8. Different water valves have different flow rates For this reason anytime a water valve is replaced the water fill must be checked and the fill switch must be adjusted if needed The correct water fill volume is 80 to 100 cc To measure the fill volume test cycle the Ice Maker and collect the water Measure in a container calibrated in cubic centimeters CC the fill time is 5 0 seconds The fill volume is adjusted by increasing or decreasing the length of time the water fill switch remains closed To adjust the water fill switch first determine how much water is needed The adjusting screw is calibrated so that one complete revolution changes the water fill about 18 cubic centimeters Turning the screw clockwise decreases the fill while turning counterclockwise increases the fill EXAMPLE An ice maker is test cycled and the water fill sample is 93 cubic centimeters Subtracting 80 cc from 95 the adjustment needed is 13 cc Since one turn of the adjusting screw changes the fill 18 cc 34 of a turn clockwise would reduce the fill about 13 cc the desired amount This example is for manual models only 7 3 Section 7 Ice Maker Parts Replacement Disconnect electrical supply to refrigerator To Replace Front Cover Figure F4 1 Remove ice maker from freezer 2 Ensure that ice maker is at room temperature before removing Cover 3 Remove screw at the top of the cover and tip it out until the tab at the bottom

A two stage pump can reach a deeper vacuum than a single stage because the exhaust from the first pumping stage is discharged into the second pumping stage This means the second stage begins pumping at a lower pressure so a lower ultimate vacuum can be achieved See 2 Stage Vacuum Pump Figure E3 2 Stage Vacuum Pump Figure E3 Vacuum Pump Maintenance It is absolutely essential to maintain your vacuum pump according to the manufacturer s instructions including required oil changes at the recommended intervals Vacuum pump oil should always be changed after evacuating a contaminated system Vacuum pump performance should be checked periodically with a micron gauge Vacuum pump suppliers may or may not recommend changing the vacuum pump oil to the same type that s in the system being evacuated Some manufacturers may recommend a vacuum pump that s dedicated to R 134a systems Robinair has stated that their current and discontinued vacuum pump models using mineral oil currently specified for use in their vacuum pumps can be used to evacuate R 134a Ester oil systems Robinair also states that it is acceptable to alternate between evacuating R 12 mineral oil and R 134a Ester oil systems without adversely effecting the vacuum pump s performance For other brands of vacuum pumps check with the manufacturer for restrictions and guidelines when using with R 134a 6 17 Section 6 Refrigeration System CAUTION

31. If you use a vacuum pump with mineral oil to evacuate an R 134a system it is ABSOLUTELY ESSENTIAL to have a shut off valve between pump and your manifold gauge set as shown in Figure E2 The hand valve must be closed during all times when vacuum pump is not operating This will prevent migration of mineral oil vapor into R134a Ester oil system If vacuum pump should stop during evacuation for any reason the hand pump shut off valve must be closed immediately Refrigerant Leaks A system with R 134a and Ester oil will become saturated with moisture much faster than a system with R 12 and mineral oil If your leak was in the low side of the refrigeration system when the compressor is running the pressure in the low side will go into a vacuum As additional refrigerant leaks out the system will go deeper into a vacuum The system running in this vacuum will allow air and moisture to be pulled into the sealed system The moisture pulled in can then be mixed in to the Ester oil in the compressor If the product has had a low side leak you will need to install the two stage service dryer filter part number 5303918288 You must heat the crankcase area of the compressor using a heat gun on the high heat setting though out the 30 minutes you are running your vacuum pump to pull a vacuum on the system Every 4 to 5 minutes while you are running your vacuum pump and heating the crankcase area shake the compressor By heating the crank case you are
