1 − When the thermostat is set to FAN ON," the indoor
blower will run continuously at a percentage of the sec-
ond−stage cooling speed when there is no cooling or
heating demand. The percentage is set using DIP
switches 6 and 7.
2 − When the SLP98DFV is running in the heating mode,
the integrated control will automatically adjust the
blower speed to match the furnace firing rate. This
speed can be adjusted up or down by 7.5% or 15% us-
ing DIP switches 14 through 16 for the low heat speed
and 17 through 19 for the high heat speed.
3 − When there is a cooling demand, the indoor blower will
run on the cooling speed designated by the positions
of DIP switches 8 through 11.
Generator Use − Voltage Requirements
The following requirements must be kept in mind when
specifying a generator for use with this equipment:
D The furnace requires 120 volts +
10% (Range: 108
volts to 132 volts).
D The furnace operates at 60 Hz +
5% (Range: 57 Hz to
63 Hz).
D The furnace integrated control requires both polarity
and proper ground. Both polarity and proper grounding
should be checked before attempting to operate the
furnace on either permanent or temporary power.
D Generator should have a wave form distortion of less
than 5% THD (total harmonic distortion).
