13.3 520REC: fitting the drain port

The drain port is an optional extra, supplied with the pumphead. It is strongly
recommended that users fit it before the pump is operated. This may be done with the rotor
in position or removed.
Remove the drain plug from the bottom of the pumphead. The drain plug is flexible. It

may be removed using finger pressure from within the pumphead, or by accessing its
flange from outside with a fingernail.
 Drop the port into position from inside the pumphead.
Fit the supplied port retaining nut (3/8in BSP) and finger-tighten.

Fit drainage pipework as required (not supplied).
