Emerson B302 Manuel

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.
