Additional Installation Requirements “X”
In addition to the installation information provided in the main Operating
Instructions, the following needs to be ensured:
The pump must exclusively be filled and operated with the oil LVO 100 or
LVO 210 as the operating agent.
The use of other oils can result in higher surface temperatures thereby
causing severe damage to the pump.
The pump must be installed such that the oil level sight glass can be read off
easily and can not be damaged.
Install the pump such that only minimal quantities of dust can deposit them-
selves on the surfaces. In those cases where dust deposits form, measures
need to be introduced which ensure that these are removed on a regular
basis.
The permissible ambient temperature is between 12 °C and 40 °C.
The maximum discharge pressure (= forevacuum pressure) must not exceed
p
const
when no temperature monitoring has been installed for the RUVAC WA/
WAU. Here the following applies to the inlet pressure: p
a
= p
const
/ k
th
.
If the pump (outside) has been certified for operation in areas with explosive
atmospheres, the special information contained in the European standards
EN 60079-14 «Electrical apparatus for explosive gas atmospheres Part - 14»
and EN 60079-17 «Electrical apparatus for explosive gas atmospheres - Part
17» needs to be complied with.
The pumps are not suited for applications in which abrasive and cohesive
substances or condensable vapors are produced which may form sticky,
tough, layer-forming deposits. After having switched off the Roots pump,
its pistons are subjected to post-heating and for this reason it is essential
to maintain a cooling down time of 30 minutes. Thereafter the pump may
be switched on again.
