2. Warnings

Do not operate or maintain this refrigeration unit until you have familiarized yourself completely with
the equipment and operation of this unit by reading the instructions in this manual.
Do not perform any welding on the unit before disconnecting the power plug. Furthermore, discon-
nect the power measurement module and main controller (and modem if present).
Disconnect the main power supply to the unit before inspecting the interior of the controller box.
The unit is charged with R134a or R513A and ester oil BSE 55. Do not use any other refrigerant or
oil. Do not use contaminated refrigerant or oil. Never release any refrigerant into the atmosphere.
Use recovery equipment according to present legislation.
During maintenance, please observe that refrigerants operate with high and low temperatures in
combination with high pressures, which may cause personal injuries if not handled properly.
During recovery and maintenance of the refrigerant, personal protection equipment must be worn.
Do not trap any liquid refrigerant inside pipes during soldering work. This may lead to an explosion
of the pipes.
Please note that some unit models do not have Schräder valves installed for Psuc and Pdis transmit-
ters.
We do not recommend cleaning the inside of a reefer container with soap/chemicals with a PH value
below 7. However, if this occurs, clean the evaporator coil through the inspection hatches with a soap
that has a PH value between 7 and 9. This cleaning is vital to reduce the risk of copper damage in
the evaporator coil.
Do not enter the container, including opening the service hatches, when the oxygen level is below
20.9%. Ventilation is necessary before entering, either for repairing the unit or unloading. Stay away
from doors while venting.
