pean IEC plug or a plug suitable for your local electrical

supply. The cable contains wires color coded as fol-

lows: green or green and yellow: ground; blue or white:

neutral; brown or black: hot.

Due to the high compression ratio, the pump may gen-

erate overpressure at the outlet. Check pressure com-

patibility with system components (e.g., exhaust pipe-

line or exhaust valve) at the outlet.

Do not permit any

uncontrolled pressurizing. Make

sure that the exhaust tubing cannot become blocked. If

there is an exhaust isolation valve, make sure that you

cannot operate the equipment with the valve closed to

avoid a

risk of bursting!

Always provide a free and pressureless exhaust outlet

to avoid damage to the pump and a risk of bursting.

Keep the electrical power cord away from heated sur-

faces.

• Provide a firm, level platform for the equipment. Check

that the system which you are going to evacuate is

mechanically stable. Check that all fittings are secure.

Ensure a stable position of the pump without any me-

chanical contact other than the pump feet.

• Comply with

maximum permissible pressures at in-

let and outlet and with

maximum permissible pres-

sure differences between inlet and outlet. See section

with overpressure at the inlet.

• Avoid overpressure of more than 17.5 psi absolute (1.2

bar absolute) in the event that gas or inert gas is con-

nected to the pump, to the gas ballast or to a venting

valve.

•

Note: Flexible elements will shrink when evacuated.

• Connect hoses gas tight at inlet and outlet of the pump.

• Ensure that no foreign objects can be drawn into the

pump.
