4.8 Water Connection
Individual hot and cold plumbing lines with individual shut-off valves must be available to the
machine. Hot water should be minimum of 160F (70C). If lower temperature water is used the
machine can 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 to 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 kink.
The water connections to the machine should be supplied by a hot and cold water line of least the
sizes shown in table 4.14 on page 28.
