Fuse Replacement

The 115V AC LIQUID-SENSOR Controller uses a 10-A Slo-Blo fuse (3AG,
part number B-1115-0052), which is located in the fuse holder on the rear
panel. The 230V AC LIQUID-SENSOR Controller uses a 6.3-A fuse (5 x 20
mm, part number B-1115-0054), which is located in the drawer in the
POWER INPUT connector on the rear panel. Replace only with the correct
fuse.

Cleaning

Clean the top surface of the detector pad with a soft, dry cloth. If liquid cleaner
is used, rinse and dry thoroughly before resuming operation. Keep the
LIQUID-SENSOR Controller enclosure clean by using a mild detergent.
Never immerse or use excess fluid.
