The air filter must be kept clean, never allow to be-
come choked with dust or dirt. If allowed to do so, the
performance of the unit will become impaired, resul-
ting in loss of air flow, freezing up of the evaporator
coil and possible component damage.
ACCESSING THE FILTER PAC4500AX/ET4500AX
Open the lower front panel, filter is located in front
of the evaporator. A second filter is fitted to the rear
panel on of an ET4500AX.
PAC5600AX Lift out the return air grille on the front
face of the unit, Fig 4. On refitting the filter ensure
that it is correctly positioned covering the whole
rear face of the grille. The filter (see Fig. 4) can be
washed in warm, soapy water, rinsed and shaken dry
before replacement. Frequency of cleaning depends
upon application and can only be determined by the
user. However, you should never allow more than two
months to elapse between cleaning. The probable
life of the filter will be about one year and spares are
available from the supplier of the unit itself.
