Installation Instructions

Inspection
Upon reception, inspect the goods and notify
the carrier and the insurance company, in
writing, of any possible damage.

Environmental protection

Packing
Packing is made of recyclable
material. Its elimination should be
carried out in accordance with local
regulations on selective collection of residual
material.
Refrigerant
During installation and maintenance, keep in
mind that HFC-410A with POE oil is used.
Contains greenhouse effect fluorine gas
covered by the Kyoto Protocol.
For the type of gas and amount per system,
please see the identification plaque.
GWP (Global Warming Potential): 2088.
Elimination of the unit
Upon disassembly of the unit, the compo-
nents should be recuperated ecologically.
The cooling circuit is full of refrigerant that
should be recuperated and returned to the
gas manufacturer for recycling.
Oil will remain in the hermetic compressor
and, therefore, must be returned with the
circuit sealed.
The air conditioning unit will be deposited in
an area determined by the local authorities
for its selective recuperation.
Safety
Installation and maintenance servicing of this
air conditioning system should be carried out
by qualified and expert personnel only.
Maintenance servicing, such as cleaning coils
and air filters, should be carried out regularly to
maintain optimum performance of the units.
Caution
This unit should be installed and
used in compliance with:
- Low voltage electro technical
regulations.
- Safety regulations for cooling plants and
installations.
- Pressure device regulations.
- Basic building regulations.
- Local regulations.
Transportation
The units should always be transported in
vertical position so as to avoid oil dripping
from the compressor.
If, for any reason, this position need be
changed sporadically, they will remain in
that position a strictly necessary period of
time only.
Warning signs
The following signs indicate the existence of
potentially dangerous conditions for users or
maintenance service personnel. Whenever
found on the unit, take the meaning of each
one into account.

Attention: Possible gas leak due to inad-
equate handling.
Location of VIR 25 to 90A in-
door units
Locate the unit preferably near a wall lead-
ing to the exterior so as to make installation,
maintenance and draining easier.
Location of VCH 20 to 90A out-
door units
The location of these units should be chosen
anticipating a permanent access for main-
tenance servicing, either through the side
panels or the rear panel.
The outdoor unit can be installed directly in
exteriors. If installed in interiors, basements,
attics, etc., the outdoor air and extraction
ducts must be connected.
When installing in interiors, keep in mind that
in the summer operating cycle, the outdoor
coil condenses a large amount of water that
must be evacuated through the drain.
The possibility of an obstruction of the drain
by foreign elements, dust or dirt.
Areas where it snows regularly. If the unit
is installed outdoors and at ground level, it
should be raised on supports so as to avoid
accumulations of snow obstructing air flow.
These supports should be above the height
the snow reaches normally. It is convenient
to install anti-snow grids.

Fastening the indoor unit to
the ceiling
When fastening, make sure it is completely
horizontal, or very slightly tilted towards the
drain, so as to avoid possible condensed
water leaks (use a bubble level).
It is extremely important to be very careful
with the support of the indoor unit on the
ceiling.
Make sure the ceiling is strong enough to
support the weight of the unit.
Before hanging, check the strength of each
suspension bolt installed.
Outdoor unit air ducts
1.- Connect the ducts, isolating them from
the unit by means of a flexible hose,
preferably of non-flammable material,
