9 Before pumping condensable vapours the pump should be at operat-
ing temperature. If a gas ballast is present, then it should be opened.
The pump will attain its operating temperature approximately 30 min-
utes after having started the pump. During this warm-up phase, the
pump should be left separated from the process by a valve in the
i ntake line, for example.
10 With the pump warm from operation do not clean it from the outside
with water. There is the risk of a rotor crash due to shock cooling.
11 If condensable vapours have been pumped, the pump should before
switching off be purged for about 15 minutes with an inert gas or air
(depending on the specific application). This process should also be
run before cleaning the pump chamber.
12 For shutting down the pump let the pump operate idle for at least 30
minutes. Disconnect the pump from the mains power. Place desiccant
into the intake flange and into the discharge flange and blank off the
flanges with a piece of foil.
When storing the pump for a longer period of time, drain out the oil
first. Package the pump airtight in polyethylene foil.
13 Improper maintenance or repair work can have an influence on the
service life and the performance of the pump and will void any warran-
ty claims.
14 Maximum cooling water pressure: 6 bar. When exceeded, there is the
risk of leaks.
15 The pump must only be operated at ambient temperatures between
10 and 40 or 50 °C. The thermal radiation produced by the pump
must be removed to a sufficient extent. If for whatever reason the
pump needs to be operated at higher ambient temperatures, then
reduced maximum pressure differences apply (derating). For operation
under such conditions please consult Leybold.
16 In order to prevent the transfer of vibrations from the RUVAC to other
system components which have been connected, we recommend fit-
ting of corrugated hoses respectively compensators on the intake and
the discharge side.
17 Do not operate the RUVAC WH/WHU in connection with backing
pumps where an ultimate pressure exceeding 10 mbar is specified.
This will prevent excessively high temperatures when the RUVAC is
running idle.
18 The ingress of particles and liquids must be avoided under all circum-
stances.
Pressures stated in bar or mbar are absolute pressures, except something
else is expressly mentioned (for example, bar(g))
