4.13 Rinsing and pumping system
The circulation (D) and drainage pumps (H) as well as the instan-
taneous water heater (C) are connected to the pump sump (G) via
plug-and-socket connections. The instantaneous water heater (C) is
also screwed securely to the pump sump. The filter system consists of
three-fold filtration (coarse filter, surface fine filter, microfine filter). The
surface fine filter is attached with the combined coarse and fine filter
cylinders to the base of the pump sump via a bayonet catch. The
detergent solution is drawn into the pump sump by the circulation
pump (D) and forced into the instantaneous water heater (C).
At the appropriate pressure the pressure switch for the heater is ac-
tuated via the flange-mounted membrane. A temperature controller (B)
connected in series disconnects the appliance at 85 °C to prevent
overheating. In mechanically controlled appliances, this temperature
switch is combined with a 65 °C temperature controller (A) and
housed in one module, in electronically controlled appliances it is
com-bined with an NTC sensor (A) (negative temperature coefficient)
and housed in one module. The sensor surface is in direct contact
with the detergent solution.
