WEIGHT DISTRIBUTION

POSITIONING

The units have been designed for outdoor installation in a fixed position.

Check that the fastening/support points are in level and can bear the weight of the unit (see weights and weight distribution).

Avoid installation in areas that may be subject to flooding.

Installations below ground level or near very high walls must be carefully assessed.

Place a layer of rubber between the base of the unit and the support to prevent noise and vibrations. Depending on the place of
installation (balconies or roofs), the unit should be placed on special antivibration mounts (in this case, flexible joints are required for
the water/aeraulic connections - joints are not supplied by Clivet).

Fasten the unit to the ground.
The choice of the location of the unit is of fundamental importance for correct operation. Obstacles that block the flow of air, difficulty

in air circulation, leaves or other objects that may block the exchanger coils, winds that contrast or excessively assist the air flow,
phenomena of stratification or air re-circulation and nearby sources of heat, can cause operating anomalies (increases in condensing
pressure, and consequently decreases in performance) or the shut-down the machine (due to high pressure).
