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.
