Foreword
These instructions are given as a
guide to good practice in the
installation, start-up, operation, and
maintenance by the user, of Trane
UniTrane™ CD/ ED fan coil units.
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.
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 notify
Trane 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 rance, even
concealed damage must be looked
for at delivery and immediately
treated as visible damage.
Reception in all countries except

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. inally,
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.
