18. MAINTENANCE AND SERVICING
1. Normal maintenance of the appliances is generally limited to replacing filters.
2. The filters must be changed at regular intervals. The frequency is dependent on the specific
application conditions. Certain installations, for example in hotels where there large amounts of
fluff due to the frequent bedding changes and the presence of fitted carpets, require more frequent
filter changes. It is recommended that the filters are checked every 60 days during the first year of
operation in order to determine the frequency required. If it is not possible to see light through the
filter when it is held up to the sun or in front of a strong light, the filter must be replaced. A more
rigorous standard of cleanliness may be required.
3. The condensates tray must be checked annually and cleaned and rinsed if necessary.
4. On commissioning, a record of voltages, current draw and temperature variances should be made.
Thereafter, on an annual basis further measurements can be compared to these initial values and will
be useful for giving an overall indication for the equipment’s general condition.
5. The activation of the unit’s safety protection devices is usually caused by air or water problems.
These forced stoppages are a normal protection measure. Ensure that there is no dirt or debris in the
air or water circuits. Check the water and air temperatures and flows (clogged filters).
CAUTION
BEFORE CARRYING OUT ANY OPERATION ON THE EQUIPMENT, CHECK
THAT THE ELECTRICAL POWER SUPPLY IS SWITCHED OFF AND THAT IT
CANNOT BE SWITCHED ON INADVERTENTLY.
18.1. FAN DRIVE SYSTEMS
Fan shaft and motor bearings are of permanently lubricated, sealed type and require no regular maintenance
other than a check on their general condition. The fan belt tension should be checked regularly and belt
surfaces inspected for cracks or excessive wear.
For a quick check, make sure that the small
rope touch each end of the pulleys as shown
on drawing opposite.

18.2. FAULT FINDING
18.2.1. NEITHER THE FAN NOR THE COMPRESSOR OPERATE
1. The system is in alarm mode when the mains power supply is switched on. Check the points
mentioned in the "Alarm codes" chart for diagnosis.
2. Check the wiring of the remote control.
3. Check that the appliance is properly set in COOL, HEAT or FAN mode.
4. Check the condition of the fuse or the mains power supply. Check the compressor and fan wiring.
5. Check for any loose or broken wiring and tighten or replace as required.
6. The mains supply voltage is too low. If this is the case, check the supply conditions with the
electricity provider.
