MAINTENANCE
Always turn off power supply before servicing.
For each 25 hours of operation:
Check oil level in vacuum pump as follows:
Let the EVACUATION process run approximately 3 minutes where high and low pressure hoses are
closed and disconnected. Turn off the power supply.
1. Remove grid (four screws) from lower part of station.
2. When the oil level falls below the middle of sight glass 30, remove cap 29 and replenish the oil
until the correct level is reached.
3. If the vacuum pump is overfilled (sight glass full) oil must be drained via plug 31 until the correct
level is reached.
4. Replace grid.
For each 75 hours of operation:
Clean the cooling surfaces of the condenser as follows:
1. Remove grid (four screws) from lower part of station.
2. Clean condenser with compressed air and perhaps a soft brush. Be careful not to bend the fins
since this will reduce condenser capacity.
3. Replace grid.
