Packed valve handling precautions
• Open the valve stem all the way out ; do not try to
open it beyond the stopper.
• Securely tighten the valve stem cap in torque as
follows:
Gas side (12.7 mm (diam.))
Gas side (9.52 mm (diam.))
Liquid side (6.35 mm (diam.))
Service port
Hexagonal wrench is required.
<For RAV-SM800AT-E model>
• As shown in the figure, be sure to use a double
spanner to loosen or tighten the flare nut of the valve
at gas side. If using a single spanner, the nut cannot
be tightened with necessary tightening torque.
On the contrary, use a single spanner to loosen or
tighten the flare nut of the valve at liquid side.
