2.2 STORAGE AND INSTALLATION LOCATION
If not in use, the refrigerator can be stored in its packaging in a dust free and protected site between 0°C and 50 °C, and
a specific humidity not exceeding 90 %. Should the stocking time exceed 12 months, please contact your local authorized
distributor.
If the refrigerator is not used, it will be placed in a site with the following conditions:
The machine must be protected from atmospheric agents and not directly exposed to sun light.
A seating base flat and capable to hold the weight of the machine.
Ambient temperature complying with the nominal data of the refrigerator.
The refrigerator should be located in a clean area, without forced air draft that can affect the fan control system.
Make sure to leave sufficient clearance (20 inches, 500 mm) around the refrigerator in order to allow an
adequate cooling of the machine and for maintenance and/or control operations.
The incoming gas must be free from smoke or flammable vapours which could lead to explosion or
fire risks.
2.3 UNPACKING
The packaging is made of carton or of cellophane. We recommend that you keep the original packaging for the device
in case it has to be transported to another location or sent to a service center. Dispose the various packaging materials
in compliance with the relevant rules locally in force.

No parts of the nitrogen system are under pressure.
No parts of the system are electrically powered.
Tubing to be connected to the refrigerator are free of impurities.
The pipes to be connected to the refrigerator does not weigh on the device.
All interconnecting piping has been tightened.
After having verified the points listed above, you can proceed to the installation of the machine.
1. Connect the refrigerator to the compressed nitrogen lines. If not already existing, we suggest to install
a by-pass allowing to isolate the machine from the plant, thus to facilitate eventual maintenance
operations.
2. Perform the electrical connection in accordance with any local laws and regulations after reviewing the
refrigerator electrical specifications and wiring diagram.
3. Power the refrigerator after having checked that the nominal voltage and line frequency are constant
and matching the nominal values of the machine. The user must provide the installation with an
adequate line protection and a ground terminal complying with the electrical rules locally in
force.
