Recommendations Concerning Safety And General Operation - Procopi CLIMEXEL HC-HH Série Notice D'installation Et Conseils D'utilisation

Thermodynamic defrosting:
If the ambient air is very humid (rain, fog, etc.) and the air temperature is relatively cool (below 15° C), frost can rapidly
accumulate on the evaporator fins and thus hinder recovery of calories by the heat transfer fluid.
The frost must be melted before this phenomenon becomes too pronounced.
All CLIMEXEL heat pumps are equipped with an automatic thermodynamic cycle inversion defrosting system:
When the temperature sensor located on the fluid circuit at the evaporator inlet detects an abnormal drop in
temperature, the regulator causes a 4-way valve to deviate the circulation of gas in the system as described below :

The roles of the evaporator and condenser are swapped: The fluid brings calories to the fin heat exchanger to melt the
ice. The fan remains stopped while the system is defrosting. When the temperature detected by the sensor increases,
defrosting is finished and the 4-way valve switches back to the normal cycle.
II. Recommendations concerning safety and general operation
While the machine is running, so ts of the heat transfer fluid circuit can become very hot, and other parts very
cold. Access to the parts of the heat pump located behind the machine's panels is reserved to qualified professionals.
Never insert any object through the slots in the propeller grill.
Handling:
Handle the machine with care, never leave it lying on its side.
Electricity:
All wiring should be carried out by a qualified electrician in accordance with the rules of the art and, notably,
according to the standards in effect in the country of installation .
