8.5 Fuses
Fuses may occasionally require changing especially with installations where the voltage is not
consistent. Drops in voltage can create brief periods of high amp draw, causing fuses to blow.
Always replace fuses with those of the equivalent rating with regard to: 1) amperage, 2) voltage
and 3) speed. For instance – compressors are and motors are inductive loads which require time
delay fuses where electric reheat and humidifi ers are resistive loads requiring fast acting fuses.
8.6 Heating Elements
Heating elements do not normally require maintenance. However, 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 an unpleasant odor. To help avoid a problem, periodic cleaning is recommended.
8.7 Refrigerant Filter Drier
Factory installed refrigerant fi lter driers do not require maintenance or replacement unless the system
has been opened. When replacing compressors or other repairs that open the refrigeration
system to the atmosphere, it is always advisable to replace the fi lter drier. The equivalent type
and size should be used.
