pers provided as follows: one jumper between terminals 1
and 2, one between terminals 3 and 4 and another
between terminals 5 and 6. Using a suitable power supply
cable, connect the three phases to terminals 1, 3, 5, and
the earth wire to the terminal
.

Safety devices
• An automatic resettable thermally protectived device
incorporated in the windings of the electric pump cuts
off the electricity supply in the case of malfunctioning.
• In the event of water mains failure, a back-flow
device prevents water in the boiler from returning into
the mains.
• An overflow pipe, connected to the drainage outlet,
maintains the water in the tank at a constant level.
• On models with a drain pump, a supplementary level
control device activates if the main level control
device is faulty.
Failure to comply with safety rules and regulations
relieves the manufacturer of all liability.

WARNING MESSAGES DISPLAYED ON THE
CONTROL PANEL
NO WATER
- Check that the shutoff valve is open.
- Check that the water inlet filter is clean.
- Check the minimum main pressure is not less than
7.25 psi/50kPa.
- Check that the overflow pipe is inserted (for applian-
ces without drain pump only).
INSUFFICIENT DRAINAGE
- Check if the overflow has been removed.
WARNING
Before servicing unit switch off power at
the main circuit breaker and place a red

ses the boiler heating elements are
disconnected. Using the dishwasher in
these conditions may increase the cycle
time.
