✝ Not required for F-model pumps; use CF fittings (which must be obtained from another supplier).
★ Not required for C-model pumps; use claw clamps to bolt the pump ISO inlet-flange directly to the ISO tube
and collar assembly.
P Bolts are not available from Edwards. Bolts are not required for C-model pumps; use claw clamps to bolt
thepump ISO inlet-flange directly to the ISO tube and collar assembly. Use 4 claw clamps for ISO63, ISO100
and ISO160 flanges.
■ These inlet seals are only suitable for M-, P- and C-model pumps; use CF fittings (which must be obtained from
another supplier) for F-model pumps.
● Only required for pneumatically operated BRV valves; use 1 standard 5-port control-valve or 2 lightweight
5-port control-valves. If you use 2 lightweight 5-port control-valves, you can use the isolation position of the
BRV valve.
▲ Only required for P-model pumps, to control the high-vacuum isolation-valve.
◆ Supplied with the pump (1 off of each component).
