Setup
1. Connect the Hose and Gun
a. Remove the plastic cap plug from the outlet
tee and screw an accessory, conductive or
grounded spray hose onto the 1/4 npsm(f) out-
let fitting. See Fig 1.
b. Connect a small diameter, 3 ft (0.9 m) whip
hose between the main hose and a spray gun,
if desired, for more flexible gun movement.
c. Don’t use thread sealant on the swiveling nut
of the hose couplings, and don’t install the
spray tip yet.
NOTE: Use thread sealant on all male threads except at
swivel unions. Swivel unions are made to self–
seal, and using thread sealant prevents the
swivel from turning freely.
2. Fill the Packing Nut/Wet Cup 1/3 full with Graco
Throat Seal Liquid (TSL), supplied. See Fig. 2.
