3. WEKA Protector

3.1 General

WEKA strongly recommends installing one WEKA Protector per Boxcooler. This will
protect the Boxcooler ( to a certain level) from being damaged by ICCP-systems or stray
currents originating from sacrificial anodes. The WEKA Protector is a small device, which is
placed in the vicinity of the Boxcooler to be protected.

3.2 Installation

One WEKA Protector is normally supplied for each Boxcooler.
The WEKA Protector consists of a small box with two wires, a blue and a red. Each
cable is 300 cm of length. The WEKA Protector needs no additional power supply.
The blue cable is connected to the ship's ground. The red (or brown) cable
is connected to the tube-sheet of the Boxcooler.
In appendix B, a connection diagram is found for the WEKA Protector.
When the WEKA Protector is connected, you must disconnect the WEKA
Guard.

3.3 Placement of the WEKA Protector

The WEKA Protector shall be located near the Boxcoolers in an accessible
position. There are mounting holes around the perimeter of the tube-sheet that
are prepared for screws for attaching the WEKA Protector in a protected and
visible place.
Every two minutes the device will give a flash to show that the protector is working properly.
The WEKA Protector shall be mounted at a sturdy frame, in a dry and well-
protected position, and mounted in such a way that excessive vibrations
are avoided.
NOTE: The WEKA Protector must not be attached to the Boxcooler itself since
the high operating temperature of the Boxcooler may damage the electronics in
the WEKA Protector.
After 5 years the WEKA Protector has to be replaced with a new one.
