5. Fit the external EMS link plug (supplied) to the EMS connection on the rear of the system
the plug is not fitted, the water system cannot be purged effectively.
6. Monitor the drain hose outlet.
7. Connect the system to a suitable mains electrical supply. The control system will now open each temperature
control valve, purging the cooling water from all flow paths. After two minutes, remove the electrical supply.
Wait for 10 seconds and then re-connect the electrical supply and repeat the entire process. Continue repeating
until no further cooling water is purged from the system.
8. The cooling water drain procedure is now complete. Disconnect the air supply, electrical supply and the drain
hoses. Dispose of the drained cooling water appropriately.

General maintenance

Do not use cleaning materials based on strong alkalis, aggressive or chlorinated solvents. Do not use cleaning
materials containing abrasives.
The pumping system is given a charge of oil before leaving the factory. There is no requirement to check and adjust
the oil level between major overhauls.
Edwards recommends that carrying out a monthly visual inspection of the system in situ. Check that the cables, hoses
and pipelines bringing services to the pump are in good condition and ensure that all connections are secure.
The following maintenance can also be carried out on the system. Contact Edwards for details and training.
Inspect the connections, pipelines, cables and fittings inside the pump enclosure, refer to

Inspect and clean exhaust pipe, elbow, and check valve.

Note: The system is supplied with either a trapped O-ring or a metal seal for the exhaust connection, depending
on pump type and anticipated exhaust temperatures. Ensure that seals are always replaced with the same
type.
5.5

Inspect the connections, pipelines, cables and fittings

Electrical, nitrogen and water supplies are all potentially hazardous energy sources. Before
carrying out any maintenance, the supply of these sources should be locked and tagged out.
If the system is not relocated for maintenance, ensure all supplies are locked out and tagged out before starting the
following procedure.
1. Remove the enclosure side and top panels.
2. Check that all the connections are secure; tighten any loose connections. Inspect all cables, pipelines, hoses and
connections and check that they are not corroded or damaged and do not leak; repair or replace any pipelines,
hoses and connections that are corroded or damaged, or which leak.
3. Refit the enclosure side and top panels.
5.6

Gas module configuration

The gas module has no user-configurable options but it is recommended to periodically check the nitrogen flow on
an N variant pump and adjust if necessary. Contact Edwards for process specific requirements.
