Versa Plus Gas Pressure Switches
Versa Plus Gas Pressure Switches by Antunes Controls
monitor gas pressure and break the electrical control
circuit when pressure drops below or rises above the
desired setpoint. The gas pressure settings are adjustable
and available in manual or automatic reset operation.
These switches are sturdy and constructed with a dura-
ble plastic electrical enclosure and a die-cast aluminum
inlet base.

IMPORTANT
Please read these instructions carefully to assure
correct installation. This equipment must be
installed only by a licensed electrician who is
experienced with combustion safeguard control
systems and understands the functions of inter-
locking switches, such as gas pressure switches.
Prior to being put into operation in conjunction
with the combustion safeguard systems, all
switches should be tested for proper range setting
and proper wiring. Check piping connections and
switch house for leaks with a soap bubble test. All
exhaust fans and blowers should be inspected and
checked for proper rotation prior to starting up.
