GENERAL INFORMATION
GENERAL INFORMATION
9 Size the solar expansion tank so as to ensure complete ab-
sorption of the expansion of the uid contained within the
system, with reference to the prevailing regulations on the
matter. In particular, consider uid characteristics, consid-
erable uctuation of service temperature and vapour that
might be generated during solar collector stagnation stage.
Proper size of expansion tank ensures setting off of all vol-
ume changes of the heat transfer uid, avoiding excessive
pressure increase. Limited pressure changes avoid reach-
ing safety valve opening pressure and the consequent uid
drainage.
2 PRECAUTIONS
The operation of any appliance that uses electrical power de-
mands that a number of fundamental safety precautions be re-
spected. In particular:
0 Never attempt to install the system without using suitable
personal protection equipment and without following all
applicable occupational safety standards.
0 Do not touch the product when barefoot or wet if it has any
electrical accessories installed in it.
0 Never clean or service the storage cylinder without rst
turning the mains power switch OFF to disconnect all elec-
trical accessories (if tted) from the mains electricity supply.
0 Never pull, disconnect, or twist any electrical cables coming
from the appliance even if it is disconnected from the mains
electricity supply.
0 Do not expose the storage cylinder to the elements. It is not
designed for use outdoors.
0 If solar plant pressure decreases, it is forbidden to top up
with only water as there is a danger of freezing and over-
heating.
0 Do not use connections or safety devices or ttings (expan-
sion vessels, pipes, insulation) that are not specically de-
signed and tested for use in solar water heating systems.
0 Do not allow children or inrm persons to operate the sys-
tem unsupervised.
0 Do not dispose of packaging material into the environment,
or leave it within the reach of children, since it can become
a potential hazard. Dispose of packaging material in com-
pliance with applicable legislation.
3 DESCRIPTION OF THE APPLIANCE
R7200/3F HV PLUS solar tanks can be integrated into solar
systems to produce domestic hot water. They can also be paired
with heat pumps or boilers and heating units.
The most important technical features of these solar storage cyl-
inders are:
−special tank design and shape for optimum performance
in terms of stratication, heat exchange and replenish-
ment time
−Water ttings are available at different heights, permit-
ting different hot water generators to be used without
reducing the stratication effect
−insulation made of expanded polyurethane free from CFC
(chlorouorocarbons)
−the use of three anges, which means additional ex-
changers can be added
4 IDENTIFICATION
The R7200/3F HV PLUS solar heaters can be identied by:
Data plate
This lists the technical specications and performance of the
product.
Serial number plate
This species the serial number and model.
9 If these plates or any other means of clearly identifying
the product are defaced, removed or lost, proper instal-
lation and servicing may be rendered difcult.
9 On models 2000 and 3000 the technical data plate and
serial number plate must be applied (by the installer) af-
ter the insulation has been tted.

Vbu (*) The non-solar usable volume indicates the quantity of water (in litres) heated directly by the thermal integration coil. It
is calculated as the volume between the upper part of the heater and the lower part of the thermal integration element
(integration coil lower turn). The value shown in the tale refers to the coil located in the central part of the puffer. The
position of the coil can be changed and the volume changes as a result.
Vsol (**) The usable solar volume indicates the quantity of water (in litres) heated directly by the solar coil (placed in the lower
part of the heater) minus the non-solar volume (Vbu).

7 UNPACKING THE PRODUCT
R7200/3F HV PLUS solar heaters are supplied in a single pack-
age on a wooden pallet.
The insulation and cladding components on models 2000 and
3000 are supplied separately from the structural parts and should
be assembled when you receive the product, as described in the
section "Fitting the insulation (models 2000 - 3000)".
The following items are delivered in a plastic bag inside the
packaging:
−Instruction manual
−Bar code labels
−Hydraulic test certicate
9 The instruction manual is an integral part of the solar stor-
age cylinder. Once located, read it thoroughly and keep it
safe.
9 For handling operations, thoroughly follow the instructions
on device package label.
8 INSTALLING THE MAGNESIUM ANODES
Use the anodes provided; when assembling, note the position
and lengths provided in the technical data table.

−Partially remove the cladding, remove the washer and
unscrew the anode-holder plug in the sleeve using a
spanner
−Insert the anode provided, tighten the anode using a
spanner and then put the washer back in position.
7200/3F HV PLUS 2000 - 3000 models
−Before tting the cladding, unscrew the anode-holder
plug in the sleeve using a spanner
−Insert the anode provided and tighten the anode using
a spanner.
NOTE: Tighten the anode plug to a torque of 25-30 Nm.
9 FITTING THE INSULATION (MODELS 2000 - 3000)

14 RECYCLING AND DISPOSAL
The device is primarily composed of:
Material Component
carbon steel structural work
PU (polyurethane) insulation
PE (polyethylene) water connection washers
ABS (acrylonitrile-butadiene-styrene) covers
PVC (polyvinyl chloride) lining
At the end of the device's useful life, these components must be separated and disposed of according to current regulations in the
country of installation.
END USER INSTRUCTIONS
Refer to the GENERAL SAFETY INFORMATION and PRECAUTIONS section for safety-related information.
15 START-UP
The heater commissioning must be performed by Technical As-
sistance Service personnel.
Under certain circumstances, such as after long periods of dis-
use, the user may need to re-start it without involving the Tech-
nical Assistance Service. Before doing so, perform the following
checks and operations.
−Check that the supply cocks in the domestic water circuit
are all open
−Switch the electricity supply ON at the mains power
switch and at control panel switch (if tted).
16 TEMPORARY SHUTDOWN
To reduce to the environmental impact and save energy, in case
of brief absences, week-ends, short trips, etc., and with exter-
nal temperatures above 0°C, set the heater temperature control,
where available, to the minimum value.
9 If the temperature to which the heater is exposed can fall
below 0°C (frost hazard), perform the operations described
in paragraph "Preparing for extended periods of disuse".
17 PREPARING FOR EXTENDED PERIODS OF DISUSE
If the storage cylinder is not going to be used for an extended
period of time, ask the manufacturer’s Technical Assistance Ser-
vice to make the system safe.
18 EXTERNAL MAINTENANCE
Clean the outside of the storage cylinder with a soft cloth
damped in soapy water.
0 Do not use abrasive products, petrol or triethylene.
