S-201 AIR HANDLER EXTERNAL STATIC

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.

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 or

a BBA/BBC blower to determine airflow, supply static must

be taken between the "A" coil and the furnace.

TOTAL EXTERNAL STATIC

S-202 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.
