INSTALLATION & OPERATION
WARNING
This valve is for use ONLY in low pressure circulat-
ing systems. To reduce the risk of serious bodily
injury, which could result from over-pressurizing
and rupturing the valve, NEVER supply more than
300 psi (21 bar) fluid pressure to the valve.
To reduce the risk of splashing, always relieve the
air and fluid pressure to the gun before removing
this valve for any reason.
Connect the circulating fluid hoses to the valve.
Connect the valve to the gun.
For twist-lock couplers, align the pins on the stem with
the coupler slots and push the coupler onto the stem.
Turn the stem clockwise to lock it.
To adjust the fluid flow, insert the adjustment tool (A) as
shown in Fig 1. Turn the tool clockwise to decrease flow
and
counterclockwise to increase flow.
