Pressure regulating valve:
This unit is equipped with a pressure regulating valve which prevents damage to
the unit by keeping the system pressure safely below a desired limit. When the system pressure exceed the
setting of the valve spring, the fluid unseats the valves and bypasses to the reservoir.
Pressure switch:
This unit is also equipped with a pressure switch which prevents the operation of the burner,
if adequate water pressure is not detected at pump. Keeping the burner off when there is no water flow will
eliminate the potential risk of steam generation and explosion. Also it turns on the timer function of the unit.
(Applicable models only).
Timing device (SHW78 & SHW78/S ONLY):
This unit is equipped with a pre-set timing device. The timer will
shut down the unit if it is left in bypass for longer than 5 minutes
.
Safety valve
: This acts as a fail-safe system. When the system pressure exceeds the set value, the valve
opens proportionally with increase in pressure and release the excess pressure out and resets back.
