Refrigeration dryer: Connecting the transformer according to the power supply.
The refrigeration dryer transformer has tappings for various power supply voltages.
1. Check that the correct connections are made for the supply voltage provided for the machine.
2. If necessary, re-connect the transformer to match the power supply voltage.
Further information The electrical diagram in chapter 13.4 contains further details of the power supply connection.
6.5 Connecting the condensate drain
A threaded hose connection is provided to connect the drain hose to the condensate drain outlet.
Condensate must drain freely.
The illustration shows typical installations.
Condensate flows into the collecting line from above, thereby preventing any backflow to the com‐
pressor.
