• Leave the shelves in place so that children may not easily climb inside.

SAVE THESE INSTRUCTIONS

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 the performance and the lifetime of this unit.

• Clean the interior surface with lukewarm water using a soft cloth.
  Installation of your equipment

• Units with “BI” in their model number are designed for recessed installation or freestanding use.
  The rest of the units listed in this manual are designed for freestanding use only. All models are for indoor use only.

• WARNING : Do not store or install the unit outdoors.

• CAUTION: This equipment is designed for the storage of medicine or other medical products. Do not store beverages or perishable food in this unit.

• Place the refrigerator on a floor that is strong enough to support it when it is fully loaded. To level the unit, adjust the front leveling legs.

• For freestanding installation, allow at least 5 inches (127mm) of space between the back, top, and sides of the unit. This allows the proper air circulation to cool the compressor and condenser for energy saving. Even for recessed installation (units with “BI” in the model number), it is recommended to keep ¼” (6.35mm) of space on each side and at the top, and 2” (51mm) at the rear to ensure the best performance. The air vent at the front of the unit must never be covered or blocked in any way.

NOTE: It is recommended that you do not install the unit near an oven, radiator or another heating source. Direct sunlight may affect the acrylic coating and heat sources may increase electrical consumption. Don’t install in a location where the temperature will fall below 60°F (16°C). For best performance, do not install the unit behind a cabinet door or block the base grille.

• Avoid locating the unit in moist areas.
• Plug the unit into an exclusive, properly grounded wall outlet. Do not under any circumstances cut or remove the third (ground) prong from the power cord. Any questions concerning power and/or grounding should be directed toward a certified electrician or an authorized service center.

Electrical connection

WARNING Improper use of the grounded plug can result in the risk of electrical shock. If the power cord is damaged, have it replaced by a qualified electrician or an authorized service center.

This unit should be properly grounded for your safety. The power cord of this unit is equipped with a three-prong plug which mates with standard three-prong wall outlets to minimize the possibility of electrical shock.

Do not under any circumstances cut or remove the third (ground) prong from the power cord supplied. For personal safety, this equipment must be properly grounded.

This unit requires a standard 115/120 Volt AC ~ 60Hz three-prong grounded electrical outlet. Have the wall outlet and circuit checked by a qualified electrician to make sure the outlet is properly grounded? When a standard 2-prong wall outlet is encountered, it is your responsibility and obligation to have it replaced with a properly grounded 3- prong wall outlet.
To prevent accidental injury, the cord should be secured behind the unit and not left exposed or dangling.
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. Do not use a cord that shows cracks or abrasion damage along its length or at either end. When moving the equipment, be careful not to damage the power cord.
Electrical connection
Because of potential safety hazards under certain conditions, it is strongly recommended that you do not use an extension cord with this equipment. However, if you must use an extension cord it is absolutely necessary that it be a UL/CUL-Listed, 3-wire grounding type equipment extension cord having a grounding type plug and outlet and that the electrical rating of the cord be 115 volts and at least 10 amperes.
Reversing the door
Unless ordered with option “LHD,” your unit has shipped with a right-hand self-closing door swing. If you wish to reverse the door to open from the opposite direction, follow the steps listed below.

NOTE: Reversing the door will undo the self-closing function. Doors on units with “DL2B” data logger suffix are not reversible.

1. Carefully lay the unit on its back and remove the two front leveling legs
2. Remove the two hex head screws that connect the door hinges to the body on the bottom of the unit
3. Remove the two flathead screws that connect the hinge assembly to the bottom of the door 4. Remove the white hinge from the square rod
4.  Slide the door towards the bottom until it is free of the top hinge
5. Unscrew the top hinge pin from the unit and reinstall on the left side
6. Flip the door so the handle is now on the right side
7. Push the door onto the top hinge piece.
8. Reinstall the hinge assembly on the left side bottom of the door using the flathead screws
9. Push the white hinge onto the square rod at a position of 9 o’clock
10.  Turn the white hinge clockwise until the holes line up with screws located on the bottom of the unit
11. Replace the hex head screws and front leveling legs

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 10.

Once plugged in, the display will show the product temperature inside the refrigerator and the compressor will start to run (indicator light on the control panel will turn on at the same time).
NOTE: This product utilizes two sensors: A Product Sensor (display sensor) and an Air Sensor (control sensor).

For maximum performance, the refrigerator controls use a separate air sensor. This allows it to rapidly respond to product loading and door openings. You may need to adjust the controller lower than the desired product temperature as the air temperature needs to be lower to pull the product temperature down.

The temperature displayed is the product temperature recorded by the product sensor in glycol inside a vial located in the refrigerator. As the refrigerator cools to the setpoint, the number on the display will decrease accordingly. The product vial will take longer to cool than the air in the refrigerator.

If power is cut off, wait for at least 5 minutes before plugging the unit in again to avoid damaging the compressor.

Adjusting the Operating Temperature
To change the setpoint, press the SET key and the set-point temperature will be displayed. To change the setpoint, within 10 seconds, press the up or down arrow key until the desired temperature is displayed. The new set point will be memorized when you push the SET key again.
Glassdoor models come preset to 4°C and solid door models are factory set to 5°C. Adjust the temperature up or down to achieve your desired product temperature the displayed temperature.
High/Low-Temperature Alarm
If the temperature in your refrigerator drops below the air low alarm set point, an alarm will sound. The front panel display will flash LO and the current temperature will be  displayed alternately. Also, if the temperature rises above the high air alarm setpoint an alarm will sound.

The front panel display will flash HI and the current temperature will be displayed alternately. if the temperature rises above the high product alarm setpoint an alarm will sound.  The front panel display will flash H2 and the current temperature will be displayed alternately. There could be a number of reasons for this which should be investigated immediately.
The refrigerator should be monitored to check that it is returning to the correct temperature. Set the alarms values to meet your requirements in the parameter set-up and settings.
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. The display will show the last HI and LO temperatures recorded until the refrigerator is reset.
• To display the HI reading, press and release the HI/LO button. To display the LO reading, press and release the HI/LO button again.

  To Reset the Min/Max Temperature Recording
Hold the HI/LO button for 6 seconds. To confirm the operation, the display starts blinking, and the buzzer sounds. After 5 seconds, the normal display will be restored.

Changing the Temperature Display
This unit ships with the temperature being displayed in Celsius. If you prefer the display in Fahrenheit, you will need to enter your password and adjust the parameters. Press and hold the “Set” button until it flashes “Pas,” then enter the password (factory default is “15”) using the up and down arrows. Once you enter the password, press “Set” about 25  times until “CF” displays, then press the down arrow until the control displays “ºF”, then press “Set.” Wait 6 seconds and the setting will be recorded, with your unit resuming normal operation.
Interior Light
Your unit includes an LED light that will automatically illuminate when the door is opened. If you would like to keep the light on when the door is closed, push the switch to the  “on” position.
Door Alarm
If the door of the refrigerator is left open for more than 3 minutes, an audible alarm will sound. The alarm will be turned off automatically when the door is closed.
Remote Alarm
The electronic controller is equipped with dry contacts for alarm forwarding to an external remote alarm system (terminal block on the back of the refrigerator).
NOTE: The remote contacts are normally “closed” and “open” upon alarm. To change the output to normally “open” and “closed” on alarm see item “C12” of the Table of  Parameters and Factory Settings. Change the “C12” setting to “00” in lieu of “01”.

Summary of Alarm Types

Storage of articles

• At maximum loading level, the content should not block the refrigerator’s airflow or be loaded above the load line.
• Leave space around the contents to allow a smooth flow of cold air inside the cabinet. To prevent freezing, be sure the articles do not touch the back of the interior cabinet.
• Store articles away from the inner fan.

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 setpoint 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). Defrost Control: After running for a defrost interval set time (parameter F2), the unit will enter
defrost and the compressor stops. When the defrost duration time (parameter F1) ends, it will exit defrost status. After a defrost period ends, there will be 2 minutes of dripping time before the unit can enter refrigeration status.

• When defrosting interval F2 is set to “00”, the automatic defrost by turning off the compressor will be canceled.
• When setting parameter F4 is set to “0”, the temperature will be displayed normally during defrost.
• When setting parameter F4 is set to “1”, the cabinet temperature is locked during defrosting, and the last value before defrost is displayed. When defrosting ends, the normal display will resume after temperature display 20 minutes delay (or cabinet temperature lower than the set temperature). The defrost LED flashes during the delay.
• When setting parameter F4 is set to “2”, the set temperature will be displayed during defrosting.
• When defrosting ends, the normal display will be resumed after 20 minutes delay (or cabinet temperature lower than the set temperature). The defrost LED flashes during the delay.
• When setting parameter F4 is set to “3”, dEF will be displayed during defrosting. When defrosting ends, the normal display will be resumed after 20 minutes delay display dEF (or cabinet temperature lower than the set temperature). The defrost LED flashes during the delay.

Alarm Control: After turning on for the first time, the unit will need to reach the C5 delay time setting, then the high/low-temperature alarm function can be triggered (C1, C2,  C3). After passing C5 delay, when the cabinet temperature is abnormal (for example higher than the temperature alarm C1 or lower than temperature alarm C2) and duration more than alarm delay time C6, the unit will enter alarm status, alarm start. When the high-temperature alarm alternate displays H1 and cabinet air temperature, the compressor starts to run. When a low-temperature alarm, will alternate display L0 and cabinet temperature, the compressor stops.  When cabinet temperature is higher than the (low-temperature alarm value C2 + alarm hysteresis C4), the low- temperature alarm ends. When cabinet temperature is lower than  (high- temperature alarm value C1 –alarm hysteresis C4), the high-temperature alarm ends.
When the product sensor temperature is greater than ore equal to the product temperature high-temperature alarm value C3 and duration more than alarm delay time C6, unit enters alarm status and starts the alarm, alternate display H2 and cabinet temperature. When the product sensor temperature is less than or equal to the(high-temperature alarm value C3 – alarm hysteresis C4), it will end the high-temperature alarm.
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 will flash and display “dr alarm”, press the random button to cancel.
If setting C7 is set to “0”, then the unit’s relay does not alarm when power is off.

If setting C8 is set to “0”, then after the alarm is canceled, the alarm relay does not close. If C9 is set to “0”, then after the alarm cancel button is pushed, the buzzer does not  restart. If setting other numbers, then after reaching delay time, the buzzer sounds one more time. (Under the condition of alarm not terminating)
Abnormal work mod e: When air sensor is short-circuited or high temperature over limit (＞ 66°C/151°F), “1H” is displayed; when air sensor is open-circuited or low temperature over limit (＜40°C/°F) “1L” is displayed. The compressor will enter the force running mode, according to C10, C11 set parameters running in sequence.
When product sensor is short-circuited, open-circuited or over-limit (＞66°C/151°F), alternate display 2H and air temperature, the product temperature sensor open-circuited  or low temperature over limit (＜-40°C/°F), alternate display 2L and air temperature.

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 AND MAINTENANCE

Before cleaning, it is essential that you unplug the unit 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.
• To ensure trouble-free operation, the condenser should be cleaned every three months where appropriate using a vacuum hose. The condenser is located at the back of the cabinet. In exceptionally dusty locations, the condenser should be cleaned more often.
