Set-up of pump before first operation

Pump is supplied without oil charge; before initial operation, it is mandatory to fill the pump with
the recommended oil charge.
Filling of oil
Pump must be turned off for filling the oil and level control.
Pump is supplied with a mineral oil bottle but without oil charge inside the vacuum pump; before
initial operation, it is mandatory to fill the pump with the oil up to the indicated oil level in the oil
level sight glass. Only use ROTHENBERGER oil; different lubricants reduce performance and
may cause irreversible damage to the pump. Warranty is void if other oil has been used.
For fill-up proceed as follows:
 Unscrew charging plug (placed on upper part of pump)
 Slowly add the oil until middle of sight glass has been reached (indicated by MAX MIN line)
 Screw-on the plug again
To avoid excessive filling, it is suggested to only add the oil with a graduated recipient; in that
way it is easy to check the added volume. In case of excessive filling, it is necessary to com-
pletely empty the pump and repeat the oil filling procedure.
WARNING: Do not pollute the environment by spilling oil; the lubricant oil is a special
waste and must be disposed of according to relevant local law / guidelines in force.
Connection for evacuation
Shorter hose length or wider ID, as well as straight path, reduce the evacuation time as the
pump will reach the desired vacuum more quickly. To prevent backflow of lubricant from the
pump into the evacuated system in case of unexpected power failure, a solenoid non-return
valve is provided at the suction connection.
General precautions
The pump temperature is not expected to rise to a very high level during operation; however it is
advisable to locate the unit in such a way that no contact can be made, as it may cause burns.
When using the pump with other equipment, it must be ensured that the pump is fixed properly
and safe to use for the operator.
The vacuum pump is air cooled by a built-in fan; only use it where the air can freely circulate and
keep it away from walls or obstacles no less than 2" (5 cm). Do not cover the pump during oper-
ation.
