during winter operation, the appliance, on the basis of temperature and humidity
conditions of the outside air, can carry out defrosting cycles that cause the layer of
frost/ice on the fan coil to melt.
Take this possibility into consideration, adopting appropriate measures (for
example: a containing step and channeling of water into a suitable drain) in order to
prevent uncontrolled spread of water around the appliance and the consequent risk
that a dangerous layer of ice will form.
The manufacturer may not be held responsible for any damage arising from
the failure to observe this warning.
¾ Installation at ground level
If a horizontal support base is unavailable (see also "SUPPORTS and
LEVELLING" on page 30), it is necessary to create a flat level base in concrete
which is larger than the dimensions of the base of the appliance by at least 4÷6”
on each side.
The dimensions of the appliance are given in Table 4, page 10.
Provide a “containing” step and a suitable drainage channel for the water.
Figure 7 – Suggested dimensions of the unit bed.
¾ Installation on a terrace or roof
Position the appliance on a leveled flat surface made of fireproof material (see
also "SUPPORTS and LEVELLING" - page 30).
The structure of the building will have to support the weight of the appliance
added to the weight of the supporting base.
The weight of the appliance is given in Table 4, page 10.
Create a “containing” step and a suitable drainage channel for the water,
providing a gangway around the appliance for maintenance purposes.
