Maintenance
Wait for at least four minutes after you have switched off the electrical supply before you touch any
electrical component on the dry pumping system.
Route and secure cables, hoses and pipelines during maintenance to avoid possible risk of trips or
entrapment.
Ensure that any oil or water collected in the secondary containment drip tray is removed before moving the
system.
The enclosure panels should only be removed with the use of a special tool, when the system has been
switched off and allowed to cool sufficiently.
Wear the appropriate safety-clothing when you come into contact with contaminated components. 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
iXL120 system has been overheated to 260 °C and above. These breakdown products are very dangerous.
Fluorinated materials in the iXL120 system may include oils, greases and seals. The iXL120 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.
5.2
Relocate the system for maintenance
CAUTION
Drain the cooling-water from the iXL120 system as stated in
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 iXL120 system
and damage the pump(s) and/or the cooling-water pipelines.
WARNING
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 exhaust-pipe, 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.
WARNING
You must use suitable lifting equipment to move the system. It is too heavy to lift by hand.
WARNING
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.
