    SE400 user instructions — 600006 N CAUTIONS AND LIMITATIONS When using this respirator, observe the following cautions and limitations. Oxygen levels  Not for use in atmospheres containing less than 19.5% oxygen.  This respirator delivers purified ambient air. It does not generate oxygen.

  • Page 7: Unpacking

    Note: NIOSH has classified the foam inserts as a required component. However, foam inserts shall only be used in cases where a satisfactory facepiece fit cannot be achieved without them. UNPACKING The following parts are included with the SE400:  Fan unit ...

  • Page 8: Facepiece Fitting

    FACEPIECE FITTING Note: This section applies to full facepiece respirators only. The SE400 is designed to maintain positive pressure inside the facepiece even under conditions of high workload and stress. However, a quality face seal is essential for optimum protection. This is particularly important in the event that the blower unit stops operating and the SE400 must function as a negative pressure respirator.
  • Page 9 3. Check that the facepiece, demand valve and FTA-400 are complete and correctly assembled 4. Don the respirator in accordance with section Donning the SE400 step 2, steps 4 through 8 and step 12 To prepare for a QNFT using a test facepiece: 1.

  • Page 10: Preparation For Use

    Note: Users who have been approved to use the SE400 only with Full Face Mask Insert (SEA- FI) should check that the insert is correctly fitted and is in good condition prior to donning.
  • Page 11 SE400 user instructions — 600006 N For full facepiece only: 6. Holding the facepiece in one hand and the head harness in the other, place your chin in the cup of the facepiece 7. Pull the head harness over and down the back of your head and stroke it down.
  • Page 12 14. Perform a User Seal Check * by pressing and holding the SE-Talk button for more than three seconds, causing the SE400 to run at full fan speed (“Demist mode”). You should not feel any air leakage around the face seal. After 20 seconds the SE400 automatically returns to normal operating mode.
  • Page 13 SE400 user instructions — 600006 N 17. Check the warning light in front of the mask. It should not be lit. The audible alarm should be silent. If not, investigate. Do not enter a contaminated area until it is resolved 18.

  • Page 14: Working In A Contaminated Area

    Be aware of the SE400 warnings (facepiece warning light, audible alarm)  In the event of a malfunction of the SE400, do not panic. Leave the contaminated area quickly but safely. Do not remove the facepiece from your face until you have reached clean air and have been decontaminated.

    SE-shield breathing hose The SE-shield breathing hose is used in place of the standard breathing hose when the SE400 is used with SE-shield protective suits. The SE-shield breathing hose directs a small amount of filtered air from the SE400 into the suit, maintaining positive pressure inside the suit.

  • Page 17: Filtration Media

    See section Facepiece Fitting. Half facepiece The SE400 half facepiece is intended for use in general industrial environments. It consists of a one-piece silicone facepiece attached to the demand valve. The half facepiece is available in three sizes: Small (RH1-S), Medium/Large (RH1-M/L) and Large (RH1-L).
  • Page 18 Incorrect fitment of filtration media may result in lost or reduced protection of the SE400  The SE400 should be fitted only with matching filtration media – each filter should have the same part number and age. To fit threaded filtration media: Note: Method for SE400AT-2 is shown.

    In these situations the user can expect a shorter available working time in a contaminated area. NIOSH has certified the operating time of the SE400 at 4 hours minimum, in both single and dual battery configurations, under standard test conditions (38 litres per minute) when tested on a breathing machine (USA).
  • Page 20 Low battery warning The SE400 gives a series of audible and visible warnings as the end of operating time approaches. The first low-battery warning occurs approximately 5 minutes before the SE400 shuts down. The warning time is independent of the operating conditions.
  • Page 21 SE400 user instructions — 600006 N To attach the battery to the fan unit: 1. Check that the contacts on the battery and the fan unit are clean and intact 2. Withdraw the locking slide on the fan unit 3. Press the locking tongue 4.

  • Page 22: Battery Charger (Bc3)

    Battery charger (BC1) The SE400 can also be used with the Battery Charger BC1. The BC1 is similar to the BC3 except that it continues to “post trickle charge” indefinitely after initial charging. For this reason, a battery may be left charging overnight to reach full charge, but should not be left on for longer periods as damage to the battery may result.

  • Page 23: Dual Battery Adapter (Db1)

    It connects directly to the fan unit. The SE-Talk is normally mounted on a shoulder strap of the back pack. When the SE400 is used without a back pack, the SE-Talk may be attached to a shirt pocket, or mounted on the SE400 waist belt using the SE-Talk belt attachment (HSE).

  • Page 24: Back Pack

    EX is available for larger waist sizes. Waist belt The waist belt WB1 can be used for wearing the SE400 fan unit on the waist. The fan unit may be positioned on either side of the waist. A waist belt extender WB-EX is available for larger waist sizes.

  • Page 25: Se-Shield Protective Ensembles

    Each SE-Shield ensemble consists of a pressurised protective suit integrated with the SE400. By directing a small amount of filtered air from the SE400 into the suit via SE-Shield breathing hose, positive pressure is maintained inside the suit. This provides added body protection and perceived cooling without reducing the SE400’s high level of...

    Warnings label on fan unit The SE400 fan unit is fitted with a label which summarises the warning conditions likely to be encountered during operation. Models with advanced functionality have an expanded warnings label – refer to supplementary user manual SE400 Advanced Functions for more information.

  • Page 28: Warnings During Start-Up

    Put on the respirator (see section Donning) and breathe normally. After a few breaths it will respond to your breathing. If you wait longer than one minute before putting on the SE400, it will shut down automatically. If the SE400 is not running normally, one of the following warnings will be indicated:...

  • Page 29: Warnings During Operation

    Stand-by mode If the facepiece is removed from the face, an alarm will sound and the SE400 will enter stand- by mode for one minute. If the facepiece is refitted within one minute the SE400 will resume normal operation.

  • Page 30: Demist Mode

    Self-Test The Self-Test is a simple, automated test that the user can perform periodically to check the function and calibration of the SE400. It is a test only. No recalibrations or adjustments are performed. A “Self-Test” should be performed before first use of the respirator and after any maintenance work has been done.
  • Page 31 The lights stay on for one minute, or until the ON/OFF button is pressed. Note: If the battery is in poor condition the Self-Test may abort and shut the SE400 down. In such cases the battery should be checked. Consult section Batteries.
