7.1.3 Requirements for the waste water connection
A waste water pump is integrated into the drain pump.
• Connect the drainage hose to the locally available waste water pipe.
– For Australia only:
The drain hose must be connected such that it is watertight with a drain fit-
ting in accordance with AS 1589 AS 2887 and a sanitary waste water pipe
or sanitary waste water fitting in accordance with AS / NZS 1260.
• Depending on the cleaning and disinfection machine application, a grease trap
may be included, based on the general/location-specific regulations.
• For cleaning and disinfection machines with GiO MODULE, the maximum drain
height must be considered (see dimensional drawing).
7.1.4 Requirements for the compressed air connection
• On-site compressed air connection for respiratory protection devices (between
2 and max. 5 bar) in accordance with EN 12021.
• Specification of the authorised pressure range: operating pressure 2 to max. 5
bar.
If loud noises occur that are not typical of operation, the malfunction must be
repaired without delay. Comply with the general rules for working with com-
pressed air (wear hearing protection, if necessary).
7.1.5 Requirements for the fresh water connection
Fresh water connections and their components must be carried out in accord-
ance with local regulations, e.g. EN 1717/DIN 1988-100. The fresh water must
be of the same quality as drinking water in microbiological terms. This also
applies to processed water.
The basic model of the washer-disinfector features an air gap (type AA or AB as per
EN 1717 or EN 61770). In the case of SVGW (Switzerland) and other countries, a
type EA safety device (at least) is also required in front of the connection hose, de-
pending on the machine version. Installation components and materials must be
suitable and permitted in accordance with local regulations. A solenoid valve is inte-
grated into the cleaning and disinfection machine's fresh water pipe. This, together
with the leakage detector in the base drip tray in the subframe, ensures that in the
event of a leak within the machine, the fresh water inlet is shut off.
Pressure range of the fresh water supply flow pressure upstream of the solenoid valve:
• Machines with air gap or pressure booster pump:
60
– 500 kPa (0.6 – 5 bar)
• Machines with a safety device to prevent backflow:
250
– 500 kPa (2.5 – 5 bar)
Maximum pressure
• Do not exceed maximum pressure of 500 kPa (5 bar).
Measures to ensure correct water pressure:
• If the minimum flow pressure is too low, increase the pressure using a pressure
booster pump.
• If the maximum pressure is exceeded, limit the pressure using a pressure regu-
lator.
Other measures:
• Ensure that no foreign iron particles can enter the appliance via the fresh water
connection. The same also applies for contamination by other metal particles
(e.g. copper shavings). Corresponding instructions are contained in the assem-
bly plan.
• A dirt trap must be fitted in the fresh water supply to protect the solenoid valve.
• After the washer-disinfector has been unused for longer periods of time, drain
the connection pipe and clean it before placing the machine in operation again.
• When replacing an old machine with a new one, make sure that the existing
feed hose is exchanged for the new feed hose supplied with the machine.
