DANGER: FAILURE TO FOLLOW OEM INSTALLATION INSTRUCTIONS AND MAINTENANCE COULD RESULT IN A FIRE, OR AN
EXPLOSION THAT COULD CAUSE DEATH, PERSONAL INJURY, AND DAMAGE OF PROPERTY.
WARNING: IMPROPER MAINTENANCE CAN CAUSE INJURY OR DAMAGE EQUIPMENT THAT CAN AFFECT BENNETT PACIFIC
SERIES HYDROGEN DISPENSER PERFORMANCE.

IMPORTANT: The Honeywell Sensepoint XCD RFD Gas Technical Manual for Use Maintenance and Safety procedures must be
incorporated into the site’s maintenance and safety procedures. Refer to the original manufacturer’s documentation for
specified information. Note: Site documentation should be updated as changes arise (i.e. Regular replacement of sensor).
A non-purged dispenser utilizes a gas detection system that is used to detect flammable gas, toxic gas, and oxygen. Power will be
disconnected from the dispenser and the audio and visual alarm is activated if the level goes over 20%. Please refer to the Honeywell
Sensepoint XCD RFD Technical Manual located on your dispenser USB for detailed information.
Intended installation area for Dispensers protected by Flammable Gas Detector, including that the area is in an industrial establishment,

TIMER BOARD FOR PURGED SYSTEMS (LOCATED INSIDE JUNCTION B OX)
A purged dispenser prevents the buildup of explosive atmospheres in the electrical enclosure by using a blower to continuously introduce
air into the enclosure, maintaining a positive pressure differential of at least 0.15 inches of water. If the pressure drops to less than 0.15
inches of water column in the electronic enclosure, the pressure switch shown in
Figure 1.14 will turn off, causing a timer and relay shown
in Figure 1.13 to remove power from the dispenser until the pressure differential returns to 0.15 inches of water. During the delay, the
volume of air in the cabinet will be circulated at least 4 times and then power will be restored to the dispenser.
