VARIPUMP 10,000 TO 1½” PRESSURE PIPE
We recommend connecting Varipump 10,000 to 1½” Pressure Pipe.
To do this we recommend screwing a 1½” Single Union, Threaded Female To Plain Female
(EA Code: K82-76-55) onto the inlet and outlet of the Varipump. This also enables easy
access to the pump for maintenance when on a gravity fed set-up.
You can then glue 1½” Pressure Pipe (U15-050) directly into these connectors,
using Solvent Weld Adhesive (EA Code: S79-0-500).
VARIPUMP 20,000 AND 30,000 MODELS TO 2” PRESSURE PIPE
We recommend connecting Varipump 20,000 and 30,000 pumps to 2” Pressure Pipe.
To do this we recommend screwing a 2” Single Union, Threaded Female To Plain Female
(EA Code: K82-76-66) onto the inlet and outlet of the Varipump. This also enables easy
access to the pump for maintenance when on a gravity fed set-up.
You can then glue 2” Pressure Pipe (U15-063) directly into these connectors,
using Solvent Weld Adhesive (EA Code: S79-0-500).
If you want to connect the Varipump 20,000 or 30,000 to 1½” Pressure Pipe, follow steps

Gravity fed filter installation example shown
INSTALLATION ADVICE - GRAVITY FED SET-UP
1. The pump suction line should be not smaller than 1½” (40mm imperial)
or 50mm true metric.
2. We recommend using Single Unions, Threaded Female To Plain Female,
to connect to Pressure Pipe (see page 8 for advice).
3. The suction line is to have as few bends or elbows as possible. There must not
be an air trap on the suction line.
4. Tighten the pump fittings only as much as is required to ensure a tight connection.
Excessive torque is unnecessary and may cause damage to the pump.
5. All wiring (electrical) work must be carried out by a qualified electrician and must
be installed in accordance to the local codes.
6. The motor must be earthed.
7. The weight of the plumbing and fittings is to be independently supported and not
carried by the pump.
8. The pump is not self-priming. Therefore, if the water level is below the pump,
a non-return valve must be installed below water level. The pump and inlet line
must be primed prior to start up. For non-flooded installations a check valve
(non-return valve) is recommended.
9. The controller must not be submerged in water.
10. Do not operate the pump without water.

INSTALLATION ADVICE - PUMP FED SET-UP
Varipump can be submersed in water, as part of a pump fed system. When installing
on pump fed systems we recommend using the hosetails provided to connect up to
flexible hose (not supplied).
1. Flexible hose (not supplied) should be the widest possible diameter.
2. Extra steps on hosetails should always be sawn off and removed.
3. A hoseclip (not supplied) must always be used to hold the hose in place on
the hosetail.
4. Ensure sealing rings are fitted properly.
5. If using pressure pipe, use the appropriate Single Unions, Threaded Female To
Plain Female as shown on page 8.
6. All wiring (electrical) work must be carried out by qualified electricians and must be
installed in accordance to the local codes.
7. The motor must be earthed.
8. The controller must not be submerged in water.
9. Do not operate the pump without water.

12
Before installing the Varipump, it is important to consider its location in relation to the mains
power supply and control box. There is 10 metres of cable from the control box to the pump,
and there is 2 metres of cable to connect the control box to the mains supply.
The control box is rated IPX4, therefore it is weather / rain-proof and can be kept outside,
but it MUST NOT be submerged in water.
We recommend securing the control box to a wall in a location you can easily access at all
times. Use the four slots around the edge of the control box to help mount the box, using
appropriately sized screws and wall fixing plugs.
In the unlikely event the pump is supplied with a plug, this can be cut off and removed, as
the mains supply cable should be wired into a safe, compliant, outdoor electrical system,
with an RCD cut-off. Cutting the plug off will not invalidate the warranty.
The cable from the pump has a weatherproof 4 pin connector that should be inserted into
the control box connector. Then slide the sleeve over the connectors and tighten up.

OPERATING THE VARIPUMP
GENERAL OPERATING ADVICE
Once connected, use the button to turn the Varipump on or off. The display shows the
operating wattage that the Varipump is running at. When you press the or buttons to
increase or decrease the flow rate, a number between 0 and 100 appears on the screen.
This indicates the percentage of power that the pump is running at. ZERO means no flow
and 100 means maximum flow (100%). After a few seconds the display reverts back to
display the current wattage.
It may be possible that the operating wattage displayed fluctuates at different times of
the day, this is perfectly normal.
If the display shows letters and numbers, this is a fault code, see TROUBLESHOOTING.
Do not operate the Varipump without water.
Do not use when temperatures are less then 0°C and 35°C. If there is a chance that the
water will freeze over and restrict the flow, then you should take it out of the pond and
dry it out. Store it over Winter in a dry place, then reconnect the pump again in Spring.
The Varipump is not self-priming, therefore, if the water level is below the pump,
a non-return valve must be installed below the water level. The pump and inlet line
must be primed prior to start up. For non-flooded installations a check valve (non-return
valve) is recommended.
Percentage of power displays briefly when
pressing or
Wattage displays when Varipump is on.
Press power button to Varipump off.

once or twice per year. Scan the QR code to watch a cleaning video.
Always turn off the power before removing the pump.
On gravity fed installs, unscrew the collar on the unions to remove the
inlet and outlet pipework.
On pump fed installs, use the handle to pull the pump out of the pond,
do not pull on the cable.
Step 1: Disconnect the pump from the
pipework or flexi-hose connections.
Step 2: Remove the pump strainer basket
(if applicable).
Step 3: Remove the plate from underneath

Step 4: Unscrew all four screws around
the blue plastic impeller housing.
Step 5: Unscrew the screw that is
attached to the handle.
Step 6: Remove the handle.

15
CLEANING THE VARIPUMP
Step 9: Wipe clean to remove any excess
dirt.
Step 10: Re-fit the impeller housing.
This can be positioned at multiple angles.
Step 11: Re-fit the handle and tighten up
the screw.
Step 12: Re-fit all four screws around the
impeller housing and tighten up.
Step 13: Re-fit the base plate. Step 14: Clip on the strainer basket
(if applicable).
Step 7: Carefully pull away the impeller
housing.
Step 8: Use a brush to clean inside and
around the impeller.
