Please note:
o
The more humid the air, the more quickly the frost will accumulate.
o
Traces of residual frost may persist, however repeated defrost cycles should not cause these
accumulations to grow.
o
The thermodynamic defrost works correctly down to -7 ° C. Below this temperature the machine must be
switched off.
o
Quadro the weather is cold and humid, the heat pump could engage in subsequent defrosting cycles.
The time dedicated to defrosting is subtracted from the time taken to heat the pool, thus reducing the
caloric power supplied by the machine.
o
The speed and efficiency of the defrosting phase directly depend on the pool water temperature.

DEFROST CYCLE
As the air passes over the evaporator fins, the water contained condenses into small drops. If the
ambient air is cold, these droplets could freeze and therefore would no longer be able to drain by
gravity from the bottom of the machine. The frost then slowly accumulates on the fins, creating an
insulation over time that would prevent the transfer of heat from the air to the heat transfer fluid.
The heat pumps are equipped with a device that automatically detects the excessive accumulation
of ice and triggers the defrost by inversion of the cycle.
The defrosting phase lasts a few minutes. The heat pump then returns to normal operation and, if
necessary, another defrost phase can be activated. An audible click (movement of the 4-way valve)
accompanies the beginning and the end of the cycle inversion.

PERIODIC MAINTENANCE
Regularly check that dirt has not accumulated on the evaporator (pollen, earth, cuts, etc.).
Clean if necessary:
➢
o stop and unplug the machine,
➢
or rinse gently with water (do not use a high pressure hose, this could damage the fins)
➢
or use a soft brush to clean between the fins
➢
Depending on the rate of dirt accumulated on the evaporator, the floor of the machine must be
cleaned regularly by a professional to prevent blocking or blocking the flow of condensate.
➢
Periodically check that the impeller blades are not dirty or damaged.
➢
Check the heat transfer fluid pressure and electrical connections annually by a professional.
➢
Clean the cabinet that houses the machine Clean the cabinet with soapy water and a soft cloth.
Never use abrasive products or organic solvents.

WINTERING
➢
Stop the machine
If the heat pump is heating up, stop it.
