Fluid Line Accessories (Refer to Fig. 1)
1. Install a fluid filter (S) and drain valve (R) at the
pump outlet. Filtering the fluid will help remove
coarse particles and sediment that could clog the
spray tip.
WARNING
INJECTION HAZARD
The fluid drain valve (R) is required in
your system to assist in relieving fluid
pressure in the supply system, hose and
gun; triggering the gun to relieve pressure may not
be sufficient. Install a drain valve close to the
pump’s fluid outlet. The drain valve reduces the risk
of serious injury, including fluid injection and
splashing in the eyes or on the skin.
2. Install a fluid regulator (J) on the fluid line to con-
trol fluid pressure to the gun.
