Operating instructions
N.B.! When cleaning the heat recovery unit and the base of the battery box, do
not use more water than the drain (E) under the battery can remove from the ma-
chine. The battery must be cleaned with hot water at normal pressure. Do not aim
the water directly at the fan motor (F) on the end piece of the battery. The electric
motor may be damaged if it is rinsed with high-pressure water.

Remove the top panel (A) on the heat recovery unit box.
The safety valve (G) should be aerated/activated at least once a year.
Remove the cover plate (B) from the heat recovery unit by unscrewing the
wing nuts which fasten it in place. Lift up the heat recovery unit using the
lifting arm (C) to make it easier to remove.
Check from inside the machine that the drain (E) under the battery is not
blocked.
With the heat recovery unit removed, begin by cleaning the bottom plate of
the battery box. Then check that the drain (E) is not blocked.
Next, clean the heat recovery unit (D). Rinse between the cooling fins from
above. If the heat recovery unit is very dirty, a cleaning product with a neu-
tral pH which will dissolve grease can be used. Check the drain.
Finish by washing the base of the battery box again.
Replace the heat recovery unit using the lifting arm (C), attach the cover
plate securely (B) using the wing nuts, before fitting the top panel (A).
