SAFETY: Please read the directions carefully before to set the unit going, in order to avoid accidents and damages in the
plant caused by an incorrect use of the product. Keep this manual for future consultations.
(A) all valve on the return way
(thermoter with blue ring and scale
0-120°C) with “Solar” checkball.
Solar Checkball
It is included into the ball valve.
It ensures the seal and low head
losses. To exclude the checkball valve,
for instance in case of emptying rotate
the handle by 45° clockwise.
(D) Circulating pump
Three speed circulating pump
with manual regulation. Thanks
to the seal of the ball valves
before and after the circulating
pump, it can be removed without
emptying the installation.
Back plate to fasten the unit
to the wall or to the cylinder.
(B) Security unit
The security unit, CE and TÜV
approved, protects the installation
from the overpressures. It is
calibrated at 6 bar, over this
pressure the security unit starts. It is
also provided with a manometer
and with a connection to the
expansion vessel by a 3/4" flexible
kit (optional), see here below.
(C) Flowmeter
The flowmeter allows to regulate the flow rate to the capacity
of the installation, by a 3-way ball valve. If the valve is closed
the usual circulation is cut off, it is possible to use the side
filling tap to fill the installation.
There is also another side tap, for the draining.
The proximity of the two taps helps these operations
minimizing the distance between the filling and the draining.
The flow rate is measured and shown by the special sliding
cursor: the measurement is immediate thanks to the proximity
to the regulation valve.
As shown hereinunder four flowmeters are available with
different intervals of measurement:
1-6 l/min, 2-12 l/min, 8-28 l/min and 8-38 l/min.
Seat for the
course of the
cable going to the
circulating pump.
Epp insulation box
Measurements 150x425x150.
Box with a special bracket to fasten the unit and
with the groove for the cable.
Cover with the opening for the cable press. (The
cable press must be positioned towards the
down, see the picture). Side opening for the
security unit. A special window allows to read and
to regulate the flow without removing the cover.

Housing seat of of the controller.
At the side there is a passing hole that
allows the wiring to reach the circulating
pump. The passing hole for the sensor
and for the outside of the insulation box.
(1) - Filling the installation:
Remove the plugs from the side valves and
connect the hose unions. Close the ball
valve and open the side filling valve and
draining valve.
(2) - Starting the installation working:
Open the ball valve and close the side filling and draining valves.
Remove the hose unions and screw again the plugs.
To avoid any casual opening of the side valves, it isbetter to stop the
levers in the close position, as shown here aside.

Regulation of
the flow rate
(3) - Regulate the flow rate using the regulation
rod until the right flow rate is shown.
N.B. The flow rate is shown taking as reference
the lower edge of the sliding cursor. (see
picture)
Flow rate shown
(in this case
8 L/min)
Directions for the use of the flowmeter to fill the installation:
Blocking the filling/drain
levers:
Unscrew thefixing screw,
take out thelever andplace
itagain turning it of 180°.
TAKE CARE: as regards the installation and the working of the controller, please look to the here enclosed manual.
