The appliance can be installed at ground level, on a terrace or on a roof (if compatible with its “dimensions” and “weight”).
The dimensions and weight of the appliance are given in Table 3.1 p. 9 or Table 3.2 p. 10.
MOUNTING BASE
Always place the appliance on a levelled flat surface made of fireproof material and able to support the weight of the appliance.
In addition, provide a small “containing” step that will prevent water from spreading during possible winter defrosting phases.
During winter operation, the appliance (depending on temperature and humidity conditions of the outdoor air) can carry
out defrosting cycles melting the layer of frost/ice on the coil.
Take this possibility into consideration, adopting appropriate measures (for example: a“containing” step and channelling of water
into a suitable drain) in order to prevent "uncontrolled" spread of water around the appliance and the consequent risk that a layer of
ice will form (with the danger of falls on the part of passing people).
The manufacturer may not be held responsible for any damage arising from failure to observe this warning�
Installation at ground level
If a horizontal support base is unavailable (see also "SUPPORTS and LEVELLING" below), 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 100-150 mm on each side.
The dimensions of the appliance are given in Table 3.1 p. 9 or Table 3.2 p. 10.
Provide a “containing” step and a suitable drainage channel for the water.
Installation on a terrace or roof
Position the appliance on a levelled flat surface made of fireproof material (see also "SUPPORTS and LEVELLING" below).
The structure of the building must support the total weight of the appliance and the supporting base.
The weight of the appliance is given in Table 3.1 p. 9 or Table 3.2 p. 10.
Create a “containing” step and a suitable drainage channel for the water, providing a gangway around the appliance for maintenance
purposes.
Although the appliance produces only moderate vibrations, the use of anti-vibration supports is especially recommended in rooftop
and terrace installations in which resonance phenomena may occur.
Moreover, it is advisable to use flexible connections (anti-vibration joints) between the appliance and the hydraulic and gas supply
pipes.
Avoid placing the appliance on the roof directly above locals requiring quietness.
