10. Connect free end of mix pump hose to "4 way Tee"
     as shown in Figure D.  When all connections are
     complete the "4 way Tee" must be lower than the
     black pump housing.

C. Connect 1/2 inch (1.27 cm) I.D. plastic food grade

tubing to the check valve and then to the mix con-
tainer. Observe check valve flow arrow. Secure with
hose clamps.

D. Connect 1/2 inch (1.27 cm) ID plastic food grade

tubing between the large port of air/mix tee and
refrigerated mix transfer line. Secure with large hose
clamp or equivalent.

CAUTION

AIR/MIX TEE MUST REMAIN BELOW THE BLACK
COVER/CLAMP. IF THE TEE IS ABOVE THE PUMP  MIX
WILL DRAIN TO THE AIR COMPRESSOR RESULTING
IN PUMP DAMAGE.

PUMP MUST BE PLUGGED INTO A PROPERLY
GROUNDED ELECTRICAL RECEPTACLE WITHOUT THE
USE OF A GROUND ADAPTER PLUG.

2.4  MIX PUMP CHECK OUT

Before using, the U3 Mix Pump should be thoroughly
cleaned. This is necessary to remove any foreign
materials that may be present.

A. The over-run adjustment is preset at the factory.  If an

adjustment becomes necessary, refer to Section 4.1.

B. Check for air leaks by placing the suction line into

two gallons of cold water. Place the freezer switch in
the OFF position. Close the spigot and freezer air
vent. Place mix pump switch in the ON position and
allow the system pressure to build up and pump to
shut OFF automatically. Leave the pump on for ten
minutes.

During this time, do not open spigot or freezer air
vent.  If pump does not automatically start again
during this period, the system is free of leaks.  If the
pump does start, there is a leak in the system.
Locate leak by applying a liquid detergent or bubble
solution with a small brush to all tubing connections
and o-ring seals. Correct as required.
