Please read this instruction sheet 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 an interlocking switch
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 housing for leaks
with a soap bubble test. All exhaust fans and
blowers should be inspected and checked for
proper rotation prior to starting up. If you have any
problems or questions, phone, fax, email or write to
the manufacturer, Antunes Controls.
