Module: cover removal and refitting
The pump can be connected with other devices by means of the terminal connectors within
the relay module situated on the side of the pump. The relay module cover must be
removed from the pump housing to allow suitable cables to be connected to the terminal
connectors via the watertight cable glands on the module.
Removing the relay module cover.
The module cover is secured to the side of the drive unit by four M3x10 Pozidriv pan head
stainless steel screws.
Remove the four screws from the module cover, leaving the
top left screw until last. It is possible that the sealing strip
may cause the module to adhere to the drive housing. If so a
gentle tap will free it.
Do not
use a tool to force it off.
The sealing strip should be retained within its channel on the
side panel of the drive housing. It ensures ingress protection
between the drive housing and the module cover. Check the
integrity of the sealing strip. If it is damaged it must be
replaced.
Refitting the relay module cover.
Ensure the sealing strip is undamaged and positioned within
its channel on the side of the drive housing. Hold the module
cover in place, taking care not to disturb the sealing strip.
Starting with the top left screw, tighten the four retaining
screws to 2.5 Nm.
