Installation Arrangement
Check the direction of ow indicated by an arrow on the
pump casing and install the pump between the isolating
valves. When replacing pump maintain the same direction
of ow.
Ensure no water leakage onto the pump motor or its
electrical connections during installations, venting or
operations as this may cause electrical shocks.
Non-approved replacement parts may not be used.
Any action that doesn’t comply with safety warning sign may
cause personal injury, pump damage and losses in property.
Users must also comply with the local safety regulations.

3.1 Location
The pump can be installed indoors or outdoors but it must not be exposed to
inclement weather. It is recommended that the pump is installed near a drain or in
a drip tray connected to a drain in order to lead away possible condensation from
cold surfaces.
3.2 Minimum Space
The pump requires a minimum space of 620x400x530mm. Even though the
pump does not require much space, it is recommended that there is enough
room for service and maintenance access.
3.3 System Sizing
The pump is factory set with 3bar outlet pressure which can be adjusted
according to demand. The tank pre-charge pressure is 1.25bar.
In case of suction lift of more than 6m, the pump outlet pressure must be at least
2m water column or 0.2bar minimum. Inorder to obtain optimum operation, the
suction lift should be kept as low as possible.

Always loosen and tighten the union nuts on the inlet and
outlet port by hand. Damage to the inlet and outlet ports
increases the risk of leakage.
WARNING
3.4 Piping Connection
Ensure that the pump is not stressed by the piping system.
Flexible hose is strongly recommended.
WARNING
1. Turn the union nuts by hand to loosen the inlet and outlet ports.
2. Seal the pipe fittings using thread tape.
3. Carefully screw the inlet and outlet connections onto the pipe fittings using a pipe
wrench or similar tool. Keep the union nut on the pipe fitting if it has been removed
from the pump.
4. Fasten the connections to the inlet and outlet. Hold the connection with one hand
and tighten the union nut with the other hand.

4. OPERATION
4.1 Priming the pump
Unscrew the priming plug and pour atleast 1.2 litres of water into the pump.
4.2 Starting the pump
1. Open a tap to prepare the pump for venting.
2. Plug pump onto power and the pump will start shortly.
3. Allow water to flow out until it stops bubbling, when all the air is expelled,
close the tap.
4. Open the highest tap in the installation.
5. Adjust the pressure set point to required pressure by adjusting the buttons
on the control panel.
6. Close the tap.
7. The pump is ready for use.
4.3 Setting the correct pressure
The pump can be set between 1.0 to 5.5bar at intervals of 0.5bar. The factory
setting is 3bar.
The default pressure of 3.0 bar will suit most applications. The difference
between the inlet and outlet pressure must not exceed 3.5bar. Example: If the
inlet pressure is 0.5bar, the maximum outlet pressure should be 4bar. If the
pressure is set too high the pump will operate intermittently.
The difference between the inlet and outlet pressure
should not exceed 3.5bar.
