U.E. CONNECTIONS / IU
2.1 GENERAL PROVISIONS
1) The HUB RADIATOR PACK CF system is designed for
to work exclusively with the indoor unit positioned inside
of the building to be heated and the booster outside the building
2.2 ELECTRICAL CONNECTIONS
Connect the cable to the electrical panel:
1) The connection cable of the indoor and outdoor unit must
be of the H07RN-F type.
2.3 INSTALLATION OF PIPES FOR THE R410A
REFRIGERANT
The main cause of refrigerant gas leaks is due
to a defect in the flaring. Make folders so
corrected respecting the following indications:
A) Cut the pipes and the cable (Fig. 1)
- Use pipes with measurements suitable for the unit installed, ie
3/8 ’’ - 5/8 ’’ for Booster HR 7.8 and 3/8 ”- 1/4” for Booster HR
3.0.
- Measure the distance between the indoor and outdoor unit.
- Cut the pipes to a length slightly greater than the measured
distance.
- Cut the electric cable 1.5 mt. longer than length of the tube.
B) Burr removal (Fig. 2)
- Completely remove all burrs from the section transverse of the
tube.
- The processing must be carried out with the end of the tube
downwards so that the burrs do not fall into the tube.
C) Flaring (Fig. 3)
Remove the nuts fixed on the internal and external unit, insert
them on the pipe and carry out the banding and removal of
burrs, such as previously indicated.
D) Placement of the nut Fix the copper pipe firmly with a nut of
the size i ndicated in table 2.
E) Fixing the connection (Fig. 4)
Align the tubes. Tighten the nut sufficiently and tighten it with
two keys as shown in the figure.
- Precautions Excessive torque can break the nut, respect
then the details reported in table 2.

2) During the installation phase it must be checked carefully
that the distance and the difference in height between the 2
units are in accordance with the data shown in table 3.
3) Before installation, check that the wall where you are
chosen to position the internal storage is able to
to hold the weight itself and the water contained in it
of exercise.
4) In case of replacement of an existing generator, carry out the
chemical washing of the plant and adding a special one
anti-algae additive.
5) When choosing to install the hybrid system
HUB RADIATOR PACK CF, is to be taken into consideration
the electrical absorption of the outdoor unit. Then set up
all the works necessary to adapt the electrical system
(meter, cable section, circuit breakers, etc,) to guarantee correct
operation and voltage constant between 220 and 240 V.
6) Check that any existing exhaust ducts have an adequate
draft, do not present bottlenecks e that do not create dangerous
situations. The type of fume evacuation must be of the approved
type in the phase of certification, as described in the
identification plate of the product. You must also check that in
the fireplace or no other exhausts are inserted in the flue
appliances, unless it is made expressly to serve more users in
compliance with legal requirements.
7) Check that the appliance is set up to work
with suitable fuel, as indicated on the plate e
packaging.
2) Turn the electrical panel to the right and remove the screws,
then remove the cover.
3) Connect the cables according to the markings.
Connect the cable to the external unit .
4) Remove the cover of the outdoor unit.
5) Connect the terminal cables according to the numbers on the
unit terminal board, respecting the sections shown in
table 1
6) Fix the cables so that they do not come in contact with parts
electric or metal
