Page 70: Circulation Pump (Sicasym)
Service Manual 6.18 Circulation pump (SICASYM) The circulation pump is operated by means of a single-phase alternating current motor. Switching the two motor windings with the motor capacitor is either activated by an electronic unit or a relay on the motor connection or by the module. During the start-up phase the two windings (in series with the capacitor) are parallel to one another direct on the power supply and generate an extremely powerful starting force. - Page 71 Service Manual 6.18.2 Assembly INFO! Leakages Ensure that all 4 locking hooks in the pump housing are attached. Sluggish or blocked fan impeller When the pump is changed, the spacer ring attached to the motor shaft must be trans- ferred to the new pump. Rotate pump to the left into the pump housing until the catch engages.

Page 77: Fill System
Service Manual Fill system Intake of water with heat exchanger After the fill solenoid is opened, the water flows to the integrated inlet over the free flow line into the re- generation chamber. When the regeneration chamber has been filled the water will flow through the overflow channel in the softening equipment and as soft water into the level sensor and the pump cavity. -
Page 78: Regeneration With Heat Exchanger
Service Manual 7.1.1 Filling procedure for appliances without a heat exchanger After the static level has been reached the module will be selected by the level switch, will move into the next position and the circulation pump will be switched on again. The level pressure switch is reset when the circulation pump commences operation. - Page 79 Service Manual Regeneration and rinsing through the water softener is carried out in the washing cycle. During regen- eration the regenerating valve on the softener is opened. The reservoired quantity of water flows across the valve into the salt container, is enriched with salt, and flows as brine through the softener into the heat exchanger.
- Page 80 Service Manual 7.2.1 Filling procedure for appliances with a heat exchanger The electronic determines the time between the open command of the fill solenoid and the closing of the level switch (f1). From this time the additional fill time of the fill solenoid is calculated. For every initial fill- up in a rinsing program, 200 ml more water than the standard water volume will be filled in.
