3 About the unit and options
WARNING
NEVER replace a fuse with a fuse of a
wrong ampere rating or other wires
when a fuse blows out. Use of wire or
copper wire may cause the unit to
break down or cause a fire.
WARNING
▪ After finishing the electrical work,
confirm that each electrical
component and terminal inside the
electrical components box is
connected securely.
▪ Make sure all covers are closed
before starting up the unit.
WARNING
NEVER touch the person receiving an
electrical shock, or you could suffer
one too. Do NOT touch the person until
you are sure power is turned off.
Electrical shocks always need
emergency medical attention, even if
the person seems to be fine.
WARNING
A magneto thermal circuit breaker,
having a contact separation in all poles
providing full disconnection under
overvoltage category III condition,
MUST be installed in the fixed wiring.
In case of multiple units each unit must
have its own circuit breaker.
Note that this magneto thermal circuit
breaker should not be used to turn the
unit on and off under normal operating
conditions. For that, one should use
the controller.

3 About the unit and options
3.1 About the system
The MPC and BPC units are refrigeration indoor units which allow to
refrigerate air through vaporising a liquid refrigerant (Hydrocarbon
R290 type) at low pressure in a heat exchanger (evaporator). The
resulting vapour is brought back to liquid state by mechanical
compression at a higher pressure, followed by cooling in another
heat exchanger (condenser).
Defrosting takes place automatically in pre-set cycles, by injecting
hot gas; manual defrosting is also possible.
INFORMATION
The A-weighted sound pressure level of the unit is less
than 70 dBA.
The measurement complies with UNI EN ISO 3746: 2010.
