VARIABLE SPEED PUMP SYSTEM INTRODUCTION
THEORY OF OPERATION
The variable speed pump controls out going variable pressures of the water for
better equipment operation by maintaining a constant pressure on the system.
The pump is capable of producing 26 GPM or more at a minimum of 30 PSI.
The variable speed pump system is controlled by a VFD controller mounted to
the motor. The unit is set to stop at the set pressure if there is no flow. The
electronics will look at the pressure but will not try to start the motor until it sees
pressure drop.
INSTALLATION
The following guidelines should be met at installation.
1. Mount the variable speed booster pump system on a firm level foundation
by using bolts through the .50 dia. pre drilled holes in the unistrut channel.
2. To insure sufficient cooling of motor and electronics, the following must be
observed:
Place the pump in such a way that sufficient cooling is ensured.
The temperature of the cooling air must not exceed 40 degrees C.
Cooling fins and fan blades must be kept clean.
3. The size of the inlet water supply piping should be 1”.
4. The size of the outlet piping from the variable speed pump system should
be 1”.
5. Follow all local plumbing and electrical codes. The pump is 220-230 volt
single-phase.
Warning: All electric supply circuits must be interrupted before
working in the pump terminal box. Never make any
connections in the pump terminal box unless the
electricity supply has been switched off for at least
5 minutes.
6. A blade or service disconnect isn’t provided. It must be installed. The
pump must be connected to an external all-pole mains switch with a
contact separation of at least 3 mm in each pole according to IEC 364.
Warning: The pump must be earthed and protected against indirect
contact in accordance with national regulations.

2
Protective earth conductors must always have a .
yellow/green (PE) or yellow/green/blue (PEN) color
marking.
7. If the pump is connected to an electric installation where an earth leakage
circuit breaker is used as additional protection, this circuit must be marked
with the following symbol:
When an earth leakage circuit breaker is selected, the total leakage
current of all the electrical equipment in the installation must be taken into
account.
Earth leakage current < 3.5 mA.
The leakage currents are measured in accordance with EN 60 355-1
8. The motor requires no external motor protection. The pump is
overvoltage-protected.
9. Supply voltage:
1 x 208-230V Single Phase.
Cable: 0.5 – 1.5mm2 / 14-12 AWG.
See nameplate.
Recommended fuse size:
Motor sizes from 0.37 to 1.1 kW: Max. 10 A.
Standard as well as quick-blow or slow-blow fuses may be used
Warning: If the supply cable is damaged, it
must be replaced by the
manufacturer, the manufacturer’s
service partner or similarly qualified
persons in order to avoid a hazard.
10. The number of starts and stops by way of the
mains voltage must not
exceed 4 times per hour.

3
When the pump is switched on by way of the mains, it will start after
approx. 5 seconds.
When the pump is started/stopped by way of an external on/off switch, it
will start immediately.
Note: These steps have been already completed at assembly for
this product. For your information:
The connection terminals inside the pump terminal box for
the pressure sensor and blade or service disconnect cord
are shown in the figure below with installation directions
listed.
Warning: Never make any connections in the pump terminal box
unless the electricity supply has been switched off for at
least 5 minutes.
Pressure Sensor Installation: With the protective cover off, bring the wire
from the pressure sensor into the motor through the strain relief in the middle.
Connect the yellow-green wire to terminal 6, the blue wire to terminal 7 and the
brown wire to terminal 8. Clip the remaining wires as they are not used. Make
sure remaining wires are isolated from ground. Replace the access cover after
all connections have been made.
Blade or Service Disconnect Cord Installation: With the protective cover off,
bring the line cord through the strain relief furthest from the pump inlet.
Terminate the white wire into the connection marked N, the green wire to
ground terminal and the black wire to L. Replace the grey protective cover after
all connections have been made.

START-UP
Warning: At high temperatures, the pump may be extremely hot. Do not
touch it.
Priming:
Before startup, or if the pump has been drained, the pump must be filled with
liquid and vented.
Proceed as follows:
Close the discharge isolating valve and bypass valve.
(See System Design drawing)
Remove the priming plug in the pump sleeve. (See Plug drawing).
Slowly open the suction valve (See System Design drawing), in the inlet
pipe until a steady stream of liquid runs out of the priming port.
Warning: The escaping liquid may be very hot. Therefore, care must be
taken to ensure that the liquid does not cause personal injury or
damage to other components.
Replace priming plug and tighten securely.
Start the pump and slowly open the discharge valve until it is fully open.
Completely open the suction valve in the inlet pipe.

MAINTENANCE
The pump and motor are maintenance free.
PRELIMINARY CHECKS: MEASURING VOLTAGE & CURRENT
When measuring voltage, use a volt meter,(set to the proper scale) to measure
the voltage at the pump terminal box or starter.
Measure between power leads L1 and L2 or L1 and N for 115 volt units.
When the motor is under load, the voltage should be within +6% to +10% of the
Nameplate voltage. Larger voltage variation may cause winding damage.
Large variations in the voltage indicate a poor electrical supply and the pump
should not be operated until these variations have been corrected. If the voltage
constantly remains high or low, the motor should be changed.
When measuring current, use an ammeter (set on the proper scale) to measure
the current on each power lead at the terminal box or starter. See the motor
nameplate for amp draw information.
Current should be measured when the pump is operating at a constant discharge
pressure.
TROUBLE SHOOTING THE PUMP
Before removing the terminal box cover, make sure that the electricity supply has
been switched off.
Warning: The pumped liquid may be scalding hot and under high pressure.
Before any removal or dismantling of the pump, the system must
be drained or the suction & discharge valves must be closed.
Fault Cause ___________________
Pump capacity not constant. a) Pump inlet pressure is too low.
b) Inlet pipe partly blocked by
impurities
c) Pump takes in air.
___________________________________________________________
Pump runs but gives no water. a) Inlet pipe partly blocked by
impurities
b) Suction valve blocked in closed
position.
c) Leakage in inlet pipe.
d) Air in inlet pipe or pump.
___________________________________________________________
Pump runs backwards when a) Leakage in inlet pipe.
switched off. b) Suction valve defective.
c) Suction valve blocked in open
or partly open position.
___________________________________________________________
Valves
Do not run the pump without the suction or discharge valve completely open
during normal operation. The bypass valve should be closed at this time.

SETTING BY MEANS OF CONTROL PANEL
Warning: The motor can develop surface temperatures up to 115 degrees F.
Touching the motor for any length of time may cause burns. Only
the buttons should be touched to avoid injury.
The pump control panel, incorporates the following
buttons and indicator lights:
CONTROL PANEL
The desired setpoint is set by pressing the up or down button.
The light fields on the control panel will indicate the setpoint set.

SETPOINT SETTING
PUMP IN CONTROLLED-OPERATION MODE
The figure below represents the pump in controlled-operation mode
(pressure control).
The light fields 5 and 6 are activated, indicating a desired setpoint
of 3 bar. The setting range is equal to the sensor measuring range
(see sensor nameplate).
Setpoint set to 3 bar, pressure-control mode
The buttons on the pump control panel will toggle the pressure up or down
at 14.5 PSI increments. The gauge positioned by the sensor on the
variable speed unit, shows the discharge pressure of the pump.

10
FAULT INDICATION
A fault indication can be reset in one of the following ways:
By briefly pressing the up or down button on the pump. This will not
change the setting of the pump.
A fault indication cannot be reset by means of the up or down button
if the buttons have been locked.
By switching off the electricity supply until the indicator lights are off.
