Connecting Chemical Containers Or Dispensers; Fresh Water Supply Connection(S) - Meiko K-44E Owner's Installation, Operation And Maintenance Manual

3.13 Connecting Chemical Containers or
Dispensers
This section applies to units with either inter-
nal or external chemical dispensing pumps.
1. Check that the rinse additive and
detergent are compatible with the unit. In
particular, a commercial (not a domestic)
detergent MUST be used.
2 Check that the containers/dispensers are
correctly installed according to the
manufacturer's instructions.

3.14 Fresh Water Supply Connection(s)

CAUTION
Before connecting the water supply line, it
MUST be flushed clean of all debris, including
(but not limited to) pipe sealant, metal particles,
solder, etc. This debris can damage the appliance.
IMPORTANT
In some cases, local codes dictate that water
supply connections be made only by a
certified professional.
The water supply connection(s) for the dish-
washer are located behind an access panel
on the unload end of the machine. All connec-
tions are 3/4" female NPT. See Figure 3-10.
1. Check that iron or other metal particles
cannot contaminate the fresh water
supplied to the dishwasher.

2. Check the incoming water temperature.
• Units without a prewash section (K-44,
K-54, K-64) have one incoming water
connection, which must be 180°F.
• Units with a prewash section (K-66, K-
76, K-80, K-86, K-90, K-100) have two
incoming water lines. The line for the
final rinse connection must be 180°F.
The line for the prewash connection
must be 110-140°F.
3. Check the incoming water hardness.
Meiko recommends a hardness of 4-6 grains
per U.S. gallon (7 DH German hardness).
4. Because the water inlet incorporates a
stainless steel dirt trap, an additional trap
is unnecessary unless required by local,
national or international codes.
5. Connect the customer-supplied water
line(s) to the appropriate connection(s). Fill
line connections are 3/4" NPT female.
6. Check the incoming water pressure at the
final rinse pressure gauge, as shown in
Figure 3-11. The machine requires a
pressure of 15-25 psi at the final rinse for
correct operation. It may be necessary to
increase the pressure (with a booster
pump) or to reduce the pressure (with a
reducing valve).
