INSTALLATION

UNPACKING
In order to prevent the oil contained in the air-tight compressor from flowing into the cooling circuit, it is necessary to always carry, store, and handle the machine in a  vertical position, following the instructions found on the packaging.
If the machine was accidentally or purposely placed in a non-vertical position during transport, before operating the machine it should be kept in a straight position for  approximately 30 minutes to allow the oil to flow back into the compressor.

1. Remove cardboard and plastic covering.
2. Make sure that the machine has not been damaged.
3. Remove the plastic film from all the stainless steel panels.
4. Before operating, remove the green plastic plug(s) from the tap(s). (Fig. 1)

CAUTION
Dispose of packaging materials correctly.
Do not leave within reach of children.

POSITIONING

1. Place the machine on a sturdy horizontal surface.
2. For improved ventilation, maintain a distance of 6 in. between the unit and walls or other obstacles.
   Increase the distance if the obstacles are a heating source. (Fig. 2)
3. Leave 60 in. of free space in front of the machine to allow for easy use and maintenance. (Fig. 2)
4. Leave 10 in. of free space above the machine to allow for removal of lids. (Fig. 2)
5. When the machine is in place, adjust the rubber legs to level.
