11. OPERATION

During the test the examined self-contained self-rescuer should have the same temperature as
surrounding air and UPG itself. If the temperature differs, the self-contained self-rescuer should
be stored in the testing room at least for 2 hours before test.
Test the self-rescuers in the following order:
• disconnect the self-contained self-rescuers from the belt (if supplied);
• open the lid of UPG;
• put a self-contained self-rescuer into the chamber and smoothly close the lid with eccentric
lock. The manometer should indicate (5±0,2) kPa ((50±2) mbar);
• wait for 5-10 seconds to let the pressure inside the chamber get stabilized;
• record the manometer indication. Observe the change in the readings of the manometer.
Pressure drop should not exceed the norms, specified in the manual to the tested
self-contained self-rescuer.
Checking the leaktight of the UPG device must be done before testing each batch of
the self-rescuers.
CAUTION!
Test a self-contained self-rescuer with UPG device only if the ambient temperature fluctuation range
is not more than ±2 °C during the test.

12. DAILY MAINTENANCE

Wipe the UPG device chamber with a clean rag and put the inserts into it after use.
In the period between the checks of the self-contained self-rescuer, keep the lid open to avoid
premature failure of the elastic sealing ring.
NOTE!
Avoid direct sunlight on the UPG device when checking the self-contained self-rescuers for leaktight.
