be safe and without risk to health and safety when properly
installed, operated and maintained. The instructions
following must be strictly adhered to. If clarification is
needed on any point please contact Armstrong quoting the
equipment serial number.

instructions for safe use
No installation of this equipment should take place unless
this document has been studied and understood. handling,
transportation and installation of this equipment should only
undertaken by trained personnel with proper use of lifting
equipment. See later diagrams for lifting advice. Refer to the
pump nameplate for pump speed, pressure and temperature
limitations. The limits stated must not be exceeded without
written permission from Armstrong.
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 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 100°c/212°f and not withstanding pump insulation
techniques appropriate measures must be taken to minimize
risk for operating personnel.

stor age
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. Internal rusting can be prevented by
removing the plugs at the top and bottom of the casing and
drain or air blow out all water to prevent rust buildup or the
possibility of freezing. Be sure to reinstall the plugs when the
unit is made operational. Rust proofing or packing the casing
with moisture absorbing material and covering the flanges is
acceptable. When returning to service be sure to remove the
drying agent from the pump.
uncr ating
Armstrong End Suction pumps are thoroughly inspected
before shipment to assure they meet with your order require-
ments. After removing the pump from the crate, make sure
the equipment is in good order and that all components are
received as called for on the packing list. Any shortages or
damage should be reported immediately. Use extreme care
in handling the unit, placing slings and hooks carefully so that
stress will not be imposed on the pump. Never place cable
slings around the pump shaft. The eye bolts or lifting lugs on
the motor are intended for lifting only the motor and not the
complete unit.
handling
Use slings as shown in the diagram to lift the set. Do not use
the motor eyebolts to lift the pump set. See the delivery note
for the weight of the set.
