4-18. WATER PRESSURE REGULATOR ASSEMBLY REPAIR - cont.
Ensure gasket is fully seated in groove of coupling
Install gasket (14) in female coupling (15)
Ensure that anti-seize tape is applied in the same direction as the treads
Ensure female coupling is installed on side of regulator marked "INLET"
Apply anti-seize tape to threads of female coupling (15) and nipple (17) Install female coupling (15) on
nipple (16) Install nipple and attached coupling on inlet side of regulator assembly (3)
Install one nut (9) and washer (8) on each of four threaded rods (10)
Position four threaded rods (10) and attached parts on board (11)
Rods should extended through bottom of board about 1/4-inch
Install threaded rods (10) on board (11) with four washers (7) and nuts (6) Adjust position of nuts (6 and 9)
on threaded rods so that rods extends about 1/4-inch below board
Install four nuts (5) and washers (10) on threaded rods (10)
Lower regulator assembly (3) onto threaded rods (10)
Install four washers (2) and nuts (1) on threaded rods (10)
Position four nuts (5) and washers (4) against bottom of regulator assembly (3), then tighten four nuts (1)
Adjust. Refer to figure4-12
Install regulator assembly in water system (hose and nozzle kit) (para 3-4a)
Startup water system (para 2-12c) and check regulator assembly for leaks
Squeeze distribution nozzle control lever (para 2-2) and allow water to flow
If water flow at distribution nozzle is not at desired pressure, loosen locknut (1) on regulator assembly (3).
Positioning adjusting screw so that seven threads are exposed above the locknut will provide a
good starting point for further adjustment
Turn adjusting (2) to the left to reduce water pressure or to the right to increase water pressure
