PACKING NUT ADJUSTMENT FOR
CHEMICAL METERING, FLOW
SIMULATOR AND CHEMICAL
SELECTOR VALVES
Examine the packing nut on the chemical metering,
flow simulator, and chemical selector valves for
proper tension every 200 hours. When turning the
knob, there should be a small amount of resistance.
If not, slightly tighten the packing nut. DO NOT over-
tighten. Keeping the valve packings properly
adjusted will eliminate possible leakage from the
valve stems and add to overall valve life.
PRESSURE REGULATORS
The pressure regulators hold water pressure at a
preset point and bypass excess water back to the
water box.
LOW PRESSURE REGULATOR
To adjust:
1. With your unit running, close the cleaning tool.
Check the pressure gauge. Open the tool valve.
We recommend setting the pressure regulator
so that the pressure gauge reads 350 PSI with
the tool valve open.
When the tool valve is opened, there is an
approximate drop of 100 PSI in pressure. If
there is a pressure drop greater than 100 PSI,
it may be necessary to lubricate the o-rings
in the pressure regulator.
2. If the pressure regulator requires adjustment,
turn the adjusting knob (while observing the
pressure gauge on the control panel) until the
desired pressure is obtained.
HIGH PRESSURE REGULATOR
To adjust:
Set the high pressure regulator to desired pressure,
up to 3000 PSI. Adjust as necessary to meet you
cleaning needs.
Wiring Harness:
EVEREST EFI 980197 06/30/04
1. If you find it necessary to disconnect the
Amp connectors joining the harness to the
ECU, be sure to apply dielectric grease gel
to the female Amp connector prior to re-
connection.
