Text Box: ADJUSTMENTS There are only two (2) adustments which can be made to the machine, Water Purge and Ice Thickness. WATER PURGE Water purge should be set at approximately 5-10% of the weight of ice per cycle (Check specifications chart on page 1 for recommended amount) As the water purge is time activated, it will vary with water pressure. Up to and including Version 4.1 Logic Board To check the water purge, hold a measuring cup under the overflow hose and catch the waste water at the end of the fill cycle. The cup should be held there for at least five (5) minutes as the waste water may take some time to stop running. The purge adjustment is located on the control panel just above the fault light. Adjustment is made using a small screwdriver to turn the adjusting screw anti-clockwise to increase or clockwise to decrease as indicated. Version 5 Logic Board To check which version board the ice machine has fitted, simply turn the power off and then on at the power point. The unit will beep a number of times. eg 4 beeps = V4, 5 beeps = V5 This happens every time the machine is turned on. To check the water purge place a measuring cup under the overflow hose and catch the waste water at the end of each fill cycle. The cup should be held there for at least five (5) minutes as the waste water may take some time to stop running. The purge adjustment is set through the buttons on the logic board. With the machine in two (2) mode, press and hold the reset button and then a number will flash which will indicate the setting of the purge time 0 to 9. 1 being 1 second, 9 being 9 seconds and O being 10 seconds. By pressing the fill button this will change the setting to obtain the correct purge amount. Once you let the reset button go, it will return to two (2) mode. Note: This function only works during freezing cycle. The purge should be checked at least 3 times. A quick way to check this is by removing panels and having the machine in number 2. Drain water trough by removing drain plug until the machine goes into defrost mode. Replace drain plug and open and close each water curtain, this will now put the machine into fill mode. Once again check the purge amount and if required make purge adjustment. Repeat this at least twice to verify the purge amount. ICE THICKNESS The correct weight of ice per cycle has been factory set with the machine LEVEL and the correct purge. If the machine is not installed level this can alter the weight (size) of the ice. NOTE: Refer to specification chart on page 1 for correct ice weights. Adjustments are made by moving the adjustable float up or down. The adjustable float is located at the water pump end of the trough. To make the ice thicker i.e. heavier, loosen the brass thumb screw and lower the float. To make the ice thinner i.e. lighter, raise the float. When making any adjustments, it is recommended that you only move the float 1mm to 2mm a time. After making any adjustments, tighten the thumb screw to ensure the float cannot move.
