Maintenance - Cornelius CH1500-CH7500 Operator's & Installation Manual

!
WARNING:
Disconnect power to the unit before servicing. Follow all lock out/tag out procedures established by the user. Verify all
power is off to the unit before performing any work.
Failure to comply could result in serious injury, death or damage to the equipment.
The chiller requires very little normal maintenance.
1. On AIR-COOLED Chillers, the condenser fins should be cleaned by blowing compressed air through the
condenser from the fan side as required to eliminate any dirt or debris that may accumulate over time. This
can severely reduce the performance of the Chiller. Cleanable air filters are available as an option. Contact
the factory for information.
2. On AIR-COOLED Chillers the condenser fan motor should be lubricated every 6-months with a few drops
of SAE10 oil.
3. The pump motor should be lubricated with thirty drops of SAE20 oil once a year.
4. The circulation system should be drained and flushed periodically to avoid build-up and possible restriction
of flow by contaminates.
5. The strainer at the Chiller inlet should be removed and cleaned monthly (field installed).
