Amico Valve Alarm Combo Unit - Manual (Page 10)

CAUTION: The microprocessor circuitry on the alarm valve unit contains sophisticated integrated
semiconductors. If it becomes necessary to remove a module, PLEASE hold the boards by the edges.
DO NOT TOUCH any of the components on the board. Static discharge can cause the modules to
malfunction or become damaged.
Sensor
LOCAL (Inside the Back Box)
1. Locate the gas specific sensor module to be installed.
2. In the back box, there are colour coded gas labels located under
the DISS Demand check valves. Each label identifies where each
sensor module is to be placed.
3. The sensor module contains a gas specific DISS fitting. Push the
sensor module hex-nut and nipple adapter up into the demand
check-valve. With a wrench, tighten the nut so that it makes a
good seal.
NOTE: Pressure on sensors is not to exceed 250 psi for pressure
sensors and 30" for vacuum sensors
The sensor can reach pressure up to:
Mid Pressure 0-99 Psi
Hi Pressure 0-249 Psi
Vacuum 0-30" Hg
REMOTE (Outside the Back Box)
1. Connect a Tee (supplied by others) to the pipeline with a 1/4" NPT
female connection that will accept the DISS Demand check-valve.
2. Locate the gas specific sensor module to be installed.
3. Thread the DISS Demand check-valve into the correct gas
pipeline.
4. The sensor module contains a gas specific DISS fitting. Push the
sensor module hex-nut and nipple adapter up into the demand
check-valve. With a wrench, tighten the nut so that it makes a
good seal.
