Introduction Section 1 Fisher Isotemp 600 Series Standard incubators are available in three sizes: Small, Medium and Large. All incubators provide PID microprocessor control at operating temperatures ranging from 30 (86°F) to 75°C (167°F). Note Ambient temperature must be at least 5°C below operating temperatures.
Fisher Scientific Isotemp® Incubators are shipped in a single carton. After unpacking, locate each item shown in the list below. Report any missing items, by name and part number, to your Fisher Scientific distributor. In the event of shipping damage, retain the carton and packing material and file a claim with the final carrier.
5A for all incubators. If the current limit is exceeded, the circuit breaker will trip. For safety, the integrity of the electrical ground should always be maintained. Isotemp Standard Incubators Fisher Scientific...
Alarm Indicator Lights if the actual incubator temperature exceeds the alarm temperature. The alarm temperature is factory-adjusted to be 5°C above the set temperature. Program Indicator Lights when the control temperature is being set. Fisher Scientific Isotemp Standard Incubators...
Pressing the SET Key causes the display to show the set temperature. Used with INCREASE Key and DECREASE Key to change the set temperature. With MENU Key to access entry of a temperature display offset (calibration feature). Isotemp Standard Incubators Fisher Scientific...
Note Upon initial heat up to temperature, the over range alarm indicator light may illuminate briefly (several minutes) until the temperature stabilizes at the set point. The incubator temperature should be allowed to stabilize prior to loading samples. Fisher Scientific Isotemp Standard Incubators...
40 and the unit went into alarm. The researcher, knowing this was a normal operation, allowed the unit to cool and stabilize at 40°C. Just below 43°, the unit alarm LED went off and the display resumed normal operation. Isotemp Standard Incubators Fisher Scientific...
The displayed temperature is the result of algebraically adding the actual temperature to the offset value. Thus, if an offset value of –3° is being used, a measured temperature of 50° will be displayed as 47°. Fisher Scientific Isotemp Standard Incubators...
2. During cleaning, take precautions to prevent cleaning agents from contacting electrical components. 3. Use a mild, non-abrasive cleaner (i.e. damp cloth and mild soap) to clean all normally accessible surfaces. 4. Make sure unit is dry before re-connecting to power source.

Section 6 Service Replacing the Door Isotemp 600 Series incubators incorporate a durable, silicone door gasket to minimize heat loss. Should the gasket become defective or be damaged, Gasket it may be replaced by following the procedure below. Note Study the method of door gasket attachment before starting disassembly.
6. Install replacement heater and reassemble unit by generally reversing the steps above. Bezel Screws Controller and relays inside bezel Heater Cover Screws Figure 6-1. Locations Heater Cover Fisher Scientific Isotemp Standard Incubators...
8. Lift out the solid state relay. Put new solid state relay in place, making certain that the thin, conductive pad remains between the solid state relay and the bezel. 9. Generally reverse the steps above to reassemble incubator. Isotemp Standard Incubators Fisher Scientific...
Remove thermocouple from clip. 8. Pull thermocouple forward into chamber, exposing roughly a 6 inch section of the thermocouple wire. 9. Cut the thermocouple wire to remove the thermocouple sheath. Fisher Scientific Isotemp Standard Incubators...
For thermocouples, the red wire is negative and yellow positive. Replacing the Glass The Isotemp 600 series incubators feature a glass, inner door to allow the Door chamber to be viewed with minimal heat loss. Should the glass door become damaged, it may be replaced by following the procedures below.
5. Secure cam tongue in place by tightening outside nut. 6. Repeat Steps 1 thru 5 as necessary to get desired door seal. 7. Secure latch cover in place with two screws. Fisher Scientific Isotemp Standard Incubators...
