Owner’s Manual - Regal Intensive Care Unit

Alarm keeps going off.

Remedial Action

First: Make sure that all four panel access knobs on the filter/fans compartment are firmly locked. Failure to lock all four of these knobs will result in oxygen leakage through the air grills between the animal and filter/fans compartments, and consequent loss of oxygen past the loose panel. The alarm system may be triggered by the system’s inability to maintain the requested oxygen concentration due to the leakage.

Second: Your system may be alerting to minor, transient faults. Refer to Setting the Alarm Time Delay Relay on Page 59, and set the delay to a longer period.

Third: Check the set-point setting on the oxygen concentration meter and the flow rate setting on the oxygen flow meter. If these are incorrectly set, the ICU may be having difficulty supplying oxygen fast enough. Refer to Using Oxygen on Page 51 and Controlling the Oxygen Flow Rate on Page 56.

Fourth: You may be leaking oxygen through the animal compartment doors or the filter/fans compartment. Make sure the doors and the panel are securely closed. Refer to Opening and Closing the Doors on Page 48 and Accessing the Filter/Fans Compartment on Page 58.

Fifth: You may be leaking oxygen around the animal compartment doors or the filter/fans compartment. Inspect the gaskets on these items and replace if worn or broken. Refer to Door Gasket on Page 76 or Gasket, Filter/Fans Compartment on Page 129 for part numbers and replacement instructions.
