The air conditioning should be operated for at least five minutes each week, even in cold weather. This is to prevent poor lubrication of the compressor internal parts, and to maintain the air conditioning in the best operating condition.

If this procedure is not followed, the system may emit an unusual odour. This is not a fault in the system.
