F. SETTING THE MINIMUM LOAD
Set the minimum load once the maximum load has been set, turn the knob until the minimum RPM setting
has been reached. In order to set or adjust the minimum load, turn the screw [2] for the minimum setting (first
remove the protective cap). Turn the screw clockwise to increase or counter clockwise to decrease the CO
2
percentage. On the HW 599, you only are allowed to set the gas valve at the right side; the left gas valve is set by
the manufacturer.
See Section H, page 19 for special instructions on replacing both gas valves in a model 599.
• If the measuring process takes more than 40 minutes, the appliance will return to the automatic mode.
If so required, press the Service button another time.
• When you are done setting the valve, press the Service button again to return to normal run mode
Please do not forget to replace the protective cap on the gas valve!
