$lbwex'-ÁdjugFment - K blower speed is
not correct; the fan control switch may not
operate correctly. If an adjustable fan switch
is used with the unit, do not attempt to adjust
this switch iuntil the blower performance has
been checked ,;as described below,.
The temperature rise across the furnace
should be between 70F and 1Û0F . The blowers
are set .at, the factory to give approximately
85F temperature rise. Check this setting by
insertipg^. one thermometer in the return air
duct at the unit and another thermometer in
the plenum. Be sure the thermometer does
not ';see'^ the heat exchanger. The effect of
ráchaut heat will giv-e false readings. Allo^
:the unit to .Operate until the readipg^ on both :
di^rmòipetè have stabüii^çd. If the terobor-
.^fure ipise is too little or too greatf aidju^

Important: It should be noted that air delivery
rate will vary with applied voltage at the
blower motor. If there ie any doubt about the
value of fluctuation of the supply voltage,
consult your local electric utility.
