C. Ventilator should open to the position
set by the "PP" potentiometer. Cycle the
potentiometer from full open to full closed.
Observe damper blade operation throughout
travel to assure free, unobstructed movement.
Return "PP" potentiometer to desired position
for pre-purge airflow (refer to graphs 1 and 2
on pages xx-xx). Move the "PP" jumper to the 0
position. Ventilator should open to the position
set by the "OCC" potentiometer.
Energize Y; ventilator should open to the
position set by the "Y1" potentiometer.
Energize Y1; ventilator should open to the
position set by the "Y2" potentiometer.
D. De-energize evaporator blower. Damper blade
should close.
E. If pre-purge function is desired, move "PP"
jumper to the 30-, 60-, or 90-minute position
depending on desired pre-purge time.
F. This completes ventilator checkout.
12. Replace mist eliminator. Be sure it is installed with
