RECEIVING AND SHIPPING DAMAGE HANDLING

Each refrigerator or freezer is carefully inspected to meet our high standard quality assurance policy, before it ships to you. Unfortunately, shipping damage can happen during transportation to you. There are two general types of shipping damage. The first is visible damage. This type of damage includes visible loss, damage, shortage or any external evidence of loss or damage that is visible at time of delivery. This type of damage must be noted in detail on your delivery receipt. Make sure the driver signs and dates the delivery receipt, acknowledging the damages. We also recommend taking many pictures to demonstrate and document the damaged area(s). This must happen at the time of delivery or it won’t happen at all. Keep a copy for your records and send another to the carrier’s damage claims department along with a formal request for an inspection report. Follow up with a phone call. Their contact information can be found on the carrier’s web site.

The second type of shipping damage is concealed damage. This type of damage will probably not be apparent at time of delivery and may not be discovered until unpacking and inspecting the unit. Remember, time is of the essence here. You should unpack and inspect the unit as soon as possible. Each day that passes reduces the likelihood that the carrier will pay the claim. As soon as the concealed damage is discovered, stop unpacking and retain all packing materials. Take many pictures to demonstrate and document the concealed damage area(s). Contact the carrier by phone to report the claim. Note the date and time and person you spoke with.

Get a claim number. Follow up with a written letter referencing the claim number and including a formal request for an inspection. Again, consult the carrier’s website for specific claim instructions and follow them precisely

AS STATED ABOVE, THE CARRIER IS YOUR SOLE SOURCE FOR SATISFACTION OF A DAMAGE CLAIM. UNDER NO CIRCUMSTANCES SHOULD THE MERCHANDISE BE RETURNED TO THE MANUFACTURER. NO RETURNS WILL BE ACCEPTED WITHOUT PRIOR AUTHORIZATION.

INSTALLATION

Please take a moment to follow the steps below, before using this equipment.

1. Find a suitable location to install this refrigerator (or freezer)
2. Level this refrigerator (or freezer)
3. Set up the shelves inside (if applicable)
4. Install the optional monitor probe for field installation
5. Ready to use

SUITABLE LOCATION
Ambient Temperature – Unlike a household refrigerator, this equipment is designed for scientific / medical application. Many components are heavy duty and extra sized, to meet the ultimate temperature performance. Therefore, the sounds generated from its operation may not be accepted by everyone in the room. Please take the operation sound factor into consideration and locate this refrigerator accordingly.

Please ensure the ambient temperature is climate-controlled, between 65°F to 85°F, to achieve the ultimate temperature performance.

Clearance Space – We require 2 to 3 inches of clearance space around the refrigerator. So, it would be easier to remove the refrigerator for annual maintenance, or service.

LEVELING

Once this refrigerator or freezer is at its final location, please level your refrigerator, because it is critical to equipment operation. Here are a few benefits to a good leveled refrigerator (or freezer):

1. Moving mechanical parts,such asfan or compressor, would have less chances to fail, since it is in the designed upright position.
2. Reduce noise.
3. Door(s) would close properly.
4. Condensate water would flow out the refrigerator properly.

To level this equipment, set a leveler in each corner on the top. If the equipment is not level, adjust either the leveling legs or casters.

**** We recommend to slightly tilt the refrigerator (or freezer) toward to the back, about 5 degrees. So, the non-self-closing door can be shut properly, and condensate water would flow out easier.

(OPTIONAL) MONITOR PROBE FOR FIELD INSTALLATION
Each refrigerator or freezer is equipped with a 3/8” probe access port hole for your independent probe installation. The port hole is generally located in the back of your refrigerator (or freezer). Simply remove the white caps, run your probe through, and seal the hole with electrical putty to prevent air from getting into the chamber.

**** DO NOT run your probe through the door gasket, as it may cause serious condensation or a frozen evaporator issue. The port hole is specifically designed to
allow you to install the monitor probe.

READY TO USE
Once you ensure the electrical service is adequate and Steps 1 to 3 are followed, you are ready to use this refrigerator (or freezer). Simply plug in the power cord into the wall outlet.

This refrigerator (or freezer) is factory set to run at its ultimate temperature performance. There should not be a need to adjust the temp settings. If you feel the temp settings must be adjusted, please refer to “TEMPERATURE ADJUSTMENT” section in this manual for more details.

OPERATION

Temperature Controller System

Product Description
The digital microprocessor temperature controller is designed to provide temperature control of refrigerators or freezers. The controller also provides a constant readout of the sample temperature inside of the unit. A touch keypad allows the user to easily select the display units, set point, and differential set point.

**** Please Note: The digital temperature controller has been factory set and tested to allow your unit to operate at its desired temperature cycle.

Adjusting the settings on the controller will alter these factory settings. WE STRONGLY RECOMMEND YOU CONTACT THE MANUFACTURER’S TECHNICAL SUPPORT DEPARTMENT BEFORE MAKING ANY ADJUSTMENTS TO THIS CONTROLLER. TECH SUPPORT PHONE NUMBER IS (800) 648 4041, SELECT THE OPTION FOR TECHNICAL SERVICE.”

CHECK TEMPERATURE HISTORY
Press and release [UP] button. The display will show the maximum temperature ever reached since the last reset. Press and release [DOWN] button. The display will show the minimum temperature ever reached since the last reset. Press and hold [SET] for more than 3 seconds, while the maximum or minimum temp is displayed. (rSt message will be displayed).

CHECK THE SET POINT
Press and release [SET] button. The display will show the current set point value.

Operation

During the normal operation, the refrigerator’s (or freezer’s) compressor would turn on and off, to maintain the cold temperature in the storage chamber.

In this controller, the point where the compressor is cut off is called “SET POINT”.

The point where the compressor is turned on is calculated by adding the value of “SET POINT” and “Hy” (temp differential).

For example, if you wish to maintain the operation temperature between 3°C and7°C, you would set “SET” = 3°C, and “Hy” = 4°C.

“ALU” is the high temp alarm point, and “ALL” is the low temp alarm point. Both alarm settings will alert users when the refrigerator’s (or freezer’s) temp is out of range, via visual & audible alarm, and remote alarm contact.
“US” is the upper setting limit, and “LS” is the lower setting limit. Both limit settings will prevent users accidentally adjust “SET”, “ALU”, or “ALL” outside the range.

-12°F (freezer)
Hy| Temp differential between compressor start and off point| 3°C or 5°F (NOT RECOMMENDED TOCHANGE)
ALL| Low temp alarm point| 1°C or 34°F (refrigerator)-28°C or -18°F (freezer)
ALU| High temp alarm point| 10°C or 50°F (refrigerator)-15°C or 5°F (freezer)
Lod| Screen display choice (air or sample probe)| P3
CF| Celsius & Fahrenheit unit change|
O3| Sample (display) probe calibration / offset| 0
OT| Air (control) probe calibration / offset| 0
US| The maximum limit that SET or ALU couldreach| 10°C or 50°F (refrigerator)-10°C or 14°F (freezer)
LS| The minimum limit that SET or ALL couldreach| 1°C or 34°F (refrigerator)-30°C or -22°F (freezer)

Change the set point (compressor turn-off point)
Press and hold [SET] until °C or °F icon blinking. Press [UP] or [DOWN] to change the setting value. Then, press [SET] once to confirm the new setting.

Change the other settings
Press and hold both [SET] and [DOWN] at the same time until “Hy” appears on the display.

Press [UP] or [DOWN] to scroll different settings. Press [SET] to enter the setting. Press [UP] or [DOWN] to change value. Press [SET] once to confirm the new setting. The display will show the next setting.

At any setting, press and hold both [SET] and [UP] to exit out the setting mode, or simply leave the display alone for 10 seconds.

Change the readout from °C to °F, or °F to °C
Press and hold the [LIGHT] icon button for 5 seconds. The controller will restart and change the display scale from °C to °F, or °F to °C.

Advanced Settings – for service technician only

ATTENTION : This section is for service technicians or experienced users only. Altering the following settings can result in malfunction or inaccurate temperature readout.

Air and Sample Temperature Display
The controller has the capability to display either the air or sample temperature readout. For the normal operation, the sample-simulated temperature (P3) is displayed to provide users the content temperature. For the actual operation,  theair temperature (P1) is used to control the compressor’s cycle.

This is a useful tool for you to make a precise adjustment, or temperature validation process.

“Lod” setting allows you to display either air (P1) or sample (P3). Press and hold both [SET] and [DOWN] at the same time until “Hy” appears on the display.

Press [UP] or [DOWN] until “Lod” shows up. Press [SET] to enter the setting. Press [UP] or [DOWN] to toggle between the air temp “P1”, or the sample temp “P3”. Press [SET] once to confirm the new setting. The display will now show the temp you have selected.

We strongly recommend you change the “Lod” setting back to “P3” before you complete the service. This will allow users to see the sample simulated temperature, and the controller will be able to alert when the sample temp is out of range.

Calibration / offset
“OT” setting allows you to change the air probe’s calibration. “O3” setting allows you to change the sample probe’s calibration.

Please be sure you have a NIST traceable and calibrated thermometer. Place your thermometer’s probe next to our sensor accordingly, air vs. air, or sample vs. sample, before making an adjustment on either “OT” or “O3”.

For more advanced settings, please contact our Technical Service Department for assistance. (800) 648 4041, select the option for Technical Service.

Quick Troubleshooting Guide

Check these items before calling for service

• Electrical circuit is not 110-120V 60Hz
• The power cord is not plugged in.
• No power at electrical outlet. Check tomake sure breaker is not tripped or fuse is not blown. Additionally, make sure unit is not plugged into a Ground Fault Circuit Interrupter (GFCI) type of outlet.

Unit does not maintain at the proper temperature|

• Check the room temperature. We recommend the refrigerator or freezer should be placed in an air-conditioned room between 65°F to 85°F. If the room temp is too warm, the refrigerator or freezer may not be able to maintain the interior temp at proper range.
• Door is not closed properly.
• Amount of stored product is overloaded.
• Product replacements are pushed againstrear wall or interrupted the proper refrigerator air circulation. For the proper air circulation, place the products evenly on each shelf. Do not push against the refrigerator’s rear orside walls.
• Evaporator is blocked by frost or ice. Remove the products, unplug the refrigerator or freezer power, and allow the unit to defrost. If the problem still exists, call forservice.
• 3rd party thermometer is placed incorrectly. For proper temperature monitoring, the thermometer should be place in the middle of refrigerator.

PLEASE NOTE! Prior to shipment, each refrigerator and freezer has been calibrated and tested at proper temperature range

|

• Prolong door openings.
• Control set too cold. Room temperature is high which will make the unit work harder to keep cool

Unit does not maintain at the proper temperature|

• The exterior walls can be as much as 30 degrees warmer than room temperature due to the embedded condenser coils. Thisis normal when the unit is operating.

Appliance runs too long|

• Compressor may be overheated. Please check the room temp and ensure the range is within 65°F to 85°F. If the problem still exists, callfor
• service.

Temperature of external wall surface is warm|

• The exterior walls can be as much as 30 degrees warmer than room temperature due to the embedded condenser coils. This is normal when the unit is operating

Compressor noises|

• Compressor may be overheated. Please check the room temp and ensure the range is within 65°F to 85°F. If the problem still exists, call for service

Moisture collects inside or on outside surface| INSIDE:

• Door gasket is not sealing properly. Check for debris, cracks, and items passing through door at the gasket.
• The refrigerator or freezer is facing a doorway or is underneath of air conditioning vent. Relocate the unit or redirect air vent.
• Too many door openings. Minimize time door is open.
• Hot, humid weather increases condensation.
• Make sure there is a water trap (U-shaped loop) in the drain tube near the compressor. This will “trap” a small amount of water in the loop and prevent air from entering the chamber through the tube. OUTSIDE:
• Hot, humid weather increases condensation.

Odor inside the unit|

• Interior needs to be cleaned. See section on maintenance and cleaning in this manual.
• Make sure product containers are tightly sealed to prevent leakage

Door will not Close|

• The unit is not level. Refer to the Leveling section at the beginning of this manual
• Check for dirt and debris or items passing through the door seal.

MOISTURE DURING THE SUMMER SEASON
The amount of moisture, condensation, or high humidity related issues increase during the summer and, in most cases, will self-resolve when the weather cools down. Please note a refrigeration system will NOT generate moisture or water but simply condenses the moisture that is already in the chamber. Keeping the unit in an air conditioned, low humidity space will resolve many issues. Other things you should check

1. Location of the refrigerator (See Quick Troubleshooting Guide above)
2. Door sealing and frequency of door opening event (See Quick Troubleshooting Guide above)
3. Make sure there is a water trap (U-shaped loop) in the drain tube near theend

This will “trap” a small amount of water in the loop and prevent air from enter
the chamber through the tube.

BEFORE CALLING THE MANUFACTURER’S TECHNICAL SUPPORT DEPARTMENT , please have the unit’s model and serial number ready as well as the problem description. The model and serial number is located on the serial tag which can be found on the interior left upper wall of the unit.
