4.6 Replacing the Internal Hydrophobic Filter
Warning! A hydrophobic filter must be fitted internally to prevent liquid passing through to
the pump. Hydrophobic filters only work once and should be replaced
immediately it becomes wetted.
When replacing filters, particularly the hydrophobic filter, it is important to ensure the filter is connected
correctly to suit the direction of flow. The filters will only operate efficiently in one direction. The flow
diagram indicates the correct orientation installed in the pipework.

4.7 Replacing the Main Cable
Warning! Always electrically isolate the SA suction unit from the mains power supply
before carrying out any cleaning, maintenance or repairs. Electrical isolation of
the
SA
suction unit is by removal of the mains power cable from the mains
power supply.
• Isolate the SA suction unit from the mains power supply!
•
Detach the back panel to access the internal terminal block.
• Disconnect the brown and blue conductors of the cable from the terminal block, and
withdraw the cable.
•
Fit the replacement cable through the access hole.
• Connect the conductors to their respective terminals (Blue to Blue and Brown to Brown) in
the terminal block. Provide sufficient length of cable between the gland and terminal
block.
•
Fit the cable into the labyrinth.
• Ensure all conductors are fitted as the original.
• Check continuity of each circuit.
•
If reconnection is correct - replace the back panel.
