Introduction

Unit Description

The RTSF units are helical-rotary type, water-cooled,
liquid chillers, designed for installation indoors.
The RTSF units are packaged with an evaporator
and condenser.

Note: Each RTSF 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 RTSF series features Trane’s exclusive Adaptive
Control logic with UC800 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 efficiencies, avoid
chiller shutdown, and keep producing chilled water.

Compressor loading/unloading is provided by AFD
(Adaptive Frequency Drive) coordinated with slide
valve operation.

Each refrigerant circuit is provided with filter, sight glass,
electronic expansion valve, and charging valves on
the RTSF.

The evaporator and condenser are manufactured
in accordance with Pressure Equipment Directive
standards. The evaporator and the condenser are
insulated according the option ordered. Both evaporator
and condenser water pipes are equipped with water
drain and vent connections.

Maintenance contract

It is strongly recommended that you sign a maintenance
contract with your local Trane 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.

Refrigerant

Consult the addendum to Manuals for units with
refrigerant, for conformity to the Pressure Equipment
Directive (PED) 97/23/EC or 2014/68/EU and Machinery
Directive 2006/42/EC and for specific caution for R1234ze.

Installation overview and
requirements

Contractor responsibilities

A list of the contractor responsibilites typically associated
with the installation process is provided in Table 2.

• Locate and maintain the loose parts. Loose parts are
located in the control panel.

• Install the unit on a foundation with flat support surfaces,
level within 5 mm and of sufficient strength to support
concentrated loading. Place the manufacturer-supplied
isolation pad assemblies under the unit.

• Install the unit per the instructions outlined in the
“Mechanical Installation” section.

• Complete all water piping and electrical connections.

Note: Field piping must be arranged and supported to
avoid stress on the equipment. It is strongly recommended
that the piping contractor provide at least 1m of clearance
between the pre-installation piping and the planned location
of the unit. This will allow for proper fit-up upon arrival
of the unit at the installation site. All necessary piping
adjustments can be made at that time

• Where specified, supply and install valves in the water

piping upstream and downstream of the evaporator and
condenser, to isolate the heat exchangers for maintenance
and to balance/trim the system.

• Supply and install flow switches or equivalent devices
in both the chilled water and condenser water piping.
Interlock each switch with the proper pump starter and
Tracer UC800, to ensure that the unit can only operate
when water flow is established.

• Supply and install taps for thermometers and pressure
gauges in the water piping, adjacent to the inlet and outlet
connections of both the evaporator and the condenser.

• Where specified, supply and install strainers ahead of all

pumps and automatic modulating valves.

• Supply and install refrigerant pressure relief piping from
the pressure relief to the atmosphere.

• Start the unit under supervision of a qualified service
technician.

• Where specified, supply and insulate the evaporator

and any other portion of the unit, as required, to prevent
sweating under normal operating conditions.

• For unit-mounted starters, cutouts are provided at the top
of the panel for line-side wiring.

• Supply and install the wire terminal lugs to the starter.

• Supply and install field wiring to the line-side lugs of the
starter.

Installation - Mechanical

Storage

If the chiller is to be stored more than one month prior to
installation, observe the following precautions:

• Do not remove the protective coverings from the
electrical panel.

• Store the chiller in a dry, vibration-free, secure area.

• At least every three months, attach a gauge and

manually check the pressure in the refrigerant circuit.
If the refrigerant pressure is below 3.4 bar at 21°C (2 bar
at 10 °C), call a qualified service organization and the
appropriate Trane sales office.

NOTE: Pressure will be approximately 1.0 bar if shipped
with the optional nitrogen charge.

Noise Considerations

• Refer to Engineering Bulletin for sound consideration

applications.

• Locate the unit away from sound-sensitive areas.

• Install the isolation pads under the unit. Refer to “Unit

Isolation.”

• Install rubber vibration isolators in all water piping.

• Use flexible electrical conduit for final connection to the

Tracer UC800.

• Seal all wall penetrations.

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 General information for unit operating weights.

Once in place, level the chiller within 5 mm over its
length and width.

The manufacturer 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. A minimum of 1 m is
recommended for compressor service and to provide
sufficient clearance for the opening of control panel
doors. In all cases, local codes will take precedence
over these recommendations. If the room configuration
requires a variance to the clearance dimensions, contact
your sales representative.

NOTE: Required vertical clearance above the unit is at
least 1 m. There should be no piping or conduit located
over the compressor motor.

NOTE: Maximum clearances are given. Depending on
the unit configuration, some units may require less
clearance than others in the same category.

Ventilation

The unit produces heat even though the compressor is
cooled by the refrigerant. Make provisions to remove
heat generated by unit operation from the equipment
room. Ventilation must be adequate to maintain an
ambient temperature lower than 40°C. Vent the pressure
relief valves in accordance with all local and national
codes. Refer to “Pressure Relief Valves”. Make provisions
in the equipment room to keep the chiller from being
exposed to ambient temperatures below 10°C.

Water Drainage

Locate the unit near a large capacity drain for water
vessel drain-down during shutdown or repair. Condenser
and evaporator water pipes are provided with drain
connections. Refer to “Water Piping.” All local and
national codes apply.

Access Restrictions

Refer to the unit submittals for specific dimensional
information (documents supplied in document package
coming with unit).

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.

foundations. This depends on the building structure.
It is recommended for these situations to use neoprene
isolators instead of elastomeric pads.
Drawings to locate isolation pads are supplied with
unit document package.

2. During final positioning of the unit, place the isolation

pads as indicated in submittal drawings. Level
the unit.

Unit Leveling

NOTE: The electrical panel side of the unit is designated

as the “front” of the unit.

1. Check unit level end-to-end by placing a level on the
chiller structure (compressor frame for example).

2. Adjust to within 5 mm of level front-to-back.

Water Piping

Piping Connections

To prevent equipment damage, bypass the unit if using
an acidic flushing agent.

Make water piping connections to the evaporator
and condenser. Isolate and support piping to prevent
stress on the unit. Construct piping according to local
and national codes. Insulate and flush piping before
connecting to unit.

The chilled water connections to the evaporator are to be
grooved-pipe type connections. Do not attempt to weld
these connections. Refer to submittal for dimension of
tube stub for grooved connection. Refer to submittal for
dimension of tube stub for grooved connection.

To prevent damage to chilled water components, do not
allow evaporator pressure (maximum working pressure)
to exceed 10 bar.

Reversing Water Connections is prohibited

It is critical to keep the factory layout for water
connections. Therefore reversing water connections may
lead to functional disorder.

NOTE: Dimensions of tube stub for grooved connection
are included in submittal drawings.

Vents and Drains

Install pipe plugs in evaporator and condenser water
connections drain and vent connections before filling
the water systems. To drain water, remove vent and drain
plugs, install a NPT connector in the drain connection
and connect a hose to it.

Water Treatment

WARNING: Do not use untreated or improperly treated
water. Use of untreated or improperly treated water may
result in equipment damage.

The following disclamatory label is provided on
each unit:

The use of improperly treated or untreated water in this
equipment may result in scaling, erosion, corrosion,
algae or slime. The services of a qualified water
treatment specialist should be engaged to determine
what treatment, if any, is advisable. The warranty
specifically excludes liability for corrosion, erosion
or deterioration of the manufacturer’s equipment.
The manufacturer assumes no responsibilities for the
results of the use of untreated or improperly treated
water, or saline or brackish water.

Evaporator Piping Components

Note: Make sure all piping components are between the
shutoff valves, so that isolation can be accomplished
on both the condenser and the evaporator. “Piping
components” include all devices and controls used
to provide proper water system operation and unit
operating safety. These components and their general
locations are given below.

Entering Chilled Water Piping

• Air vents (to bleed air from system)

• Water pressure gauges with shutoff valves

• Pipe unions

• Vibration eliminators (rubber boots)

• Shutoff (isolation) valves

• Thermometers

• Clean out tees

• Pipe strainer

Leaving Chilled Water Piping

• Air vents (to bleed air from system)

• Water pressure gauges with shutoff valves

• Pipe unions

• Vibration eliminators (rubber boots)

• Shutoff (isolation) valves

• Thermometers

• Clean out tees

• Balancing valve

• Pressure relief valve

To prevent evaporator damage, do not exceed 10 bar
evaporator water pressure for standard units.

To prevent heat exchangers damage, install a strainer
in the evaporator water inlet piping.

Condenser Piping Components

“Piping components” include all devices and controls
used to provide proper water system operation and unit
operating safety. These components and their general
locations are given below.

Entering Condenser Water Piping

• Air vents (to bleed air from system)

• Water pressure gauges with shutoff valves

• Pipe unions

• Vibration eliminators (rubber boots)

• Shutoff (isolation) valves

• Thermometers

• Clean out tees

• Pipe strainer

• Flow switch

Water Pressure Gauges and
Thermometers

Install field-supplied thermometers and pressure gauges
(with manifolds, whenever practical). Locate pressure
gauges or taps in a straight run of pipe; avoid placement
near elbows, etc. Be sure to install the gauges at the
same elevation on each shell if the shells have opposite­end water connections.

Installation - Mechanical

Water Pressure Relief Valves

Install a pressure relief valve in both evaporator and
condenser water systems. Failure to do so could result
in Heat Exchanger damage.

When shutoff valves are installed on the water circuits,
the water temperature can increase and create a high
pressure in the water systems. Refer to applicable
regulation for relief valve installation guidelines.

Flow Sensing Devices

Use field-provided flow switches or differential pressure
switches with pump interlocks to sense system water
flow.

To provide chiller protection, install and wire flow
switches in series with the water pump interlocks, for
both chilled water and condenser water circuits (refer to
the “Installation Electrical” section). Specific connections
and schematic wiring diagrams are shipped with the
unit.

Flow switches must stop or prevent compressor
operation if either system water flow drops off
drastically. Follow the manufacturer’s recommendations
for selection and installation procedures. General
guidelines for flow switch installation are outlined below.

• Mount the switch upright, with a minimum of 5 pipe

diameters of straight, horizontal run on each side.

• Do not install close to elbows, orifices or valves.

Note: The arrow on the switch must point in the direction
of the water flow. To prevent switch fluttering, remove all
air from the water system.

Note: The Tracer UC800 provides a 6-second time delay
on the flow switch input before shutting down the unit
on a loss-of-flow diagnostic. Contact a qualified service
organization if nuisance machine shutdowns persist.
Adjust the switch to open when water flow falls below
nominal. Refer to the General Data table for minimum
flow recommendations. Flow switch contacts are closed
on proof of water flow.

Refrigerant Pressure Relief Valve
Venting

To prevent injury due to inhalation of refrigerant gas, do
not discharge refrigerant anywhere. If multiple chillers
are installed, each unit must have separate venting for
its relief valves. Consult local regulations for any special
relief line requirements.

All relief valve venting is the responsibility of the
installing contractor. All RTSF units use condenser
pressure relief valves that must be collected. Relief valve
connection sizes and locations are shown in the unit
submittals. Refer to national regulations for relief valve
vent line sizing information.

Do not exceed vent piping code specifications. Failure
to heed specifications could result in capacity reduction,
unit damage and/or relief valve damage.

Note: Once opened, relief valves tend to leak.
