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.

Quick Troubleshooting Guide
Check these items before calling for service
PROBLEM:
POSSIBLE CAUSE / SOULTIONS:
Unit does not run
• Electrical circuit is not 110-120V 60Hz.
• The power cord is not plugged in.
• No power at electrical outlet. Check to make
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 against rear
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 or side
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 for service.
• 3
rd
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.
P a g e | 10
Appliance runs too
long
• Prolong door openings.
• Control set too cold.
• Room temperature is high which will make the
unit work harder to keep cool.
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
• 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.
Moisture collects
on outside surface
• Hot, humid weather increases condensation.
• As humidity decreases, moisture will
disappear.
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
P a g e | 11
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 the end.
This will “trap” a small amount of water in the loop and prevent air from entering
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.
