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.

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 unit. This
makes it easier to maneuver it for annual maintenance or service.
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 that the refrigerator (or freezer) is slightly tilted backward (5°.)
This allows the non-self-closing door to shut properly and condensate water flow
out more easily.
INSTALLATION

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.

Quick Troubleshooting Guide
P a g e | 9
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 | 10
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 (SeeQuick
Troubleshooting Guide above)
3.
Make sure there is a water trap (U-shaped loop) in the drain tube nearthe
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.

Maintenance and Cleaning
P a g e | 12
For Swinging door units, pay attention to the gasket and its seating surfaces.
Any debris buildup on these can cause air leaks into the compartment resulting
in condensation as well as reduced efficiency.
CONDENSER MAINTENANCE
Air is pulled through the condenser continuously during operation. Along with this air
come impurities like dust, lint, grease, etc.
These impurities accumulate in the condenser. Dirty condensers result in inefficient
operation, compressor failure and potential product loss which are not covered by
warranty.
If you keep the condenser clean, you will minimize your service expense and lower
your electrical costs. The condenser requires scheduled cleaning every 30 day (or
more frequently in dirty environments).
Proper cleaning involves removing dust from the condenser. This can be
accomplished using a soft brush, by vacuuming, and by blowing through the
condenser coils with pressurized air, CO2, or nitrogen.
• REMEMBER, THE CLEANING OF THE CONDENSER IS NOT COVERED BY THE
WARRANTY AND IS YOUR RESPONSIBILITY. ANY DAMAGE CAUSED BY FAILURE
TO KEEP THE CONDENSER CLEAN IS ALSO NOT COVERED BY THE WARRANTY.
CLEANING THE CONDENSER
1.
Disconnect the electrical power to the unit
2.
Removed the louvered grill at the base of the unit. Locate the condensing unit.
3.
CAUTION: Use eye protection while performing the steps 4-6 to avoid eye injury.
IMPORTANT WARRANTY INFORMATION
