7.1.5 To start the RHINO module press F1 (run in Manual). The pump module will now run, 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, there is a 3 second delay before the
system goes to “FAULT”. Refer to section 9 to reset.
7.1.6 The pump motor RPM will ramp (increase) up to the maximum speed (50 Hz) to fill the system. Do not worry
if the pressure does NOT reach 1,000 PSI (69 BAR) at this time (during flush sequence).
7.1.7 Let the module run for 2-3 minutes making sure that there is a good flow of water running out the end of the
atomization lines. Lines may have to be flushed in groups with larger system to ensure adequate system
flush.
7.1.8 When finished, press F3 (Stop) to stop the pump module.
7.1.9 The system is now flushed and ready for the pressurization procedure.
8. PRESSURIZING THE SYSTEM
PRESSURIZING THE SYSTEM
8.1.1 Safety glasses must be worn when adjusting pressure. Always keep guards and covers in place.
8.1.2 Install the plugs or automatic drain valves into the ends of the atomization lines. Use Teflon tape on all NPT
threads and tighten each fitting firmly. Do not apply tape to compression fittings or ball seat fittings (Female
swivel hose fitting).
8.1.3 Press F1 to start the pump. The RHINO pump will run at full speed until 1100 PSI (regulator setting) is
achieved. The pump will then slow down and maintain 1000 PSI.
DO NOT ADJUST THE PRESSURE REGULATOR
The regulator is set as a safety valve should the system pressure exceed 1,100 psi or 75.8 Bar. At extremely low
flow, the regulator will bypass water back into the pump head as the VFD drive has reached its minimum Frequency
(Hertz) as mentioned in the above section. NEVER DISASSEMBLE THE REGULATOR UNDER PRESSURE!
If for any reason the regulator is adjusted, or changed, follow this procedure to reset the correct adjustment.
8.2.1 Turn off the electrical supply at the disconnect switch to electrically isolate the pump.
8.2.2 Locate the pressure transducer and unplug the electrical lead.
8.2.3 Restore the power and start the unit by pressing F1.
8.2.4 Adjust the regulator by turning clockwise or counter-clockwise until the pressure gauge indicates
1,100 psi (75.8 Bar). When the pressure is steady at 1,100 make sure that the “Jam Nut” is tightened
to lock the adjustment in position.
8.2.5 Press F3 to turn off the pump, disconnect the electrical supply.
8.2.6 Plug electrical lead back into transducer, restore electrical power.
