1.0 GENERAL
THESE INSTRUCTIONS ARE FOR USE WITH PART NUMBER LV310545 ONLY.
The Correx®power anode protection system is designed to protect the inner surface of the CAVALIER
range of Electric storage water heaters. The Correx®system replaces the standard magnesium
sacrificial anodes.
Due to the fact the Correx® Ti-Anodes are non-sacrificial, maintenance costs are reduced. Anode
inspection/replacement is no longer required. The only check required is to ensure a green LED is
illuminated on the Correx®front cover.
2.0 OPERATION
The Correx® system operates on a 230V 1ph 50Hz electrical supply and has a 10V output to a titanium
anode (Ti-Anode). A small current is passed from the potentiostat and emitted from the Ti-Anode to the
inner surface of the storage vessel, neutralising the naturally occurring electrolytic action of the stored
water.

NOTE - An impact wrench may be required to remove the magnesium anodes –if using such a
tool the appropriate PPE must be worn.
Isolate the unit 230v at the local isolator.
Let the vessel cool down before draining and removing the anode. Hot water
can cause severe burns.
Drain the storage vessel before attempting to remove the anode.

4.2 INSTALLING THE Ti-ANODE
Refer to photographs found on pages 6 and 7 for additional guidance.
1. Layout components found in the Correx® box ensure all components are present
before starting installation.
2. Remove plastic cap surrounding anode (Left hand side)
3. Remove the sacrificial magnesium anode (27mm)
4. Fit the Ti-Anode (item No.2) Sealant should be applied.
5. Torque anode to 28 Nm
DO NOT tighten over 28Nm otherwise the Correx may not operate correctly
4.3 INSTALLING THE CORREX®POWER ANODE BOX
1. Mount the Correx®Power Anode Box (Item No.1) to the left hand side of the Water
heater door.
2. Mark and drill hole in order to mount the control box (Photo 3)
3. Using the screws provided (Item No.3) secure the Correx®Power Anode Box to the
unit.
4. Refit the plastic cap surrounding the anode and connect the Ti-anode spade
connection onto the Ti-anode.
5. Mark and drill hole for earth wire on the top of the tank (Photo 5)
6. Using the last remaining screw fix the earth wire to the top of the tank.
7. Tidy up any loose wiring, this can be placed behind the Correx®Power Anode Box
8. Remove the front cover from the Correx®power anode Box (Item No.1).
9. Conduct a continuity check from the potentiostat to the Ti-anode and from the
Potentiostat to the cathode bonding strap and tank body to ensure sound connections.
You may need to remove the spade connectors on the potentiostat to do this.
10. Replace front cover.
