2.4 MIX PUMP CHECK OUT
Before using, the U3-02A Mix Pump should be thoroughly
cleaned. This is necessary to remove any foreign
materials that may be present.
A. The overrun 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
bleed valve. 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
bleed valve. 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.
