Step 8:
Connect the electrical box on
the condensing unit to a power source
as shown in the attached figure. The
condensing unit is rated for
208/230V-1-60.
VDPTCU005 = 21.6A MCA
VDPTCU006 = 14.9A MCA
Step 9:
a.) Confirm that the unit is free of leaks using pressurized nitrogen at approximately 150 psig and then
pull a vacuum down to 200 microns for at least 30 minutes.
b.) Charge the unit with 3 lbs. of R404a into the receiver. Break the vacuum on the low side prior to
starting the unit.
c.)
Turn ‘ON’ the power to the condensing unit and the display case. Turn the display case ‘ON’. The
high side pressure should be approximately 30°F above the ambient temperature. Add refrigerant if
needed.
d.) Set the low pressure switch to 40 PSIG with a differential of 30 PSIG.
e.) Wait for at least 1 hour prior to placing product in the unit.
