The FrostControl must be installed in the cold water supply.
Any pressure or immersion pumps up to 2.8 bar can be used
to operate the water supply.
On the boiler, the FrostControl replaces the manually operated
drain valve.
Figure 4
To allow safe drainage of the boiler contents if there
is a risk of frost, an automatic aeration valve must be
installed at the boiler’s hot water connection. Standard on all
Truma hot water units.
Figure 5
Water removal can take place directly to the outside in a
splash-protected location (fit splash guards if necessary).
Before starting work, read through the installation and oper-
ating instructions carefully to understand how to install the
product.
