WARNING: Unexpected Startup Hazard
Disconnect and lockout power before
servicing. Failure to follow these instructions could
result in serious personal injury or death, or
property damage.
CAUTION: Extreme Temperature Hazard
Allow pump temperatures to reach
acceptable levels before proceeding. Open drain
valve. Do not proceed until liquid stops coming out
of drain valve. If liquid does not stop flowing from
drain valve, isolation valves are not sealing and
should be repaired before proceeding. After liquid
stops flowing from drain valve, leave drain valve
open and continue. Remove the drain plug located
on the bottom of the pump housing. Do not
reinstall plug or close drain valve until reassembly
is completed. Failure to follow these instructions
could result in property damage and/or moderate
personal injury.
(See exploded view on page 59.)
