1.1 instructions for safe use

No installation of this equipment should take place
unless this document has been studied and under-
stood. Handling, transportation and installation of
this equipment should only be undertaken by trained personnel
with proper use of lifting equipment. See later diagrams for lift-
ing advice. Refer to the pump nameplate for pump speed, pres-
sure and temperature limitations. The limits stated must not be
exceeded without written permission from Armstrong .
1. 2 temper ature
Where under normal operating conditions the limit of
68°c/155°f (restricted zone) for normal touch, or 80°c/176°f
(unrestricted zone) for unintentional touch, may be experi-
enced, 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 100°c/212°f and not
withstanding pump insulation techniques appropriate mea-
sures must be taken to minimize risk for operating personnel.
