What to do if 3M Ranger 247 Medical Equipment warming unit displays low temperature alert?
If the 3M Medical Equipment warming unit's alphanumeric display flashes a temperature of 33°C or below along with the word “LO,” and the alert indicator illuminates with a sound, the alert should stop when the temperature rises above 33°C. This under-temperature condition may be caused by very high flow using very cold fluid, or a defective heater/relay. If the alert continues, turn off the unit, unplug it, and discontinue use.

How to remove cassette from 3M Ranger 247?
To remove the cassette from the 3M Medical Equipment, ensure that: * Fluid is drained from the cassette before sliding it out. * Fluids are no longer infusing. * The clamp is closed proximal to the warming cassette. Also, if the warming unit is below the patient level, raise it above the patient level to avoid excessive back pressure.
What to do if the 3M Ranger 247 warming unit displays a high temperature alert?
If the alert indicator illuminates and you hear alert sounds, and the display flashes a temperature of 48°C or higher along with the word “HI,” it indicates a temporary over-temperature condition. This can happen due to rapid changes in flow rates, starting the unit before inserting the warming cassette, or using fluids pre-warmed above 42°C. To resolve this, increase the flow to lower the temperature. The alerts will stop when the temperature drops below 48°C, and the unit will be ready for use. If this doesn't work, turn off and unplug the unit, stop the fluid infusion, and avoid pre-warming fluids before using the 3M Ranger irrigation fluid warming unit.

Ensure the power cord is plugged into the power entry module of the warming unit. * There may be a unit failure. Check the fuses.
