Wear the appropriate safety-clothing when you come into contact with contaminated components. Dismantle
and clean contaminated components inside a fume-cupboard.
Re-check the pump rotation direction if the electrical supply has been disconnected.
O-ring replacement intervals vary depending on your application.
Dispose of components, grease and oil safely.
Take care to protect sealing-faces from damage.
Do not touch or inhale the thermal breakdown products of fluorinated materials which may be present if the iH
system has been overheated to 260 °C and above. These breakdown products are very dangerous. Fluorinated
materials in the iH system may include oils, greases and seals. The iH 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).

Relocate the system for maintenance

The substances that accumulate in the exhaust-pipe, elbow and check-valve 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.
You must use suitable lifting equipment to move the system. It is too heavy to lift by hand.
