WARNING: Improper adjustment of the warming unit's normal
operating temperature could result in patient exposure to
temperatures outside of the indicated range, and may lead to
patient injury.
• Closely follow instructions for temperature adjustment.
• Always use a Model 221 Temperature Test Kit or a Model 22110
Temperature Test Unit to verify output temperatures.
• Always make adjustments relative to the HIGH temperature
setting on the warming unit. When the HIGH setting is accurately
adjusted, the MED and LOW settings should also be within
specified limits. If the HIGH range is properly set, and MED and/
or LOW do not meet specs, call Technical Service.
• Recalibrate the temperature test kit at least once a year. The
Model 22110 Temperature Test Unit does not need to be
calibrated. The meter it is connected to must be calibrated.
Follow the calibration instructions in the meter service manual or
follow standard facility calibration schedules.
• When in doubt, contact Technical Service for assistance in
temperature adjustment.
