Pipe installation
The pipe installation must be carried out in accordance
with applicable standards.
Circulation pump
A circulation pump must be used to ensure the IJRZ over
the immersion heater. If the heating system valves can
close the circulation completely, the bypass valve must be
installed so that the
IJRZ through the electric heater does
not stop. In closed installations an approved safety valve
and pressure expansion vessel must be used.
NOTE
The pipe work must be IJXVKHG before the electric
heater is FRQQHFWHG so that any contaminants GR not
GDPDJH the component parts.
