1.

Before installation, flush the pipes in order to clear any
contamination and prevent the build up of dirt.

2.

Install the safety group horizontally and install the ex-
pansion relief valve so that it is facing upwards.

3.

Note the flow direction, which is specified by an arrow.

4.

Connect the safety group

to the drain valve. Consult

the table below to find out the length to which the pipe
should be cut.

Note

If you have to set up a secondary return,
install the T-piece supplied for the VIH RW
GB 250 BES and VIH RW GB 300 BES
products.

5.

Install a pipe between the safety group's connection

(3)

and the temperature and pressure expansion relief

valve. Use a T-piece for this. The pipe system must
continuously slope downwards, must be visible and
must be protected against frost. There must be no risk
of injury to persons.

Tundish

The drain connections of the temperature and pressure re-
lief valve and the expansion relief valve must be connected
to the supplied tundish via 15-mm-thick copper pipes. The
tundish must be installed vertically, as close to the cylinder
as possible and with a maximum clearance of 600 mm from
the connection of the temperature and pressure relief valve.
It must be installed in the same room as the cylinder, but at
a sufficient distance from electrical components. The drain
pipes from the temperature and pressure relief valve and
from the expansion relief valve can be connected above the
tundish using a T-piece. The drain pipe from the 22 mm con-
nection of the tundish must consist of copper pipes with a
diameter of at least 22 mm and be connected to a safe and
visible drainage point. The vertical section of pipe beneath
the tundish must be at least 300 mm long before any bends
or diversions in the line. If the total resistance of the drain
pipework exceeds the values in the following table, you must
increase the diameter of the pipework. When installing the
drain pipework, comply with the standards, directives and
laws that are applicable in your country.
