WARNING
This retrofit kit requires drilling in a Hazardous Location. Insure that all power to the dispenser
has been turned off. Open all access doors for increased airflow. Use only sharp drill bits; dull
bits may generate excessive heat. Use air powered drill at low RPM’s. If an electric drill is
used, a suitable UL Listed Gas Detector must be used to ensure the area is below 25% of the
Lower Explosive Limit. Do not drill if gasoline odors are present.
If drilling in the electronics cabinet, carefully collect and remove all metal shavings that may be
inside the cabinet. Failure to remove the shavings could result in an electrical shock hazard.
Before drilling, check to ensure that no wires or fluid containing parts (i.e. product tubing) is
located on the backside or near the chuck of the drill.
