7.1. Initial start-up
Before switching on the vacuum pump system, check the following
points:
Prerequisites for start-up

All hoses attached properly

Fan openings not blocked

Specifications of the power supply correspond with the
data on the vacuum pump system’s type plate

Recirculating cooler or cold water connection ready on
high-performance condenser

The high-performance condenser's gas outlet is not
blocked (high-performance condenser is not pressure-
proof)

Vacuum pump system at ambient temperature

Ensure that hand terminals are properly matched up with
the appropriate vacuum pump system

If the vacuum system is ventilated through the air inlets
(Fig. 2/
17 and 18 , p. 13) no reactive, explosive, or other-
wise dangerous mixtures can form (use inert gas if nec-
essary)

When the gas ballast valve is open (blue LED lit), no re-
active, explosive, or otherwise hazardous mixtures can
form (otherwise, contact KNF Service).
