Fig. 3 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.

The frequency and nominal voltage requirements for the unit are specified on the data plate, which is located on the interiors upper left side. Only plug the unit into a power source that meets these requirements. Low line voltage is often the cause of service complaints. With the unit running, check that the line voltage is within ±10% of that specified on the data plate.

WARNING: For personal safety this unit must be properly grounded.

The power cord of this instrument is equipped with a three prong (grounding) plug (NEMA 5-15P). This plug mates with a standard three prong (grounding) wall receptacle (NEMA 5-15R) to minimize the potential of an electrical shock hazard. Chromatography models are equipped with a (NEMA 5-20P). This plug must mate with a (NEMA 5-20R).
