Cleaning the outer casing
If necessary the outer casing can be cleaned using a damp cloth.
Care must be exercised so that the heat pump is not scratched when
cleaning. Avoid spraying water into the grilles or the sides so that water
penetrates into F2120. Prevent F2120 coming into contact with alkaline
cleaning agents.
In event of long power cuts
In the event of prolonged power failures it is recommended that the part
of the heating system located outdoors is drained. Your installer has in-
stalled a shut off and drain valve to facilitate this. Call and ask your installer
if you are unsure.
Silent mode
The heat pump can be set to "silent mode", which reduces the heat pump's
noise level. The function is useful when F2120 must be placed in noise
sensitive areas. The function should only be used for limited periods as
F2120 may not reach its dimensioned output.
