INSTALLATION & OPERATION
INSTALLATION INSTRUCTIONS
WATER SUPPLY CONNECTION: Read the section entitled "PLUMBING THE DISHMACHINE" before proceeding. Install
the water supply line (3/4" pipe size minimum, 1/2" pipe size minimum for LT) to the dishmachine line strainer using cop-
per pipe. It is recommended that a water shut-off valve be installed in the water line between the main supply and the ma-
chine to allow access for service. The water supply line is to be capable of 20±5 PSI "flow" pressure at the recommended
temperature indicated on the data plate. Take care not to confuse static pressure with flow pressure: Static pressure is line
pressure in a "no flow" condition (all valves and services are closed); flow pressure is the pressure in the fill line when the
valve is opened during the cycle. It is suggested that a shock absorber (not supplied) be installed on the incoming water line.
This prevents water hammer (hydraulic shock)—induced by the solenoid valve as it operates—from causing damage to the
equipment.
PLUMBING CHECK: Slowly turn on the water supply to the machine after the incoming fill line and the drain line have been
installed. Check for any leaks and repair as required. All leaks must be repaired prior to placing the machine in operation.
STEAM LINE CONNECTION: The steam machines come with lines by which the source steam needs to be connected.
Connect all steam lines to the machine as all applicable codes provide. See machine data plate for information concerning
steam flow pressure.
ELECTRICAL POWER CONNECTION: Electrical and grounding connections
must comply with the applicable portions of the National Electrical Code ANSI/
NFPA 70 (latest edition) and/or other electrical codes. Disconnect electrical
power supply and place a tag at the disconnect switch to indicate that you are
working on the circuit. The dishmachine data plate is located on the right side
and to the front of the machine. Refer to the data plate for machine operating
requirements, machine voltage, total amperage load and serial number. To
install the incoming power lines, open the control box. This will require taking a
Phillips head screwdriver and removing the four (4) screws on the front cover
of the control box. Install 3/4" conduit into the pre-punched holes in the back of
the control box. Route power wires and connect to power block and grounding
lug. Install the service wires (L1, L2, & L3 (three phase only)) to the appropriate
terminals as they are marked on the terminal block. Install the grounding wire
into the lug provided. Tighten the connections. It is recommended that "DE-OX"
or another similar anti-oxidation agent be used on all power connections.
VOLTAGE CHECK: Ensure that the power switch is in the OFF position and apply power to the dishmachine. Check the
incoming power at the terminal block and ensure it corresponds to the voltage listed on the data plate. If not, contact a
qualified service agency to examine the problem. Do not run the dishmachine if the voltage is too high or too low. Shut
off the service breaker and mark it as being for the dishmachine. Advise all proper personnel of any problems and of the
location of the service breaker. Replace the control box cover and tighten down the screws.
