BOILER CONTROLS — GAS (Figs. 2, 3) or ELECTRIC (Figs. 2, 4)
Power Switch
• Press [ I ] to power the controls and begin filling the
boiler.
• Press [ O ] to turn the controls and the steamer off.
The boiler automatically blows down for about 5
minutes.
High Pressure Light
• Is lit after [ I ] is pressed and stays on during fill. Goes
off after the reset switch is pressed (when green light
is lit).
• Is lit if pressure exceeds 15 psig.
Low Water Light
• Is lit after [ I ] is pressed and stays on during fill. Goes
off after the reset switch is pressed (when green light
is lit).
• Is lit if water level is too low.
Reset Switch
• When the high pressure and low water limits are
satisfied, the green light in the reset button will come
on. Press the reset button to clear high pressure and
low water limit lights and start or resume normal
operation.
Boiler Pressure Gauge
• Indicates the boiler steam pressure; the normal
operating range is 5 to 12 psig.
Water Level Gauge
• The correct water level is approximately 1" (
2.5 cm) of water in the water level gauge sight
glass.
• The manual valves at the top and bottom of the water level gauge (Fig. 3) must be fully open
(counterclockwise).
• Observe that the water is clean and clear in the glass tube.
– The appearance of extreme murkiness in the water indicates inadequate water quality
and will cause the controls and the steamer to fail. Warranty does not cover malfunction
due to poor water conditions.
Pressure Relief Valve
• The pressure relief valve, located on the top left side, prevents pressure in the boiler from
exceeding 15 psig.
• Manually pull up the lever daily to reduce scale buildup and verify that the pressure relief valve
functions properly.
