Operation
59GA02411_002_C0 - 10/2016 - © Leybold
The pump may only be switched on after it has been completely assem-
bled and with the fan’s housing closed.
Operation without intake and discharge lines or silencer is not allowed.
In the discharge line no pressure > p
ex
= p
amb
+ 200 mbar must be allowed
to build up even if the discharged gases need to be collected or contained.
Make sure that the gas flow at the discharge is not blocked or restricted in
any way.
Depending on the pump version switch on
■
cooling water
■
power supply for the SP-Guard
■
gas ballast
■
purge gas
Then switch on the pump.
Start the pump only six times per hour at the most so as to avoid over-
loading the motor.
Between pumping chamber and gear, the pump has been equipped with
non-contacting seals. These seals have been provided with a vent at the bot-
tom side of the pump. Small quantities of gear oil can escape from this vent.
This will in no way influence safe operation of the pump.
Please note safety information 0.4.7.
The motor casing is vented through a channel which opens next to the motor
junction box. From this vent small quantities of gear oil can escape. This will
not have a negative influence on safe operation of the pump.
For water cooled pumps only
Thermostat settings 4 and 5 must not be set up since damage may occur
due to inadequate cooling.
At water temperatures exceeding 25° C the thermostat will no longer be able
to maintain a constant oil temperature. The air cooling share will then
increase.
