RETROFIT INSTRUCTIONS FOR OLD-STYLE FLOAT SWITCH
WARNING: Inspection, testing and repair of electrical equipment should only be performed by a qualified
service technician. Many of the tests require that the unit have power to it and live electrical components be
exposed. USE EXTREME CAUTION WHEN TESTING THE MACHINE.
1. Turn of machine. The power button for the machine is indicated as Item A in the figure above. In addition to turning the power
off at the power switch, power must be secured at the service breaker. Lock out and tag out the service breaker to ensure that
power is not accidentally restored to the unit during the retrofit process. Before beginning any work, verify that there is no
electrical power coming to the dishmachine!
2. Secure water to the dishmachine. If your WH-44 model has a manual shut-off valve (refer to Item C in the figure above) then
shut that valve as well. Item C above shows the electric solenoid valve found on auto-fill models, but the manual fill valve should
be in the same relative location.
