now cold and in liquid form, can once again absorb the heat from the machine's exhaust
air which causes the coolant to evaporate in the process.
The equivalent energy needed to drive the pump is only about one third of the energy
which can be recovered in the form of heat from the machine's exhaust air.

14.19 Separation from the water mains

In accordance with DVGW (The German Gas and Water Industry Association)
regulations, the clean water rinse system is completely separated from the building's
water supply system in order to prevent the undesirable return of water containing
chemicals or contaminants caused by back pressure.
This is achieved with the aid of a water tank which is filled from the mains by a ball valve.
The possibility of return to the mains by back pressure is avoided by the fact that the
water enters the tank via an air gap. Even when the water is at its highest possible level
in the tank, the discharge pipe of the incoming water supply lies above the surface of the
water in the tank. A ball valve controls the entry of water.
A booster pump removes the required volume of clean water from the tank and,
depending on the machine model, pumps it either directly or via a heat recuperator into
the rinse system. The quantity is regulated by means of an orifice plate located in the
pump outlet side.

14.20 Rinse agent mixing chamber

The "Chemical Saving System" CSS+)
This machine is equipped with a new type of highly efficient mixing chamber to reduce
the consumption of rinse agent for the clean water rinsing. The chamber is located in the
water system for the rinsing equipment, between the flow heater (F-KSP) and the
ascending pipe. The rinse agent is injected via a tangential injection nipple.
The principle purpose of the mixing chamber is to mix the rinse agent (which is normally
injected at intervals by the dosing pump) optimally with the clean water so that rinse
agent and water are uniformly mixed. Optimal mixing is achieved by deliberately induced
turbulence between the water and the rinse agent injected by the pump.

15 Tips for self-help in the case of faults

Fault:
Machine does not fill.
Fault:
Rinse water does not
spray.
