ELECTRICAL INSTALLATION
Electrical Installation
The pump unit must be located on a vertical surface with the inlet/outlet connections at the bottom of the unit in
horizontal alignment, with the AKW case logo uppermost.
The unit must be located away from the direct line of water jets whenever possible.
Cable to and from the pump must be run directly out of zone 1 by the shortest route below the unit or directly behind
into the vertical surface. All such routes must be sealed to prevent water ingress.
Cables routed from above, down into the device, act as a drip path and should not be used.
Cables must be protected against mechanical damage and sealed against water ingress.
The case must not be cut except for the thin rear shroud. Do not pierce casing. Use the supplied Pump Spacers kit
to route the cables behind the unit.
The clearance behind the unit and separation from the wall must be minimal and the gap must not be sealed.
All casing cable glands must be visually checked for presence of the elastomeric centre sealing grommet and
tightness checked and confirmed before installing against the wall.
No cable joints may be made in zone 1.
The unit inner cover must not be disturbed and the outer cover must be correctly fitted.

Disconnect pump motor cable.
Remove pump assembly from the back
plate to access the fixing holes.
Fit to a finished surface. Pipe connections
must be easily accessible and a clearance
of 100mm around the base and sides is
recommended. Using the back plate as a
template mark the fixing holes. Drill and
plug the wall taking care there are no hidden
cables or pipes. Use all the screw fixing
positions.
Mount the pump to the finished surface using
all the wall fixings. Use the Pump Spacers to
prevent the cables being trapped. See Fitting

SETTING FLOW DIRECTION
Setting Flow Direction
Fit the non-return valves as shown. Fit the
pump connectors to the pump. Note 15mm
connector (M11) and 22mm connector
(M17 & M20) for the inlet. Screw both
connectors into place. No thread sealant
needed, firmly hand tighten only - do not use
mechanical tighteners as the product is liable
to split.
Check that you have not overtightened
and distorted the non-return valves
before connecting the pipework.
Check that the flow is in the required direction, reverse as required. Loosen the pump head housing,
rotate and fully tighten home. The pipework to this high performance pump must be clamped down
effectively. AKW advise and recommend you clamp pipework either side of joints, junctions or
connections and at a maximum of 500mm between other supports.
Remove shipping tapes from pump inlet
and outlet. Refit the pump to the back
plate. Reconnect pump motor cable.
