are considered improper and are not permitted; in particular,
the use of the equipment in industrial processes and / or
installation in environments with a corrosive or explosive
atmosphere is not envisaged.
The manufacturer declines any liability for damage to
persons, animals or property resulting from non-compliance
with the instructions in this manual, from modications or
tampering with the product, from installation, adjustment,
maintenance errors and from improper use.
Failure to comply with what is indicated in this manual also
results in forfeiture of the warranty conditions.
1.7 SAFETY RULES
ATTENTION! Installation and maintenance must be carried
out exclusively by specialized and specially authorized
personnel.
The connection to the power supply must be performed in
accordance with current national plant standards.
During installation and maintenance operations, it is always
necessary to operate in conditions of maximum safety,
follow the instructions given in this manual and any warning
labels applied to the product.
Respect the installation and operating limits indicated in
this manual, never modify the internal electrical wiring and
refrigeration pipes, do not modify or disable the safety and
regulation devices.
Before any inspection, maintenance, or anything else
involving access to the internal parts of the appliance,
disconnect the general power supply.
In case of need or clarication for installation and maintenance,
contact a Technical Assistance Center authorized by A2B

2. CONNECTIONS U.E. / U.I.
2.1 GENERAL PROVISIONS
1) The HUB RADIATOR MINI system is designed to work
exclusively with the indoor unit positioned inside
of the building to be heated and the booster outside.
2) During the installation phase it must be carefully checked
that the distance and the difference in height between the 2
units comply with data reported in this manual (Table 4).
3) Before installation, check that the wall is where you
are chosen to position the internal accumulation to be able to
withstand the weight of the accumulation itself and of the water
contained in it.
4) In case of replacement of an existing generator carry out the
cleaning the system and adding a special anti-algae additive.
5) When you choose to install the system HUB RADIATOR MINI,
there is to be taken into consideration the electrical absorption
of the outdoor unit. Then arrange all the necessary works to
adapt the electrical system (meter, cable section, switches
circuit breakers, etc.) to ensure correct operation and a
constant voltage between 220V and 240V in correspondence
with the power cables of the outdoor unit. With voltage below
220V it is mandatory to install one voltage stabilizer able to
guarantee, the voltages allowed above, otherwise all types will
be void warranty.
2.2 ELECTRICAL CONNECTIONS U.E.
Connect the cable to the electrical panel:
1) The connection cable of the indoor and outdoor unit must be of
type H07RN-F.
2) Lift the electrical box panel and remove the screws, then
remove the cover.
3) Connect the cables according to the markings. Connect the
cable to the outdoor unit:
4) Remove the cover of the outdoor unit.

A) Cut the pipes and the cable (Fig. 1)
- Use pipes with suitable measures for the installed unit (Table 2).
- Measure the distance between the indoor and outdoor unit.
- Cut the pipes to a length slightly greater than
distance measured.
- Cut the 1.5 m electric cable. longer than the length of the tube
Taglio tubazioni Fig. 1
B) Removal of the burr (Fig. 2)
- Completely remove all burrs from the section cross section of
the tube.
