APPLIANCE POSITIONING
Do not install inside a room
The appliance is type-approved for external installation.
▶
Do not install inside a room, not even if it has openings.
▶
In no event start the appliance inside a room.
K18 Hybrigas unit ventilation
▶
The aerothermal appliance requires a large space, ventilated
and free from obstacles, to enable smooth flow of air to the
finned coil and free air extraction from the fan outlet, with
no air recirculation.
▶
Incorrect ventilation may affect efficiency and cause dam-
age to the appliance.
▶
The manufacturer shall not be liable for any incorrect choic-
es of the place and setting of installation.
Limiting heat loss
▶
It is advisable to place the unit near the inlet of the water
pipes in the building, minimising the external sections (ad-
equately insulated), in order to avoid unnecessary heat loss.
Where to install the appliance
▶
The appliance may be installed at ground level, on a terrace
or on a roof, compatibly with its dimensions and weight.
▶
It must be installed outside buildings, in an area of natural air
circulation. It does not require protection from weathering.
▶
No obstruction or overhanging structure (e.g. protruding
roofs, canopies, balconies, ledges, trees, etc.) must interfere
either with the air flow reaching the finned coil and leaving
the front part of the appliance or with the fumes exhaust.
▶
The appliances flue gas exhaust must not be immediately
close to openings or air intakes of buildings, and must com-
ply with environmental and safety regulations.
▶
Do not install near the exhaust of flues, chimneys or hot
polluted air. In order to work correctly, the appliance needs
clean air.
Defrosting water drainage
In winter, it is normal for frost to form on the finned coil
and for the appliance to perform defrosting cycles.
▶
To prevent overflowing and damages provide for a drainage
system connected to water discharge (reference E Figure
p. 10).
Acoustic issues
▶
Pre-emptively assess the appliance's sound effect in connec-
tion to the site, taking into account that building corners, en-
closed courtyards, restricted spaces may amplify the acous-
tic impact due to the reverberation phenomenon.
2.4
MINIMUM CLEARANCE DISTANCES
Distances from combustible or flammable materials
▶
Keep the appliance away from combustible or flammable
materials or components, in compliance with applicable
regulations.
Clearances around the appliance
The minimum clearance distances shown in Figure 2.3
(bar any stricter regulations) are required for safety, operation
and maintenance.
An open area of at least 2.5 m must be guaranteed above the
appliance so as to allow free air circulation, as shown in Figure
Figure 2.3
