3. INSTALLATION OF THE PUMP MODULE
Installation Procedure:
•
Determine pump module location
•
Identify water supply/connection for the system
• Determine routing of the high pressure manifold from the pump.
•
Establish drainage location from the pump.
•
Verify correct electrical power supply to the pump.
• Determine all of the above for optional Equipment - Zone Controllers, Temperature/Humidity Controllers, Reverse
Osmosis, UV sterilizers, etc...
POSITIONING THE PUMP MODULE
The pump module requires a flat level surface. Position selection will largely depend on the availability of power and
water, but remember the points outlined on the previous pages as the terms of the pump warranty depend upon it.
A concrete floor or a concrete slab is ideal. Attach the supplied adjustable feet and plugs to the legs of the pump as
shown in the photograph (right). Using a level, make sure that the RHINO unit sits as level and plumb as possible.
WATER SUPPLY AND CONNECTION
The water supply should be capable of 1.5 times the maximum flow of the pump as shown in the table below.
Pump Model & Flow MIN Flow rate
(USGPM)
MIN Flow Rate (LPM) MIN Pressure psi /
bars
RHINO 15 (56.8L) 22.5 85 20 / 1.40
RHINO 20 (75.8L) 30.0 114 20 / 1.40
RHINO 25 (94.6L) 37.5 142 20 / 1.40
Correct water pressure and flow rate are essential to pump operation. All pump modules require a minimum of 20
P.S.I. (1.40 BAR) and a maximum of 90 P.S.I. (6.20 BAR) while in operation. The pressure should always be constant
and not fluctuate outside these ranges, especially on system start up. All pump modules are equipped with an inlet
water fault delay timer, which allows small drops in pressure, but will ultimately “fault off” if low pressure is present
for more than a few seconds.
Ensure that either copper or PVC pipe is used to provide the correct water supply to the RHINO unit. Never use steel
or galvanized steel fittings. Always use the largest diameter pipe practical.
DRAINAGE FROM THE PUMP
After the pump module shuts down, the water remaining in the manifold lines will drain out through the pump module
and the end of the atomization lines on some lines. Ensure that the drain outlet is routed to a suitable drainage point
to avoid flooding. A 6 foot (1.8 M) low pressure drain hose is provided for this purpose. This hose can be extended
as necessary.

PUMP MODULE POWER SUPPLY
After all water and plumbing connections have been completed, a licensed, qualified electrician should connect the power
supply to the pump. It is important to follow the National Electrical Code (NEC), as well as any local codes to ensure a
safe installation.
CAUTION !
If the pump unit will be powerd by a generator at any time, a properly sized line reactor needs to be
installed prior to the pump unit to eliminate voltage spikes. If this is not done the Variable Frequency Drive
(VFD) & processor could be damaged and warranty may be void.
