Connections provided for energy control.
This appliance is designed for an external energy con-
sumption control.
Connect the energy peak controller across terminals 11
and 12.
CAUTION
!
A normally open (n.o.) contact of the
controller must be connected across
terminals 11 and 12. When this contact
closes the boiler heating elements are
disconnected. Using the dishwasher in
these conditions may increase the cycle
time.
Safety devices
• An automatic reset thermoamperometric protective
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 device pre-
vents 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 con-
trol device is faulty.
Failure to comply with safety rules and regulations
relieves the manufacturer of all liability.
B3 DETERGENT/RINSE-AID DISPENSERS AND
SETTINGS
If the appliance is connected to a water softener or
osmotic device, contact the detergent supplier for a
specific product.
Peristaltic dispensers (rinse-aid and detergent) require
periodic maintenance. The internal hose of the rinse-
aid dispenser should undergo periodic maintenance
(at least once or twice a year).
1. Dishwasher with incorporated detergent dis-
penser pump (Figure 13).
Pump "R" dispenses about 0.9 g/s of detergent. When
the appliance is filled with water for the first time in the
day, it dispenses about 44 g of detergent in 45 sec.,
thereby providing a concentration of 2 g/l. Pump "R"
dispenses about 6 g in 6 sec. at each cycle.
. Dispenser operating time may be changed, following
the instructions given in the next paragraph.
