temper ature
Where under normal operating conditions the limit of
68°c / 155°f (Restricted Zone) for normal touch, or
8 0°c / 176°f (Unrestricted Zone) for unintentional touch,
may be experienced, steps should be taken to minimize
contact or warn operators/users that normal operating
conditions will be exceeded. In certain cases where the
temperature of the pumped liquid exceeds the above stated
temperature levels, pump casing temperatures may exceed
10 0°c /2 12°f and not withstanding pump insulation tech-
Series 4300, 4360 and 4380

Pumps not immediately placed into service, or removed from
service and stored, must be properly prepared to prevent
excessive rusting. Pump port protection plates must not be
removed until the pump is ready to connect to the piping.
Rotate the shaft periodically (at least monthly) to keep rotat-
ing element free and bearings fully functional.
For long term storage, the pump must be placed in a vertical
position in a dry environment.
