FH100 Precision Variable-Speed Peristaltic Pump System Operating Manual 4-1Cole-Parmer
Section 4 Maintenance
WARNING: Remove power from the pump before
attempting any maintenance.
The speed control circuit has solid-state components that do not require
service. An excessive load on the system may, however, cause the fuse to
blow. An indication of an excessive load is a switch that does not light
with power applied to the pump and when the ON-OFF switch is in the
ON position. If this condition occurs, remove power from the unit and
remove the fuse from the fuse holder located on the rear of the pump.
Replace the fuse with a fuse of the same type and rating. This information
is printed on the rear of the unit.
CAUTION: Replace the fuse only with one of the same
type and rating. The fuse rating and type are stated on
the rear panel.
DANGER: Remove power from the pump before any cleaning
operation is started.
Keep the pump enclosure clean by using a mild detergent solution. Never
immerse nor use excessive fluid when cleaning the pump.
