Maintenance
Wear the appropriate safety clothing if contact with contaminated components is anticipated. Dismantle and
clean contaminated components inside a fume cupboard.
Take care to protect the sealing-faces from damage.
Do not touch or inhale the thermal breakdown products of fluorinated materials which may be present if the
iGX system has been overheated to 260 °C and above. These breakdown products are very dangerous.
Fluorinated materials in the iGX system may include oils, greases and seals. The iGX system may have
overheated if it was misused, if it malfunctioned or if it was in a fire. Edwards Material Safety Data Sheets
for fluorinated materials used in the pump are available on request: contact the supplier or Edwards (refer
to the address page at the rear of this manual for contact details).
The iGX system requires little user maintenance. Safety sensors fitted to the iGX system do not require routine
maintenance. Customer maintenance operations that can be carried out are described in the following sections, any
other maintenance must be carried out by Edwards service centres (refer to Section 7). The frequency of
maintenance operations depends on the process. Adjust the frequency of maintenance operations according to
experience.
When maintaining the iGX system, use Edwards maintenance and service kits. These contain all of the necessary seals
and other components necessary to complete maintenance operations successfully. Ensure that the nitrogen and
cooling water supplies comply with the data given in Section 2.1 and are connected in parallel. Contact Edwards or
refer to the Edwards website.
5.2 Relocate the system for maintenance
Drain the cooling water from the iGX system as stated in Section 5.3, if transporting or storing it in conditions
where the cooling water could freeze. If not, cooling water may freeze in the iGX system and damage the
pump(s) and/or the cooling water pipelines.
The substances that accumulate in the exhaust-pipe, elbow and check-valve (supplied separately)
can be dangerous. Do not allow these substances to come into contact with skin or eyes. Do not
inhale vapours from these substances. Fit blanking caps to the inlet and outlet flanges when
moving the exhaust pipe, elbow or check valve around the workplace.
The majority of synthetic oils/grease can cause inflammation of the skin (dermatitis). Safety
precautions must be taken to prevent prolonged skin contact with these substances. Use of
suitable protective gloves and clothing along with a respirator is recommended if contact with the
substance is anticipated.
System process gases and residue can be highly toxic. Take all necessary precautions when
handling components that have, or could have, come into contact with them, including O-rings,
lubricants and all exhaust accessories.
Use suitable lifting equipment to move the system. It is too heavy to lift by hand.
Do not exceed the topple angle of 10° when moving the pump. Wheel the system on its castors to
move it into its operating position. The system should only be wheeled short distances over flat
surfaces. If the floor surface is uneven or has obstacles the system should be lifted with suitable
lifting equipment.
