8.5 Fuses
Always replace fuses with those of the equivalent rating with regard to: 1) amperage, 2) voltage,
and 3) speed. For instance compressors and motors are inductive loads which require time delay
fuses. Electric reheat and humidifi ers are resistive loads requiring fast acting fuses.
8.6 Heating Elements
Heating elements do not normally require maintenance. However sometimes they may accumulate
a fi lm of dust or dirt when unused for extended periods of time. When energized, the burning debris
can create smoke or unpleasant odor. To help avoid this, periodic cleaning is recommended.
8.7 Refrigerant Filter Drier
Factory installed refrigerant fi lter driers do not normally require maintenance. When replacing
compressors or other repairs that open the refrigeration system to atmosphere, it is advisable to
replace the fi lter drier. The equivalent type and size should be used.
