In order to keep the unit operating reliably and efficiently it is necessary to periodi-
cally clean the condenser. ( The frequency depending on the location in which
the unit is installed. ) This operation is to be done with the mains turned OFF. We
advise use of an air jet blowing from the inside towards the outside. If an air jet
is not available then use a soft long haired brush on the outside of the conden-
ser taking care not to damage the condenser fins. WARNING condenser fins
have sharp edges.
