Operating principle
A thermostatic element (1) in contact with the ambient air controls a shut off obturator fitted to
a passage seat in contact with the water contained in the pipe (2).
When the ambient temperature drops to the minimum intervention value, the thermostat
contracts. This causes the obturator to move and open a tiny passage so that water can drain
out, allowing a small amount of water to flow in continuously; this prevents water from freezing
inside the pipe.
Water from the supply network, which is usually warmer than the air temperature up to the
intervention value, laps the thermostat and causes the opposite action: the channel closes
again and normal circuit operating conditions are restored.
For optimal system operation without the risk of freezing, it is recommended that the part of
the circuit in which the safety device is installed is connected to the water supply network and
a suitable pressure level maintained.
Volume of water drained
While the anti freeze device is in operation, the drain outlet will drip as a result of the cyclical
opening and closing phases taking place correctly. The amount of water drained out varies in
accordance with the outdoor temperature, the temperature of the water in the pipe and the
length of piping exposed to the air.
As a general guide, in the worst case conditions, the amount of water drained out is less than
0,5 l/h.

Installation
Before installing the device, make sure that the system has been flushed and cleaned to
remove any traces of dirt that may have accumulated during installation.
The device must only be installed in vertical position, as shown in the diagram, so as to permit
a free and unrestricted downward flow of the water as it drains out.
The device must be
installed at the points of
the circuit which are at
risk of freezing, so that
water may flow freely
and in order to prevent
pipes, storages or
components located
upstream of the device
from freezing.
Installation on a dead leg is advisable for avoiding any risk of damage of the device caused
by overheating from the solar collector, in case of stagnation conditions.

The device must be installed by a licensed plumber in accordance with
national regulations and/or relevant local requirements.
If the device is not installed, commissioned and maintained properly,
according to the instructions contained in this manual, it may not operate
correctly and may endanger the user.
Make sure that all the connecting pipework is water tight.
When making the water connections, make sure that the device connecting pipework is not
mechanically over stressed. Over time this could cause breakages, with consequent water
losses which, in turn, could cause harm to property and/or people.
In the case of highly aggressive water, arrangements must be made to treat the water before
it enters the device, in accordance with current legislation. Otherwise the device may be
damaged and will not operate correctly.
