When the procedure is complete, first unplug the WATA-Standard’s power
supply and then turn off the generator.
W Respect the 10-hour maximum period of use
To avoid the risk of overheating the power supply, do not use the
WATA-Standard for more than 10 consecutive hours. Successive productions
of 2 L are recommended.
W Overheating of the power supply
If overheating occurs, power will automatically shut off and then restart when
its internal temperature falls below 70°C. However, it is advisable to stop the
procedure and allow the power supply to cool down for 15 minutes.
W Respect the 6 g/L concentration
The WATA-Standard is designed to produce a sodium hypochlorite solution
with a 0.1 to 0.6% concentration of active chlorine. The concentration must
not exceed 0.7%. Prolonged use or excessive salt will result in raising the
temperature of the bath, not in increasing the concentration. If this occurs,
there is a risk of damaging the power supply and/or not achieving the 0.6%
concentration. Use WataTest to measure concentration once the procedure
is complete.
W Water temperature should be less than 42°C
In order to avoid the formation of undesirable by-products, the temperature
of the water should be checked regularly during production, using a clean
thermometer. The temperature should be less than 42°C. To begin the
procedure, use water with a temperature between 20 and 27°C.
W Use a log book
To facilitate the monitoring of chlorine production and to trace the origin
of problems that might arise, use a log book to record, each time the
WATA-Standard is used, the name of the person responsible for production,
the starting and finishing times of production and a short description of the
procedure. You’ll find examples in the “tool kit” on our website, www.antenna.ch.
W Regularly check production
Production should be checked at least every two hours or more frequently.
Watch for bubbles in the solution; this is proof that electrolysis is working
properly. Make sure that the power supply does not overheat. If there is a
possibility that dust or elements could fall into the solution, cover it with a
mosquito net type lid. This will allow the gas to escape and, if the area is well
ventilated, to dissipate.
