MAINTENANCE SCHEDULE
Air conditioning
IMPORTANT
The air conditioning system must be run for a minimum of
ve minutes each week regardless of the season to
lubricate the system and prevent damage to the seals.
Ensure a qualied technician is employed for any
repairs required.
To ensure dependable ecient operation, all air conditioning units
require a certain amount of Preventative Maintenance to be carried
out at regular intervals between services.
These regular inspections will ensure that the unit is always
operating at peak eciency and will provide early warning of
potential problems, which if left unattended, may incur costly
machine down-time.
It is strongly recommended that an annual service programme be
implemented. This full unit service should be carried out once a
year, generally just prior to the beginning of the warmer season.

system, as well as checking of component settings.
