INSTALLATION AND CONNECTIONS
WARNING! Installation, commissioning
and maintenance of the device must be
performed by qualified and authorised
personnel. Do not attempt to install the
device yourself.
5.1
Preparation of the installation site
The installation of the device must be carried out in a
suitable place in order to allow the normal use and
adjustment operations, together with ordinary and
extraordinary maintenance to be performed.
Therefore it is important to allow for the necessary
working space by referring to the dimensions shown in
Fig. 1.
Fig. 1 – Minimum space
Moreover, the premises must:
Have adequate water and power supply lines;
Be available and ready with adequate
discharge pipes in case of damage caused to
the boiler or actuation of the safety valve or
breakage of pipes/connections;
Have containment systems in case of serious
water leaks;
Be sufficiently lit.
5.2
Ventilation connection
For a correct operation, the heat pump requires
adequate ventilation. It is necessary to create a
dedicated air duct as indicated in the following
illustration (
Fig.
2
).
Fig. 2 – Possible air outlet ducts
To ensure an adequate ventilation of the heat pump, the
spaces indicated in the paragraph 5.1 must be
respected.
Carry out the installation of the air duct taking care that:
The weight of such does not adversely affect the
equipment itself;
Maintenance operations can be carried out;
This is adequately protected so as to avoid the
accidental intrusion of material inside the equipment
itself;
It doesn’t exceed the maximum suggested length of
6 meters.
The connection to the outside must be made with
suitable non-flammable pipes.
The total equivalent length of the exhaust piping plus
the delivery piping, including grilles, must not exceed
10 m.
