Heat exchanger coil 

To maintain an efficient heat exchange 
the coils must be cleaned with a jet of 
compressed air and the circuit (water coil) 
must be free from air. 
To access the heat exchanger coil of the 
MBC accessory, disconnect the module 
from the unit and disassemble it .

Decommissioning

Disconnect the unit

All  decommissioning operations must 
be performed by authorized personnel 
in accordance with the national legi-
slation in force in the country where 
the unit is located.

• Avoid spills or leaks into the environ-

ment.

• Before  disconnecting  the  machine 

please recover:

•  the refrigerant gas;
•  Glycol mixture in the hydraulic 

circuit;

•  the compressor lubricating oil.

Before decommissioning the machine 
can be stored outdoors, providing that 
it has the electrical box, refrigerant 
circuit and hydraulic circuit intact and 
closed.

Disposal, recovery and recycling

The frame and components, if unusa-
ble, should be taken apart and sorted 
by type, especially copper and alumi-
num that are present in large quantities 
in the machine.
All materials must be recovered or 
disposed in accordance with national 
regulations.

RAEE Directive (only UE)

• The RAEE Directive requires that 

the disposal and recycling of elec-
trical and electronic equipment 
must be handled through a special 
collection, in appropriate centers, 
separate from that used for the di-
sposal of mixed urban waste.

• The user has the obligation not to 

dispose of the equipment at the 
end of the useful life as municipal 
waste, but to send it to a special 
collection center.

• The units covered by the RAEE 

Directive are marked with the 
symbol shown above.

• The potential effects on the envi-

ronment and human health are 
detailed in this manual.

Additional information can be 
obtained from the manufacturer.

DIAGNOSIS AND TROUBLE-
SHOOTING

Fault fi nding

All units are checked and tested at 

the factory before shipment, howe-

ver, during operation an anomaly 

or failure can occur.

THE FAULT; REPEATED RESET 

MAY RESULT IN IRREVOCABLE 

DAMAGE TO THE UNIT.

At the end of their operating life, 

the URX_CF units must be disposed 

of according to the present laws.

The main components including 

the unit of the URX_CF series are 

made from:

• Galvanised sheet steel (panels , 

condensate drain pan, fans);

• aluminium sheet metal (coil fins, 

dampers, electrical motor casing);

•  copper (coil tubes, electric motor 

winding );

• polyurethane foam (insulation of 

the sandwich panels);

• rock wool (silencers);

• the cooling gas is recuperated by 

specialised personnel and forwarded 
to the disposal centre;

• the compressor lubrication oil is 

also recuperated and forwarded for 
disposal.

  PERIODIC COMPONENT OPERATIONS  

Filters   

Check their cleanliness twice a week 

Heat exchanger coil  

Check integrity of pack each year 

Condensate pan  

Check cleanliness each year 

Heat recovery unit  

Check integrity of the deck each year 

The table indicates the maintenance operations 
concerning each component, indicating the 
type of check to perform and when it should 
be performed. The frequency is approximate 

and varies depending on the working and 
environmental conditions in which the heat 
recovery unit operates.
