Page 5: Installation Instructions
INSTALLATION INSTRUCTIONS You will get better service from the ice machine, longer life and greater convenience if you choose its location with care. Select a location as close as possible to where the highest volume of ice will used. Here are a few points to consider: 1. -
Page 6: Figure 2. Service Connections
10. The incoming water for the ice making section requires a 3/8” copper tube. Connect this water tube to the 3/8” male flare fitting on the back of the unit. Make all drain connections. Drain tubes cannot be teed together. See Figure 2 for location of all plumbing connections. NOTE: For water cooled units, a separate 3/8”... -

1. Remove the chute from the evaporator assembly 2. Remove item 1, .50-20 x 1.25 bolt; item 2, .50 lockwasher; item 3, ice paddle, and item 4, flaker cutter head. 3. Install item 5, nugget ice cutter head, and re-install items 1, 2, & 3 4. -
Page 8: Water And Ice Circuit
WATER AND ICE CIRCUIT The supply water enters the float chamber through a small orifice. The water level rises and lifts the float arm on the float valve and seats the valve, shutting off the water supply when the water is at the desired level. As the water leaves the float chamber, filling the evaporator, the float drops and allows additional water to enter refilling the float chamber. -

“I” SERIES FLAKER CLEANING AND SANITIZING PROCEDURE 1. To eliminate water from entering the reservoir, block up the float located inside the reservoir, activate the dump switch to the “ON” position and turn the power switch to “ON”. Allow the evaporator to drain. Turn the power switch to the “OFF”... -

Page 17: Installation Instructions Remote Condensers
The condenser fan may cycle off during the harvest cycle – this would be normal. Note: Installing an IMI Cornelius remote flaker with other than an IMI Cornelius remote condenser and line set may be reason to void the warranty. - Page 18 4. Each condenser and flaker is connected with two (2) *pre- charged lines. a. The pre-charged lines are ordered separately from the condenser to suit each individual application. b. The pre-charged line lengths are 20 feet [6.096 meters], 35 feet [10.66 meters] and 55 feet [16.76 meters]. Note: *(Pre-charged is defined as a vapor holding charge –...

- Page 21 will not be necessary (refer to illustration). However, when shortening or lengthening is required, do so before connect- ing the line-set to the ice machine or the remote condenser. This prevents the loss of refrigerant from the ice machine or the condenser.

Page 22: Head Pressure Control [Headmaster]
Head Pressure Control [Headmaster] 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 23: Remote System Evacuation/Re-Charge
Remote System Evacuation/Re-charge All field repairs to the sealed system must start with a total dis- charge of the system following the requirements of the Clean Air Act of July, 1992. Proper evacuation of the total remote system will require a three (3) point hook-up of your manifold and hose set, (see drawing): Point #1 - flaker receiver outlet valve Point #2 - flaker high side service valve... - Page 24 2ND STAGE CHARGING 1ST STAGE CHARGING EVACUATION COMPRESSOR OPERATING MANIFOLD SET MANIFOLD SET OPEN OPEN MANIFOLD SET OPEN CLOSED CLOSED OPEN OPEN CLOSED CLOSED RECEIVER RECEIVER HIGH SIDE HIGH SIDE RECEIVER HIGH SIDE SERVICE SERVICE SERVICE VALVE VALVE VALVE OPEN OPEN CLOSED SIDE...
- Page 25 4. *After proper evacuation hold test has been performed, the refrigerant charge should be “dumped” into the receiver until the pressure equalizes, stopping the flow. Do not try to throttle the refrigerant flow. Doing so will allow system pressure to balance too soon. The high-side service valve should be closed and the balance of the charge fed slowly through the suction side service valve with the compressor operational.
