It is also recommended that a shock absorber (not supplied with the models covered in this manual) be installed in the incom-
ing water line. This prevents line hammer (hydraulic shock), induced by the solenoid valve as it operates, from causing dam-
age 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 300XS is designed to use low pressure steam as a source of heat for wash tank water. The
machine comes 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.
CHEMICAL DISPENSING EQUIPMENT: The 300XLT machine requires that a separate chemical feeder be connected to it to pro-
vide the required detergent and sanitizer. This feeder needs to be able to operate against a head of 25 PSI and provide 1.79 ml of
a 10% Chlorine sanitizer per minute.
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 one(1) screw 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 (3 phase models only.)) to the appropriate
terminals as they are marked on the terminal block. Install the grounding wire
into the lug provided.
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 incom-
ing power at the terminal block and ensure it corresponds to the voltage listed on the data plate. If not, contact a qualified ser-
vice agency to examine the problem. Do not run the dishmachine if the voltage is too high or too low. Shut off the service break-
er 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.
