Attach The Facepiece; Attach The High Pressure Manifold - Honeywell TESTAIR 4 Guide D'installation

High pressure manifold
The high pressure manifold can be recognized by its
stainless steel T-fitting and handwheel.
Support to test F1 facepiece with helmet
The support is to placed between base box and head
and fixed by the screws of the head.
Adaptor for facepiece with "Air-Klick" system
The adaptor is used to test the tightness of the
facepieces with "Air-Klick" system. The adaptor is to be
plugged on facepieces and RD40 screw blank can be
installed for tightness test
RD40 screw blank
The RD40 screw blank is used with "Air-Klick" adaptor
for facepiece tightness test

7.2 Attach the Facepiece

Position the facepiece squarely on the test head, and
tighten the straps evenly. Make sure the face piece's
inner sealing surface is flat, sealed to the test head,
and that nothing compromises the integrity of the seal.
Make sure the nose cup is positioned over and across
the test head nose.
Do not connect the second stage regulator to the
facepiece until the software instructs you to do so. The
facepiece must be vented and open to ambient air
pressure when the facepiece leak test is started.
For F1 attachment system use the support described
earlier.

7.3 Attach the high pressure manifold

1. Turn off the cylinder valve on the SCBA to be
tested and depressurize it by using the bypass.
2. Disconnect the SCBA from the cylinder. If the
cylinder will not be used as the pressure source for
testing, it can be removed during testing.
3. Select the manifold that matches the supply
pressure of the SCBA and connect the handwheel
on the single end of the pressure-reducing
manifold to the TestAir 4 through the high pressure
inlet fitting located on the lower right front panel of
the TestAir 4. Make sure the handwheel is tight.
The correct manifold must be used to ensure
the correct results during the bypass flow test.
Use of the incorrect manifold can lead to
incorrect bypass flow test results, serious
injury, or death.
If a pressure supply other than a cylinder is
used, make sure the supply regulator is set to
the appropriate pressure.
Do not attempt to service SCBA without the
proper training from the SCBA's manufacturer.
