Figure 13 Dp Clean Assembly For The Pump Only Systems - Edwards GXS Series Instruction Manual

The pneumatic regulator is pre-set to 50 ± 5 psig in the factory and does not need to be
adjusted. The pneumatic regulator is shown in
only systems, item 5 for the pump‑only systems. For pump and booster combination
systems, the regulator is contained within the pump enclosure.
To use an inert gas in place of atmospheric air as the DP clean purge gas, remove the air
filter and in its place connect up the inert gas supply. For pump and booster
combinations, the air filter is on the rear pump panel (refer to
connectors on the rear of the pump (system with rear exhaust and castors/levelling feet
fitted), item 12). For pump‑only systems, refer to
only systems, item 1. Refer to
for information about fittings and typical purge gas flows.
A solvent suction pipe is provided with the pump. When only performing a high flow
purge procedure, the solvent suction pipe will not be needed. When performing a
solvent flush, fit the solvent suction pipe only when ready to perform the DP clean
procedure. For pump and booster combinations, the solvent flush fluid connection is on
the rear pump panel (refer to
(system with rear exhaust and castors/levelling feet
systems, refer to
A PDT is required to operate the DP clean high flow purge and solvent flush.
