4. Remove the five (5) screws in the top and bottom of
each fresh air damper located inside the hood area.
5. Using the Service Test guide in
—
, momentarily jump across the test terminals
one time for constant volume applications, or three
consecutive times for a variable air volume
application, to start the Minimum Ventilation Test.
6. With the supply fan “On” and rotating in the proper
direction, measure the return duct static pressure.
7. Using
, enter the desired amount of
fresh air and the return air static pressure reading to
obtain the proper damper opening dimension.
8. Loosen the adjustment screws on each side of the
damper and slide it downward to the required
opening.
9. Tighten the adjustment screws and re-install the
mist eliminators and the mist eliminator retainer
bracket.
10. Open the main power disconnect or the unit

to reset the RTRM.
11. Before closing the disconnect switch, ensure that
the compressor discharge service valve(s) and
suction service valve(s) are backseated.
