1. PUMP INSTALLATION
Install the pump on a level, vibration free surface.
Use short, direct suction pipe to reduce friction losses. Don't install the pump at more than 3
meters of geometrical height from water level.
Leave enough space for gate valves in suction and discharge piping, if required.
Make sure that floor drainage is adequate to prevent flooding.
Protect the pump from excessive moisture.
Make sure that pump and piping is accessible for servicing.
Note: The pump suction and discharge connections are moulded in thread stops, DO NOT
try to screw the pipe beyond these stops.
1.1 START
The wide range of pump settings makes it suitable for multiple purposes. The pump controller
is used to program motor speeds and schedules as described in Chapter "Schedules" of this
manual.
WARNING:
NEVER run the pump dry! Running the pump dry will damage seals, causing leakage and
flooding. Fill the pump with water before starting.
Always STOP PUMP before and RELEASE ALL PRESSURE from pump and piping system
before servicing.
NEVER tighten or loosen screws while the pump is operating.
Do not block the pump suction.
1.2 PRIMING PUMP
Release all air from filter and piping system (consult your filter user manual).
In a flooded suction system (water source higher than pump), the pump will prime itself
when suction and discharge valves are opened.
If pump is not installed in a flooded suction system, unscrew and remove pump lid and fill
it with water.
WARNING: Tighten / untighten the pump lid by hand only.
1.3 MAIN POWER WIRING
This is an alternative wire connection for those owners who would like
to wire the pump directly to the main power. EPV Pump is supplied with
a power cord that can be plugged into the power source. There are
two terminals labelled as AC-L and AC-N. Attach the power leads to
these terminals. Either wire may be attached to either terminal (see
Figure 1).

Procedure:
Make sure that the pump is disconnected from power
source.
Unscrew the control panel located on the top of the
electric motor. The power connection is located at the
corner where the wire comes out of the box.
As shows Figure 2, unscrew the pin that fastened the
power cord.
Take out the power cord with plug and replace with the
new one.
To fasten the power cord, connect the live wire to the AC-
L pin and the neutral wire to the AC-N pin. The ground wire should connect to the ground
wire pin.
Connect power to ensure the connections are correct. If not, repeat the steps above and
check both pin connections.
Recover the control panel and fasten the screw to prevent potential leakage into the control
panel.

Press “Enter” to save settings or press “ESC” to cancel.
Make sure the pump is in off position before modifying the settings.
2.5.3. SCHEDULE SET UP
The pump is supplied with the pre-set schedules for an easier start-up. If necessary, these
parameters could be changed (see chapter "2.6.4 Programming Flow Chart" for further
details). To modify the schedules, use the following menu parameters (the same method of
programming applies to 4 schedules):
“Function”: Enable / Disable the schedule
“Time on”: Set the start time
“Time off”: Set the off time
“Speed”: Set the speed (RPM)
Make sure the pump is in off position before modifying the settings.
2.5.4. SCHEDULE 1 SET UP
To revise / update "Function" settings:
Press “Menu” to highlight the settings.
Use “Up” / “Down” buttons to go to “Schedules” and press “Enter”.
