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
It is forbidden to touch the device while barefoot or with
wet or moist body parts.
0
It is forbidden to perform any technical or cleaning opera-
tions before having disconnected the device from its elec-
trical power supply, by setting the system's main switch to
"off".
0
It is forbidden to pull, detach, or twist the electrical cables
protruding from the device, even if it is disconnected from
its electrical power 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 fittings (expan-
sion vessels, pipes, insulation) that are not specifically de-
signed and tested for use in solar water heating systems.
0
Do not allow children or infirm 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.

DESCRIPTION OF THE APPLIANCE
The solar station
RSS
allows transferring sun power from collec-
tors to a storage system.
The solar station
R
is enclosed in an EPP (Polypropylene foam)
insulating casing and is designed to perform:
− system flushing
− system filling and emptying
− circulator removal.
The key components are:
− high-efficiency circulator with variable speed (already
hard-wired)
− shut-off valves as non-return valves
− thermometers
− pressure gauge
− fitting for connection to a solar expansion tank
− suitable safety device, as indicated in paragraph "Safety
and control devices".
Version MRS includes a solar regulator and temperature probes
as standard (to be connected). Version MR includes a terminal
strip for interface connection to an external regulator able to
manage one PWM pump.

The integrated circulator can be managed only through
PWM signal and does not need a flow control. Therefore,
to choose the proper solar regulator to match version MR
please refer to paragraph "Electric connections and wiring
diagrams”.

SAFETY AND CONTROL DEVICES
Solar station safety and setting are achieved thanks to:
− Safety valve with trigger pressure set at 6 bar;
− Solar Regulator (if equipped) for circulator management/
control. Manages 9 system diagrams that can be select-
ed. Refer to the specific manual for further details.
