Maintenance
Pressure Regulator
The pressure regulator serves to maintain water
pressure at a preset point and to bypass water back to
the water box.
To adjust:
1.
With your unit running, close the cleaning tool
valve. Check the pressure gauge. Open the tool
valve. We recommend setting the pressure
regulator so that the pressure gauge reads 450
PSI with the tool valve open.
When the tool valve is opened, there is an approxi-
mate drop of 50 PSI in pressure. If there is a
pressure drop greater than 100 PSI, it may be
necessary to lubricate the o-ring in the pressure
regulator.
2.
If the pressure regulator requires adjustment,
loosen the locking nut, then turn the adjusting body
(cap) (while observing the pressure gauge on the
control panel) until the desired pressure is
obtained. Retighten the locking nut.
DO NOT
loosen the adjusting body (cap) all the way
(counterclockwise) or remove it while the unit is
running.
NE PAS desserrer complètement le boîtier de
réglage (capuchon) (dans le sens contraire des
aiguilles d'une montre) ou le retirer alors que
l'appareil est en marche.
We recommend that you lubricate the pressure
regulator o-ring every
50 hours
, or whenever required.
If you do not, the stem may become seized due to inad-
equate lubrication. If this occurs:
a.
Shutdown the unit.
b.
Relieve all pressure from the water system.
c.
Remove the cap from the pressure regulator and
remove the stem with long nose pliers.
d.
Clean and lubricate stem.
e.
Reassemble pressure regulator.
