3.3 Locate the pump
3.3.1 General requirements
You must operate the pump with its inlet-flange horizontal and at the top. The pump can be free-standing,
or you can bolt the pump-inlet directly to your vacuum system:
• If the pump will be free-standing, you must support the pump and/or the backing pipeline to stabilize
the pump.
• If the pump will be connected directly to your vacuum system, ensure that your vacuum system can
support the mass of the pump (see Section 2.3).
Locate the pump at a practical distance from suitable electrical and cooling-water supplies, and so that
you can access the fluid drain-plug and fill the pump (see Section 3.9).
If you have an air-cooled EO2K pump, ensure that the cooling-air inlet to the fan is not blocked or
obstructed so that air flow through the fan is restricted, and ensure that the temperature of the cooling-
air does not exceed the maximum specified in Section 2.6), otherwise the cooling-fail thermal snap-
switch (if fitted) will operate to shut down the pump.
3.3.2 Installation on a vacuum system
Note: If you want to fill the pump with fluid through the inlet flange (as described in Section 3.9.3), fill the pump
before you install it on your vacuum system.
1. Inspect the pump inlet, the pump outlet, and the ‘O’ ring grooves on the pump and on your vacuum
system; refinish if necessary: refer to Section 3.4.2.
2. Place the inlet seal on the pump inlet. (The inlet seal is either a Co-Seal or a trapped ‘O’ ring: see
Section 3.4.2).
WARNING
If the pump is not directly flange mounted to the vacuum system, you must provide
additional support to ensure that the pump is stable and supported. If you do not and the
pump topples or falls, there is a risk of injury to people or damage to the pump or other
equipment.
WARNING
If necessary, fit suitable guards to prevent accidental contact with the pump. During
operation, surfaces of the pump are very hot and can cause injury to people.
CAUTION
Avoid contact between the pump and combustible materials, plastic materials and electrical cables.
Surfaces of the pump are very hot and can cause damage to equipment.
WARNING
Use suitable lifting equipment or ensure that two or more people lift an EO6K pump. If
you do not, you can cause injury to people or damage the pump or other equipment.
Refer to Section 2.3 for the mass of the EO6K pump
