1.7 Packing
1.7.1 The PGS-2 leak testing device, spare parts kit and maintenance documentation are packed
in polyethylene bags. Accessories kit is wrapped in paper and placed inside the test chamber of
PGS-2.
1.7.2 The PGS-2 leak testing device, together with spare parts kit and maintenance
documentation, is then placed into transportation packing.
2 PROPER USE
2.1 Preparation for use
The device is prepared for use as follows:
2.1.1 Observe safety rules when preparing the PGS-2 leak testing device for use. When closing
the lid, smoothly lower the handle against the stop. When handle is in an intermediate position,
reaction forces of the compressed rubber sealing ring can force fast opening of the lid and injure
the user.
2.1.2 The PGS-2 leak testing device is delivered with disassembled handle, so the screw
handle 13 into the cam 12 before using the device.
2.1.3 Adjust the pressure in the test chamber of PGS-2 and check it for leaktight. To do this,
place the insert 19 (Figure 1) into the test chamber, close the chamber using the locking device.
Readings of the pressure gauge should be within the range of (50 ± 2) mbar. If the pressure is
outside of the range, adjust pressure by using the screw 8. To do this, loosen lock crew 15 and
tighten the screw 8 if you need to increase the pressure in the test chamber, or loosen it if the
pressure needs to be reduced. Then secure the screw 8 with the lock screw 15.
The PGS-2 leak testing device is considered to be properly sealed if after delay time of 5-10 s the
pressure gauge readings remain constant for 2 minutes.
CAUTION!
Make sure the lid is open before adjustment. Otherwise, damage to the lid and seal may occur.
NOTE!
Check the PGS-2 of the leaktight of the device before each time use.
2.2 Using PGS-2
2.2.1 Self-contained self-rescuers shall be tested for leaktight after the temperature maintained
in a room with the PGS-2 device is reached (keep self-contained self-rescuers in this room for at
least 2 hours).
2.2.2 Test self-contained self-rescuers for leaktight following the procedure below:
• place a self-contained self-rescuers into the test chamber and gradually close the
lid using the cam lock device. Readings of the pressure gauge should be within
the range of (50 ± 2) mbar;
• if the pressure is outside of the above range, readjust the pressure as described in 2.1.3;
• wait for 5-10 s (this delay time is needed for stabilization of pressure inside the test chamber)
and record readings of the pressure gauge;
• Observe readings of the pressure gauge to note any pressure changes. The pressure drop
shall not exceed the leaktight value specified in the User’s Manual for the self-contained
self-rescuer being tested.
