MAINTENANCE
z Wear the appropriate safety-clothing when you come into contact with contaminated components. Dismantle
and clean contaminated components inside a fumecupboard.
z Tak e c ar e t o p ro t ec t t he s e al i ng - f a c es f r o m d a m a ge .
z 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 your 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. The maintenance operations you can carry 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 your process. Adjust the frequency of maintenance operations according to your experience.
When you maintain 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 your nitrogen
and cooling-water supplies comply with the data given in Section 2.1 and that they 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 you will transport or store it in conditions
where the cooling-water could freeze. If you do 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 your skin or eyes. Do
not inhale vapours from these substances. Fit blanking caps to the inlet and outlet flanges when
you move the exhaustpipe, elbow or check-valve around your 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.
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.
