Installation Instructions

Inspection
Upon reception, inspect the goods and no-
tify the carrier and the insurance company,
in writing, of any possible damage during
transportation.
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 car-
ried 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. If, for any reason, this posi-
tion 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 us-
ers or servicing personnel. Whenever found
10
on the unit, take the meaning of each one
into account.

Caution: The unit is equipped with a remote
control system and can start up automati-
cally.
Before accessing the interior of the unit,
disconnect the power supply so as to avoid
any contact with the fan turbine in motion.

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.
Clearances
When installing each unit, clearances should
be left for:
a) Air intake and discharge of the unit.
b) Connection of the train pipes and wir-
ing.
c) Air ducts.
d) Maintenance servicing.
e) Power supply connections.

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 ceil-
ing. Make sure the ceiling is strong enough
to support the weight of the unit.
Before hanging, check the strength of each
suspension bolt installed.
Indoor unit air ducts
1.- Connect the ducts, isolating them from
the unit by means of a flexible hose,
preferably of non-flammable material,
so as to avoid the transmission of vibra-
tions of the unit. If the ducts are made
of flexible material, they do not transmit
vibrations.
2.- It is recommendable to install a damper
at each by-pass of the discharge duct
for the purpose of carrying out a correct
balance of the system.
3.- Leave easy access for cleaning and
changing the air filters.
Drain connections, VIR 25 to
90A indoor unit drainage
It is necessary to connect a condensed wa-
ter drain pipe to the evaporating unit.
Install the drain pipe through a siphon. Leave
a minimum level distance of 25 mm. between
the height of the unit connection and the line
after the siphon.
An access must be left so as to fill the
siphon with water at the beginning of each
season.
The drain line must have a minimum slope
of 2 cm. per each metre in length.
Insulate the condensed water drain pipe so
as to avoid leaks and damaging the floor.
Drain pipe insulation
Insulate the condensed water drain pipe so
as to avoid leaks and damaging the floor.
Make sure water evacuation is being carried
out correctly.
Interconnecting units
The installation of a unit compris-
es:
- Assembly of the unit.
- Connection of refrigerant pipes.
- Wiring of the unit.
When installing Split units, make sure the
cooling circuit is completely sealed after as-
sembly, for the purpose of avoiding leaks.
This will contribute to achieving maximum
performance with minimum consumption,
��� and will avoid serious damage to the unit.
Furthermore, this is an ecological precau-
tion.
Installation of interconnecting
pipes
The length of the interconnecting pipes of
