It is essential to fit a main stop tap on the water intake deliver pipeline; the tap must be accessible
after installation of the appliance, so do not install it behind the warewasher. The stated cycle
duration applies to appliances supplied with hot water >50°C<60°C If the warewasher is supplied
with cold water, the cycle duration might increase depending on the intake water temperature.
The warewasher is fitted with a drain pump and can operate with drain connections on the floor or
wall.
Refer to the connection diagram for the maximum permitted height of wall drains – (see TECHNICAL
DATA)
Caution: make sure that the intake and drain hoses are not bent, constricted or crushed
after installation.
When installing the drain hose to a siphon with valve, the maximum height of the drain outlet is
reduced to 600 mm.
