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 to
take many pictures to demonstrate and document the damaged area(s). This has to
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
1. SUITABLE LOCATION
Ambient Temperature –Unlike a household refrigerator, this equipment is designed
for scientific / medical application. Many components are heavy duty and extra
sized, in order 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,
in order 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.

P a g e | 6
2. 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 as fan 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.
3. (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.
4. 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.

4-20mA REMOTE MONITOR
The Touch Screen Display, provides
a 4-20 ma current sink on pins 1
(Input) and 2 (Output). The
indicating element(s) may be loop-
powered as well, as long as the net
voltage across the output exceeds
3V d.c. but is less than 90V d.c.
The transmitter may be connected
anywhere in the loop. A typical
installation would be a 15V supply
driving one indicator and the Touch
Screen Display. The AP may be
connected before or after the
indicator in circuit so you can use
indicators, whose negative loop
connection (loop return) can be at
the same potential as their power
supply ground if they are not loop-
powered.
Circuit recommendations.
Resolution:- 0.06mA
Accuracy:- +/- 2%
Minimum supply voltage 3V + Indicator compliance (VI)*
Maximum supply voltage 90V
*The AP board needs a minimum of 3V to operate and this plus the maximum
operating voltage (compliance) of the indicator will determine the minimum power
supply voltage. For example, if the indicator can take up to 6V, then the minimum
power supply voltage will be 3+6 = 9V.

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 [phone] Option 4

P a g e | 17
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, in order 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 and
7°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.

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 in order to provide users the content temperature. For the actual
operation, the air 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 to 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. [phone] Option 4
