1. FUEL PRESSURE GAUGE
The fuel pressure gauge indicates fuel oil
pressure to burner.
2. HOUR METER
The hour meter records the number of hours the
unit has run. This serves as a time recorder for
servicing the machine.
3. TEMPERATURE GAUGE
This valve enables additional heat exchangers
to contribute more heat to the system if
necessary. By rotating the lever to the right it
adds more heat, by rotating to the left it removes
heat.
4. CHEMICAL SELECTOR VALVE
This valve allows the chemical to circulate
through the chemical system with little or no
restriction for priming of system. It also purges
out air that may be trapped in the lines and
cavities of the chemical system. By turning
clockwise the injection system is enabled.
5. CHEMICAL METERING VALVE
The chemical metering valve regulates the
amount of chemical that is injected into the
system. Clockwise rotation of the knob closes
the valve. Counter clockwise rotation opens the
valve, allowing more chemical to enter the
system.
6. VACUUM INLET
The vacuum inlets serve as connecting point for
vacuum hoses.
