6.3.2 Strainer
Strainers should be cleaned regularly by authorized personnel. The
frequency of cleaning would depend on operating conditions and
the manufacturer's instructions.
6.3.3 GTU Pressure Equalizer
The GTU Pressure Equalizer absorbs the expansion on the
secondary side of the Termix water heaters and can be used as a
substitute to the safety valve.
Furthermore the pressure equalizer absorbs a possible increase in
pressure, so a discharge outlet is omitted.
The GTU Pressure Equalizer may not be applied in systems with hot
water circulation.
