FILTERS, THROWAWAY
The type of throwaway filter most commonly used on fan coil units should be replaced on a regular basis. The time interval
between each replacement should be established based on regular inspection of the filter and should be recorded in the log
for each unit. Refer to the chart on page 20 for recommended filter size for each product type and size. If the replacement
filters are not purchased from the factory, the filters used should be the same type and size as that furnished from or
recommended by the factory. Consult the factory for applications using filter types other than the factory standard or
optional product.
