TYPICAL SYSTEM-30 INSTALLATION

CAUTION

Before you attempt to use the BTU measurement system, isolate the main unit, open the bypass

free moving particles.

Installing the meter body

1. Make sure the unions are free of nicks or scratches on either end of the ow

meter body and on the process connections.

2. Spray the union faces with a silicone spray or apply a thin coat of beeswax to enhance

seating. Do not use paste thread sealant on union faces.
