3 Installation
CAUTION
Edwards will accept no liability or warranty claims if your installation includes any modifications or additions to
the pump without the prior written approval of Edwards, or if the pump is incorrectly installed.
3.1 Installation safety

A suitably trained and supervised technician must install your HV8000 pump.

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.

Consult Edwards publication P400-40-100 (Vacuum pump and vacuum system safety - chemical and industrial
systems) before you install and use the HV8000 pump.

Vent and purge the pumping system before you start installation work.

Ensure that debris does not get into the HV8000 pump or the system pipelines when you install it.

Disconnect the other components in the pumping system from the electrical supply so that they cannot be
operated accidentally.

Do not reuse O-rings and Co-Seals.

On pumps with a motor, ensure that the cooling-air flow through the pump-motor cooling-fan cannot be
obstructed.

Ensure that all electrical cables, purge gas pipelines and cooling-water pipelines are safely positioned,
secured and routed, so that they do not present a trip hazard.

Provide adequate access to all pump servicing points and oil-level sight-glasses.

Check that all of the required components and tools are available and of the correct type before you start to
install the pump.

Leak-test the system after installation work is complete and seal any leaks found to prevent leakage of
hazardous substances out of the system and leakage of air into the system.
WARNING
Obey the safety instructions listed below and take note of appropriate precautions when you
install the pump. If you do not, you can cause injury to people and damage to equipment.
