When units are delivered on site they are not always required immediately and are sometimes put into storage. In
the event of medium to long-term storage, we recommend the following procedures :
- Ensure that there is no water in the hydraulic systems.
- Keep the heat exchanger covers in position.
- Keep protective plastic film in position.
- Ensure the electrical panels are closed.
- Keep all items and options supplied in a dry and clean place for future assembly before using the equipment.
It is strongly recommended to store units is a dry, sheltered place (in particular for units that will be installed
indoors).

3.2.1 - Safety instructions
Installation, start up and adjustment of this equipment can be dangerous if certain system specific factors are
ignored, such as operating pressures, electrical components, locations (roofs, terraces and other structures located
well above ground level).
Only highly qualified contractors and technicians with sound knowledge of this type of equipment, are authorised
to install, start up and service it.
During any service operations, observe the recommendations given on labels or instructions sent with the
equipment, as well as any other applicable safety procedures.
- Follow all safety rules and regulations
- Wear protective glasses and work gloves
- Handle heavy or bulky equipment carefully during lifting and moving operations, and when setting it on the ground.
CAUTION : BEFORE EACH SERVICE OPERATION MAKE SURE THAT THE UNIT POWER SUPPLY
IS PROPERLY ISOLATED AND LOCKED OUT.
NOTE : SOME UNITS MAY HAVE A SEPARATE 230V CONTROL SUPPLY THAT REQUIRES
SEPARATE ISOLATION. PLEASE CHECK THE WIRING DIAGRAM.
3.2.2 - Handling
Handling operations must be carried out by qualified personnel. Comply strictly with lifting instruction pasted on the
unit. Unit handling operations must be carried out carefully to avoid jolting the frame, the panels, the electrical box,
the condenser coil fins, etc....
NOTE :
The heat exchangers of the condensers could be protected from damage during transport by plastic plates.
The machine is also wrapped in packing foil. It is recommended to leave this protection in place during any
transport and lifting operations, and not to remove the plastic plates until commissioning (take care that
the protecting foil wrapping is not blown away!).
NOTE :
Rubber anti-vibrations mountings (AVM) & factory accessories are to be found in the control panel for
shipping. If the unit is mounted on anti-vibration mountings, these should be fitted to the unit before final
positioning.
