3 INSTALLATION
3.1 Safety
WARNING
Obey the safety instructions given below and take note of appropriate
precautions. If you do not, you can cause injury to people and damage to
equipment.
•
Only BOC Edwards engineers may install the iH pump series. Users can be trained by BOC
Edwards to conduct the tasks described in this manual, contact your local service centre or
BOC Edwards for more information.
•
Ensure that the installation technician is familiar with the safety procedures which relate to the
products pumped. Wear the appropriate safety-clothing when you come into contact with
contaminated components. Dismantle and clean contaminated components inside a
fume-cupboard.
•
Do not remove the temporary cover or blanking plate from the iH system inlet until you are
ready to connect the iH system to your vacuum system. Do not operate the iH system unless
the inlet blanking plate is fitted or the iH system is connected to your vacuum system.
• Do not remove the temporary cover or blanking plate from the iH system exhaust until you are
ready to connect the iH system to your exhaust-extraction system. Do not operate the iH
system unless the exhaust is connected to your exhaust-extraction system.
•
Vent and purge the process system (if the iH system is to replace an existing pumping system)
with nitrogen for 15 minutes before you start installation work.
•
Disconnect the other components in the process system from the electrical supply so that they
cannot be operated accidentally.
•
Do not reuse any 'O' ring or 'O' ring assembly and do not allow debris to get into the iH system
during installation.
•
Wipe up any water or oil spilt during installation to avoid possible risk of slips.
•
Route and secure cables, hoses and pipe-work during installation to avoid possible risk of
trips.
•
Obey all national and local rules and safety regulations when you install the iH system.
•
Consult BOC Edwards publication P300-20-000 (Vacuum Pump and Vacuum System Safety)
before you pump hazardous materials. This publication is available on request: contact your
supplier or BOC Edwards.
