DETERGENT, RINSE AID, SANITIZER DISPENSERS – Equipment Connections
Electrical and grounding connections must comply with the applicable portions of
the National Electrical Code, NFPA 70 (latest edition) and / or other local electrical codes.
Disconnect the electrical power to the machine (both dishwasher and booster if
applicable) and follow lockout / tagout procedures. Be sure all circuits are disconnected.
This machine must be operated with an automatic detergent feeder and, if applicable, an automatic chemical
sanitizer feeder, including a visual means to verify that detergents and sanitizers are delivered or a visual or
audible alarm to signal if detergents and sanitizers are not available for delivery to the respective washing
and sanitizing systems. Refer to the installation section of this manual and to the chemical feeder equipment
manual(s).
Detergent Dispenser
(Figure 15)
Terminals DPS1 and DPS2 are supplied with controlled machine line voltage. They are ON during the wash
cycle and OFF between cycles or when the machine power supply is OFF. Maximum rating for detergent dis-
penser connected to DPS1 and DPS2 is 1.5 Amps at line voltage. Check the machine supply voltage and use
corresponding feeder transformer voltage. Use UL Listed 600 volt minimum insulated wire for the connections.
Do not use bell wire, lamp cord or similar type wire. Splice connections, if required, must be made in the
feeder transformer junction box - not in the main controls enclosure. Remove
