PRESSURE REGULATOR
The pressure regulator holds water
pressure at a preset point and bypasses the
excess water back to the water box.
To adjust:
1. With the unit running, close the
cleaning tool valve. Check the pressure
gauge. Open the tool valve. Set the
pressure regulator so that the pressure
gauge reads 450 PSI with the tool valve
closed. With the tool valve open, there
should be a normal drop
in pressure.
If
the drop is greater than 100 PSI, it may
be necessary to lubricate the pressure
regulator o-rings.
2. To adjust the pressure regulator,
turn
the adjusting knob (while observing the
pressure gauge on the control panel) until
you reach the desired pressure.
!
DO NOT loosen the adjusting body
(cap) all the way (counterclockwise) or
remove it while the unit is running.
We recommend that you lubricate the
pressure regulator o-ring every
100
hours
, or whenever required. If you do
not, the stem may become seized due to
inadequate 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
