In high-temperature conditions, it is advisable to first open the windows of the HOWO tractor truck to facilitate ventilation if the vehicle has been exposed to direct sunlight for an extended period. After allowing the hot air to escape, the air conditioning system may be activated. It is important to ensure that the air conditioner is switched off prior to the vehicle coming to a stop.
To safeguard the compressor, there should be a minimum interval of 3 minutes between consecutive compressor activations, and each activation should last at least 2 minutes.
Avoid frequently turning the air conditioner on and off, and limit the activation of the air conditioner compressor to no more than 10 times within an hour.
Regular maintenance of the air conditioning filter screen, condenser core, and dust screen is essential for optimal performance.
