1.10 Instructions for installation and connection of the unit
1.10.1 Characteristics of the location
Location of VIR 25A to 90A indoor units
Locate the indoor unit as close as possible to outdoor walls for easier installation, maintenance and
drainage. Make sure the ceiling fastening where the unit is located will withstand its weight.
The unit must be installed completely horizontally or sloping slightly towards the drain side.
Location of VCH 20A to 90A outdoor units
The location of the unit must be studied to ensure a completely satisfactory installation. To do so, the
environmental conditions of the area where the unit is to be installed must be taken into account.
Furthermore, the normal weather conditions should be instrumental in determining the best position of
the unit and the hoods, screens or covers required to ensure its correct working order.
If possible, in warm zones like the southern Europe, the unit should be located on the north or east side
of the building or property.
The location chosen for the unit must provide the condenser with an unlimited air supply.
As well as the technical data given in this document and any others that are applicable, please bear in
mind that the unit has been designed for outdoors installation only.
Where the unit is to be installed at ground level, refer to section
Fixture of the indoor unit to the ceiling
,
see on page 29.
Special instructions for locations where there is regular snowfall or with ambient temperatures of close
to 0 °C or less
In areas where there is regular or sporadic snowfall,
the unit must be elevated above the ground or roof
where it is installed. The height should be enough to
prevent the unit, the condenser and evaporator air
inlets and the access to the unit panels from becoming
blocked by accumulated snow.

With anti-snow grilles (high platform)
Protection against ice
In areas where the temperature can drop below 0 °C, there must be some kind of additional protection
to prevent the water in the condensate drain pipe from freezing.
