Procedure
- Remove the red painted transport brackets: for SF Multi remove brackets (2-Fig. 5.1); for other variants remove the brackets (one on each side of the frame).
- For SF Multi check the settings of the overload relays (Q21, -22, -23, -24 - Fig. 1.14).
- Connect the compressor electrically. See section 2.3.
- Close the condensate drain valve: valve (1-Fig. 1.9 on SF Multi) or the valve underneath the air receiver, if provided.
- Switch on the voltage. Start and stop the compressor. On 3-phase compressors, check for correct direction of rotation; if wrong, switch off voltage and reverse two incoming electric lines.
