GCE Medical central gas system is medical device classiﬁ ed as class IIb according to the Medi-

cal Device Directive 93/42/EEC.

Their Compliance with essential requirements of 93/42/EEC Medical Device Directive is based

upon EN ISO 7396-1 and EN 60601-1 standards.

2. INTENDED USE

The MC25 semiautomatic medical manifold is intended for use in hospital pipeline system as

medical gas source. Together with MC25 shall always be used alarm providing all alarms ac-

cording to standard EN ISO 7396-1.

This instruction for use details the operational and safety procedures for the MC25 manifold.

The MC25 manifold is available for Oxygen, Nitrous Oxide* and Compressed Air, it can also be

used for Carbon Dioxide*, Nitrogen, and gas blends for Medical Applications. These manifolds

are designed to operate at a maximum service pressure of 200 bar**.

Note: In Nitrous Oxide and Carbon Dioxide there is humidity due to the common production

methods, the mounting of a pre-heater per bank (total 2 pre-heaters per manifold) eliminates

possible working di culty of the manifold. These di culties are due to the fact that the gas,

when expanding, tends to produce ice.

Read this instruction before use of the product. Always follow this instruction!

The product shall only be used for the purpose described in this instruction!

The product must be installed by a qualiﬁ ed person and by compliance of all requirements of

EN ISO 7396-1 as amended!

used with the product, so that data and performance comply with the intended use of the

product!

The product must not, under any circumstances be modiﬁ ed by other than the manufacturer!

The product must not be used for di erent gas than stated on the label.

* Manifold shall be installed in room with minimal temperature of 10 °C.

** Maximum service pressure of 200 bar means for use with cylinders ﬁ lled to a maximum set-

tled pressure of 200 bar (at 15 °C). At higher temperatures cylinder pressure will exceed 200 bar

(developed pressure). For example developed pressure for oxygen at 50 °C is 240 bar.

regulators by closing valve V3 and check one regulator at a time. Be sure that the valve V4

is set to the same operation side as lever L1. Start with the regulator on reserve side, relief

the pressure by the safety valve S1 & S2 and check if the pressure increases again. Change

operating side and make the same test with the other regulator.

• If you shortly after resetting the regulator have the same alarm condition again, the regulator

most likely has internal leakage. Contact authorised service to replace the regulator with a

new or refurbished unit.

• Check that the audible and visual alarms on the Gas alarm have been cancelled.

8.2.4.HIGH DISTRIBUTION PRESSURE

The alarm starts in following situations:

Distribution pressure is too high

• Check that the distribution pressure is as preferred. If not, isolate the regulators R3 & R4 by

closing valve V3 and check one regulator at a time. Be sure that the valve V4 is set to the

same operation side as lever L1. Start with the regulator on reserve side, relief the pressure

by the safety valve S3 & S4 and check if the pressure increases again. Change operating side

and make the same test with the other regulator.

• If you shortly after resetting the regulator have the same alarm condition again, the regulator

most likely has internal leakage. Contact authorised service to replace the regulator with a

new or refurbished unit.

• Check that the audible and visual alarms on the Gas alarm have been cancelled.

8.2.5.LOW DISTRIBUTION PRESSURE

The alarm starts in following situations:

Distribution pressure is too low

• Check the high pressure gauges M5 & M6, if the valves V5 & V6 and cylinders valves are

open, if the cylinders are not empty or if there is not a leakage. In this case replace cylinders

or make corrections on collection pipelines.

• Check the intermediate pressure gauges M1 & M2, if the valves V1 & V2 and V3 valves are

open or if there is not a leakage. In this case follow procedure as Intermediate pressure is

too high.

13/123

2. AVSEDD ANVÄNDNING

MC25 är en halvautomatisk medicinsk gascentral avsedd att användas i sjukhusets rörledn-

ingssystem som försörjningsenhet av medicinska gaser. MC25 skall alltid övervakas av gaslarm

enligt standard EN ISO7396-1.

Dessa instruktioner innehåller detaljerade handhavande och säkerhets anvisningar för gascen-

tral MC25. MC25 ﬁ nns för Oxygen, Lustgas N2O, A-luft, Instrumentluft, och kan även användas

till Koldioxid CO2, Nitrogen och gasblandningar för medicinska applikationer. Dessa gascen-

traler är designade för ett maximalt inloppstryck på 200 bar.**

Anmärkning: Lustgas och koldioxid är kondenserade gaser. Dessa gaser kyls ned extremt

vid expansion och kan medföra tillfrysning av reduceringsventilen. Värmare kan installeras

på den medicinsktekniska reduceringsenhetens båda sidor (totalt två värmare per reduce-

ringsenhet).

Läs denna instruktion före användning av produkten. Följ alltid instruktionerna!

Bilderna i denna anvisning är endast av informativ karaktär. Den verkliga produkten kan skilja

sig från den avbildade beroende på produktvariant och/eller behöver inte nödvändigtvis in-

nehålla samtliga de detaljer som beskrivs nedan. Läs alltid igenom bilaga nr. 1 - tekniska data.

* Reduceringsenheten skall alltid installeras i utrymmen som har en lägsta temperatur om 10°C.

** Maximalt inloppstryck om 200 bar avser nominellt tryck vid användning av gasﬂ askor fyllda

till ett maximalt tryck om 200 bar (vid 15 °C). Vid högre temperaturer överstiger ﬂ asktrycket 200

bar. Som exempel är trycket hos syrgas 240 bar vid en temperatur om 50 °C.

Det tryck som anges på märkningar hos reduceringsventiler och reduceringsenheter avser

maximalt nominellt ﬂ asktryck, inte det tryck som utvecklas i ﬂ askorna, vilket skall vara lika med

det maximala tryck som gasﬂ askorna är märkta med..

3.1.DRIFTSSÄKERHET

Den gascentral som beskrivs nedan i denna anvisning, är avsedd för användning med tryck-

ﬂ askor och nedanstående allmänna åtgärder innehåller våra rekommendationer för säker och

eﬀ ektiv förvaring och användning av komprimerade gaser.

3.1.1.FÖRVARING AV TRYCKFLASKOR

Förvaringsutrymmet för tryckﬂ askor skall vara konstruerat i enlighet med gällande normer.

Nedan ﬁ nns ett antal rekommendationer:

• välventilerat utrymme som skyddas mot väder och vind.

• Utrymmet skall vara brandskyddat. Se till att hålla utrymmet bortom värmekällor och öppen

eld. Märk utrymmet med ”Rökning förbjuden”.

• Märk gasförrådet med lämplig varningsmarkering (ex.vis brandfara, gift, etc.)

• Håll utrymmet rent och se till att endast behörig personal har tillträde.

• Se till att lämpliga skyddshjälpmedel (ex.vis brandsläckare, andningsutrustning, o.dyl.) ﬁ nns

5. PRODUKTBESKRIVNING

Gascentralerna som beskrivs i denna instruktion är designade för att ansluta samma antal gas-

ﬂ askor på båda sidor, en för driftsida och en för reservsida. Centralen kommer att leverera gas

från driftsidans ﬂ askpaket till regulatorerna tills ﬂ askorna är tomma och trycket sjunker till ett

förinställt värde. Då kommer gas försörjningen att växla över till reservsidan och de tomma

ﬂ askorna kan bytas ut. Syftet är att ge en avbrottsfri gasförsörjning.
