This warming cabinet is designed to safely warm and store either
irrigation  uids or injection  uids.
The single-chambered warming cabinet is constructed with 20
gauge stainless steel exterior casing and door with handle and
hinges designed to withstand heavy usage. A door with window
allows observation of inventory with the door closed. The cabinet
is warmed using low-heat-density electrothermal cable array. The
electrothermal cable is positioned in the  oor and two sides of the
warming cabinet, providing even heating of the interior chamber.
The interior chamber temperature is regulated by an electronic
control consisting of a 4 digit L.E.D. display, ON/OFF key,
INCREASE and DECREASE keys, integrated LOCK feature and a
series of prompt sequence indicators.
The electronic control can easily be set to operate in Fahrenheit
or Celsius. After a power failure, the cabinet will remember its
programming and begin to operate as before. The ON/OFF
indicator will blink to indicate a failure occurred; pressing the
ON/OFF key once will eliminate this blinking. A thermal shut-
off system, separate from the electronic control, is included as an
additional safety feature.
The control will display temperature in whole degrees.
Fluid warming chamber
The warming cabinet can be programmed to warm either irrigation
 uids (IRR) or injection  uids (INJ), with separate temperature
ranges provided depending on the choice selected.
• IRR temperature range: 37° to 66°C (98° to 150°F),
• INJ temperature range: 37° to 40°C (98° to 104°F).
A fan located inside the chamber mixes the air to prevent
temperature strati cation and to ensure an accurate chamber
temperature for each mode.
• Within +0/-1.67°C (+0/-3ºF) for set points of
43° to 66°C (110° to 150°F)
• Within +0/-1.12°C (+0/-2ºF) for set points of
37° to 43°C (98° to 109°F).
If selected, an alarm will sound if temperatures exceed 6°C (10°F)
over the set-point temperature, and an OVERTEMP indicator will
blink indicating an over-temperature condition.

CLEANING AND PREVENTIVE MAINTENANCE
PROTECTING STAINLESS STEEL, EPOXY COATED AND
PLASTIC SURFACES
It is important to guard against
corrosion in the care of stainless
steel surfaces. Harsh, corrosive,
or inappropriate chemicals can
completely destroy the protective
surface layer of stainless steel, epoxy
or plastic. Abrasive pads, steel wool,
or metal implements will abrade
surfaces causing damage to this protective coating and
will eventually result in areas of corrosion. Even water,
particularly hard water that contains high to moderate
concentrations of chloride, will cause oxidation and pitting
that result in rust and corrosion. In addition, many acidic
spills left to remain on metal surfaces are contributing
factors that will corrode surfaces.
Proper cleaning agents, materials, and methods are vital
to maintaining the appearance and life of this appliance.
Spilled items should be removed and the area wiped as
soon as possible but at the very least, a minimum of once
a day. Always thoroughly rinse surfaces after using a
cleaning agent and wipe standing water as quickly as
possible after rinsing.
CLEANING AGENTS
Use non-abrasive cleaning products designed for use on
stainless steel surfaces. Cleaning agents must be chloride-
free compounds and must not contain quaternary salts.
Never use hydrochloric acid (muriatic acid) on stainless
steel surfaces. Always use the proper cleaning agent at the
manufacturer’s recommended strength. Contact your local
cleaning supplier for product recommendations.
CLEANING MATERIALS
The cleaning function can
usually be accomplished
with the proper cleaning
agent and a soft, clean
cloth. When more aggressive
methods must be employed,
use a non-abrasive scouring
pad on difficult areas and
make certain to scrub with
the visible grain of surface
metal to avoid surface
scratches. Never use wire
brushes, metal scouring pads,
or scrapers to remove residue.
ANNUAL PREVENTATIVE MAINTENANCE
1. Ensure that the correct Operation and Care Manual is
available to all users.
2. Ensure that all users have been properly trained in
unit’s operation.
3. Do not exceed the unit’s capacity.
4. Inspect condition of plug and cord. Replace if damaged.
5. Clean dust from outer vents surrounding the unit and
around top of bonnet (if applicable).
6. Check door gasket integrity. Are there any tears? Is the
gasket worn or loose? Make sure seal is tight to unit
body. Replace gasket if integrity is compromised.
7. Check air temperature sensor mount on the interior of
chamber. Is the guard in place? Are the wires in
good condition?
8. Check insert assembly (depends on unit):
• Blanket Warmer: Check the blanket support
assembly and shelf. Is the assembly in place?
Are any pieces missing?
• Fluid Warmer: Check basket and side rail condition.
Do baskets move smoothly and freely?
9. Check condition of casters or feet condition. Ensure
components are secure and tightly threaded.
10. Check control panel overlay condition. Are there any tears
or excessive wear on the graphic? Does the control work
properly when buttons are pushed?
11. Check that all control and interior LEDs light up.
12. Is the set temperature comparable to the actual
temperature displayed?
Contact service for immediate repair
if any of the above problems exist.
CAUTION

The cleanliness and appearance of this equipment will contribute considerably to its operating
efficiency. Make certain the cabinet and door gasket are kept free of any debris that may accumulate.
Good equipment that is kept clean works better and lasts longer.
CLEAN THE UNIT REGULARLY:
1. Disconnect the cabinet from the power source.
2. Remove all detachable items such as metal basket and basket rail supports. Clean
these items separately.
NOTE: Avoid the use of abrasive cleaning compounds, chloride based cleaners, or cleaners
containing quaternary salts. Never use hydrochloric acid (muriatic acid) on stainless steel.
3. Clean the interior metal surfaces of the cabinet with a damp cloth and any mild
commercial detergent. Avoid the use of abrasive cleaning compounds. Rinse surfaces
by wiping with sponge & clean warm water. Remove excess water with sponge and
wipe dry with a clean cloth or air dry. Leave doors open until interior is completely dry.
4. Interior can be wiped with a sanitizing solution after cleaning and rinsing. This solution must be approved for use
on stainless steel surfaces. Replace support assembly.
5. Clean the exterior of the cabinet with a cleaner recommended for stainless steel surfaces. Spray the cleaner on a clean
cloth and wipe with the grain of the stainless steel.
6. Clean the window glass with a standard commercial glass cleaner.
7. Wipe control panel, door vents, door handles, and door gaskets thoroughly since these areas can harbor debris.
8. Wipe door gaskets and control panel dry with a clean, soft cloth.
9. To help maintain the protective film coating on polished stainless steel, clean the exterior of the cabinet with a
cleaner recommended for stainless steel surfaces. Spray the cleaning agent on a clean cloth and wipe with the grain
of the stainless steel.
Always follow appropriate state or local health (hygiene) regulations regarding all applicable cleaning and sanitation requirements.
