For machines equipped with factory internal
chemical dispensing systems, prime the lines
as follows:
1. Press and hold the
key until

3.15 Checking for Correct Chemical
Concentration
Machines equipped with external chemical
dispensing systems will have normal settings
recommended by the manufacturer.
For machines equipped with factory internal
chemical dispensing systems, the normal
settings for chemical injection are:
•
Detergent - 0.256 oz. per gallon of wash
water (2.0 ml per liter).
•
Rinse additive - 0.0256 oz. per gallon of
rinse water (0.2 ml per liter).
To check if the normal settings are correct for
your chemicals,
RUN THREE EMPTY
LOADS
to completely cycle the water supply
and obtain accurate test results. This will only
take a few minutes. Then, run a sample load
with soiled ware and examine the results.
•
If the detergent setting is too low, the ware
will not be adequately cleaned. In some
cases, this can be corrected by simply
selecting a longer cycle time (using the
Cycle Select II, Extended or Cycle Select
III, Heavy buttons), but the detergent
concentration may also need to be adjusted.
•
If the rinse additive setting is too low,
spotting or streaking may occur on the
ware.
•
If too much of either chemical is added,
the extra chemicals will be wasted. This
is often difficult to detect except by
determining how long your chemical
supplies last. If the chemicals are being
exhausted quickly, you may need to have
the chemical concentration adjusted.
IN ALL CASES, ANY ADJUSTMENTS OF
THE FACTORY CHEMICAL INJECTION
SETTINGS ARE TO BE PERFORMED
ONLY BY A MEIKO AUTHORIZED
SERVICE AGENT. CHANGES BY
UNAUTHORIZED PERSONNEL WILL
VOID YOUR WARRANTY.
