envisaged by the European Union Machine Directive.
All of the e-MovAir series air handling units are applied with a danger sign to warn of the presence of
MALFUNCTIONING
Warning from the low
pressure regulator of
the refrigerant circuit
Warning from the high
pressure regulator of
the refrigerant circuit
moving parts.
IT IS RECOMMENDED, EVEN IF THIS IS NOT THE
MANUFACTURER'S RESPONSIBILITY:
•
To fit the air handling unit with an isolating switch,
especially if the electrical panel is not located nearby, so
as to be able to disconnect power without the danger of
interference or use by third parties.
•
To install the earth system according to the standards
in force.

standards in force in the country in question.
The following materials are used in the construction of the unit:
•
Galvanised steel plate and/or plastic coated and/or stainless steel;
•
Aluminium;
•

•
Polyurethane and/or glass wool or mineral wool;
•
Plastic;
•
Refrigerant gas R401A (to recycle and dispose with proper cycle);

POSSIBLE CAUSE
Low level/charge of the
refrigerant gas
Block of the thermostatic
expansion valve
No thermal exchange on
the heat coil, air side
Refrigerant Gas load
exceeding the request
Obstruction of the
condensing coil
Reduction of the fans on
the refrigerant side
CONTROL
Check of the pressure
gauge
Of the thermostatic valve
appears with frost
Check the fan of the flow
Verify the pressure gauge
Check of the flaps surfaces
of the coil
Check the proper working
of the fans and of the
round regulator (if present)
25
POSSIBLE SOLUTION
Fill up of the refrigerant
gas
Substitution of the
blocked valve
Check of the electrical
absorption, air flow and
tightness and rotation of
the belt
Reduce the gas load
Clean the surface of the
coil with compressed air
Reactivation of the
normal working speed
