Mounting
Low Gas Pressure Models
Low gas pressure switches break the electrical circuit on
pressure drop at the point when gas pressure becomes
lower than the indicated set pressure.
Before the manual reset button (Figure 6) can be prop-
erly latched, gas pressure in the chamber must be higher
than the indicted setting. The position of the yellow ring,
on the reset button, shows whether the reset button is on
or off. If the yellow ring on the button is below the cover,
the unit is on (not latched). If the yellow ring is above
the cover, the unit is off (latched). The yellow ring must
be below the cover after latching to be properly set.
High Gas Pressure Models
High gas pressure switches break the electrical circuit
when pressure rises above the indicated preset pres-
sure. The yellow ring will be below the cover, indicating
that the switch is on, when the gas pressure in the switch
chamber is below the indicated high setting. When the
yellow ring on the reset button is above the cover, it indi-
cates the switch is in the off position, and gas pressure is
above the indicated setting.
Range Adjustment - All Models
To adjust gas pressure cut-off setting, remove the cover.
Turn the range scale adjustable knob (Figure 6) clock-
wise to increase pressure setting, counterclockwise to
decrease pressure setting. Install cover and tighten the
two cover screws to prevent tampering.

SUGGESTIONS
All switches can be mounted in either horizontal or
vertical position. Switches should be reasonably level
but do not required accurate leveling.
Single gas switch models have a 1/4” N.P.T. (female)
gas inlet on the standard base.
Piping can be either standard black pipe or
aluminum tubing.
All switches can be supported by the inlet pipe, but
optional mounting brackets and bases are available (see
Figures 1 thru 5 below).
Switches have been factory calibrated and tested for
leaks. However, it is recommended that switch, gas pipe
inlets and connections be soap bubble tested for leaks
after installation.
