Heat pump water heater – TECHNICAL INFORMATION FOR INSTALLERS
4. INSTALLATION
4.1 Location of the appliance
WARNING! Prior to starting any installation activities, ensure that the location where the water heater is to be
installed satisfies the following requirements:
a)
In the event of water heaters without an air exhaust duct, the room of installation should have a volume of
no less than 20 m
favour frost build-up. Do not install the product in a room containing an appliance that requires air to
function (e.g. an open-chamber gas boiler, open-chamber gas water heater, etc.). The product's safety
and performance levels are not guaranteed in the event of outdoor installation.
b)
The appliance's air exhaust and/or extraction duct (if present) must have access to the outside from the
point where the appliance is installed. The connections for the air exhaust and aspiration ducts are
located on the upper part of the appliance.
c)
Ensure that the installation site and the electrical and hydraulic systems to which the appliance must be
connected fully comply with the regulations in force.
d)
The chosen site must have, or must be suitable to house, a single-phase 220-230 V ~ 50 Hz power
supply socket.
e)
The chosen site must be suitable to house a condensate drainage outlet connected to the side of the
appliance with a suitable siphon.
f)
The chosen site must ensure that the appropriate safety distances from the wall and ceiling can be
observed, for the appliance to operate properly and to facilitate maintenance operations.
g)
The support surface must ensure a perfectly horizontal operating position (Refer to fig. 2).
h)
The chosen site must conform to the appliance's IP protection rating (protection against the penetration of
liquids) as specified by the regulations in force.
i)
The appliance must not be exposed to direct sunlight, even when windows are present.
j)
The appliance must not be exposed to particularly aggressive substances such as acidic vapours, dust or
gas-filled environments.
k)
The appliance must not be directly installed on telephone lines that are unprotected against overvoltage.
l)
The appliance must be installed as close as possible to the points of use to limit heat dispersion along the
piping.
m)
The air aspirated by the product must be free of dust, acicid vapours and solvents.
In the event of non-ducted installation, observe the distances from the walls as indicated in Fig. 4.
4.2 Positioning on the ground
Refer to Fig. 5
1)
Once the suitable installation position has been located, remove the packaging and remove the fixings
visible on the pallet where the product is based.
2)
Using the appropriate belt, remove the product from the pallet.
3)
Fix the feet on the ground (through the appropriate holes) using suitable screws and rawlplugs; after
positioning the appliance, remove the fabric belt by loosening the relative bolts.
4.3 Air supply connections
Please bear in mind that using air from heated environments may hamper the building's thermal performance.
There is one connection for the air intake and two for the air exhaust on the rear side of the appliance. It is important
not to remove or tamper with the two grilles and the cover (which bears the wording "Closed air" and is positioned by
factory default on the upper part of the product). The outlet air may reach temperatures that are 5-10°C lower
compared to that of the inlet air and, if not ducted, the temperature of the room of installation may drop sensibly. If the
and must be adequately ventilated. Avoid installing the appliance in rooms which may
