(TABLE 3-5) FAN SPEED REQUIREMENTS
F. SETTING THE MINIMUM LOAD
Set the minimum load once the
maximum load has been set, set the
fan speed in the service function to
the minimum RPM setting. 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 CO2 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 17 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,
enter the Service function
another time.
• When you are done setting the
valve, press stop in the Service
function to return to normal run
mode
Please do not forget to replace the
protective cap on the gas valve!
