Water Valve allow adequate time for the pressure to stabilize. Important: On the Models 336 and 338, expansion On a water cooled unit, the water valve should be set to valves on each side of the unit must be set separately.
Generation II Control Logic Board The Generation II logic board's primary function is to interpret As of July, 1996 we have modified the differential on modes of operation. The board monitors mix levels and Generation II controls from 13'F/7.2'Cto4.5'F/2.5-C in order temperatures by sending commands to the control's power to meet the new NSF mix temperature requirements.

When checking a thermistor probe, first determine the present temperature at the probe and find it on this chart along with the approximate correct ohmmeter reading.
Service Tips for Generation II Boards Initial Service Tips 1. Check all connections. 2. Check the cable to verify that it is secure. 3. Verify that all pins are securely fastened in their sockets. 4. Verify that all cables correctly face away from the boards.
