NOTE: Individual components for the ball valves are
not available.
NOTE: Ball valve nut threads have thread sealant ap-
plied during initial assembly. Nut removal may be diffi-
cult.
10.If needed, disassemble ball valve using Fig. 27 as a
guide.
Installation (Fig. 25)
1. If ball valves were disassembled, assemble ball
valves using Fig. 27 as a guide. Torque nut 45 to 55 in–lb
(5.1 to 6.2 N–m).
NOTE: When assembling ball valves and lever to ball
valve bracket, make sure that valve ball is orientated to
upper fitting opening of ball valve assembly and lever is
in the paint (lowered) position.
2. Position ball valves and lever to ball valve bracket.
IMPORTANT: Install fittings into ball valves by hand
to prevent cross–threading the ball valve threads.
3. Apply Saf–T–Lok PTFE Pipe Sealant (or equivalent)
to threads of all removed fittings (see Thread Sealant for
Paint System Fittings in the General Information sec-
tion). Install fittings to ball valves as follows:
A. Tighten recirculation port (item 24) so that clear-
ance between port neck and top of bracket is from
0.000" (flush) to .030" (.0 to .8 mm) (Fig. 28).
B. Tighten outlet port (item 7) so that clearance be-
tween bottom of hex and top of bracket is from 0.000"
(flush) to .030" (.0 to .8 mm) (Fig. 28).
C. Torque remaining fittings to value identified in Fig.
25.
4. Place new rubber washers (item 6) on ball valve
ports. Position ball valve assembly to machine.
5. Install two (2) flange screws (item 16) that secure ball
valve assembly to tank support but do not fully tighten.
6. Install washers (items 4 and 5), jam nuts (item 2) and
elbow fitting (item 3) that secure ball valve fittings to
paint tank. Tighten jam nuts. Torque elbow fitting from
144 to 156 in–lb (16.3 to 17.6 N–m).
7. Tighten two (2) flange screws (item 16).
8. Install hoses to fittings on ball valves (Fig. 26) (see
Quick Disconnect Fitting in the General Information sec-
tion).
9. Install knob (item 19) to lever.
