INSTALLATION I
CHOICE OF INSTALLATION SITE
Before installing the unit, agree with the customer the site
where it will be installed, taking the following points into con-
sideration:
• check that the support surface is adequate to support the
weight of the unit;
• respect safety distances between the unit and other equip-
ment or structures so that the fan air intake and outlet are
not blocked in any way.
• Follow the instructions shown in the chapter on DIMEN-
SIONED DRAWINGS to allow room for maintenance oper-
ations.
If installing multiple units the clearances must be doubled.
POSITIONING
• Install the vibration damping feet (accessories).
• Check the unit supports and weights before positioning
• Make sure that the unit is level, adjust the height of the
support feet if necessary
• Use the flexible joints supplied for the water connections
• Make sure there is easy access to the water circuit and
electrical parts
• For installation, if the site is exposed to strong winds, fix
the unit adequately using tie rods if necessary.
• In heating mode the unit produces a significant quantity of
condensate, which must be suitably drained.
Condensate drainage must not cause problems to objects
or people.
• If the outside air temperature is less than 0°C, the conden-
sate may freeze; in these case fit a frost protection heater
on the drain line.
• Consider the maximum height that may be reached by
snow to avoid blocking the air intake or outlet (outdoor
installation)
• Unit for outdoor installation
For correct operation of the unit, avoid the following:
• obstacles to air flow, such as leaves that may block the
heat exchange coil
• strong winds that stop or reinforce air flow
• sources of heat too close to the unit
• air recirculation between intake and outlet
• poor air change
• stratification of air
