Scott Self-Contained Breathing Apparatus SKA-PAC PLUS

NOTE: AFTER CLEANING THE REGULATOR, VERIFY THAT ALL MOISTURE HAS BEEN REMOVED FROM THE REGULATOR AS DESCRIBED IN THE REGULATOR CHECK SECTION OF THIS INSTRUCTION.

Remove the breathing regulator from the facepiece by pulling back on the locking clip and rotating the regulator 1/4 turn clockwise.

Remove any obvious dirt from the external surfaces of the regulator using SCOTT recommended sanitizing or disinfecting cleaner with a sponge or soft cloth.

Inspect the inside of the regulator assembly through the regulator opening. If excessive dirt or soil is present, forward regulator assembly to SCOTT trained authorized personnel for thorough cleaning.

Depress the donning/air saver switch, close the purge knob by turning fully clockwise. Use the SCOTT recommended sanitizing or disinfecting cleaner in the regulator opening and the immediate area around the opening. Be sure to cover internal components completely.

Follow the user instructions for the SCOTT recommended cleaner. A specific contact time may be required for sanitizing or disinfecting before rinsing.

Rinse the regulator with drinking water using a spray bottle or gently running tap water.

Shake excess water out of regulator. Completely air dry the regulator before use.

NOTE: TO SPEED DRYING OF THE REGULATOR, GENTLY BLOW DRY WITH CLEAN, DRY BREATHING AIR OF 30 PSIG MAXIMUM. DO NOT USE SHOP AIR OR ANY OTHER AIR CONTAINING LUBRICANTS OR MOISTURE.

Verify that the purge valve is closed. Depress the air-saver/donning switch fully and release.

Don the facepiece or hold the facepiece tightly to the face.

Open the cylinder valve by turning the valve knob counterclockwise fully. No air flow shall be detected at this time. Inhale sharply to start the flow of air, then take one breath and hold. Air shall flow freely into the facepiece during inhalation and stop when inhalation ceases.

Hold breath for 5 to 10 seconds. If airflow continues after inhalation has ceased, recheck the fit of the facepiece. If airflow continues after checking the fit, remove the respirator from service and tag for repair by authorized personnel.

Exhale into the facepiece and take a second breath. Air shall leave the facepiece through the exhalation valve during exhalation and fresh air shall flow into the facepiece on inhalation.

Depress the air saver switch fully and release. Doff the facepiece. No air shall flow from the facepiece.

With the cylinder valve open and the air-saver/donning switch depressed, seal the open end of the fitting on the airline connection hose with your thumb. If an air pressure buildup can be felt with the thumb or if airflow from the airline connection hose can be detected when the thumb is removed from the fitting, DO NOT USE THE Respirator; remove the respirator from service and tag for repair by authorized personnel.

Close the cylinder valve by pushing in on the cylinder valve knob while turning it fully clockwise. Vent any trapped air in the respirator by opening the purge valve momentarily. Close the purge valve when air flow stops. Check the air cylinder gauge to be certain the cylinder still indicates “FULL.”

Connect the respirator to the air supply system using one or more segments of air supply hose. There shall be no air flow from the facepiece. Don the facepiece or place it tightly against the face. Inhale sharply to start the flow of air. Take several breaths. Air shall leave the facepiece through the exhalation valve on exhalation and fresh air shall flow into the facepiece on inhalation.

Warning: Do not attempt to replace components or make adjustments or repairs beyond the scope of this instruction manual without proper training.

Inspect the equipment for worn or aging rubber parts, worn or frayed harness webbing or damaged components.

If the SKA-PAK PLUS respirator is equipped with the full body/fall protection harness, inspect the harness for frayed or damaged webbing or damaged buckles.

If any damage to the harness is found, do not use the full body/fall protection harness. If the full body/fall protection harness has been subjected to fall arrest or impact forces, it must be immediately removed from service and destroyed.

Remove the breathing regulator from the facepiece by pulling back on the regulator retaining latch and rotating the regulator 1/4 turn.

Clean the respirator according to CLEANING THE RESPIRATOR section of this instruction. The unit must be thoroughly dry before storage.

Inspect the gasket on the breathing regulator that seals against the facepiece for rips or damage that may break the seal.

Connect the breathing regulator to the facepiece and rotate until it latches into place. Verify that the latch securely snaps into the notch on the facepiece.

Perform the REGULAR OPERATIONAL INSPECTION described in this instruction manual.

Examine the facepiece assembly for damaged or worn components.

Facepiece complete and in serviceable condition with no worn, loose, or damaged components.

Facepiece seal and other rubber components free from deformation, wear, damage, or cracks.

Lens free from cracks, gouges, scratches, or any condition that could impair the operation of the facepiece or the user’s vision.
