PrefaceImportant installer and user information:A redundant temperature sensing device has been included in this ULT freezer. Thisdevice is a type “T” thermocouple. For convenient access, the thermocouple (Figure 13) terminates in an interconnect jack (Figure 1-5) behind the base front cover. (May belocated differently in chests. See Section 1.) It is strongly recommended that this thermocouple be attached to a redundant 24 hour 7 day monitoring system with alarmcapabilities. Connecting the sensor to a monitoring and alarm system separate from thefreezer provides the utmost in product safety, should the integral system fail. sPacking ListPart No.DescriptionQty213FKey2380520Neoprene Cap25100161/4-20 x 5-1/2” Bolt2195763Retaining Clip1370563Remote Alarm Connector1-86C Models Covered-40C Models CoveredNumberModelCu. ft.Voltage/HzNumberModelCu.

Remove the ramp boards from the palletand place the slotted end over the ramp brackets on the pallet. Thesupport blocks on the ramps will be facing down. Before moving thefreezer, make sure the casters are unlocked and moving freely. Align thecaster with the ramp boards. Use adequate personnel to roll the freezer offthe pallet.The freezer can be easily pushed to the desired approved location, asdescribed previously. When the freezer is in position, set the front casterbrakes.Note Do not move the freezer with the product load inside. sThermo Scientific8600 Series1-7
Section 1Installation and Start-upChoose LocationLocate the freezer on a firm, level surface in an area with an ambienttemperature between 18 C and 32 C. Provide ample room to reach themains disconnect switch (power switch) located on the rear of the freezer.Note For proper ventilation and airflow, a minimum clearance of 5” at therear and front and a clearance of 8” on the side of the freezer is required.Allow adequate space for lid opening. If ambient increases above 36 C,clearance at the rear of the cabinet must be increased to 8”. sInstall Wall BumpersThe parts bag, located inside the cabinet, contains the following parts.QuantityStock #DescriptionPurpose25100161/4-20 x 5-1/2” BoltWall Bumper2380520Neoprene CapCap ProtectorInstall the bolts into the pre-tapped holes on the back of the compressorsection. Install a neoprene cap on each bolt. Refer to Figure 1-2 for thelocations of the pre-tapped holes.RS-232 Communications8600 Series freezers have a data communications interface. The factorydefault setting is RS-232.The wiring identification for the interface isshown in Figure 1-10. One nine pin, sub"D" style connector is located on the backof the freezer. See Figure 1-2 for thelocation of the connector on the freezer.Figure 1-10. RS-232 InterfaceThe freezer transmits temperature information every 60 minutes.

The remote alarmconnector is located in the parts bagprovided with the manual. It mustbe installed if connecting the freezerto an alarm system. After installing Figure 1-11. Remote Alarm Contactsthe wiring from the alarm system tothe connector, install the connector to the freezer microboard and securewith the two screws provided. The remote alarm provides a NO (normallyopen) output, a NC (normally closed) output and COM (common). Thecontacts will trip on a power outage, high temperature alarm or lowtemperature alarm. They will also trip on high stage (-86C units only),control probe and microboard failures. Figure 1-11 shows the remotecontacts in alarm state.8600 Series1-9
Section 1Installation and Start-upRemote Alarm Contactsand Analog Output (cont.)The analog output function allows thefreezer to output signals representingthe temperature of the freezer cabinet.The factory default setting is 4-20 mA.Refer to Table 1-2 for outputspecifications.IMPORTANT USER INFORMATIONCAUTION! Stored product should be protectedby a redundant 24 hour/day monitoring systemwith alarm capability. An interconnect jack andthermocouple are installed for centralizedmonitoring, should on-board system fail.Table 1-2. Analog Output SpecificationsTemperatureAttach Power Cord4-20 mA0-1V0-5V-100 to 50 C-100 to 50 C-100 to 50 CInsert the power cord into the power inlet module. Place the retainingbracket (P/N 195763) over the connector. Tighten retaining screws tosecure.Figure 1-12. Power Cord AttachmentConnect Unit to ElectricalPowerNote See the serial tag on the side of the unit for electrical specifications orrefer to the electrical schematics in this manual. sThe freezer should be operated on a dedicated, grounded service. Checkthe voltage rating on the serial tag of the unit and compare it with theoutlet voltage. Then, with the power switch turned off, plug the line cordinto the wall outlet.First, turn on the freezer power switch. Then open the lower front door bygrasping the bottom left corner. Locate the battery switch (Figure 1-4) andturn it to Standby mode ( ). During initial freezer start-up, the systembattery may require charging and the Low Battery message may appear inthe message center.Note Ensure the battery switch is turned to Standby mode ( ). Therechargeable batteries require 36 hours to charge at initial start-up. A “LowBattery” alarm may occur until the batteries are fully charged. Should apower failure occur during the initial start-up period, the electronics willhave limited operation. s1-108600 SeriesThermo Scientific
Section 1Installation and Start-upFreezer Start-UpWith the freezer properly installed and connected to power, system setpoints can be entered. The following set points can be entered in Settingsmode: Control temperature, high temperature alarm set point, lowtemperature alarm set point, and (optional) BUS set point. Defaultsettings are shown in the table below. See Chart 1-1 for more detail.-86C Units-40C UnitsControl Set Point-80 CControl Set Point-40 CHigh Temperature Alarm-70 CHigh Temperature Alarm-30 CLow temperature alarm-90 CLow temperature alarm-50 COptional BUS Set Point-60 COptional BUS Set Point-30 CNote If the set point is changed and the low temperature and hightemperature alarms are set 10 from the set point, the alarm set points willbe adjusted automatically to maintain a distance of at least 10 from setpoint. sSet OperatingTemperatureThe freezer has an operating temperature range of -50 C to -86 C (-86Cunits) or -10 C to -40 C (-40C units), depending on ambienttemperature. The freezer is shipped from the factory with a temperatureset point of-80 C (-86C units) or -40 (-40C units). To change theoperating temperature set point:1. Press the Mode key until the Settings indicator lights.2. Press the right arrow until “SET PT -XX” is displayed in the messagecenter.3. Press the up/down arrow key until the desired temperature set point isdisplayed.4. Press Enter to save the set point.5. Press the Mode key until the Run indicator lights for Run mode orpress the right/left arrow keys to go to next/previous parameter.If no control keys are pressed, the freezer will automatically return to RUNmode after 5 minutes.Thermo Scientific8600 Series1-11
