Caution – Electromagnetic Interference:
This equipment may cause electromagnetic or other
interference between other devices. If this occurs, move
the equipment away from the affected devices.
Warning – Burn Hazard:
DO NOT exceed 150°F for non-vented closures; (screw
caps, crimp seals, plastic pouches, etc.) Do not exceed
pre-sterile
solution
manufacturer’s
temperature
requirements.
DO NOT raise set temperature to increase rate of
heating. Allow approximately 4-6 hours for solutions to
reach desired temperatures.
DO NOT use liquids on - or inject in – living tissue…
unless actual liquid temperature has been measured
and is acceptable. Temperature of warming cabinet
contents may be hotter than the displayed air
temperature. For patient safety, in accordance with good
medical practice, always check liquid temperature prior
to using.
Caution – Possible Equipment Damage:
Some items are not acceptable in these warming cabinets.
If in doubt as to whether an item can be safely processed,
have facility supervisor contact the manufacturer of the
item.
Process only plastics rated as “thermal” (withstanding

4.2.1 The warming cabinet is equipped with built-in temperature data recorder. The recorder will
record date and time, actual temperature (PV), setpoint temperature (SP), and the status of the upper
and lower chambers at desired intervals (factory set interval = 1 hr) set by the user using “Recorder
Menu” function.
4.2.2 The format of the saved data is as follow:
Format
Date  Month/Day/Year
Time  Hours:Minutes:Seconds
PVUpper  Actual Temperature Upper Chamber (###.#)
SPUpper  SetPoint Temperature Upper Chamber (###)
PVLower  Actual Temperature Upper Chamber (###.#)
SPLower  SetPoint Temperature Upper Chamber (###)
OPUpper  Upper Heater Status, 1 = ON; 2 = OFF
OPLower  Lower Heater Status, 1 = ON; 2 = OFF
4.2.3 Upon inserting a USB stick into the USB port the controller will initialize USB stick, switch the
display to the USB menu. The user will then be able to enter a folder name the logged files will be
saved to on the USB stick.
4.2.4 The recorder log files are stored in .csv format; the first recorder log file written is named
000001-1.csv and placed in the new Recorder sub-folder. Stopping/starting a recording does not
create a new file. If any of these files would exceed the maximum spreadsheet size of 65500 data
lines, a new file is created with the last digit incremented by 1 (e.g. 000001-2.csv then 000001-3.csv).

USER MANUAL
5.0 ROUTINE PREVENTATIVE MAINTENANCE
5.1 Temperature Accuracy
5.1.1 Check display temperature accuracy on a periodic basis with a calibrated thermometer placed
near fan inlet.
5.1.2 Air temperature near fan should be within 2°F / 1. 2°C of display temperature for upper chamber
and counter top models and 3°F / 1.8°C for lower compartment.
5.1.3 If cabinet is not within these guidelines, contact your Blickman sales representative or call
Blickman Customer Service at 1-800-247-5070 with Model and Serial Number (see section 6.5).
5.2 Product Cleaning
5.2.1 Regular cleaning is important to maintain the appearance of stainless steel equipment. Clean
your product with a soft cloth and hot water or commercial stainless steel cleaner according to
the cleaner’s directions.
5.2.2 Shelves, Sloping Top etc. can be cleaned with a solution of liquid dishwashing detergent and
water or a solution of baking soda and water. Rinse and polish dry with a paper towel or soft
cloth. Drying is very important to eliminate any film buildup that may develop from hard water
deposits.
5.2.3 Avoid bleach, acids, strong alkali, and chlorine cleaners. They can cause discoloration, staining
and eventual pitting. If any of these solutions are exposed to the surface, rinse off immediately.
5.2.4 Avoid coarse grit cleaners or steel wool pads. They can contaminate and scratch the surface
leading to staining and rusting.
5.3 Tough Stains and Rust
5.3.1 Most stains are a result of water-borne minerals. Rust stains are a result of iron particles from
an outside source (i.e. water, cookware, etc.) Persistent stains, (including rust) can be removed
with a variety of mild, non-abrasive, stainless steel cleaners. Always rinse thoroughly when
using any cleaner. See the Blickman website for further details at www.blickman.com.
