General information
Warranty
Warranty is based on the general
terms and conditions of the
manufacturer. The warranty is
void if the equipment is repaired
or modified without the written
approval of the manufacturer, if the
operating limits are exceeded or if
the control system or the electrical
wiring is modified. Damage due
to misuse, lack of maintenance
or failure to comply with the
manufacturer’s instructions or
recommendations is not covered by
the warranty obligation. If the user
does not conform to the rules of this
manual, it may entail cancellation
of warranty and liabilities by the
manufacturer.
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.

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
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 flexible 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
sufficient 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 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.
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 affixed 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.

11CG-SVX06F-GB
Evaporator piping
Evaporator water connections are
grooved. Thoroughly flush all water
piping to the CGWN or CCUN
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.
Drainage
Locate the unit near a large capacity
drain for water vessel draindown
during shutdown or repair. Water
piping is provided with drain
connections. Refer to “Water
Piping.” All local and national codes
apply.
Piping
A vent is provided on the top of
the evaporator at the return end.
Be sure to provide additional vents
at high points in the piping to bleed
air from the chilled water system.
Install necessary pressure gauges
to monitor the entering and leaving
chilled water pressures.

8 = Strainer: avoid to get heat exchangers dirty. All installation must be equipped
with efficient strainer in order that only clean water enters into exchanger.
If there is no strainer, reserve will be formulated by the Trane technician at the start-
up of the unit. The strainer used must be able to stop all particles with a diameter
greater than 1 mm.
9 = Draining: used as the draining the plate heat exchanger.
10 = Do not start the unit with low water volume or not enough pressurized circuit.
Note: A pressure switch device to detect lack of water is not included in the
pump package. Installation of this type of device is highly recommended to
avoid sealing damage due to operation of pump without enough water.

Minimal installation water
content
The water volume is an important
parameter because it allows a
stable chilled water temperature and
avoids short cycle operation of the
compressors.
Parameters which influence
the water temperature
stability
• Water loop volume
• Load fluctuation
• Number of capacity steps
• Compressors rotation
• Dead band (adjusted on chiller
controller)
• Minimum time between 2 starts of
a compressor
Minimum water volume for
a comfort application
For comfort application we can
allow water temperature fluctuation
at part load. The parameter to
take into account is the minimum
operating time of the compressor.
In order to avoid lubrication problem
on a scroll compressor it must run
at least 2 minutes (120 seconds)
before it stops.
The following table gives the
minimal installation water content
recommended according to all these
parameters.

Installation
Insulation
Insulate refrigerant lines from
building itself to avoid transmission
to building structure of vibrations
normally caused by pipework. Also
avoid bypassing the unit’s damping
system by fixing the refrigerant
lines or the electrical ducts very
rigidly. Vibrations may propagate
into building structure through rigidly
fixed refrigerant lines.
Pressure tests and leak detection
WARNING! During operations, take
the following precaution:
1. Neither oxygen nor acethylene
should be used instead of
refrigerant and nitrogen to
detect leaks, otherwise a violent
explosion may occur.
2. Always use valves and
manometers to check the test
pressure in system. Excessive
pressure may either cause pipes
to rupture, damage unit, or cause
an explosion, causing possible
physical injury. Carry out liquid
line and hot gas pressure tests
in accordance with current
standards.
CAUTION: Do not go more than
0.7 bar above the high pressure
switch setpoint. Introduce enough
refrigerant into circuit for 85 to
100 kPa pressure, pump-injecting
dry nitrogen, and raise pressure
to 100 kPa. Search possible leaks
using detector. This operation
should be carried out great care
throughout the system. If leaks are
detected, reduce system pressure,
and repair defective component.
Repeat test process, to check that
the repair can withstand rated
pressure.
Refrigerant charge
CCUN units are delivered with a
nitrogen holding charge and isolating
valves. After system pressure and
vacuum testing, fill up unit with
refrigerant according to the diameter
and the length of the refrigerant
piping work up to obtain the correct
subcooling temperature:
t subcooling = 5°C for a liquid
temperature of 40°C.
Warning: When connecting CCUN
liquid and discharge lines , ensure
that the copper end pipes between
the stop valve and the end end of
the piping are not under pressure
using a 1/4 SAE.
Oil charge - CCUN
Above 60 kg of refrigerant charge
per circuit, special care to the oil
level on compressor is required.
The operating oil level shall remain
above half of the oil sight glass. See
the unit nameplate for oil charges.
The oil level can only be evaluated
after 10 minutes OFF time of both
compressors of the circuit. See
sticker for the oil level located on
the compressor next to the oil sight
glass. See Compressor oil level at oil
equalization line figures at the end
of “General startup” chapter.
Note: The oil quantity necessary
for the split system has also to be
adjusted according to the diameter
and the length of the refrigerant

recommended by TRANE
Important note:
These operations have to be
performed by a specialist. The
results have to be written on a start
up record by the Trane engineer
or the client’s specialist who has
performed this start up. The quantity
of refrigerant and oil added are at
the client’s charges.

Installation
High pressure
The remote condenser must have a
service pressure equal to or higher
than the high service pressure.
Note: CCUN is only one component
of a complete installation. It includes
its own high pressure protection set
at 44.5 bar for R410A units.

Pressure relief valve - CCUN
Above the maximum system
refrigerant charge, it is recommended
to install a pressure relief valve.
See figures below for installation.
Depending upon the liquid
line diameter selected in the
“Recommended liquid line diameters”
table, find the predicted maximum
liquid line length of installation
without pressure relief valve installed.
The recommended pressure relief
valve setting is 29 bar and shall be
installed on the low pressure side of
the refrigerant circuit.
The party in charge of the supply of
the condenser and of its refrigerant
piping is responsible of implementing
all the required protections to
comply with the PED requirements
for the design pressure of the
condenser installed.
Please refer to the document PROD-
SVX01_-xx delivered with this
chiller to check all the mandatory
conformity requirements of the
Pressure Equipment and Machinery
directives for this installation.

Installation
Winter freeze protection
During negative ambient air
temperature chilled water piping
must be fully insulated. Ensure that
all safeties are taken to prevent frost
damage during negative ambient air
temperature. The following systems
can be used:
1. Electrical heater mounted on all
water piping exposed to negative
temperatures.
2. Start chilled water pump during
negative ambient air temperature.
3. Add ethylene glycol in the chilled
water.
4. Drain water-circuit, however be
aware of corrosion process when
drained.
Note
If machinery room can be exposed to
temperature below 0°C, systems 2,
3 and 4 must be used.
CAUTION:
- There is a risk of freeze-up of
the evaporator circuit due to
internal refrigerant migration if the
condenser circuit is maintained at a
low temperature (below 0°C) for a
long period during the cold season.
If necessary, provide isolation valves
on the condenser water circuit
(CGWN). CCUN is protected against
refrigeration migration by a liquid
solenoid valve.
- When using the freeze protection
by pump activation during the cold
season, water must be able to
circulate freely.
Check that no closure valve on
other device might block waterflow.
Loading concentrated glycol in the
water loop at the suction side of the
pump is prohibited. It can severely
damage the mechanical seal of the
pump and consequently generate
potential water leaks.
