z Purge the vacuum system and the pump with dry nitrogen and disconnect the pump from the vacuum system.
z Shut down the pump as described in Section 4.
z Disconnect the pump from the electrical supply.
z Disassemble, clean and reassemble the pump. If the pump is to be stored for long periods, loosen the drive
belts and change the oil.
z Place and secure protective covers on the inlet and exhaust ports.
z Store the pump in cool, dry conditions until it is required for use. When required, prepare and install the
pump as described in Section 3. If the pump will be subjected to temperatures below freezing, drain or add
anti-freeze to the water jacket. If the pump will be stored for more than a year, the pump must be cleaned
and overhauled before re-installation.
