5.4 Deliming (as required)
Lime scale deposits will occur over time on
the interior of the dishwasher if it is operated
using a hard water supply. Meiko recommends
a hardness of 4 grains per U.S. gallon (7 DH
German hardness).
A deliming or de-scaling process can be used
to remove these deposits, as well as any
accumulated food residue.
When deliming the interior, be sure to follow
these guidelines:
• Use deliming agents designed for use with
commercial dishwashers.
• Follow the instructions for the deliming
agent that is used.
• Start the machine as described in Sec-
tion 4, Operation.
• After the deliming procedure, continue to
run the dishwasher for at least 10 min-
utes to rinse the interior thoroughly. Cycle
empty racks through the machine as nec-
essary to keep the pumps in operation.
• Press to shut off the machine. Switch
the circuit breaker/fused disconnect to the
OFF position.
• Move the drain handles to the DRAIN
OPEN position.
• Remove all scrap screens, wash arm
manifolds, prewash arms (if so equipped),
auxiliary rinse and final rinse arms. Clean
them as described in Sections 5.1 and 5.2
of this Manual.
• Inspect the interior for any remaining
deliming agent residue. If residue is
present, remove it using a soft cloth and
hot water.
• Thoroughly flush the interior of the
dishwasher using warm water from a low-
pressure hose or spray nozzle.
CAUTION
Never use a high-pressure water spray
when cleaning the machine.
• Leave the doors of the machine open to
allow the interior to air dry thoroughly.
• Reassemble all components into the dish-
washer before operation.
WARNING!
Ensure that ALL residue of the
deliming agent is removed. Residue
from the agent can:
- Pose a health hazard;
- Damage seals and plastic compo-
nents inside the dishwasher.
