8.2.1.1 Changing mains fuse
• Turn off mains power to the control.
• The mains fuse is located in a fuse holder in the terminal box of the control; fuse can be
reached by opening the control and lifting up the upper portion (see ch. 8.2.1).
• After releasing the bayonet catch of the fuse holder, take out the defective fuse and replace
with new one.
• Fasten bayonet catch again and close housing.
For specifications of required fuses, see ch. 1.2.7.1.
8.2.1.2 Installation of cable connections
Sealed holes are provided on the underside of the control to be broken out for the electrical
installation (see fig. 4, ch. 1.2.7.1).
• Break out passages for mains power and level monitoring devices, and further passages
according to configuration of the system (see fig. 21 below).
• Attach the cables in the back row first for reasons of space.
• A screwdriver or drift with a maximum diameter of 3.5 mm is required for breaking out
the holes in the back row (Pg 9 and Pg 11). Use the tools recommended to avoid damage to
the PC- board and threadings.
• For the leakage warning (double passage), slide the screw fitting (if necessary with O-ring)
onto the cable, place in the Pg 9 threaded hole and tighten; be careful not to squeeze the
O-ring out by tightening too much.
• The nine passages in the front row are for Pg 7 screw fittings. For best results, use water
pump pliers to break out the holes, and place a flat brace (e.g. a coin) under the hole to
protect the outer edges and especially the raised faces of the threadings.
• When using a Pg 7 screw fitting, slide (do not twist or stuff) cable through opening carefully.
• Secure Pg 7 screw fittings with a lock nut (SW 15).
• Trim flex to the exact length, remove approx. 7 mm insulation and run these to the terminals
according to the wiring diagram; use end sleeves.
• In order to distinguish between two identical cables (e.g. power supply), each cable is fitted
with a different identification ring (“S” for acid German “Säure”, “C” for chlorite and “W” for
water).
8.2.2 Connections at distributor box
• Setting the distribution voltage for the metering pumps and the control is carried out at the
factory.
• Wiring the bypass pump to the distributor box and from there on to the control is carried out
by the customer on location.
• Attach the mains power connection (T1 brown, T2 blue and yellow/green) to the shut-off
switch and to the ground terminal.
For pin configuration, see fig 5, ch. 1.2.7.2.
8.3 Dismantling the chlorine dioxide system
First shut down the chlorine dioxide system (see Ch. 3 “Shutting down chlorine dioxide system”).
See section D for general safety information.
Close the stop valves located in the bypass.
Flush the system thoroughly with water and empty.
8.4 Disposal of used parts
Plastic material is hazardous waste and must be recycled. For this reason it is necessary when
returning the system to clean it thoroughly of chemicals. Used parts will normally be accepted
at collection sites of cities and communities or at any ProMinent outlet.
