Prime/Pressure Relief Valve (Prime/PR Valve)
Used to relieve pressure from gun, hose & tip and to prime
the unit when in OPEN position. (It is in open position
when there is a wider gap
between valve handle and
cam body).
When in CLOSED position,
there is only a very slight gap
between handle & body.
When closed the system is
pressurized.
Handle as a loaded firearm!
1. Connect the hose and gun.
a. Remove the plastic cap plug from the outlet tee
and screw a conductive or grounded 3000 psi
airless spray hose onto fluid outlet.
b. Connect an airless spray gun to the other end of
the hose.
c. Do not use steel braided airless hose. Use nylon
braided airless hose only.
NOTE: Do not use thread sealer on swivel unions as
they are made to self-seal. Use thread seal on
tapered male threads only.
3. Check the Electrical Service.
Be sure the electrical service is 120 VAC, 15 amp
minimum, and that the outlet you use is properly
grounded.
