Foreword
These instructions are given as a
guide to good practice in the
installation, start-up, operation, and
maintenance by the user, ofTrane
RTAD chillers.They do not contain
full service procedures necessary for
the continued successful operation of
this equipment.The services of a
qualified technician should be
employed through the medium of a
maintenance contract with a
reputable service company. Read
this manual thoroughly before unit
start-up.
Units are assembled, pressure
tested, dehydrated, charged and run
tested before shipment.
Warnings and cautions
Warnings and Cautions appear at
appropriate sections throughout this
manual.Your personal safety and the
proper operation of this machine
require that you follow them
carefully.The constructor assumes
no liability for installations or
servicing performed by unqualified
personnel.
WARNING! Indicates a potentially
hazardous situation which, if not
avoided, could result in death or
serious injury.
CAUTION! Indicates a potentially
hazardous situation which, if not
avoided, may result in minor or
moderate injury. It may also be used
to alert against unsafe practices or
for equipment or property-damage-
only accidents.
Safety recommendations
To avoid death, injury, equipment or
property damage, the following
recommendations should be
observed during maintenance and
service visits:
1.The maximum allowable pressures
for system leak testing on low and
high pressure side are given in the
chapter "Installation". Always
provide a pressure regulator.
2. Disconnect the main power supply
before any servicing on the unit.
3. Service work on the refrigeration
system and the electrical system
should be carried out only by
qualified and experienced
personnel.
Reception
On arrival, inspect the unit before
signing the delivery note.
Reception in France only:
In case of visible damage:The
consignee (or the site representative)
must specify any damage on the
delivery note, legibly sign and date
the delivery note, and the truck
driver must countersign it. The
consignee (or the site representative)
must notifyTrane Epinal Operations -
Claims team and send a copy of the
delivery note.The customer (or the
site representative) should send a
registered letter to the last carrier
within 3 days of delivery.
Note: for deliveries in France, even
concealed damage must be looked
for at delivery and immediately
treated as visible damage.
General information

RTAD-SVX01F-E4 3
General information
Reception in all countries except
France:
In case of concealed damage:The
consignee (or the site representative)
must send a registered letter to the
last carrier within 7 days of delivery,
claiming for the described damage. A
copy of this letter must be sent to
Trane Epinal Operations - Claims
team.
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.
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.
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.

Note:
All Free Cooling units must be freeze protected with 30% Ethylene Glycol in the cooling loop circuit which is the most convenient percentage in order
to protect the unit against freezing.
Protection coverage with 30% Ethylene Glycol:
- freezing point without burst effect = -13°C;
- freezing point with burst effect = -50°C.
