Do not store this manual inside the detector, as this
might result in damage to components from excessive
heat
.
Adequately cover the detector sensor during washdown and avoid
spraying the washdown liquid directly onto the sensor. If necessary,
an ABS wash down tube is available from the factory.
A nuisance alarm will also occur if the external temperature sensor
installation status is programmed to “F In” (installed) and an
external temperature sensor is not installed.

The Cool Air Incorporated LBW-420 Family of Detectors is a state-
of-the-art ammonia leak detector that detects and displays ammonia
concentrations of 0 to 500 parts per million (PPM) electrochemical
sensor or 0 to 1000 parts per million (PPM) solid state sensor.
The Cool Air Incorporated LBW-420-2 is a 230VAC powered
version of the LBW-420 ammonia leak detector (115VAC powered
detector). The LBW-420-2 requires an AC supply voltage between
200 and 240 volts AC.
The Cool Air Incorporated LBW-420-1 is a DC powered version of
the LBW-420 ammonia leak detector (AC powered detector). The
LBW420-1 incorporates a fully isolated DC to DC power supply,
allowing the LBW-420-1 to be powered from the same DC supply
as the 4-20 mA monitoring circuits without concern for ground
isolation.
The LBW-420-1 requires a DC supply voltage between 18 and 36
volts DC.
The LBW-420-1 can be configured to supply power to the 4-20 mA
circuit(s) or can operate as a fully isolated 4-20 mA sensor. Refer
