General Information
MCW - SVN13A - E4
Foreword
These Installation instructions are
given as a guide to good practice in
the installation, start-up and operation
by the installers of MCW/MWW and
TTK/TWK mini-split systems.
They do not contain the full service
procedures necessary for the
continued successful operation of this
equipment. The services of a qualified
service technician should be
employed, through the medium of a
maintenance contract with a
reputable service company.
Read them completely before doing
anything with your air conditioning
system.
Warranty
Warranty is based on the general
terms and conditions of the con-
structor. The warranty is void if the
equipment is modified or repaired
without the written approval of the
constructor, if the operating limits are
exceeded, or if the control system or
the electrical wiring is modified.
Damage due to misuse, lack of main-
tenance, or failure to comply with the
manufacturer’s instructions, is not
covered by the warranty obligation.
If the user does not conform to the
rules described in the manual, it may
entail cancellation of warranty and
liabilities by the Trane company.
Reception
On arrival, inspect the unit before
signing the delivery note. Specify any
damage on the delivery note, and
send a registered letter of protest to
the last carrier of the goods within 72
hours of delivery. Notify the local sales
office at the same time. The unit
should be totally inspected within 7
days of delivery. If any concealed
damage is discovered, send a
registered letter of protest to the
carrier within 7 days of delivery and
notify the local sales office. Units are
shipped with the refrigerant operating
or holding charge and should be
examined with an eletronic leak
detector to determine the hermetic
integrity of the unit. The refrigerant
charge is not included in the standard
Warranty Cover.
About this manual
Cautions appear at appropriate places
in this instruction manual Your
personal safety and the proper
operation of this machine require that
you follow them carefully. The con-
structor assumes no liability for
installations or servicing performed by
unqualified personnel.
All phases of the installation of these
air conditioning systems must
conformto all provinced/state and
local codes.
Please keep this installation manual
carefully for consultation.
About the unit
These MCW/MWW and TTK/TWK
units are assembled, pressure
tested, dehydrated, charged and run
tested before shipment. The
infomation contained in this manual
applies to units designated MCW/
MWW and TTK/TWK. MCW and TTK
units are designed to operate in
cooling mode only, whereas MWW
and TWK can operate in cooling or
heating modes.
Refrigerant
The refrigerant provided by the con-
structor 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
constructor warranty could be
cancelled.
Important
These instructions do not cover all
variations in system, nor do they
provide for every possible contin-
gency to be met.
Should further information be desired
or should particular problems arise
which are not covered sufficiently for
the purchaser’s purposes, the matter
should be referred to the Trane sales
office in your region.
