NOTE: If 'Export' packaging is needed, please contact
your local Carrier representative.
A m long rear suspension rail is supplied. This assembly
allows suspension of six size 1 4GM units. The rails can be
cut to the required length if necessary.
The front fastening supports are supplied pre-assembled in
a sub-assembly of five elements.
Foam plates are glued to each support face; their function
is to ensure the leak-tightness of the installed assembly
(collars, front support, 4GM).
They are generally supplied with the fresh air controllers
installed (without motorized valve).
NOTE: When the material is received, it is important to
verify that these joint plates are not damaged. Also, please
ensure that these joints are not damaged during installation
of the supports.
All screws required to assemble the collars on the front
support are supplied loosely screwed into the collars.
NOTE: Immediately check for damage in transit when
any shipment is received.
To protect against damage and contamination, leave all
packages fully wrapped until the units are about to be
installed.
For the same reasons leave the air inlets and outlets
covered with the protective film until the air ducts are
about to be connected.
2.5 - receiving a shipment - installation methods
When receiving a shipment, check the condition of the goods
and report any damage in transit to the shipping company.
Do not unpack the units until just before they are due to
be installed, and make sure they are as close as possible to
the installation site when unpacking them. Do not stack the
units and do not place heavy articles of any sort on them.

WARNING: When moving the 42GM units do not use
water pipes, condensate drain pipes, flexible pipes, fresh
air connections to lift them, nor the supply or return air
openings which are protected by an adhesive plastic film
(this film should be removed at the last moment when the
module is attached to its support). If these instructions
are not followed, serious damage could be caused (e.g. to
the electric heater).
Do not install a unit where flammable gases or products of
an acidic or alkaline character may be present. The copper/
aluminium coil or plastic components inside the unit could
suffer irreparable corrosion damage in their presence.
The presence of electrical components creates hazards to
those installing and servicing these units. Only properly
qualified electricians are authorized to install, service and
repair these units. Some routine maintenance such as filter
replacement may be entrusted to non-skilled personnel.
Before carrying out any work, all personnel must familiarize
themselves with the contents of this manual and all informa-
tive tags and labels attached to the units.
It is essential to adhere to all applicable safety regulations.
Wear eye protectors, work gloves and non-flammable
clothing when soldering or brazing. Always have a fire
extinguisher of the appropriate type close at hand.
WARNING: Disconnect the power supply to the unit and
to any accessories before carrying out any work on a unit.
WARNING: Failure to take proper account of the above
advice and unauthorised modification of the electrical
connections will render the Carrier warranty on the product
null and void.
