PRESSURE REGULATOR
The pressure regulator holds water pressure at a preset
point and bypasses the excess water.
To adjust:
With the unit running, with the cleaning tool valve closed,
the pressure gauge should read 0. With the tool valve open,
adjust the pressure by turning the adjusting knob so that
the pressure gauge reads between 0 - 1500 PSI.
DO NOT loosen the adjusting body (cap) all the way
(counterclockwise) or remove it while the unit is running.
Lubricate the o-rings in the pressure regulator
every 100
hours
.
Use only o-ring lubricant (Part #13-003).
If you do not, the stem may become seized due to
inadequate lubrication. If this occurs:
1.
Shut down the unit.
2.
Relieve all pressure from the water system.
3.
Loosen the valve nut and remove the valve stem
with long nose pliers.
4.
Clean and lubricate stem.
5.
Reassemble pressure regulator.
6.
Check the port cap o-rings for proper lubrication as
well.
