INSTALLATION PROCEDURES
3-7
The machine should be connected to an individual branch circuit not shared with lighting
or other equipment.
The connection should be shielded in a liquid tight or approved flexible conduit with proper
conductor of correct size installed accordance with National Electrical Code (USA) or other
applicable codes. The connection must the wiring diagram provided with the machine. See the
Electrical Connection data Chart for correct wire sizes.
Use wire sizes indicated in the chart for runs up to 50 feet (15 m). Use next larger size for
runs of 50 to 100 feet (15 – 30 m). Use 2 sizes larger for runs greater than 100 feet (30 m).
For personal safety and for proper operation, the machine must be grounded in accordance
with state and local codes and in the USA in accordance with the National Electrical Code, article
250 – 96.
The ground connection must be to a proven earth ground, not to conduit or water pipes. Do
not connect the system is used, the neutral (N) leg at the terminal strip.
If a DELTA supply system is used, the high leg may be connected to L1, L2 or L3, as the
machines are equipped with control transformer.
Individual hot and cold plumbing lines with individual shut – off valves must be available
to the machine. Hot water should be minimum of 160 ºF (70 ºC). If lower temperature water is used
the machine should be equipped for steam heating to heat the wash solution to desired temperature.
Best performance will be realized if water is provided at a pressure of 30 – 85 psi (2 – 7 bar).
Although the machine will function properly at lower pressures, increased fill times will occur.
Flush the water system for at least two minutes prior or initial use.
Use flexible hoses and install separate screen filters in the lines to keep rust and other
foreign particles out of the solenoid valves. Hang the hoses in a large loop. Do not allow the hoses
to link. The water connections to the machine should be supplied by a hot and cold water line of
least the sizes shown in the table below. Installation of additional machines will require
proportional larger water lines, see table.
To avoid eventual water hammer in the water line, suitable devices to reduce the water
hammer should be installed.
