5.3 Exterior cleaning (as required)

CAUTION
When cleaning the exterior of the dishwasher,
be sure to follow these guidelines:
• A commercial stainless steel cleaner can
be used on exterior body panels. Follow
the manufacturer's directions.
• Meiko strongly recommends using deter-
gent, instead of a stainless steel cleaner,
when cleaning the control panel of the unit.
These chemicals can damage the gauges,
lights and labels.
• Never use abrasive cleaners or pads when
cleaning the exterior of the dishwasher.
These can scratch the surface of the unit.
WARNING!
Ensure that detergents and stainless
steel cleaners are kept out of the inte-
rior of the dishwasher. If the interior of
the unit requires cleaning, refer to the
deliming procedures (Section 5.4).

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:
•
This activates the conveyor and the wash
pumps, but does NOT activate the final
rinse. Final rinse activation adds fresh
water to the machine, which interferes with
the deliming process.

Switch the AUTO/
MANUAL switch to
the MANUAL
position.
• Use deliming agents designed for use with
commercial dishwashers.
• Follow the instructions for the deliming
agent that is used.
• After the deliming procedure, continue to
run the dishwasher in MANUAL mode for
at least 10 minutes to rinse the interior
thoroughly.
•
• Switch the POWER switch to the OFF po-
sition. Pull the external drain handle(s) to
drain the machine.
• Remove all scrap screens, baskets, wash
arm manifolds, prewash and recirculating
rinse arms (if so equipped), and final rinse
arms. Clean them as described in Sec-
tions 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.
Switch the AUTO/
MANUAL switch to
the AUTO position.
