During the summer, or when temperatures are higher than 20°C, it is best to shut off the heating circuit, espe-
cially if you intend to use the A/C (optional).
Slacken off nut A, unscrew nut B and rotate scale C; cock D is located on the chassis under the cab, turn the
lever 90° CW to close the circuit.
During the winter, or when temperatures are low, open the circuit by turning the valve lever 90° CCW.
