Transport and Storage Environmental Conditions (not to exceed 15 days)

Ambient temperature range of -40°F (-40°C) to +158°F (+70°C)
Relative humidity range of 10% to 100%, including condensation
Atmospheric pressure range of 50KPa to 106KPa

The Enthermics Medical Systems Warming
Cabinet has been thoroughly tested,
checked for calibration, and inspected to
insure only the highest quality. When you
receive your unit, check for any possible

shipping damage and report it at once to the delivering carrier.

The cabinet, complete with unattached items and
accessories, may be delivered in one or more packages. Save all
the information and instructions packed inside the cabinet.

Complete and return the warranty card to the factory as
soon as possible to assure prompt service in the event of a
warranty parts and labor claim. All claims for warranty must include

the full model number and serial number of the cabinet.

After unpacking the unit, allow it to remain under stable
atmospheric conditions for several hours before connecting to
the power source. Extreme changes in temperatures and/or
humidity during storage and/or transportation could have
allowed condensation to form in the unit.

NOTE: Pay particular attention throughout this manual to

the warning and caution symbol which
means: Attention, Consult Operation

Manual before proceeding.

ELECTRICAL INFORMATION

The power specifications are located on the unit
identification nameplate. This nameplete is permanently
attached to the unit and must be located to determine and
verify power requirements.

POWER REQUIREMENTS

120 V.A.C. — 60 Hz, 1 ph
1000 Watts, 8.0 Amps

The single compartment warming cabinet is constructed with 22
gauge stainless steel exterior casing and door, with handle and
hinges designed to withstand heavy usage. The cabinet is heated
by the Halo Heat@ system incorporating low watt density cable
mounted around the compartment walls. This system provides
evenly distributed heat without the need of a heat-circulating fan.
The cabinet is controlled by an adjustable, electronic thermostat,
which includes a heat indicator L.E.D., temperature set button,
temperature increase and decrease button, and digital display to
monitor compartment temperature. The thermostat has a
temperature range of 90°F (32°C) minimum to 200°F (93°C)
maximum. The chamber is equipped with one (1) white, epoxy­coated blanket support assembly with shelf, and furnished with
one (1) set of 5" (127mm) heavy-duty casters — two rigid and two
swivel with brake.

PREPARATION

Before operating the cabinet, clean both the interior and exterior
of the unit with a damp cloth and mild soap solution. Wipe with
an appropriate disinfectant. Clean and install the cabinet shelf
assembly. Do not install or operate the blanket warmer in close
proximity of flammable anesthetics.

OPERATIONAL PROCEDURES

• L.E.D., Light Emitting Diode, referred to is an

electronic device providing illumination.

1. TURN POWER SWITCH ON.

The heat indicator L.E.D. will illuminate and remain

lit while the unit is calling for heat. The digital
display will indicate air temperature of the heated
compartment. The heat indicator L.E.D. will go out
when the air temperature inside the unit reaches the
temperature set-point on the electronic thermostat.

2. VIEW OR CHANGE SET-POINT.

A. Push the SET button once. The set-point value

(current set-point holding temperature) will be
displayed for 5 seconds.

NOTE: Factory default

is 90°F (32°C).

B. The set-point value can be changed by pressing

and holding the SET button for at least 4
seconds. The programming mode becomes
active and the LED1 indicator will blink.

Press

and hold

the UP or DOWN arrow button to
change the value shown in the display. The value
can be stored either by pressing the SET button
or by waiting the exit time-out to expire
(approximately 15 seconds). The new set-point
value will flash three times to confirm. This value
will be retained until it is changed again. The
minimum set-point temperature is 90°F (32°C)
while the maximum set-point temperature is
200°F (93°C). Typical temperature settings are
around 160°F (71°C).

3. LOAD THE CABINET WITH BLANKETS.

Check that the epoxy-coated blanket support

assembly and shelf are in place. The warming
cabinet is designed to elevate blanket temperatures
to a level which will increase patient comfort.
Do not fill cabinet any closer than 2" from ceiling of
warming chamber (If sensor becomes blocked,
overheating could result.) A full load of blankets
will take several hours to reach optimum
temperature. Make certain the cabinet door is
securely closed after initial loading and following
each blanket removal.

DO NOT BLOCK SENSOR BY

OVERLOADING CABINET WITH

BLANKETS. OVERHEATING

COULD OCCUR.

THERMOSTAT

and INDICATOR LIGHT SEQUENCE

Whenever the thermostat is turned “ON,” the heat
indicator L.E.D. will indicate the power “ON/OFF”
condition of the heating cable, and consequently, the
cycling of the cabinet as it maintains the set-point
cavity temperature. If the L.E.D. does not illuminate
after normal start-up, the main power source and
thermostat must be checked. If the warming cabinet
does not hold the temperature as set, the calibration of
the thermostat must be checked. If the warming
cabinet fails to heat with the L.E.D. illuminated, or
heats continuously with the L.E.D. of thermostat “OFF,”
unplug and call for service.

THERMOSTAT ACCURACY

The electronic thermostat is a precise instrument and
is designed to offer trouble-free service. If you suspect
the temperature inside the warming cabinet does not
match the temperature indicated on the digital display,
after stabilizing, follow the instructions listed below.

1. Check to make certain the power meets the
requirements of the appliance, voltage and current
rating as indicated on identification tag.

2. Verify the temperature inside the warming cabinet
with a quality thermal indicator.

A. With the exception of the metal shelves,

completely empty the warming cabinet.

B. Make certain the sensor, located inside the

warming cabinet at the left side of the ceiling,
is completely clean.

C. Suspend the thermal indicator in the center of

the warming cabinet.

D. Allow the temperature, set on the electronic

thermostat, to stabilize for a minimum of one
hour before comparing the digital display with
the reading on the thermal indicator.

DO NOT OPEN THE CABINET DOOR(S) DURING THE

TEMPERATURE STABILIZATION PERIOD

.

If the reading on the thermal indicator does not match
the digital display within 10°F (6°C), contact
Enthermics Medical Systems for appropriate action.

CARE and CLEANING

The cleanliness and appearance of this equipment will
contribute considerably to its operating
efficiency. Make certain the cabinet and
door gaskets 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 shelves
and side guards. Clean these
items separately.

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.

4. Clean the exterior of the cabinet
with a cleaner recommended for
stainless steel. Spray the
cleaner on a clean cloth and
wipe with the grain.

5. If equipped with window doors, clean the glass
with a standard commercial glass cleaner.

NOTE: Do not use abrasive cleansers on the exterior

of the cabinet. Use a non-abrasive cleaner or
distilled white vinegar to remove water spots
or other stains.

DISCONNECT POWER BEFORE CLEANING.
