Setting Up And Installing The Equipment - vacuubrand MZ 2C NT+2AK Instructions For Use Manual

Setting up and installing the equipment

➨ Equipment must be connected only to a suitable elec-
trical supply and a suitable ground point. As such,
the plug must be plugged into an outlet that is properly
grounded. Failure to connect the motor to ground may
result in deadly electrical shock.
The supply cable may be fitted with a molded Europe-
an 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.
+ Check the overpressure safety relief device at the ex-
haust waste vapor condenser at appropriate intervals.
+ Keep the electrical power cord away from heated sur-
faces.
+ Keep the electrical power cord away from hot surfaces.
• 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
"Technical data", pg. 26. Do not operate the pump
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 connect-
ed to the pump, to the gas ballast or to a venting valve.
