SCHEDULE:
• Initially, every 2-3 days after start-up until
system is clean.
• Every 6 months thereafter.
PROCEDURE:
• To prevent serious burns, the internal pressure of the trap must be 0 psi (0 bar)
before servicing.
• To prevent serious personal injury from steam pipe blow down, connect a temporary
pipe between the steam pipe opening and a drain, or stand at least 100 ft. (30m) from
the front of the pipe opening.
Failure to follow this caution will cause personal injury.
! CAUTION
1.Inspect joints for leaks. Stop all leaks by tightening
bolts and replacing gaskets, if necessary.
2.Clean strainers by opening the blow down valve and
allowing full steam pressure to flow out for (2) two
minutes. Then, close the valve.
3.Test traps by following the “Troubleshooting”
procedure.
