3.5 Tips for optimum use of the parking
cooler
• Keep windows and doors closed when operating
the parking cooler.
• Park in shady areas if possible.
• Darken the windows of the driver's cab if
possible.
• Keep parking cooler away from other heat
sources if possible (e.g. from cooling units of
refrigerated trailers).
• Thoroughly ventilate the heated-up passenger
compartment of the driver's cab or pre-cool it
with the vehicle air-conditioning system before
switching on the parking cooler.
• Operate the Cool Top Vario 10 E approx.
5 minutes together with the vehicle air-
conditioning system before using it while parked
to dissipate stored heat.
