Leakage Test - GCE MediFlowTec Notice D'instructions

In accordance to Article 33 of REACH GCE, s.r.o. as responsible manufac-
turer shall inform all customers if materials containing 0.1% or more of sub-
stances included in the list of Substance of Very High Concern (SVHC).
The most commonly used brass alloys used for bodies and other brass
components contain 2-3% of lead (Pb), EC no. 231-468-6, CAS no. 7439-
92-1. The lead will not be released to the gas or surrounding environment
during normal use.
After end of life the product shall be scrapped by an authorized metal re-
cycler to ensure e cient material handling with minimal impact to environ-
ment and health. To date we have no information that indicates that other
materials containing SVHC of concentrations exceeding 0.1% are included
in any GCE product.
8.2. SERVICE, REPAIRS AND MAINTENANCE
8.2.1. SERVICE
GCE recommends that a product periodic inspection is undertaken at least
once a year to do leakage test and check proper functionality of the fl ow
selector.

8.2.2. LEAKAGE TEST

• After connection to medical gas pipeline system terminal unit or to medi-
cal regulator, visually check possible leakages:
LEAKAGE TEST OF THE FLOW SELECTOR FOR FLOW ADJUSTMENT:
1. Adjust by handwheel the value „0". When closing don´t use excessive
torque.
2. Connect the fl ow outlet and hose nipple with a hose, the end of the
hose immerse into a jar fi lled with water.
3. Connect the fl ow selector to the source of compressed air max. 5 Bar.
4. The test: leave the fl ow selector 1min under pressure. Number of
bubbles shall not be higher than 3 bubbles per 1 min.
5. When test ready, disconnect the fl ow selector from the source of
compressed air.
EXTERNAL LEAKAGE TEST:
1. Adjust by handwheel of the fl ow selector the value „0". When closing
don´t use excessive torque.
2. Close the outlet connection of the fl ow selector using a plug, the plug
has to have the same thread as the outlet connector of the fl ow selector
or, in the case the hose nipple used, use the hose with blind plug.
3. Connect the fl ow selector to the source of compressed air max. 5 Bar.
4. Adjust by handwheel of the fl ow selector the maximal value. When
opening don´t use excessive torque.
5. Possible leakage you will detect by application of soap water on
product joins.
6. After test disconnect the fl ow selector from the source of compressed
air, remove the plug from outlet connection and carefully clean the
surface of the fl ow selector, see chapter 7 (cleaning).
