controlled" 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 GAHP-A LT technical data
→
11 or
Table 3.2 GAHP-A HT technical data
→
13.
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 "SUP-
PORTS and LEVELLING" below).
The structure of the building must support the total weight of the appliance and the sup-
porting base.
The weight of the appliance is given in Table 3.1 GAHP-A LT technical data
→
11 or Table
3.2 GAHP-A HT technical data
→
13.
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 vibrations of limited intensity, the use of antivibration
mounts (available as accessories, see Section 8 ACCESSORIES
→
77) is strongly recom-
mended in such cases of installation on roofs or terraces in which resonance phenomena
may arise.
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.
sUPPoRts And LeVeLLInG
The appliance must be correctly levelled by placing a spirit level on the upper part.
If necessary, level the appliance with metal shimming; do not use wooden spacers as
these deteriorate quickly.
CLeARAnCes And WARnInGs
Position the appliance so as to maintain minimum clearances from combustible sur-
faces, walls or other appliances, as illustrated in Figure 5.2 Clearances
→
30.
Minimum clearances are required for maintenance accessibility.
The fumes outlet terminals must be installed in such a way that they do not allow the
fumes to collect or return to the circuit in the unit's installation area. The outlet terminal
must be constructed in conformity with established regulations.
Do not install any cover or obstruction to the evacuation of the air issuing from the fan.
When deciding on the installation position, especially if multiple units are used, consider
that each unit requires 11,000 m
3
/h of air for the coil. Make sure that the installation and
position allow for sufficient air flow to the coil and prevent recirculation, which would re-
duce efficiency and shut-down the appliance of the units and force them to switch off.
