ADDITIONAL COMPONENTS INFORMATION
Heater
The heater is encased in a metal housing with integral safety cut-out and fuse. It connects to the
Circulating Wash pump housing via a bayonet fitting. Refer to the Circulating Wash Pump description.
Thermistor
Situated on the sump. A temperature rise in the water is converted to a changing resistance value.
A rise in temperature will give a lower resistance across the terminals of the thermistor; the control
module monitors this value and when it is the same as that as defined in the programme selected, the
module will advance the programme out of the heating stage.
Regeneration Procedure
Unlike previous models Regeneration is not carried out during every wash. The Control Module counts
the number of Litres used since the last Regeneration.
The volume of water (in Litres) used between Regeneration is dependant upon the Water Hardness
Setting stored in the Control Module. (Refer to "Setting the Water Hardness"). See Chart below.
Regeneration Sequence
1. Regeneration valve activated, after 2 seconds, the fill inlet solenoid is opened to allow water flow,
water flows from the inlet through the salt and the mixture of water and salt reaches the resins.
2.
Solenoid valve closes (the inlet valve and after 2 seconds the regeneration valve).
3.
Pause for 10 minutes.
4.
Fill with 190cc of water (same procedure as step 1.).
5.
5 minutes pause.
6.
Starts resin wash. Between 1 and 2 litres of water flow directly through the resins (Inlet valve is on,
regeneration valve is off.).
7.
Drains
Note:
Regeneration time is hidden within the cycle so does not affect programme times.
Aqua-Stop Inlet Valve
The Aqua stop inlet water valve is located in
the tap end of the fill hose.
In the event of a split fill hose or the machine
leaking, water will fill the base tray and
operate the base float switch, which will
signal the module to switch off the inlet
valve.
