2.1 GENERAL PROVISIONS

1) The MINI HUB RADIATOR system is designed
to work exclusively with the indoor unit
positioned within the building to be heated
and the booster outside.
2) During the installation phase it must be verified
carefully that the distance and the height difference
between the 2 units comply with the data reported
above this manual.
3) Before installation, check that the wall where you
have chosen to place the internal storage be able to
support the weight itself accumulation and the water
contained in it.
4) In case of replacement of a generator make the
system clean and the addition of a special anti-algae
additive.
5) When you choose to install the MINI HUB
RADIATOR system, there is to keep considering the
electrical absorption of the unit external. Then prepare
all the works necessary to adapt the electrical system
(counter, cable section, switches circuit breakers,
etc.,) to guarantee the correct operation and a
constant voltage between 220 and 240 V at the
power cables of the outdoor unit.
2.2 ELECTRICAL CONNECTIONS
Connect the cable to the electrical panel:
1) The connection cable of the indoor unit
and external must be of the H07RN-F type.
2) Lift the panel of the electrical panel e
remove the screws, then remove the cover.
3) Connect the cables according to the markings.
Connect the cable to the external unit:
1) Remove the cover of the outdoor unit.
2) Connect the terminal cables according to the
numbers present on the terminal board of the unit,
respecting the sections shown in table 1
3) Fix the cables so that they do not come into
contact with electrical or metal parts.
2.3 INSTALLATION OF THE PIPES FOR THE
REFRIGERANT R410A
The main cause of refrigerant gas leaks
is due to a defect in the flaring. Make
the folders correctly respecting the following
indications:
A) Cut the pipes and the cable (Fig. 1)
- Use pipes with adequate dimensions for the unit
installed (table 2).
- Measure the distance between the indoor and
outdoor unit.
- Cut the tubes to a slightly length greater than the
measured distance.
- Cut the electric cable 1.5 mt. longer than tube
length.
B) Burr removal (Fig. 2)
- Completely remove all burrs from the
cross section of the tube.
- Processing must be performed with the end of the
tube down so that the burrs do not fall into the tube.
C) Flaring (Fig. 3)
Remove the nuts fixed on the internal unit and
outside, put them on the pipe and carry out the
flaring and the removal of burrs, as previously
indicated.
D) Placement of the nut Fix the copper tube firmly
with a nut of the size indicated in table 3.
E) Fixing the connection (Fig. 4)
Align the tubes. Tighten the nut sufficiently e
tighten it with two keys as shown in the figure
- Precautions Excessive torque can break the
nut.
