FIGURE 2.13

Overriding EEV Output

The valve can also be opened or closed using the EEV
service tool (Bard Part # 2151-021). This magnetic
EEV service tool (shown in Figure 2.14) is used to
manually open the EEV. To do this, remove the EEV
stator coil (red color with retaining nut on top), slide
the magnetic tool over the shaft where the stator was
removed and turn in a clockwise direction to open the
valve to the full open position (directional arrows are
provided on the tool). Opening the valve to the full
open position will aid in the refrigerant reclamation and
evacuation processes.
Following the above procedure, reapply the EEV stator
coil and retaining nut. Upon powering the unit back up,
the control board will automatically drive the EEV back
to the fully shut position, and then back to the 20%
open position prior to starting the compressor back
up. Once the compressor starts, the control board will
again modulate the EEV position to control the system
superheat.

System Pressures

To view system pressure and temperatures during this
process:
1. From the Status screen, press UP or DOWN key

until Quick Menu displays Unit Information icon
