4.3. CLEANING THE CONDENSER
In order for the conservation unit to work correctly and
efficiently, the air condenser must be kept clean to allow
free airflow. This operation should be done at least
every 30 days. This can be done by using a non-metal
brush to remove all the dust and lint from the condenser
fins. We suggest you use a vacuum cleaner to prevent
the dust from going into the environment. If there are
any greasy deposits, use a brush soaked in alcohol.
Do not scrape the surface using sharp or abrasive
objects.
Always use protective gloves, glasses and masks
to protect the respiratory tract during cleaning.
