Pipeline connection explanation
Installation of the water inlet or outlet pipes: The specification of the water inlet and
outlet thread is BSP3/4(internal thread).pipes must be heat-resistant and durable.
Installation of the pipe for Pressure release valve: The spec of the valve connecting
thread is BSP3/4(internal thread).After installation, it must be confirmed that the
drainpipe outlet is exposed in the air.
drainpipe is joined to the
pressure relief orifice of this valve, you must ensure that the flexble drainpipe
and exposed in the air.
When the flexible
is
pointing downwards
ATTENTION: The Pressure release valve attached with the unit must be installed,
will cause damage to the unit,
.
failure to do so
and possible personal injury
Do not use stainless steel fittings to connect directly with other metals to prevent
