Electrical Installation
Ensure Mains Power Supply is Switched OFF before starting wiring.
DO NOT take risks with Plumbing or Electrical Installation.
Only a competent trades person should attempt this installation.
This product is rated at IP45 and may be installed in Zone 1, 2 and 3 of a shower room only if the following
conditions are fully complied with.
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.
The 230V AC power supply to this unit must be provided via a two-pole isolator switch and a dedicated
circuit with a 30mA RCD device installed in accordance with the latest revision of the Wiring Regulations BS7671.
It must be wired into a fused, unswitched, fixed wiring connector fitted with a 5 amp fuse.
The IP45 rating of the AKW pump product refers to the inner casing containing the electrical control gear.
The pump motor which operates at SELV 32 DC (maximum) is located within the outer cover.
