Method of use
Prior to performing the internal pressure test, lay out the
gas-tight suit including gloves and boots and full face mask
if appropriate, on a suitable at and clean surface away
from any sources of heat and/or currents of air. Remove any
creases and folds from the suit as far as practicable. Leave the
suit for a minimum of 1 hour at ambient temperature (20 ±
5)°C.
1. Insert the mains lead into the 12v power supply and
plug into an appropriate AC mains electricity supply.
2. Plug the right-angled connector from the 12v power
supply into the socket marked ‘12v DC’ on the control
panel.
3. Connect a clean compressed air source set between 1 -
3.5 Bar (100-350 kPa) max. to the rotating inlet located
at the top left hand corner of the control panel.
4. Using a torque driver with a ‘T8’ Torx bit, loosen and
remove the screw from the centre of one of the suit
exhalation valves, then remove the cap.
5. Carefully slide the diaphragm up the central spigot and
remove from the exhalation valve body.
6. Push the suit adaptor fully into the exhalation valve
body.
7. Seal o any remaining valves on the inside of the suit
using the rubber bungs provided and ensure that the
suit zipper is fully closed.
8. Plug one end of the ination hose into the white
socket on the control panel and the opposite end into
the white socket on the suit adaptor plugged into the
exhalation valve.
9. Turn on the test unit using the green rocker switch
located at the bottom of the control panel (a green light
will illuminate in the switch). The red over-pressure
warning light will illuminate briey and the test unit
computer will boot up into the Respirex testing screen.
10. Press ‘Start’ on the touchscreen computer; the test unit
will commence inating the gas-tight suit, the display
background with turn mauve and ‘INFLATING’ will be
indicated.
11. The test unit will stop ination at the required pressure;
the display background with turn amber, a 10 minute
timer will begin and ‘SETTLING’ will be indicated.
During the 10 minute settling period the test unit may
inject short bursts of air to maintain pressure within the
gas-tight suit.
12. After completion of the settling period the display
background will turn brown and indicate ‘DEFLATING’.
The test unit will allow the gas-tight suit to deate
until the required pressure for the start of the internal
pressure test is reached (1650 Pa).
13. Once the required pressure for the start of the
internal pressure test is reached (1650Pa) the display
background will turn blue; a black trace line will start
to appear from the horizontal line marked 1650Pa on
the display graph and a 6 minute timer will begin. The
black trace line will remain active whilst the test timer
is in operation. Note: Each vertical line on the display
graph indicates 1 minute of elapsed time.
14. After 6 minutes the black trace line will stop and the
nal pressure within the suit will be frozen on the
display. If the pressure reading on the display is above
1350Pa the gas-tight suit has passed the test and the
display background will turn green. If the nal pressure
is below this gure the suit has failed the test and
the display background will turn red. The date and
time, nal pressure in Pascals and result (PASS or FAIL)
are automatically displayed in the relevant elds on
the screen. The user may input information of their
choice into the remaining elds on the screen (Title,
Operator, Location, Suit No. and Notes) using either the
touchscreen keyboard or alternatively a USB keyboard
connected via one of the ports at the lower right hand
corner of the control panel.
15. If required, the nal test may be saved on the computer
by pressing ‘Save’ on the touchscreen, browsing to a
le location of your choice and selecting and suitable
lename. Previous test results can be reloaded to the
display screen by pressing ‘Load’ and browsing to the
relevant le.
16. If a permanent record of the test is required for viewing
or printing on a remote computer an image le can
be saved to a portable USB drive inserted in one of
the ports at the lower right hand corner of the control
panel. Press ‘Save’ on the touchscreen, wait a short
period for the save as box to appear, browse to the
drive letter of the inserted USB drive, choose a lename
and press save. The USB drive can now be removed and
inserted into a remote computer where the image le
can be saved as a backup of the test result, viewed and
printed.
17. After completion of the internal pressure test press
‘Shut Down’ on the touchscreen, allow the computer to
shut down fully then switch o the green illuminated
rocker switch.
