Maintenance
5.2
Leybold Service
Whenever you send in equipment to Leybold, indicate whether the equip-
ment is contaminated or is free of substances which could pose a health
hazard. If it is contaminated, specify exactly which substances are involved.
You must use the form we have prepared for this purpose.
A copy of the form has been reproduced at the end of these Operating
Instructions: “Declaration of Contamination for Compressors, Vacuum
Pumps and Components”. Another suitable form is available from the
Leybold homepage:
www.leybold.com under the headline “Support & Downloads”.
Attach the form to the equipment or enclose it with the equipment. Do not
place it together with the equipment inside the PE bag.
This statement detailing the type of contamination is required to satisfy legal
requirements and for the protection of our employees.
Leybold must return to the sender any equipment which is not accompa-
nied by a contamination statement.
5.3
Checking the Oil
During operation of the TRIVAC BCS the oil level must always remain bet-
ween marks (9/2) and (9/3) at the oil-level glass. The amount of oil must be
checked and topped up as required.
Fill in oil only after the pump has been switched off.
Pumps which have not directly been delivered from Leybold, e.g. in sys-
tems, may have been filled with oils different from N 62 or HE-200. In this
case a refill with N 62 may cause problems. Therefore check before the refill
the kind of oil in the pump and fill in only suitable oil or change the oil.
When operating the TRIVAC BCS in connection with the exhaust filter with
lubricant return (ARS 16-25) the checking intervals are extended.
When using the oil float switch (LSS) remote monitoring of the lubricant is
possible.
N 62 or HE 200 Oil
The ageing process for the standard operating fluid N 62 resp. HE 200 (see
Chapter 1.2) will depend very much on the area of application for the pump.
a) Visual check
Normally the oil is clear and transparent. If the oil darkens, it should be
changed.
b) Chemical check
The neutralisation number of N 62 oil is determined according to DIN
51558. If it exceeds 2, the oil should be changed.
