Filters
A filter is supplied with the furnace (except 58BGA). It is
NECESSARY THAT ALL FURNACES BE EQUIPPED
WITH A FILTER.
If a different type of filter is used, it must be an equivalent high
airflow capacity
.
Keeping Filters Clean
As a homeowner, this is your most important responsibility. A
dirty filter reduces the efficiency of your system, causes erratic
performance of controls, and could result in damage to the mo-
tor or heat exchanger.
1. Inspect filters at regular intervals depending upon dirt con-
ditions. For new homes, check filters every week for 4 con-
secutive weeks. In all cases, inspect your filters at least every
3 to 4 weeks when the system is in constant operation. Re-
place or clean filter at least at the beginning of each season
(heating & cooling) and thereafter as needed.
2. If the permanent filter supplied with the unit becomes dirty,
it can be cleaned with cold water and soap.
Be sure that the filter is thoroughly dry before installing back
into the furnace.
Lubricating Motors
Direct drive motor and blower assemblies are factory lubri-
cated and normally do not require oiling. If oiling is required,
lubrication of the blower motor is to be performed only by a
qualified service agency.
WARNING
Never operate unit without a filter or with filter ac-
cess door removed. Failure to adhere to this warn-
ing could lead to a hazardous condition which
could lead to equipment damage and bodily harm.
