2. CONNECTIONS U.E. / U.I.
2.1 GENERAL PROVISIONS
1) The HUB RADIATOR MINI XL 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.
5) Connect the terminal cables according to the numbers on the
unit terminal block, respecting the sections shown in table 1
6) Secure the cables so that they do not come into contact with
parts electric or metal.
2.3 INSTALLING THE PIPES FOR THE REFRIGERANT R410A
The main cause of refrigerant gas leaks is due to a defect in the
flare. Carry out the folders correctly, respecting the following
indications:
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

B) Removal of the burr (Fig. 2)
- Completely remove all burrs from the section cross section of
the tube.
- The processing must be performed with the end of the tube
down so that burrs do not fall into the tube.
Burr removal Fig. 2
C) Flaring (Fig. 3)
Remove the nuts fixed on the indoor and outdoor unit, insert them
on the pipe and perform the flaring and removal of the burrs, as
previously indicated.
Folding Fig. 3
D) Fixing the refrigeration pipes (Fig. 4)
Align the pipes by lubricating the external surface of the pipes in
correspondence with the flare. Sufficiently tighten the nut using
two wrenches.
Fixing
Precautions
Excessive torque can break the nut or crack the folder. to
avoid such dynamics, use a suitable torque wrench respecting
the tightening torque shown in table 3.
