Vacuubrand PC 3001 TE VARIO PRO Instructions For Use Manual - Uncontrolled Pressurizing

 page 15 of 121

  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

. Make 

sure that the exhaust pipeline 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! 

+

 Maximum permissible pressure at the pressure trans-

ducer: 21.8 psi (1.5 bar) absolute.

+

 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 

„Technical data“, pg. 27. 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 inert gas is connected 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.
