Page 19: Components
COMPONENTS Actuator The thermo hydraulic system consists of a metal cylinder with plunger. The cylinder is filled with a substance which expands greatly when heated. The heat source is a PTC (positive temperature coefficient) which is in direct contact with the metal cylinder. A strong pressure spring returns the plunger back to its original position when the heat source is switched off. -
Page 20: Aqua Sensor (Optional)
Aqua sensor (optional) The infrared light-emitting diode and the photodiode are located opposite each other in a U-shaped translucent housing on a board. The infrared diode transmits infrared light through the water flowing between the U to the light-sensitive base of the photodiode which then becomes conductive. -
Page 21: Aqua Stop Valve
Aqua Stop valve The valve system consists of two valves in series, which are actuated electrically parallel, and the filler valve and safety valve. The safety function may be actuated via the safety level chamber or electrically via the float in the base pan. The water flow is then stopped mechanically. - Page 22 Removal Open the housing; disconnect the inlet hose; sever the electrical connection cables; strip the insulation from the ends of the wires; push the shrink-fit hose over the cable; connect the wires to the insulating sleeves (1). After fitting, warm the connectors until the shrinkage process occurs and the hot-melt adhesive comes out of the ends of the connectors (2).

Page 36: Spray System
4.18 Spray system The rotor spray system consists of three spraying levels, the lower and upper spray arms and a roof shower head. Water is supplied to the upper spray arm and the roof shower head via the supply pipe attached to the inside of the tank rear panel. -
Page 37: Water Inlet Without Heat Exchanger
4.19 Water inlet without heat exchanger When the filler valve has been opened, the water flows towards the integrated inlet via a free flow channel and into the regeneration chamber. When the regeneration chamber has been filled, the water flows through the water softening system via the overflow channel and then flows as soft water into the level sensor and pump sump. - Page 38 4.19.1 Filling procedure for appliances without a heat exchanger When the static level has been reached, the module is actuated by the level switch, moves to the next position and the circulation pump is switched on. When the circulation pump starts up, the level pressure switch switches back.
