When reassembling the leakage tray the
openings in the leakage tray must be on the
side of the condensation drain.
11. Inspect and if necessary clean the heat exchang-
er.
- Use a soft brush to clean the fins.
- Use a vacuum cleaner or air gun (no high
pressure) to remove dirt and dust.
Always clean against the direction of
the airflow. This prevent dirt from get-
ting stuck in the heat exchanger.
Standard heat exchanger only:
a. Submerge the heat exchanger several times in
hot water (max. 40 °C).
b. Rinse the heat exchanger with clean hot tap wa-
ter (max. 40 °C).
c. Clasp the heat exchanger between both hands
(on the coloured side surfaces) and shake the wa-
ter from the heat exchanger.
Do not use aggressive cleaning agents or
solvents.
If the fans also need maintenance do not re-
install the heat exchanger yet.
12. If no more maintenance is necessary install all
parts in reverse order, reconnect the power and
carry out the self-test in accordance with menu
P76.
Fasten the screws to a maximum of 1.5 Nm.
This is roughly equal to speed 2 of an aver-
age battery-powered drill.
