SECTION 2 - OPERATION

4.The recirculation knob, 4, 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 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.

IMPORTANT: Always turn the air conditioner off when cooled or dehumidified air is not required. For proper air conditioner operation, the cab air filter must be serviced regularly.

Pressurizer Vents

The pressurizer fan has several adjustable vents to direct air flow as required. All vents can be rotated to adjust direction and have adjustable fins to direct the angle of air flow. The forward vents, 1, can be adjusted for the front or side windows. The rearward vents, 2, are for operator comfort.

For additional comfort, a floor vent, 1, is provided at the bottom of the right console.
