6.1.4. Additional tips

• When the controller is first plugged in, it may display the message "E3", this means that the
controller is rotating to the home position. If the "E2" is displayed, check that the incoming
power frequency matches the controller;
• The preset default time of regeneration is 2:00 AM;
• Power supply: the World controller senses the electrical input and decides which is needed;
• Electrical power is not available, the camshaft can be rotated counter-clockwise by hand if the
motor is removed;
• The controller sends commands to the motor for camshaft movement. However, water
pressure/flow are required during the regeneration cycle for backwash, purge and refill, and
brine draw to actually take place;
• Make sure the control power source is plugged in. The transformer should be connected to a
non-switched power source;
You can start programming from the beginning by resetting the controller, see chapter 

Cleaning, disinfection and sanitization

The construction materials of the modern water softener will not support bacterial growth, nor will
these materials contaminate a water supply. During normal use, a softener may become fouled with
organic matter, or in some cases with bacteria from the water supply. This may result in an off-taste
or odour in the water. In this case, the tank of the softener must be cleaned and disinfected.
Some softeners may need to be disinfected after installation and some softeners will require periodic
disinfection during their normal lifetime.
Depending on the conditions of use, the softener type, the type of ion exchanger, and the disinfectant
available, a choice can be made among the following methods.

6.2.1. Cleaning of softeners

Make sure the brine tanks remains free from debris, waste, scraps that could be drown in the valve
during brine draw cycles of regenerations. Make sure the softener and its parts remains clean to
ensure proper function. Note that camshaft positioning is made by a optical sensor. Should this
optical sensor be obstructed, malfunctions may happen.

6.2.2. Disinfection with sodium or calcium hypochlorite

These materials are satisfactory for use with polystyrene resins, synthetic gel zeolite, greensand and
bentonites.
