assembled,
hermetic package that is factory-piped, wired, leak-
tested, dehydrated, charged and tested for proper
control operations prior to shipment. The chilled water
inlet and outlet openings are covered for shipment.
The RTWD series features Trane's exclusive Adaptive
Control logic with CH530 controls. It monitors the
control variables that govern the operation of the chiller
unit. Adaptive Control logic can correct these variables,
when necessary, to optimize operational effi ciencies,
avoid chiller shutdown, and keep producing chilled
water. Compressor loading/unloading is provided by:
- Slide valve solenoid activated on RTWD SE, HE and XE
versions
- AFD (Adaptive Frequency drive) coordinated with slide
valve operation on RTWD HSE
Each refrigerant circuit is provided with fi lter, sight glass,
electronic expansion valve, and charging valves on
the RTWD.
The evaporator and condenser are manufactured
in accordance with Pressure Equipment Directive
standards. The evaporator is insulated according the
option ordered. Both evaporator and condenser are
equipped with water drain and vent connections.
The RTUD units are helical-rotary type compressor
chillers. The RTUD unit consists of an evaporator,
two helical rotary compressors (one per circuit), oil
separators, oil coolers, liquid line service valves, sight
glasses, electronic expansion valves and fi lter. The
discharge line leaving the oil separator and liquid line
entering the fi lters are capped and brazed. The unit ships
with a nitrogen holding charge but without oil charge.
