Cleaning of condensor

JO960 creates much heat and therefore requires that the airflow is not
obstructed. The condensor (cooling unit, see No 4 on Figure 2) need to
be cleaned regularly.

Lukewarm water is perfect for cleaning. If heavily dirty a degreasing
compound can be used.

REMARK: Never use a high-pressure washer, it might damage the

condensor.

At the bottom of this part there are four (4) fuses.
