SECTION 2 - OPERATION

2.Rotate the temperature control knob, 1, counterclockwise (toward the red) to increase the temperature and clockwise (toward the blue) to decrease the temperature.

3.There are four positions on the pressurizer fan switch, 2. The full counterclockwise position is off. Each detent in the clockwise direction increases the speed of the fan. The fan speeds are low, high, and purge.

4.The recirculation knob, 3, controls the mix between external air and recirculated cab air. To increase the amount of fresh air entering the cab, rotate the knob counterclockwise. Rotate the knob clockwise to recirculate the cab air. Do not block the recirculation vent, 4, when recirculating cab air.

NOTE: The left-hand side of the cab roof has a second recirculation vent that has a fixed opening and is not adjustable.

5.To dehumidify the cab air during cold weather, use the heater in conjunction with the air- conditioning system to reduce air humidity. Turn the air conditioner on and turn the recirculation knob clockwise to recirculate the cab air. Place the temperature control knob to the desired heat level.

Air Conditioning

1.The air conditioning is activated by a two- position rocker switch, 1. An indicator light on the switch will glow when the air conditioning is activated.

NOTE: The air-conditioning system uses R134A refrigerant. DO NOT mix with other refrigerants. DO NOT attempt to top off the system with any other refrigerants. Rely on a qualified technician for all air conditioning repairs.

2.Rotate the temperature control knob, 2, counterclockwise (toward the red) to increase the temperature and clockwise (toward the blue) to decrease the temperature.

3.There are four positions on the pressurizer fan switch, 3. The full counterclockwise position is off. Each detent in the clockwise direction increases the speed of the fan. The fan speeds are low, high, and purge.
