Mounting
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” NPT (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.
Operation
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 can be properly 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 pressure.
The yellow ring will be below the cover, indicating that the
switch is on, when the gas pressure in the switch cham-
ber is below the indicated high setting. When the yellow
ring on the reset button is above the cover, it indicates 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 clockwise to
increase pressure setting, counterclockwise to decrease
pressure setting. Install cover and tighten the two cover
screws to prevent tampering.
