What does TEMP.DIFF. >1°C mean on Maquet Heater?
If the Maquet Heater displays the message “TEMP.DIFF. >1°C” once, it is likely due to the coupling or decoupling of the oxygenator during operation. Acknowledge the alarm with the “Alarm Off” key during operation.
How to fix stiff couplings on Maquet HU 35?
If the couplings on your Maquet Heater are stiff, it is likely that the sealing ring is dry and brittle. Apply Vaseline, silicone grease, or a similar product to the sealing ring.
Why does Maquet HU 35 Heater show “TEMP.DIFF. >1°C” every 10 minutes?
If the Maquet Heater displays the message “TEMP.DIFF. >1°C” every 10 minutes, it could be due to a defective heating cartridge or pump, an interrupted bypass, or insufficient heat dissipation. Do not operate the unit continuously (>1h) without the tubes and oxygenator.
