16 Water connection
The water-related safety should be as per DIN EN 61770. The machine can be connected to an inlet water supply without an intermedi-
ate connection to other safety equipment.
Warning
The machine and any other relevant additional devices must be connected by an authorised specialist company in
relation to local standards and regulations.
16.1 Requirements for the on-site inlet water connection
Water quality The fresh water must in microbiological aspects have the quality of drinking water.
Water inlet temperature max. 60°C
max. 20 °C for Cool, EnergyPlus and ClimatePlus machine models
max. 50 °C for effect glasswasher models
Water hardness
We recommend a maximum hardness of 3 °dH (3.8 °e / 5.34 °TH / 0.54 mmol/l), to prevent scaling in
the machine.

easily accessible

not behind the machine

3/4" connector
16.3 Connecting the supply hose
Caution
The supply hose may not be shortened or
damaged.
Old existing hoses may not be re-used.
Do not bend the supply hose while laying it.
The supply hose and dirt trap are located in the machine.
INFO The dirt trap prevents particles from the water supply
line entering the machine thus preventing extraneous
rust on the cutlery and in the machine.
Right view

Connect the supply hose (TWw) to the machine.

Connect the dirt trap to the on-site water stop cock.

Connect the supply hose to the dirt trap.

Open the water stop cock and test whether the connections
are tight.
16.4 Connecting the drain hose
Caution
The drain hose may not be shortened or dam-
aged.
Do not bend the drain hose when laying it.
The drain hose is located in the machine.
INFO The machine is equipped with a drain pump. The on-
site water drain must have a trap. The maximum height
of the on-site water drain is 650 mm.
Back view

Connect the drain hose (A) to the machine.

Connect the drain hose to the on-site water drain.
