Risk of electric shock.
To reduce risk of
electric shock, always disconnect
pump from power source before
handling. Lock out power & tag.
In the event the
retaining screws have
been pulled out of the housing,
DO NOT replace them. Use of any
other screw may short out the stator
windings, creating a risk of electrical shock.
The addition of
petroleum based uids
or certain chemical additives to the system
voids the warranty.
Pumps build up heat
and pressure during
operation. Allow time
for pumps to cool
before handling or
servicing.
Receiving Inspection
Upon receiving the pump, it should be
inspected for damage or shortages. If
damage has occurred, le a claim
immediately with the company that delivered
the pump. Care should be taken to ensure
the pump is NOT dropped or mishandled,
dropping will damage the pump. If the
manual is removed from the packaging, do
not lose or misplace.
