17.3.1.4. AIR COOLED CONDENSER
Caution
Fin edges are sharp and can cause injury hazard. Avoid contact with them.
Condenser coils are composed of copper tubes and aluminium fins. In case of leaks due to damage or shock, the
coils must be repaired by one of the authorized Support Centres. To guarantee the best possible operation of the
condenser bank, the condenser surface must be maintained as clean as possible, and it must be void of foreign
materials (leaves, wires, insects, slag, etc.). A dirty coil will see its absorbed electrical power increase. In addition,
condensation pressure could increase and trigger a high pressure alarm.
Clean the air exchanger using a special product for aluminium-copper coils and rinse with water. Do not use hot
water nor steam, as these may increase the refrigerating fluid's pressure.
Caution
Avoid damaging the aluminium fins during cleaning. Never use pressurized water without
a wide diffuser. Concentrated and/or rotating water jets are strictly forbidden.
IT IS RECOMMENDED THAT THE DISCONNECT SWITCH BE PADLOCKED
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.
CAUTION
