INITIAL START-UP

POWER SUPPLY

￿Connect unit to power supply. Check to verify that the compressor, lamp and fans are running.

Important: Low line voltage is often the cause of service complaints. Check to see that the line voltage is within specified range with the unit running.

TEMPERATURE CONTROL

￿The temperature control knob is located inside the cabinet in the motors panel. See Figure 8. Unit is factory set at the number 4 position (normal), which will maintain the product at approximately 38F. For colder temperature, turn the black adjustment knob to a higher setting. Adjust temperature control in small increments, one position at a time.

CAUTION

Allow 24 hours between temperature control adjustments. Excessive tampering with temperature control could lead to service difficulties.
