Emerson B302 Installation, Operation And Maintenance Instructions

YARWAY B302, B303, B318 AND B320 BIMETALLIC STEAM TRAPS AND AIR ELIMINATORS
SUMMARY OF INSTALLATION, OPERATION AND MAINTENANCE INSTRUCTIONS
Before installation, these instructions must be carefully read and understood.
INSTALLATION
• Before installation, remove plastic covers
placed on flanges or connection ends. The
equipment has an arrow for Inlet/Outlet
designations. Be sure that it is installed in the
appropriate direction.
• Install the steam trap at a point where the
condensate tends to accumulate. A strainer
can be installed upstream of the trap for
additional protection.
MAINTENANCE
• We recommend that the steam traps are
serviced as necessary. Steam traps should be
checked periodically (at least yearly), to verify
that they are operating correctly and to clean
the internal parts and strainer screen.
• When reassembling, make sure that all
gasket faces are clean and always use a new
gasket. Tighten cover bolts uniformly in a
diagonal sequence.
WARNING
At startup, the presence of small particles in the
water (dirt, scale, weld splatters, etc.) may cause
an imperfect closure of the seat. If this occurs,
clean the equipment accordingly.
Do not touch the equipment without appropriate
protection during operation because it may
conduct heat if the used fluid is at high
temperature.
Before starting maintenance, be sure that the
equipment is not pressurized or hot.
The equipment must be used within its pressure
and temperature limits, otherwise it might fail
(refer to nameplate or documentation).
Do not remove the nameplate attached to the
equipment. Serial number and other useful
information are stamped on it.
