• Servicing
Servicing or maintenance of these units must be carried out by experienced personnel with specific training in refrigeration.
Repeatedly check the safety devices and continuous cycling of control components. These items must be analyzed and
corrected before being reset.
The simple design of the refrigeration circuit totally eliminates potential problems during normal unit operation. No mainte-
nance 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 from the
service panels. The electrical components are especially easy to access since it is located in the terminal box in the front
service panel (Figure 7).
Under normal circumstances, these chillers required only a check and cleaning of air intake through the coil surface. 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 condition 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 is needed for the internal water circuit in the unit except the water pump failure. It is
advisable to conduct regular check on the filter and change the water filter if it 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.
