To set the water temperature on the MEFE CAT 157SK20:
1. Ensure the equipment is ready and filled with water to the proper level (3–5 cm above the axle tube of the rear dehairing shaft). 2. Switch on the main switch on the wall control cabinet. 3. Rotate the “heating ON” control on the wall cabinet to position I. 4. Wait until the water reaches the desired temperature of 62°C, indicated by the yellow indicator light turning off.
