Check Operating Pressures
1. Start the unit and allow the pressures to stabilize.
N No otte e:: If unit includes Modulating Dehumidification
Control option, pressure curves apply to the
cooling mode only.
2. Measure the outdoor air dry bulb temperature (°F)
entering the condenser coil.
3. Measure the discharge and suction pressure (psig)
next to the compressor.
4. Plot the outdoor dry bulb temperature and the
operating suction pressure (psig) onto the chart.
5. At the point of intersection, read to the left for the
discharge pressure. The measured discharge
pressure should be within ± 7 psig of the graph.
Economizer and Relief Air
Damper Adjustment
Exhaust Air Dampers
Verify that the exhaust dampers (if equipped) close
tightly when the unit is off. Adjust the damper linkage
as necessary to ensure proper closure. An access panel
is provided under each damper assembly.
Outside Air and Return Air Damper
Operation
The outside air and return air damper linkage is
accessible from the filter section of the unit. The
damper linkage connecting the outside air dampers to
the return air dampers is preset from the factory in the
number 1 position. Refer to
Table 48, p. 113 for the
appropriate linkage position for the unit and operating
airflow (CFM).
