GAUGE READINGS AND SETTINGS
Vacuum Gauge:
With vacuum port sealed, vacuum gauge should read 13-15 inches of mer-
cury. DO NOT exceed this level as damage to the blower will result. Do not run the machine
when vacuum is less than 6-8" (with the drain valve open for example). The machine needs
vacuum for the temperature control system to function.
Tachometer:
Reads the machine’s engine speed in revolutions per minute (RPM). With ma-
chine operating, it should read about 2200 RPM for single wand operation and 2700 RPM for
dual wand operation. The machine should not be operated at an engine speed under 1000 RPM
or over 3300 RPM or machine damage will result.
Temperature Gauge:
This gauge reads the water temperature at the outlet of the exhaust gas
heat exchanger when water is being drawn. The output temperature is adjustable by turning the
temperature control valve on the upper face panel. If very cool water is desired, the preheater
bypass valve can be opened.
