Edwards EXS Series User Manual

WARNING:
We r
ecommend the use of water and diluted Locte® 7840 or Locte® Natural Blue®
when performing a solvent ush procedure. It is your responsibility to assess
whether the Locte® 7840/Natural Blue® is compable with the applicaon. For
more informaon refer to the Locte® MSDS and technical datasheet. The
manufacturer states that the Locte® 7840 and Locte® Natural Blue® are not
recommended for use in pure oxygen and/or oxygen rich systems and should not be
selected as a sealant for chlorine or other strong oxidizing materials.
For queries about the solvent compability, contact our applicaons specialists.
WARNING:
Hot st
eam and liquid will exit the pump during the solvent ush procedure. Ensure
that the exhaust is piped away safely and solvents are disposed of in accordance with
the local and naonal safety and environmental requirements.
CAUTION:
If an inert gas is used in place of a
tmospheric air for the DP clean purge gas, ensure it
is regulated to atmospheric pressure otherwise the DP clean process may not work
properly and may cause damage to the pump.
The high ow pur
ge and solvent ush procedures are performed by a single assembly
which is supplied as an oponal kit. The actuang valve is operated pneumacally.
Ensure that the pneumac gas supply meets the specicaon given in DP clean high ow
purge/solvent ush (opon) on page 23.
Use a 3/8 inch compression ng (not supplied) to connect the pneumac supply to the
dry pumping system. For the pump‑only systems, refer to Figure: DP clean assembly for
the pump only systems.
The pneumac regulator is pre-set to 50 ± 5 psig in the factory and does not need to be
adjusted. The pneumac regulator is shown in Figure: DP clean assembly for the pump
only systems, for the pump‑only systems.
To use an inert gas in place of atmospheric air as the DP clean purge gas, remove the air
lter and in its place connect up the inert gas supply. For pump‑only systems, refer to
Figure: DP clean assembly for the pump only systems. Refer to DP clean high ow purge/
solvent ush (opon) on page 23 for informaon about ngs and typical purge gas
ows.
When only performing a high ow purge procedure, a solvent sucon pipe will not be
needed. When performing a solvent ush, t a solvent sucon pipe only when ready to
perform the DP clean procedure. For pump‑only systems, refer to Figure: DP clean
assembly for the pump only systems.
