Step 5
Evacuate the field constructed refrigerant lines using
theacc ess fittings brazed on the condensing end of the
refrigeration lines.
Step 6
When the evacuationprocess is complete, relieve the
vacuum with 4 oz. (113g. ) of HP62 refrigerant per line,
for a total of 8 oz. ( 227 g.) This procedure will prevent
moisture contamination during dispenser and
condensing unit connection and complete the total
charge.
Refrigeration Connections
Connect the refrigerant line quick connect/disconnect
couplings to the mating quick connect/disconnect
couplings on the dispensing and condensing unit.
Step 1
Remove the shipping caps from the quick
connect/disconnect coupling on the dispensing unit.
Step 2
Thoroughly clean and lubricate the mating surfaces of
the quick connect/disconnects.
Note: Use polyolester oil to lubricate the surfaces.
Step 3
Manually thread the coupling halves together to insur e
proper mating of the threads.
Step 4
Using proper sized wrenches, tighten the coupling
halves until the round, flat surfaces of inner coupling
bodies completely depress one another.
Step 5
Once the flat surfaces are completely depress ed,
tighten the couplings an additional 1/4 turn. This step
is necessary to insure that the knife edge of the s eal
seats into the brass seat of the coupling halves,
forming a leak-proof joint (metalseal).

Step 6
Check all connections for leaks.
Step 7
Insulate all exposed suction line tubing and fittings.
Step 8
Set the pump down switch located in the c ondensing
unit. For indoor condensing unit application:
Set cut in at 30 PSIG (207 kPa).
Set cut out at 5 PSIG (34 kPa).
For outdoor condensing unit application:
Set cut in at 20 PSIG (138 kPa).
Set cut out at 0 PSIG (0 kPa).
Pump down pressure readings are to be taken at the
refrigeration line access fittings at the condensing unit.
Step 9
Allow the dispenser to run until the condensing unit
cycles off. Verify the proper pump down pressure
switch setting. See Step 8 of “Ref rigeration
Connections” (page 4).
Note: Pump down pressure readings are to be taken
at the refrigeration line access fittings near the
condensing unit.
Step 10
If necessary, adjust viscosity to produce satisfactory
product. Adjustments are made by turning the
viscosity adjustment screw (located under thecontrol
panel) clockwise for a thicker product or
counterclockwise for a thinner product.
Set Up Procedures
Standard Fill Module
Step 1
Connect the product supply line to the 1/4” barbed
fitting on the fill solenoid. Adjust the fill system
pressure to deliver product to the hopper at
approximately 15 to 20 PSIG (103-138 kPa).
Step 2
Lubricate, assemble, sanitize and prime t he dispenser
as outlined in the Assembly section of this manual.
Step 3
Place the power switch in the “AUTO” position.
Note: The fill switch must be in the “ON” position to
enable refrigeration.
