•
Fasten the push plate (2) with the circlip (1).
•
Test the function of the coupling by connecting a dosage device with a male
coupling. The coupling should only release its grip when the push plate (2) is
pressed inwards.
6.3. TEST AFTER THE CARRYING OUT OF INSTALLATION
6.3.1. TEST OF FUNCTIONALITY AND LEAKAGE TEST AFTER THE
END OF INSTALLATION
•
For the test of functionality and leakage test use the gas for which the
terminal unit is intended or the medical air or nitrogen with pressure as
specified in Chapter 2.
•
Test the connectivity of counterparts of all installed terminal units, for
variants with the positioning of a counterpart of the quick connector
verify the right orientation of the quick connectors.
•
Test the through-pass capacity of the terminal unit for presence of gas
on the outlet.
•
Test the general tightness of the terminal unit and with all accessories
in the state with connected as well as disconnected counterparts of the
quick connectors. The leakage must not exceed 0.296 ml/min in any of
the described conditions (this corresponds to a change in the pressure
0.03 kPa.l/min for the leakage test for a pressure drop).
•
Clean the terminal unit from possible impurities and check the integrity
and presence of all labels and markings.
Installation and testing procedures must be in compliance with EN ISO
7396-1 and EN ISO 5359 standards.
7. OPERATIONS
7.1. BEFORE OPERATION
7.1.1. PREPARATION FOR USE OF TU
•
Check if the TU (including label) does not show any visible external
damage. If there are signs of external damage, ensure the unit is not
and label. Contact the responsible personnel and call service - see
chapter 9.2.
•
Check visually if the product is clean, if cleaning is needed follow pro-
cedures described further in this instruction for use.
TU can be used only for the gas specified on the cover. Never try to use
it for different type of gas.
