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.

NOTICE: This machine must be operated with an automatic detergent feeder and, if applicable, an automatic
chemical sanitizer feeder, including a visual means to
verify that detergents and sanitizers are delivered or a
visual or audible alarm to signal if detergents and sanitizers are not available for delivery to the respective
washing an sanitizing systems. Please see instructions
for electrical and plumbing connections located in this
manual and in the feeder equipment manual.
For connections, see the wiring diagram.
Example:
Supposing that an external detergent dispenser has
been connected with a tank concentration measuring
sensor, a standard setting could be as follows:
dIn=0 the dispenser is not activated during filling of
the tank.
dEt=181 the dispenser is activated during wash
pump operation and, thanks to the concentration measured by the conduction sensor, the correct amount of
detergent is dispensed.
Suggestion: to check the effectiveness of the rinse-aid,
look at freshly washed glasses against the light. Drops of
water remaining on the glass indicate an insufficient
amount, while streaks on glass indicate an excess
amount.

DELIMING
WARNING
AGENTS OR ANY OTHER KIND OF ACID MUST
NOT COME IN CONTACT WITH BLEACH OR
RINSE SOLUTION CONTAINING BLEACH USED
IN CHEMICAL-SANITIZING MACHINES. MIXING
MAY CAUSE HAZARDOUS GAS TO FORM. THIS
ENTIRE PROCEDURE MUST BE FOLLOWED
STEP BY STEP FOR SAFE AND SATISFACTORY
RESULTS.
DELIME THE POTWASHER ON A REGULAR BASIS
AS REQUIRED. The regurarity will depend on mineral
content of the supply water. Deliming should be done
when you can see clear signs of lime deposits (a white,
chalky substance) on the inside walls and on the wash
arms. If deliming is necessary, a deliming agent should
be used for best results.
