A Word from STERIS Corporation on the Warming of Solutions

Your AMSCO Warming Cabinet is capable of warming fluids, however the user should ALWAYS follow the

specific instructions of the manufacturer of the solution prior to warming any fluid.

In accordance with your facility protocol and recommended practices, in order to reduce possible patient injury,

always verify the temperature of any heated fluid prior to its use or administration.

STERIS offers the following guidelines for warming irrigation and IV fluids in a warming cabinet:

• Before warming irrigation and IV fluids in the warming cabinet, check with the manufacturer of the solution

or fluid for their specific recommendation. The manufacturer’s directions will vary, depending on the

composition of the bottle material, the solution and the manufacturing process.

• Irrigation/IV solutions must be warmed or cooled to the temperature appropriate for the surgical need.

• Infused fluids must be heated or cooled in devices intended for that purpose.

• Manufacturer’s written recommendations for storage, heating and proper use of all skin prep solutions

products must be followed. If the manufacturer has not provided specific instructions on heating, the

manufacturer of the solution must be contacted for clarification before any prepping solution is warmed.

3.1 User Interface

Overview

• Main Power ON/OFF switch.

• ON/Standby button for each compartment (indicator for ON).

ON/Standby button has a built-in delay when turning off to

prevent inadvertently turning the unit off. In standby mode the

heater is turned off, power indicator flashes, LED display

continues to show actual compartment temperature and all other

discrete LEDs are turned off.

• 4-digit red LED display that displays both setpoint and actual

compartment temperatures in °F or °C.

•Up arrow/down arrow buttons to adjust setpoint from 90°F (32°C)

to 160°F (71°C).

•Pre-Set temperature limit for IV Fluids 90°F (32°C) to 110°F

(43°C). Mode key for IV fluids warming section.

• Pre-Set temperature limit for Irrigation/Blankets 90°F (32°C)

to 160°F (71°C). Mode button for this selection.

• Fahrenheit or Celsius selection.

•Key sequence temperature lockout function to prevent

unauthorized temperature changes.

• Visual indicator to show door ajar warning.

• Audible and visual overtemperature alarms to indicate when

actual temperature exceeds 10°F (6°C) above the setpoint.

• USB peripheral connection that allows the end user to plug a

Personal Computer (PC) or laptop computer into the warming

cabinet to retrieve the stored temperature data from controls

memory. The data may be stored or printed from the computer.

This requires a special program that is provided with each

warming cabinet for the end user to install on his/her computer.

• Controls have capability for user prompts and service functions

(display defined error codes).

• Temperature setpoint values and programming are retained in

memory in the event of a power loss. In the event of power loss,

the control resumes the function it was in before the power loss

(the mode [Irrigation/Blankets and °F or °C] and setpoint

temperatures).

3.2 Heating Operation

Overview

• Control automatically operates warming cabinet heating system.

Each compartment has electric heating element(s) and

blower/fan(s) to circulate warm air throughout the compartments.

One control per chamber. The cabinet’s door ajar wiring

removes power to the heater element whenever the door is ajar.

The same switch detects the door status.

• A Resistance Temperature Detector (RTD) air probe is located at

the top of each compartment to monitor internal compartment

temperature and to ensure the compartment reaches and

maintains the correct setpoint temperature. For countertop

OPERATING INSTRUCTIONS 3

P413726-671 Operator Instructions Operating Instructions

model and upper compartment of dual compartment warming

cabinets, the controls ensure accurate compartment

temperature within ±3°F (±1.7°C) of the setpoint for temperature

settings between 90-160°F (32-71°C). The lower compartment of

dual compartment models has an accuracy within ±5°F (±2.8°C)

of setpoint for temperature settings between 90-160°F (32-71°C).

For mid-size model, the controls ensure accurate compartment

temperature within ±3°F (±1.7°C) of the setpoint for temperature

settings between 90-110°F (32-43°C) and accuracy within ±5°F

(±2.8°C) for temperature settings between 110-160°F (43-71°C).

Note that the IV solution warming mode only operates in the 90-

110°F (32-43°C) range for all units.

• The overtemperature alarm activates if the actual temperature

exceeds the setpoint by more than 10°F (6°C). While this

overtemperature output is active, the displayed temperature

flashes alternately with Hi as a visual indicator. The control

resumes normal operation (after an overtemperature condition)

when the measured temperature goes below the setpoint plus

10°F (6°C), but display continues flashing alternately between

compartment temperature and Hi as a visual indicator. The error

message can only be cleared by entering and exiting Standby

mode or turning OFF and back ON main power switch.

• If failure occurs that does not allow the alarm and visual display

to activate when there is an overtemperature situation, the heater

turns off. As a secondary safety feature, if the upper temperature

limit feature fails, the warming cabinet’s thermal fuse limits the

temperature range to 230°F (110°C).

• For a dual compartment warming cabinet, the lower

compartment is always in the Irrigation/Blankets mode.

• IV solutions can only be processed in a countertop model, mid-

size model or the upper compartment of dual compartment

warming cabinet.

3.3 Temperature

Display

• Temperature display is a 3-digit (4th digit for °F/°C indication),

red LED, 0.56” high display that displays setpoints or the actual

compartment (sensor) temperature. The normal function

indicates the actual compartment (sensor) temperature.

• To display the setpoint temperature – push the Up or Down

button for a second and release the button. The setpoint

temperature displays for three to five seconds then reverts back

to display the actual (sensor) temperature. Many residential

digital thermostats operate in the same way.

WARNING – BURN HAZARD:

Before warming IV and

irrigation solutions in the

warming cabinet, check with

the manufacturer of the

solution or fluid for the

specific recommendations.
