If in doubt, then contact BWT for support. Never attempt to assemble or connect if there is any doubt as to how to do it, or if faults and defects are present in the BWT Desinfecton and its associated equipment.
6.3 Installation The BWT Desinfecton should be installed in a frost-free and well-ventilated room. The BWT Desinfecton should be mounted on an appropriate wall, which can carry the full load of the BWT Desinfecton according to the technical specifications. It is recommended to mount the BWT Desinfecton with 6-8 mm screws, with hexagon heads. The backside of the cabinet is mounted onto two brackets, one in each top-corner.
6.3.2 Installation Procedure NOTICE • Mount the BWT Desinfecton in such a way, that it allows the operator easy access, during both operation of the HMI controller and maintenance inside the cabinet. • The BWT Desinfecton should be mounted so the PLC is within eye level of operator and should always be mounted above the external tanks.
If there is no clear wall-space at the installation site, then a mounting rack can be constructed for the BWT Desinfecton. Specifications for an acceptable mounting rack is provided in Figure 43. All measurements are provided in millimeters.
Figure 44 - Water pump as delivered from factory Figure 45 - Pump cover When the BWT Desinfecton is delivered from the factory, the water pump will have its cover removed and the internal hose detached. Before connecting the generator to water or electrical supply, the hose and the included pump cover must be reinstalled.
When producing Neuthox ® at low pH, the BWT Desinfecton forms chlorine gas. A ventilation pipe must be installed from the buffer tank and the buffer tank must not be sealed. BWT support will be able to advise on this. •...
If this is not adhered to, then the softener and cell can be damaged due to lime scale build-up. • A water softener must be connected to the BWT Desinfecton. This can be purchased at BWT or by another manufacturer. •...

Figure 49 - Connection point for water supply The soft water tank is placed inside the cabinet on the BWT Desinfecton. The tank is connected to the brine tank. The level sensor in the tank is connected to the plug NI01 on the PCB and the leak sensor is connected to the plug NI03 on the PCB.
WARNING The supply voltage must correspond with the values specified for the BWT Desinfecton. The BWT Desinfecton is supplied with 230 VAC (±10%); 50 Hz via a C14-IEC connector, for easy connection to the power supply (Figure 50). Connect the BWT Desinfecton to the electrical power supply and ensure the BWT Desinfecton is connected to a grounded outlet.

Operating Instructions 6.4.5 Dosing Pump Installation on BWT Desinfecton The BWT Desinfecton has no internal dosing pump, but an external dosing pump can be mounted on the right side of the cabinet. The BWT Desinfecton can supply power for an external dosing pump, by connecting it directly to the terminals inside the cabinet (Figure 52).
Page 48
The 2 or 3-lead cable from the water meter is connected directly to the terminals inside the cabinet. If the water meter uses a transistor output be aware of polarity (Figure 52). The water meter is connected to the relay coil and 24 VDC from the BWT Desinfecton. The BWT Desinfecton is connected to a relay contact.

Figure 55 - Injection valve installation 6.4.6.2 ORP Sensor The ORP-sensor must be calibrated by start-up, and the calibration can be done in the BWT. When the ORP-sensor is calibrated, then it can be installed in the water pipe. The ORP-sensor must be installed vertically or at most 45° from vertical with the ORP sensor wire facing upward (Figure 56).
6.4.6.3 ORP-transmitter The process ORP-value is supplied to the BWT Desinfecton as an analogue 4-20 mA signal, from the supplied transmitter. The cable from the transmitter is connected directly to the terminals inside the cabinet.

It is important to make reservations for visitors and other people who are not used to moving about in the area around the BWT Desinfecton and are therefore not aware of the general safety measures or the signage of the BWT Desinfecton.
• The content of FAC in the supply water for the BWT Desinfecton must never exceed 0,2 ppm, as this will damage the softener. FAC chock dosing in supply water at max. 2 ppm, should not be done more than twice a year.
Neuthox tank. 8.3 Consumables 8.3.1 Salt The electrolysis process requires salt. If there is no salt left in the brine tank, the BWT Desinfecton will set off an alarm. ® To ensure a uniform production of Neuthox and to avoid setting off the alarm, salt must be refilled at regular intervals.
8.4 Machine and Work Area - Order and Cleaning To ensure the correct functions and usage of the BWT Desinfecton, the BWT Desinfecton and work area around it must be kept clean and orderly regularly.
When this happens then the soft water cartridge should be flushed, before starting up the BWT Desinfecton. For flushing, see the manual for the soft water cartridge.
