SAFETY

The procedures in this section must be performed with power removed from the dispensing system. Attempting to
perform the procedure without power removed can result in serious injury or death. If you are unsure of the status of
electrical power, DO NOT perform the procedure. The capacitors in the power supply section of the pump drive maintain
high voltage for up to ten minutes after power is removed. Allow sufficient time for the capacitors to discharge before
removing the cover for servicing.
Refer to USER-REPLACEABLE PARTS for the part numbers of all the user replacement parts.

CLEANING

WARNING: Disconnect the dispenser from the AC source before cleaning. A shock hazard exists when using
water on powered equipment.
Keep the dispenser enclosures clean by using a mild detergent and water solution. Never immerse the unit in water or
use excessive fluid when cleaning the dispenser. Dry the dispenser before restoring power.

FUSE REPLACEMENT

If you suspect that the fuse has blown, use the following
procedure to remove, check, and replace the fuse.
CAUTION: Always replace the fuse with the same
type and rating as the blown fuse. Using a
fuse of a different type or with a different
rating can cause damage to the pump
drive.
1. Unplug the power cord from the AC source.
2. Ensure that the power switch is in the Off (O) position,
and remove the power cord from the back of the pump
drive.
