Maintenance; Maintenance And Inspections Schedule - Harsco Industrial SC-2000 Installation & Owner's Manual

Lockout/tagout procedure must be
employed when servicing this unit.
Failure to do so could result in
electrocution, injury, or death.
Label all wires prior to
disconnection when servicing
controls. Wiring errors can cause
improper and dangerous operation.
Use care when reassembling main
gas line and ensure all connections
are tight. Use a leak detector to
check for leaks before and after
servicing any component of the
gas piping. Failure to do so could
result in injury or death.
Use care when servicing boiler to
prevent the accumulation of gas in
or around the combustion
chamber. Pockets of accumulated
gas are subject to combustion
and/or explosion which could result
in injury or death.
Determine the cause of any lockout
or errors before resetting the boiler.
If able to determine cause of
lockout, then appropriate corrective
action should be taken. If unable
to determine cause of the problem,
call a qualified service technician.
Verify proper operation after
servicing.
Check daily to be sure that the
boiler area is free and clear of any
combustible materials, including
flammable vapors and liquids.
