Page 1 of 12 Introduction Isotempâ Laboratory and Chromatography Refrigerators Your satisfaction and safety are important to Fisher Scientific, a complete understanding of this unit is necessary to attain these objectives. As the ultimate user of this apparatus, it is your responsibility to understand its proper function and operational characteristics. This instruction manual should be thoroughly read and all operators given adequate training before attempting to place this unit in service.
Isotempâ Laboratory and Chromatography Refrigerators Installation Selecting a Location Leveling the Unit Choose a location for the refrigerator that will provide at least three inches of clearance between the cabinet and any adjacent vertical surface at the sides and rear. Appropriate electrical power must be available. Locate the refrigerator within 6 feet of the power outlet so that no extension cord is required.

The spring tension can be adjusted by moving the spring to the outside hole of the bracket or by snipping a portion of it off and then refastening it to the bracket. CAUTION: Where safety glasses before snipping spring. Shelves Shipped inside each cabinet are shelves packed in plastic and a bag of shelf supports. Two different types of shelf supports are used. The shelf supports have tab lengths of ¼ inch and ½ inch.
Isotempâ Laboratory and Chromatography Refrigerators Fig. 3 Electrical Connection Page 4 of 12 Place shelves at desired height on four shelf supports. NOTICE: Insufficient line voltage is often the cause of compressor start-up failure. It is strongly recommended that a dedicated circuit, conforming to the National Electrical Code, Article 440, be used for powering the refrigerator. CAUTION: Be sure that the power supply is the same voltage that is specified on the refrigerator’s data plate.
Page 5 of 12 Isotempâ Laboratory and Chromatography Refrigerators The customer should have the wall receptacle and circuit checked by a qualified electrician to verify the receptacle is properly grounded and meets power requirements specified on the data plate. WARNING: DO NOT under any circumstances cut or remove the third (ground) prong from the power cord. DO NOT use a two-prong adapter plug.
Isotempâ Laboratory and Chromatography Refrigerators Page 6 of 12 Begin operation by inserting the key into the key switch located on the header panel. The key switch is packed inside the envelope, which is shipped in the refrigerator chamber. Turning the key switch to the ON ( | ) position will energize the evaporator fans and the digital controller. Temperature Controller The digital temperature controller is located on the left side of the header panel (See Figure 4).
Isotempâ Laboratory and Chromatography Refrigerators Page 7 of 12 For Example: The display indicates 4°C but a reference thermometer in the refrigerator chamber indicates 6°C. The operator presses and holds the Menu keypad for 5 seconds, then changes the display value from 0 to +2 by using the UP arrow key. Press the Menu key again. Now the display indicates a chamber temperature of °6 C and the controller begins to cool (as long as 3-min.
Isotempâ Laboratory and Chromatography Refrigerators Page 8 of 12 Fluorescent Lamps The interior lamp is controlled by a rocker switch on the header panel. This light may be operated any time the cabinet power is turned on at the keyed power switch. If the interior lamp fails, replace with the same size and wattage lamp. DO NOT USE REDUCED WATTAGE LAMPS. The reduced wattage lamps generally fail to light below 60 °F (15 °C).
Isotempâ Laboratory and Chromatography Refrigerators Page 9 of 12 Trouble Shooting Table This table is intended to assist in resolving user-correctable Refrigerator problems by relating symptoms to their likely causes. If service beyond the scope of this table is required, contact Fisher Scientific Service Division @ 1-800-395-5442. Symptom Does Not Run Action Plug in Unit Blown fuse or tripped circuit breaker. Check fuse or circuit breaker at breaker box. Defrost unit. Increase Ho time.
Isotempâ Laboratory and Chromatography Refrigerators Maintenance Cabinet Cleaning Page 10 of 12 CAUTION: When servicing the unit, disconnect from the electrical power source The cabinet interior should be cleaned frequently. Any spilled liquid should be wiped off immediately. Stains resulting from some spills can be permanent if not quickly removed. The most convenient time to clean the interior is after defrosting. The cabinet exterior should be cleaned occasionally.
