Please install the pressure limiter according to the water flow direction, do not
install it in the wrong direction, otherwise it will not work normally.
The pressure limiter is adjustable, you can use tools to rotate the cross slots to
change the feed water pressure relief. Please connect a pressure gauge to the outlet
and block the following pipe when you adjust the pressure. Then you need to regulate
slowly in accordance with the pressure gauge.
Do not rotate the regulator when you do not have any water pressure test
instrument.
