Ductable ceiling-suspended unit
SS-SVX07B-E4
About the unit
MCD/MWD units are assembled,
pressure tested, dehydrated, charged
and run tested before shipment.
MCD units are designed to operate
in cooling mode only, whereas MWD
can operate in cooling or heating
modes. This unit with its mounted
accessories is in conformity with the
provisions of the low voltage
directive 73/23/EEC and
electromagnetic compatibility
directive 89/336/EEC as amended,
and in conformity with nation
implementing legislation.
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 electronic leak detector to
determine the hermetic integrity of
the unit. The refrigerant charge is not
included in the standard Warranty
Cover.
Refrigerant
The refrigerant provided by the
constructor 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. Do not release refrigerant
into the atmosphere.
Foreword
These Installation Operation and
Maintenance instructions are given
as a guide to good practice in the
installation, start-up, operation and
periodic maintenance by the user of
MCD/MWD. 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.
Warranty
Warranty is based on the general
terms and conditions of the
constructor. 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 maintenance, 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 of chapter "Maintenance", it
may entail cancellation of warranty
and liabilities by the constructor.
About this manual
The information contained in this
manual applies to units designated
MCD/MWD. 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 constructor assumes
no liability for installations or
servicing performed by unqualified
personnel. Read this manual
carefully and the manual on the
installation of the outdoor unit
before starting to install the system.

Before starting
Creation of refrigerant lines
To create the refrigerant lines you
will need refrigeration quality
annealed copper tubing. These tubes
are available on the local market
together with the insulation and
mounting equipment. These units
must be connected using screw
connections/flare type for unit sizes
512 to 536 and brazed connections
for unit sizes 048-060.
Electrical connections
Use insulated copper wire. The
section of the core varies depending
on the length required. Refer to
table 1 for the recommended
sections. The wiring and electrical
connections must comply with
national electricity regulations.
Check that the electrical
characteristics on the nameplate
correspond to those of the national
grid. The electrical installation shall
include a disconnect switch in
compliance with local electrical
regulations.
WARNING!
Never open the indoor or outdoor
unit without first disconnecting the
power supply. There is a risk of
electrocution.
