Replacement of flexible pipes
It is advised to replace the pipes when changing the oil. Loosen the connections, replace them and tighten the connections again
firmly. Now change the oil.
Replacement of the transmission belt (fig.12)
Act in the following way:
• loosen the 4 screws (C) until the screw compressor support
plate can be moved. Loosen the counter nut (B) and turn the screw (A)
in an anti-clockwise direction until the belt is completely relaxed.
• Remove the belt and replace it
• Tighten the screw partially (A), block the counter nut (B) and
check the frequency value by means of the relative instrument (see
"check belt tension" page12).
• If necessary, repeat the operations described until the optimal
value stated in table 1 has been reached.
Higher value = belt too taught
Lower value = belt to loose
Once the desired value has been reached, block all components
firmly and re-mount the rear panel before re-starting the compressor.
