Maintenance
General requirements
The units have been designed to operate continuously provided they are regularly maintained and
operated within the limitations given in this guide. Each unit must be included in a routine schedule
of daily maintenance checks by the operator or customer, backed up by regular service inspection
and maintenance visits by a suitably qualified service engineer.
It is entirely the responsibility of the owner to provide these regular maintenance requirements or
enter into a maintenance agreement with a Johnson Controls service organization to protect the
operation of the unit. If damage or a system failure occurs due to incorrect maintenance during the
warranty period, Johnson Controls is not liable for costs incurred to return the unit to satisfactory
condition.
Note: This maintenance section applies to the basic unit only and may, on individual
contracts, be supplemented by additional requirements to cover any modifications or ancillary
equipment as applicable.
CAUTION
You must carefully read General chiller information and safety and Unit operation before attempting
any maintenance operations on the unit.
Daily maintenance
About this task:
The operator or customer must carry out the following maintenance checks daily. Note that the
units are not generally user serviceable. Do not attempt to rectify faults or problems found during
daily checks unless competent and equipped to do so. If in any doubt, contact your local Johnson
Controls Service Centre.
Refrigerant leaks: Visually check the cooler, air-cooled condensers, compressors, and pipework for
damage and gas leaks.
Condenser fan motors: The fan motors are permanently lubricated and require no maintenance.
Airflow obstructions: Check the air-cooled condenser coil intakes and adjacent areas are clear of
foreign materials or obstructions for example paper or leaves.
CAUTION
See Technical data for the inverter compressor oil information.
