WARNING
When the unit is operating in grid mode and a power
blackout occurs, the automatic road mode start-up function
is activated. This means that the unit will start-up in road
mode.
This function MUST be disabled by the operator when the
cold room is parked in a confined space or an area where
fumes from the engine could become trapped and cause
serious injury or death (e.g. indoor parking, ferry).

Loading the goods
CAUTION
Turn on the light before entering the cold room, and take a
portable torch with you.
NOTICE
Do not cover the air intake and -outlet openings towards
the condenser and evaporator of the unit.
Maintaining the right temperature guarantees the preservation of the
quality of the transported goods.
Air circulation is of absolute importance to keep a uniform
temperature throughout the entire cold room. Insufficient air
circulation can cause heat pockets or ice formation.
For this reason:
▪ Use pallets that facilitate air circulation under the goods,
protecting them from the heat coming from the cold room floor.
▪ Place the goods away from the cold room walls. Use spacers if
necessary.
▪ Leave a space of approximately 20 cm between the goods and
the cold room ceiling.
▪ Stack heat generating products, such as fruit and vegetables, in a
way to create sufficient space to remove the generated heat by
cold air circulation.
▪ Stack products which do not generate heat, such as meat and
frozen foods, close to each other toward the center of the cold
room.

Pre-trip inspection (PTI)
INFORMATION
This inspection is a function test of all the unit's
components. It is recommended to perform this inspection
before long trips.
It is best to perform the inspection without cargo in the cold
room.
Before starting the engine
▪ Drain water from bottom of fuel tank.
▪ Drain water from the water separator on the pre-fuel filter of the
trailer fuel tank.
▪ Check air cleaner and hoses (only if there are traces of Diesel
fuel, engine coolant or oil inside the unit).
▪ Check engine oil level
▪ Check coolant level. Always use an industrial ladder (or other safe
platform) to inspect the coolant tank located at the top of the unit.
▪ Check condition of water pump belt.
▪ Check battery cables and terminals.
▪ Check evaporator coil for cleanliness.
▪ Check condenser/radiator coil cleanliness.
▪ Check all defrost water drains.
After starting the engine
▪ Check fuel lines and filters for leaks.
▪ Check oil filter for leaks.
▪ Check coolant hoses for leaks.
▪ Check condenser fan for proper airflow.
▪ Check evaporator fan for proper airflow.
▪ Check for unusual noises.
During PTI and after PTI is finished
▪ Check for proper temperature control. It is recommended to do the
PTI without cargo in the cold room. If cargo is present, it is the
responsibility of the operator to ensure that the temperature does
not rise above the permissible value.
▪ Check the PTI output results (failed steps and malfunctions
signal).
