INITIAL START UP, CHECKS AND ADJUSTMENT INSTRUCTIONS

NOTE: Do not start Icemaker before completing installation steps on pages 7 and 9.

Turn on water supply (if Icemaker is water cooled turn water on to condenser also) turn on main power switch (located on top of electrical box), and make the following system checks:

NOTE: If Icemaker will not start be sure water reservoir is full. Low water safety control must be prop- erly adjusted to start and shut down the Icemaker. If water level drops below bottom of reservoir, the Icemaker must shut down. Adjustment is made by moving magnet up or down.

Water Level—If necessary adjust float by bending float arm up or down as needed, push float assembly down until Icemaker stops running. Release float and Icemaker will restart. Keep water in reservoir at level line while the Icemaker is in operation. See Figure 3

Low Water Safety Control—Adjust magnet by bending magnet arm as needed to shut unit down if water level drops below bottom of reservoir.

Bin Control—Place ice around probe, unit should shut down in one minute. Remove ice from around probe, unit should start in two minutes.

NOTE: For altitudes over 1000 feet above sea level, adjust range screw (behind end cover). Half turn max. raises setting 4_F approx.

Water modulating valve (water cooled units only)—Opening point of condenser water modulating valve should be set to maintain proper operating pressure in the refrigeration system high side. (see chart on page 13). Closing point of valve should be set low enough to close valve during compressor stand by periods. To raise, turn counterclockwise, to lower turn clockwise.
