10. SERVICING AND MAINTENANCE
SERVICING
Servicing or maintenance of these unit must be carried out by experienced personnel with specific
training in refrigeration. Repeated check the safety devices and continuous cycling of control components
must be analyzed and corrected before being reset.
The simple design of the refrigeration circuit totally eliminates potential problems during normal unit
operation. No maintenance work is needed on the refrigeration circuit as long as the unit is operating
normally.
Ease of maintenance has been taken into consideration during the design stage such that the unit is easily
accessible for servicing and maintenance. By accessing from the front panel of the unit, servicing and
maintenance operation can be done easily. The electrical components are especially easy to access since
it is located in the terminal box on top of the front panel.
Under normal circumstances, these chiller require only a check and cleaning of air intake through the coil
surface only. These can be done monthly or quarterly depending on the surrounding where the units are
installed.
When the surrounding is very oily or dusty, then the coils must be regularly cleaned by a qualified air
conditioner service technician to ensure sufficient cooling capacity and efficient unit operation. The
normal life span might be shortened if no proper service is provided.
MAINTENANCE
For consistent performance and durability, always conduct proper and regular maintenance to the unit.
For prolong period of operation time, the heat exchanger will become dirty impairing its effectiveness and
reducing the performance of the units. Consult your local dealer about the cleaning of the heat exchanger.
No major maintenance or servicing needed for the internal water circuit in the unit except the water pump
failure. It is advised that regular check on the filter to be conducted and change the water filter if the filter
is dirty or choked.
Always check the water level in the system, in order to protect the moving components in the hydraulic kit
from over heating and excessive wear.
