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

2. INTENDED USE

The MC80 semiautomatic medical manifold is intended for use in hospital pipeline system

as manifold pressure regulators. Together with MC80 shall always be used alarm providing all

alarms according to standard EN ISO 7396-1.

This instruction for use details the operational and safety procedures for the MC80 manifold.

The MC80 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 inlet 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 qualiﬁed person and by compliance of all requirements of

most likely has internal leakage. Contact authorised service for 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 OP.PRESSURE LOW

The alarm starts in following situations:

Distribution pressure is too low

• Check the high pressure gauges M1 & M2, if the valves V13 & V14 and cylinders valves are

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

make corrections on collection pipelines.

• Check the intermediate pressure gauges M3, if the valves V1 & V2 and V3 & V4 valves are

open or if there is a leakage. In this case follow procedure as Intermediate pressure is too

high.

• Check the distrubution pressure gauge M4, if the valve V7 & V8 is in correct position or

if there is a leakage. In this case reset regulators R5 & R6 one at a time by releasing the

pressure with the safety valves S3 & S4, start with the reserve side. Check if the pressure

comes back to normal, if not increase the distribution pressure by turning the regulator R5

& R6 screw and check again. If the distribution pressure is still low, contact authorised service

for replace the regulator with a new or refurbished unit.

1. VOORWOORD

Deze gebruiksaanwijzing bevat belangrijke informatie voor de volledige levensduur van het

spruitstuk:

• Installatie,

• Gebruik en wisseling van rijen,

• Alarmtoestanden,

• Onderhoud en reiniging,

• Afvoer.

Het GCE medisch centraal gassysteem is een medisch apparaat dat is ingedeeld in klasse IIb

volgens de Richtlijn Medische Apparatuur 93/42/EEG.

De naleving van belangrijke eisen uit Richtlijn Medische Apparatuur 93/42/EEG is gebaseerd

op de normen EN ISO 7396-1 en EN 60601-1.

2. BEOOGD GEBRUIK

Het MC80 semi-automatische medische spruitstuk is bedoeld voor gebruik in pijpleidingen in

ziekenhuizen als verdeelstukdrukregelaars. In combinatie met de MC80 moet altijd een alarm-

systeem worden gebruikt dat alarmen afgeeft overeenkomstig de norm EN ISO 7396-1.

Deze gebruiksaanwijzing beschrijft de bedienings- en veiligheidsprocedures voor het MC80-

spruitstuk. Het MC80-spruitstuk is beschikbaar voor zuurstof, stikstofoxide* en perslucht. Het

kan ook worden gebruikt voor koolstofdioxide*, stikstof en gasmengsels voor medische toe-

passingen. Deze spruitstukken zijn ontworpen om te worden gebruikt bij een maximale inlaat-

druk van 200 bar.**

Opmerking: In stikstofoxide en koolstofdioxide is vocht aanwezig vanwege de gebruikte pro-

ductiemethoden. Door voor elke rij een voorverwarmer te monteren (in totaal twee voorver-

warmers per spruitstuk) wordt de correcte werking van het spruitstuk gewaarborgd. Dit prob-

leem wordt veroorzaakt door het feit dat het gas bij het uitzetten tot ijsvorming kan leiden.

Lees deze gebruiksaanwijzing voordat u het product gaat gebruiken. Neem altijd de aanwij-

zingen in acht!

Het product mag uitsluitend worden gebruikt voor het doel dat in deze gebruiksaanwijzing

wordt vermeld!

Het product moet worden geïnstalleerd door een gekwaliﬁceerde persoon en met inachtne-

ming van alle eisen uit EN ISO 7396-1 zoals geamendeerd!

Om de veiligheid van de patiënt te garanderen, moeten vóór het gebruik de apparatuur en

accessoires bij het product worden gecontroleerd, zodat de gegevens en prestaties overeen-

komen met het beoogd gebruik van het product!

Het product mag in geen geval worden aangepast door iemand anders dan de fabrikant!

Het product mag uitsluitend worden gebruikt voor het gas dat wordt vermeld op het etiket.

Aeeldingen in deze gebruiksaanwijzing dienen alleen ter informatie. Aankelijk van de

variant van het product kan het echte product er ietwat anders uitzien en mogelijk behoren

sommige van de hieronder beschreven onderdelen niet tot de levering. Raadpleeg altijd bij-

lage nr. 1 voor technische gegevens.

* Spruitstuk moet worden geïnstalleerd in een ruimte met een minimale temperatuur van 10°C.

** De maximale bedrijfsdruk van 200 bar geldt voor het gebruik van cilinders die zijn gevuld tot

een maximale druk van 200bar (bij 15°C). Bij hogere temperaturen zal de cilinderdruk boven

200bar komen (ontwikkelde druk). De ontwikkelde druk bij 50°C bijvoorbeeld is 240bar.

De markering op het productetiket van de regelaar of het spruitstuk betreft de maximale cilin-

derdruk; deze waarde moet overeenkomen met de drukmarkering op de cilinder.
