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. If the fill
time exceeds 9 minutes, the EL6 control will display a WDT LEVEL EXP (watch dog timer) alarm,
indicating that the machine did not fill quickly enough. This watch dog timer is programmable –
see the EL6 Programming Manual, included with the machine, for further details.
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 33. SP-185 should use the next larger size pipe. Refer to table
4.4, 4.5, and 4.6 on page 34 for details on individual machine requirements.
Figure 4.14: Water Connection Detail
To avoid eventual water hammer in the water line, suitable devices to reduce the water hammer
should be installed.
4.9 Steam Connection
For machines equipped with optional steam heat, install piping in accordance with approved com-
mercial steam practices. Steam requirements are shown in the figure 4.7 on page 35. Failure to
install a steam filter/trap may void the warranty.
