3.3.2 Checking the heat exchanger
After a long time of use dust may build up in the exchanger (pos. 5, figure 1) and block the airflow. It is important to
clean the exchanger regularly to maintain high efficiency. The heat exchanger in the Topvex FR03–11 can be taken out
of the unit. Wash in hot soapy water or use pressure air. Do not use detergent containing ammonia.
Note:
Make sure that the rotor motor is not exposed to moisture.

the heat exchanger out of the unit

changer block.

ing it straight up.
