I have a Goodman AEPF 183016 air handler. How do I change the DIP swishes to add CPM? The product specifications state that you can speed up the fan using the #7 dip switch. Where are the DIP Switches?

I DO NOT suggest you play with the dip switches if you have a ECM or variable speed motor unless you have the proper tools to test the CFM of air movement. Most units are setup during the install for proper operation.

Below is a portion of the manual for that unit.

S-202 DUCT STATIC PRESSURES AND/OR
STATIC PRESSURE DROP
ACROSS COILS
This minimum and maximum allowable duct static pressure
for the indoor sections are found in the specifications
section.
Tables are also provided for each coil, listing quantity of air
(CFM) versus static pressure drop across the coil.
Too great an external static pressure will result in insufficient
air that can cause icing of the coil. Too much air can cause
poor humidity control and condensate to be pulled off the
evaporator coil causing condensate leakage. Too much air
can also cause motor overloading and in many cases this
constitutes a poorly designed system.
S-203 AIR HANDLER EXTERNAL STATIC
To determine proper air movement, proceed as follows:
1. Using a draft gauge (inclined manometer), measure the
static pressure of the return duct at the inlet of the unit,
(Negative Pressure).
2. Measure the static pressure of the supply duct, (Positive
Pressure).
3. Add the two readings together.
TOTAL EXTERNAL STATIC
NOTE: Both readings may be taken simultaneously and read
directly on the manometer if so desired.
4. Consult proper table for quantity of air.
If external static pressure is being measured on a furnace to
determine airflow, supply static must be taken between the
"A" coil and the furnace.

TOTAL EXTERNAL STATIC
S-204 COIL STATIC PRESSURE DROP
1. Using a draft gauge (inclined manometer), connect the
positive probe underneath the coil and the negative probe
above the coil.
2. A direct reading can be taken of the static pressure drop
across the coil.
3. Consult proper table for quantity of air.
STATIC PRESSURE DROP
If the total external static pressure and/or static pressure
drop exceeds the maximum or minimum allowable statics,
check for closed dampers, dirty filters, undersized or poorly

laid out duct work.
