▪ Reduce the opening time of the cold room doors.
▪ Make sure the goods are at their correct storage temperature
before loading.
▪ Make sure that a good airflow is possible between the stored
goods.
▪ Check that the evaporator is ice-free. Ice forms on the evaporator
preventing air from flowing regularly. If necessary increase defrost
termination temperature by some degrees or increase frequency
of defrosts.
▪ Make sure that cold room doors are perfectly tight.
▪ Perform any inspection of the load through the inspection door on
the side of the trailer, if present. This ensures less cold loss during
any inspection.
INFORMATION
When the cold room door is closed, a micro switch (NO
contact) sends a signal to the unit.

Maintenance and service
8.1
Overview: Maintenance and
service
The user has to perform the maintenance as prescribed in
22].
NOTICE
At every maintenance session, the entire unit should be
checked for rust, breaks or cracks and general
contamination. Any problem that may occur should be
addressed (or reported if necessary) immediately.
NOTICE
Maintenance MUST be done by an authorised installer or
service agent.
We recommend performing maintenance at least once a
year. However, applicable legislation might require shorter
maintenance intervals.
CAUTION
Before accessing terminal devices, make sure to interrupt
all power supply. Then wait for 10 seconds for the
electrical condensers to discharge before opening the
electrical box cover.
DANGER: RISK OF BURNING/SCALDING
Allow the PM generator, the engine, the engine exhaust,
the engine- cooling system, the evaporator defrost heaters
and the water discharge heater to cool down before
touching any of these parts.
DANGER: RISK OF BURNING/SCALDING
Allow the engine, the engine exhaust and the engine-
cooling system to cool down before performing any fluid
change.
WARNING
If diesel leaks from the fuel system, it evaporates. These
vapors are irritating to eyes, respiratory system and skin
and can ignite if an open flame is in the area.
WARNING
To prevent electrical shocks or fire:
▪ Do NOT rinse the unit.
▪ Do NOT operate the unit with wet hands
▪ Do NOT place any objects containing water on the unit.
CAUTION
Do NOT touch the heat exchanger fins. These fins are
sharp and could result in cutting injuries. Wear safety
gloves if you have to work on or around the heat
exchanger fins.
NOTICE
Be careful not to damage any part of the unit, it may result
in appliance problems.
About the refrigerant
This product contains fluorinated greenhouse gases. Do NOT vent
gases into the atmosphere.
Refrigerant type: R452A
Global warming potential (GWP) value: 2140
NOTICE
Applicable legislation on
fluorinated greenhouse gases
requires that the refrigerant charge of the unit is indicated
both in weight and CO
2
equivalent.
Formula to calculate the quantity in CO
2
equivalent
tonnes:
GWP value of the refrigerant × total refrigerant
charge [in kg]/1000
Contact your installer for more information.
WARNING
▪ R452A is a non-combustible refrigerant; it normally
does NOT leak. If the refrigerant does leak and comes
into contact with open flames, this may result in the
formation of a harmful gas.
▪ Turn OFF any combustible heating devices, ventilate
the area, and contact the dealer from where you
purchased the unit.
▪ Do NOT use the unit until a service person confirms
that the part from which the refrigerant leaked has been
repaired.
