SAFETY INSTRUCTION
This safety alert symbol will be used in this manual to draw attention to safety related instructions. When used, the
safety alert symbol means
ATTENTION! BECOME ALERT! YOUR SAFETY IS INVOLVED! FAILURE TO
FOLLOW THESE INSTRUCTIONS MAY RESULT IN A SAFETY HAZARD.
CAUTION:
All work must be preformed by quali
fi
ed personnel trained in the proper application,
installation, and maintenance of systems in accordance with all applicable codes and
ordinances.
CAUTION:
If the automatic
fi
lling unit is not installed, commissioned and maintained properly,
according to the instructions contained in this manual, it may not operate correctly
and may endanger the user.
CAUTION:
Make sure that all the connecting pipework is water tight.
CAUTION:
When making the water connections, make sure that the unit connecting pipework is
not mechanically overstressed. Over time this could cause breakages, with
consequent water losses which, in turn, could cause harm to property and/or people.
CAUTION:
Water temperatures higher than 100°F (38°C) can be dangerous. During the
installation, commissioning and maintenance of the automatic
fi
lling valve, take the
necessary precautions to ensure that such temperatures do not endanger people.
Leave this manual for the user.
CAUTION:
In the case of highly aggressive water, arrangements must be made to treat the water
before it enters the unit, in accordance with current legislation. Otherwise the unit may
be damaged and will not operate correctly.
Pre-adjustment
AutoFill automatic fi lling valves in the 5350 series come standard with
an operating adjustment knob and an integral downstream outlet
pressure gauge. This adjustment knob features rotational operation.
The pressure can be adjusted
continuously, resulting in 7 psi
per revolution, with the value
displayed on the outlet gauge.
