LOW WATER PRESSURE
If the inlet water pressure gauge drops below 20 P.S.I. (1.4 BAR) (or out of the green zone) when the pump starts,
the pump will go into fault mode and will not start.
There must be between 20 PSI (1.4 BAR) and 90 PSI (6.2 BAR) of pressure available to the pump at all times
NOTE
: should the water pressure drop below the factory preset of 20 psi, the system goes to E06 “FAULT”. The
system will automatically try to restart after a 30 second delay. If the water pressure has been restored, the
system will continue running normally.
The BIGHORN pump incorporates a delay timer on the water pressure switch that allows the system to run for a
few seconds before going to alarm.
If the water pressure has not been restored, the system will attempt to start a further two times at 30 second
intervals. If the water pressure has still not been restored, the system will remain in fault and will need to be
manually reset.
To reset the unit; turn the MAN/OFF/AUTO switch to the “OFF” position and press the “Red/Green Button” on the
VFD panel one time and release. The system is now reset.
The setting on the water pressure-sensing switch is factory preset at 20 PSI / 1.4 Bar and does not require any
further adjustment.

SYSTEM RUN
Let the module run for five minutes making sure that there is a good flow of water running out the end of each
atomization line. Lines may have to be flushed in groups with a large system. The system is now ready for
pressurization.

PRESSURIZING THE SYSTEM
Safety glasses must be worn when adjusting pressure. Always keep guards and covers in place.
7.1
INSTALL DRAIN VALVES
Install the automatic drain valves, or plugs, into the open ends of the atomization lines. Use Teflon tape on NPT
threads and tighten each fitting firmly. Do not apply tape to compression fittings.
7.2
MAN/OFF/AUTO SWITCH
Select the MAN (ON) position on the main switch. Select AUTO if using external controllers or switches. The VFD
will now adjust the speed of the motor / pump so that the system pressure is steady at 1,000 psi / 70 bar. Depending
on the number of nozzles running in the system at any particular time,
7.3
PRESSURE REGULATOR
DO NOT ADJUST THE PRESSURE REGULATOR.
The regulator is installed as a safety valve only
and is factory set at 1200 psi / 84 Bar. Should the regulator be taken apart for any reason, the correct reassembly
sequence is shown below.
NEVER DISSASSEMBLE THE REGULATOR UNDER PRESSURE!
