Edwards EDS 300

7. Installaon
WARNING: RISK OF CUTTING AND CRUSHING
Risk of cung and cung o by contact with moving parts such as couplings, shas and
rotors. Risk of cung and crushing when reaching into open anges or covers. Do not
operate the vacuum pump with open anges or covers. When installing, rst
mechanically connect the inlets and outlets, close the covers of rotang parts and then
make the electrical connecons. Disconnect the vacuum pump from the power supply
before servicing. Only use trained service personnel.
WARNING: EJECTION OF PARTS
Ejecon of parts through bursng of vacuum system due to excessive pressure caused by
incorrect direcon of rotaon. Pressure build-up in the vacuum system or in vacuum
chambers. Check the direcon of rotaon of the vacuum pumps before each start-up,
aer each motor change and aer each electrical connecon change.
Ejecon of parts through bursng of vacuum system due to excessive pressure, caused by
faulty funcon at the gas inlet into the vacuum system. Pressure build-up in the vacuum
system or inlet lines. Check correct connecon of inlet and outlet anges before
commissioning. The inlet pressure at the sucon port of the vacuum system must not
exceed atmospheric pressure. If seal gas or gas-ballast from pressure vessels is used,
secure the supply in such a way that no overpressure can occur in the vacuum system in
the event of a fault or power interrupon.
WARNING: RISK OF GAS LEAKAGE
The atmospheric sha seal between the gearbox and atmosphere is a PTFE dynamic seal,
which may, under wear-out condions, lead to small leakage of gas. Ensure that purge
gas is supplied connuously to the main pump sha seals to prevent process gas entering
the gearbox which could otherwise leak from the atmospheric sha seal. Leakage of
purge gas to atmosphere should also be considered; ensure the pump is in a well
venlated area.
Only competent persons may install this EDS pump.
▪
Ensure that you comply with all local and naonal safety requirements when you install
the pump.
▪
Do not operate the pump system unless the inlet and outlet are connected to your
piping system.
▪
Disconnect the other components in the pumping system from the electrical supply so
that they cannot be operated accidentally.
▪
Electrical, purge gas and water supplies are all potenally hazardous energy sources.
Before carrying out any maintenance the supply of these sources should be locked and
tagged out.
▪
Ensure that the cooling-air ow through the pump-motor cooling-fan cannot be
obstructed.
▪
Ensure that all electrical cables, purge gas pipelines and cooling-water pipelines are
safely posioned, secured and routed, so that they do not present a trip hazard.
