Page 4: Introduction
One Cornelius Place Anoka, MN 55303 1–800–554–3526 The warranty on Cornelius icemakers begins on the date of installa- tion, as reported on the warranty registration card to the original owner/user. If no warranty card is received by the factory, the date of shipment from the factory will determine the start of the warranty. -

Page 41: Dump Cycle Options
Dump Cycle Options You have the option of selecting dump cycle intervals of: every cycle; (Standard setting from factory) every 3rd cycle; every 5th cycle; every 7th cycle. Remember, the higher the mineral content in the water supply the more often it will be required to dump the water and/or clean the product if proper water treatment is not used. -
Page 42: Condenser Fan Cycling Control (Intergal Condenser)
Condenser Fan Cycling Control (Intergal Condenser) The condenser fan on air-cooled cubers is cycled by the circuit board. The condenser sensor signals the circuit board when the con- denser temperature reaches 100°F (38°C) the fan starts and contin- ues to run until the temperature is reduced to 88°F (31°C). NOTE: There is no pressure control used to cycle the fan motor on Intergal Air Cooled Condenser Units. -

Page 45: Evaporator Switches
Should sensor (thermistor) pass the voltage test pro- ceed to the control board diagnosis for LED sequence (see page 39). NOTE: The sensor controls the condenser fan cycling from 88/100 degree Fahrenheit. Thus any defects in the condenser circuit will effect the fan cycling rate. Evaporator Switches Proximity Switches are half mounted to the water curtain, and the other half mounted to the evaporator side rail. -
Page 46: High Pressure Safety Switch
Should adjustment be required, the valve has an adjustment stem on the top of the valve. After allowing the cuber to operate for 10 min- utes in the ice making mode to balance the system, turning the ad- justing stem CW will increase the discharge water temperature, and CCW will decrease the discharge water temperature. -

Flow control washer flat side up Service Stem Valves When closing the service stem valves to remove your gauge and manifold set always close the high side stem valve first. Following this procedure will allow the system to “PULL” the refrigerant vapor from your manifold set to reduce refrigerant loss. -

Page 49: Head Pressure Control Valve
70°F by-pass The Cornelius “I” series remote systems use an Alco Head Pressure Control, normally referred to as a headmaster. This control is mounted in the remote condenser with a fan cycling control switch. Using both these controls gives the system positive operation under a wide range of condensing temperatures. -

Page 53: Moisture Contamination
Compressor mechanical problems Low Refrigerant Charge Moisture Contamination With the major changes in refrigerants in today’s marketplace and the use of hydroscopic oils the control of moisture and contaminates have become more critical to safeguard against than ever before in the history of mechanical refrigeration. - Page 54 Readings in the range listed below 100 Meg–Ohm would be an indi- cator that the system being tested may have a contamination prob- lem. Where does the problem come from? As an example, the filter drier may become saturated and hold large percentages of moisture and the system function without a problem until such time as the product operating conditions change.
