FINALIZING THE INSTALLATION
1.
Push the grille back into place . This will attach the grille
to the ball studs .
2.
Screw in the eight screws to secure the front access
panel .
Evacuation
•
Remove the nitrogen tank from the manifold and attach the manifold to the refrigerant tank .
•
Install a micron gauge on the access valve near each evaporator unit .
•
Mid-seat both service valves .
•
Install service caps on the valves .
•
Energize the liquid line solenoid valve .
•
After confirming that there is fresh oil in the vacuum pump, connect the 3/8” hose from the manifold to the pump .
•
Start the pump and run it until the micron gauge on each evaporator unit reads 200 microns or less .
•
Disconnect the vacuum pump from the system .
•
Break the vacuum with R-404a refrigerant .
•
Remove the micron gauge from the access valve .
Charging
•
Install a low-pressure gauge on the access valve near each evaporator unit .
•
With the power off to the condensing unit, admit liquid refrigerant through the liquid line service valve until the refrigerant
stops flowing .
•
Turn on the circuit breaker for the condensing unit . The compressor should turn on if the pressure in the suction line is above
20 psig .
•
Add refrigerant and observe the sight glass . If bubbles are present, add more refrigerant until the sight glass is clear .
•
Once the sight glass is clear, check the superheat at the outlet of each of the evaporator units . Adjust the TXV until the
superheat is between 8-12°F degrees .
•
Under normal operation, with the wine cellar at 55°F and the ambient temperature at 85°F, the low side pressure should be
between 78-82 psig and the high side should be between 300-330 psig .
Finalizing the Installation
•
Confirm that the entire suction line from the TXV to the suction line service valve is insulated using cellular insulation or
equivalent . Seal all seams with Armaflex 520 foam insulation adhesive or equivalent .
•
Confirm that the control is displaying the correct temperature and that no alarms are present . Refer to page 41 for corrective
action if alarms are present .
