This unit makes ice at -10 degrees Fahrenheit and stores it at 2D degrees Fahrenheit. Prior to serial #301252, this equipment used our control $3-01-238-0. After serial #301252, we utilize our control #3-01-244-0. At a #7 setting the cut-out temperature will be about -5 degrees Fahrenheit and the cut-in will be 5 degrees Fahrenheit. At the #1 setting, the cut-out will be 5 degrees Fahrenheit and the cut-in will be 15 degrees Fahrenheit. Changes to be aware of relative to this equipment are listed as follows: Charge - Use 6.5 oz.

Sub-Zero has redesigned the model #22IM undercounter automatic icemaker. These units are The new design now in production and will be introduced to the field in the near future. became effective as of Serial #509241. We have incorporated a larger back wall evaporator while eliminating the secondary evaporator pass under the icemaker. This new coil is designed to run at a -20 degrees Fahrenheit coil temperature versus the old coil, which ran a -10 degrees Fahrenheit. The refrigerant flow starts at the compressor to the condenser, around the hot gas gasket loop through the cap tube to the evaporator coil and returning to.the compressor by way of the heat exchanger. The inside air is pulled in from the The air flow is consistent with our previous design. bottom behind the evaporator cover and over the evaporator coil. The chilled air is then discharged over the top of the icemaker and is returned to cool the ice storage bucket to a 0 degrees Fahrenheit storage temperature. The thermostat sensing is taking place at the top edge of.the icemaker mold this senses a At a normal #4 control setting, the combination of cold temperature and air temperature. thermostat cuts out at -9 degrees Fahrenheit and cuts in at +6 degrees Fahrenheit with a cut-out pressure of 0# PSIG and a cut-in pressure of 12# PSIG. We have changed the electrical system; the wiring diagram (see page ) shows the addition of a drain tube and drain trough heater with both heaters remaining on for the This diagram will also show the removal of the time delay duration of the defrost cycle. relay. The relay split our wiring system between the compressor (run) and the icemaker (harvest). This allowed the icemaker to harvest only during the off cycle of the compressor with a six minute delay built into the relay so as to complete the harvest before the compressor could restart. With this new design, we have wired the icemaker direct. This allows the icemaker to harvest when the mold is satisfied.

The bottom door hinge cam (right or left swing) is identified by part #3-42-069-0. The bottom cabinet hinge is identified by part #3-42-068-1 for right hand swing and #3-42-068-2 Please be aware that if the screw holding the cam for left hand swing. assembly becomes loose, it may be necessary to use some loctite #371 (part #619-023-0) to assure a tight fit.
201 FIELD DOOR CLOSER KIT Over the years, we've received complaints on these large doors bouncing open due to the size and the weight of the doors. Because of this, we have established a gravity type door closer kit, which can be used to eliminate this problem. This kit, #4-20-023-0 (right hand) and #4-20-024-0 (left handJ can be used between serial #234227 and #338384. These kits are not covered as a warranty item, but are considered a field accessory and can be purchased through your Parts Distributor. Beginning with serial #338385, this closer is a factory standard. UNDERCOUNTER DOOR CLOSER KIT Beginning with serial #356747, undercounter models 244RFD and the entire 249 series will have door closers. This door closer is similar to those used on built-in units, except that it is mounted on the side of the base. For units prior to serial #356747 an "add-on" door closer kit is available These door closers are the same type which is through your Parts Distributor. There are two now incorporated on the undercounter 244 and 249 models. different kits avilable; part #4-20-026-0 for right hinged units and part #4-20-027-0 for left hinged units. Please be aware that the "add-on" door closer kits ARE NOT a warranty item, but an accessory. All units built after serial #356747 will have the closer installed. UNDERCOUNTER DOOR SWING CHANGE KIT With an increasing demand for left and right handed hinged products we have made both products available. Therefore, beginning with shipments dated after 5-18-84 the following swing change kits are available at a charge to the customer. To change the swing frotn right to a left swing order part #4-20-025-0; left to right swing order part #4-20-025-1. Also, if after the kit has been installed, a door adjustment is necessary, it IS NOT covered by the factory warrranty.

2011 ICE DOOR ASSEMBLY If the freezer door (part #4-18-073-0) needs replacement, it is NOT necessary to replace the complete icemaker sleeve assembly (part #4-20-038-0). Please be aware that the rivits that connect the door hinge to the sleeve base are just for manufacturing purposes. If the rivi-ts break loose, the door still remains intact and secured by the (2) two bottom screws (part #6-20-0540) that hold the sleeve in place. In the event that the door requires replacing (i.e. because of a cracked liner, warped door, etc), the defective door and hinge assembly must be removed by first removing the support screws and then pulling the rivits out* At that point, the new door and hinge assembly can be installed between the freezer sleeve and the interior base and secured by replacing the (2) two support screws. ICE OR ICICLE FORMATION IN FREEZER DOORS A situation could occur where air penetrates the seal between the foamed door slab and the back side of the gasket causing moisture to build up on the The doors are manufactured in a way to inside of the freezer door liner. prevent this by tightly securing the metal gasket retainers to the door with the gasket acting as the sealer.
If the door wasn't adequately sealed at the factory, the following is what to look for.
Situation: With freezer door open for an extended period of time water will drip from the bottom freezer door hinge, Remedy: Remove door liner, gasket and retainers. Apply a bead of silicone Also approximately 3/16" diameter around the perimeter of the door shell. silicone around the bolts that secure the shelf ladders to the door liner. Reinstall gasket, liner and retainers making sure the seal is adequate between the back side of the gasket and the door shell (make sure you are sealed around the complete door). SWEATING AROUND THE FREEZER DOORS
In the event there are periods of high humidity (exceeding 86% relative humidity), some moisture could appear. This condition will exist for short periods of time and will dissipate with a lower humidity. This particular This condition occurrence is true with most types of refrigeration equipment. can also be attributed to the door not sealing properly or some item in the unit propping the door open, keeping it from sealing properly. If the unit is installed in an area of continuous high humidity, please refer to page 7-8.
CRISPERS FALLING OFF TRACKS
If this does occur, please note the amount of the crisper may be prevalent. "flange" or edge that comes in contact with the crisper rollers on the slides, The flange should rest on the full width of the roller. If not, the crisper
If a situation occurs where the crispers have a tendency of falling off when removing them from the refrigerator section, a spacing or alignment problem
