EQUIPMENT SAFETY Your safety and the safety of others are very important. We have provided many important safety messages in this manual and on your unit. Always read and obey all safety messages. This is the Safety Alert Symbol. The symbol alerts you to potential hazards that can kill or injure you and others. All safety messages will follow the Safety Alert Symbol and either the words "DANGER" or "WARNING".
the cooling system are damaged. leaking coolant can ignite and may damage the eyes. In the event of any damage: - Avoid open flames and anything that creates a spark, - Disconnect from the electrical power line, - Air the room in which the unit isolated for several minutes, and - Contact the Service Department for advice. • The more coolant there is in a unit, the larger the room it should be installed in.
INSTALLATION INSTRUCTIONS Before using your equipment • Remove the exterior and interior packing. • CAUTION: After unpacking you MUST allow this unit to stand upright for at least 2 hours to allow the lubricant and refrigerant to drain back into the compressor and stabilize. Failure to do so may adversely affect performance and the lifetime of this unit. • Clean the interior surface with lukewarm water using a soft cloth.
The unit should always be plugged into its own individual electrical outlet which has a voltage rating that matches the rating label on the unit. This provides the best performance and also prevents overloading house wiring circuits that could cause a fire hazard from overheating. Never unplug the unit by pulling on the power cord. Always grip the plug firmly and pull straight out from the receptacle. Repair or replace immediately all power cords that have become frayed or otherwise damaged.

OPERATION- QUICK SETUP GUIDE This section explains how to operate your unit. For more detailed instructions on changing the parameters of the control panel, see page 9. Once plugged in, the display will show the product temperature inside the refrigerator and the compressor will start to run (an indicator light on the control panel will turn on at the same time). Note: this product utilizes two sensors: Product Sensor (display sensor) and Air Sensor (control sensor).
Power Failure Alarm After plugging in the equipment, move the “Reset Switch” located at the front of the unit to the down position. When electrical power to the equipment is lost, an alarm will sound, and it will silence when the power is restored. Note the alarm is battery-powered and has a limited time to alarm. Min/Max Temperature Recording Once connected to the power supply, your unit records the maximum high and minimum low temperatures reached inside the cabinet.

DETAILED TEMPERATURE CONTROLLER GUIDE Front Panel Operation 1. Set temperature (compressor’s top temperature) adjustment: Press the SET button, the set temperature is displayed, then press the UP or DOWN arrow to store and memorize. Press the SET button to exit the adjustment status and display the product temperature. If no more buttons are pressed within 6 seconds, the refrigerator prod uct temperature will be displayed. (Set temperature adjustment range: Parameter E1~E2) 2.
B) Change display to “°F” in lieu of “°C” - After entering the password press the set button about 25 times to reach the “CF” display, then press the up or down arrow unit the control displays “°F” then press set. Wait 6 seconds and it will be set and the unit will go back to normal operation. C) High Air Alarm Settings - After entering the password press the set button until you reach the “C1” display, then press the up or down arrow unit the control displays your desired setting then press set.

Function Details Temperature Control: After turning on the unit and reaching the delay time (parameter E40), the compressor starts operating when the cabinet temperature is higher than (set temperature + hysteresis) and will be off when the cabinet temperature is lower than the set point temperature. To protect the compressor, it cannot be re-started unless the time after the compressor stops is longer than the delay time (Parameter E41).
When the electric supply is off, flash and display EEL and alarm. When setting do1 is set at “00”, unit will not alarm when door is open. When setting do1 is set at “0”, once unit reaches the delay time, it wil flash and display dr alarm, press random button to cancel. If setting C7 is set to “0”, then the units relay does not alarm when power is off. If setting C8 is set to “0”, then after alarm is canceled, the alarm relay does not close.
Circuit Diagram When the door is closed, normal close contact When the door is open, contact is disconnected Notes for Installation: 1. Sensor leads must be kept separately from main voltage wires in order to avoid high frequency noise induced. Separate the power supply of the loads from the power supply of the controller. 2. When installing, the sensor must be placed with the head upward and the wire downward 3. The temperature controller must not be installed in an area where water drips.
CLEANING & MAINTENANCE Before cleaning, it is essential that you unplug the refrigerator from the power line and transfer the contents where they can be stored and monitored at the correct temperatures. • Wash the inner compartment with warm water and neutral detergent. DO NOT allow the control panel, cables or plug to get wet. NEVER use corrosive detergents, wire brushes, or abrasive scourers to clean your refrigerator. NEVER use metal or sharp implements to remove debris. • Dry all surfaces thoroughly.
TROUBLESHOOTING You can solve many common problems easily, saving you the cost of a possible service call. Try the suggestions below to see if you can solve the problem before calling the servicer. Problems Possible causes Remedy Unplug the power cord and reconnect the plug to power supply or replace with a new fuse Disconnect the power supply immediately and reconnect with it after normal voltage. It is necessary to have a voltage stabilizer in case of poor power supply.
The display shows “SC” and compressor does not run The temperature sensor is short circuited. Call for service The display shows “HH” and compressor does not run The ambient temperature is above 40°C/104℉ Stop using immediately The display shows “LL” and compressor does not run The ambient temperature is below -40°C/40°F. Stop using immediately If you continue to experience issues, contact Accucold’s technical support department at 718-893-3900.
