MAINtENANCE

 

—

the connections on the water side are clean and do not 
show signs of leaks.

4.6 Maintenance

9 

before any intervention on the unit, make sure that the cir-
cuit is isolated and that there is no voltage. Note that it may 
take 5 minutes for the circuit capacitors to fully discharge 
after isolating the circuit. Only qualified personnel are au-
thorized to work on the VFD.

In case of alarm or persistent problem related to the VFD, contact 
the assistance service.
VFDs equipped with units do not require an insulation test, even 
if they are replaced; they are in fact checked systematically be-
fore delivery. In addition, the filter components installed in the 
VFD can distort the measurement and can also be damaged. If 
there is a need to check the insulation of the components of the 
appliance (fan motors and pumps, cables, etc.), the VFD must be 
disconnected from the power circuit.

4.7  Refrigerant volume

The unit must be started in cooling mode to find out if the unit 
load is correct by checking the actual subcooling.
A small loss of refrigerant compared to the initial load will be 
evident in the cooling mode and will affect the subcooling value 
obtained at the outlet of the air heat exchanger (condenser), but 
will not be visible in heating mode.

9 

It is therefore not possible to optimize the refrigerant charge 
in the heating mode after a leak. The unit will need to be 
started in cooling mode to check if an additional load is re-
quired.
