Alarm keeps going off.
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.
