ATTENTION
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 P&T 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. When the flexible drainpipe is joined to the pressure relief
orifice of this valve, you must ensure that the flex
i
ble drainpipe is pointing downwards
and exposed in the air.
