Installing An External Solid Or Liquid Detergent System; Installing An External Liquid Rinse Aid System - Meiko K-200 Owner's Installation, Operation And Maintenance Manual

S 3 - I
ECTION NSTALLATION
The machine is equipped with:
• A pre-plumbed tubing raceway exiting the
machine at the load end of the machine
(see Figure 3-8). The raceway is routed to
deliver detergent into the wash tank. Solid
or liquid detergent lines can be routed
down the raceway and into the tank.
• A dummy plug in the floor of the wash tank
that permits the installation of a detergent
concentration probe.
• A final rinse plenum chamber with a fitting
for a liquid rinse aid line (see Figure 3-9).
A threaded pipe connection just below the
plenum allows the installation of a final
rinse pressure switch.
A dispensing system terminal block inside the
control box of the machine provides contacts
for two line voltage relays. These relays,
when closed, provide a "window" for external
pump systems to activate.
Pump activation can be controlled as follows:
• Solid detergent systems should use a probe
installed in the wash tank to measure de-
tergent concentration and allow activation
of the external pump. A dummy plug in
the bottom of the wash tank provides an
installation location for the probe.
• Liquid detergent systems can use EITHER
a detergent concentration probe, OR a
timer system. A detergent concentration
probe is HIGHLY RECOMMENDED.
• Liquid rinse aid systems should use a
rinse line pressure switch so that rinse aid
is dispensed only when the final rinse is
in operation. A 1/4" NPT female threaded
connection is provided in the rinse aid line
just below the final rinse plenum chamber.
The pressure switch should be installed
at this location.
3.9 Installing an External Solid or Liquid
Detergent System
1. Locate the detergent line connection at the
load end of the machine. See Figure 3-8.
2. Route the detergent supply line to the
opening, completely down the raceway
and into the wash tank.

CAUTION
Make sure that the detergent line runs
completely down the raceway to the wash
tank. The raceway is NOT watertight, and
is NOT intended to be a tube for chemicals!
3. Fasten the line in place and seal the
connection.
4. If a detergent concentration probe will be
used, remove the dummy plug in the
bottom of the wash tank. Then, install the
detergent concentration probe and seal
the connection.
5. Check that the pump is correctly installed
according to the manufacturer 's
instructions.
3.10 Installing an External Liquid Rinse Aid
System
1. Route the rinse aid supply line to the fitting
on the side of the final rinse plenum chamber
and fasten it in place. See Figure 3-9. Check
that the connection is secure and seal it.
2. Install a rinse pressure switch to the 1/4"
NPT female pipe connection just below the
final rinse plenum chamber.
3. Check that the pump is correctly installed
according to the manufacturer's instructions.
