2. INTENDED USE

The MM40 – HP UNIT semiautomatic medical gas manifold is intended for use in hospital

pipeline system as medical gas source and gas pressure reducing unit. Together with

the medical gas manifold shall always be used alarm providing all alarms according to

EN ISO 7396-1 and comply with EN 60601-1 standards. A medical stabilizer (LINE REGULATOR

or MM40 - STABILIZER) can be used together with MM40 – HP UNIT to reduce the pressure

to hospital distribution pressure. The medical stabilizers must be installed according to EN

ISO 7396-1 and EN 60601-1 standards. For more information about accessories (Gas Alarm or

stabilizer) read instruction for use attached to the speciﬁc product.

This instruction for use details the operational and safety procedures for the MM40 – HP UNIT.

The medical gas 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.

snížení tlaku, který je distribuován do distribučního systému nemocnice. Medicinální stabilizér

musí být instalován v souladu s normami EN ISO 7396-1 a EN 60601-1. Pro více informací o

příslušenství (Gas Alarm nebo Stabilizer) čtěte návod k použití pro daný produkt.

Tento návod k použití detailně popisuje provozní a bezpečnostní postup pro použití stanice

MM40-HP UNIT. Medicinální rozvodová stanice je k dispozici pro kyslík, oxid dusný*, a stlačený

vzduch, může být také použita pro oxid uhličitý*, dusík a směs plynů pro medicinální aplikace.

Tato stanice je navržena pro provoz při maximálním tlaku 200 bar**.

Poznámka: Oxid dusný a Oxid uhličitý jsou kapalné plyny. Tyto plyny se při expanzi extrémně

ochlazují a mohou způsobovat zamrzání redukčního ventilu. Je nutno instalovat ohřívače na

obě strany medicinální redukční stanice (celkem 2 ohřívače na redukční stanici).

Před použitím čtěte návod k použití. Vždy tyto instrukce dodržujte!

Obrázky v tomto návodu k použití jsou pouze informativní. Skutečný produkt se může lišit dle

dané varianty produktu a / nebo nemusí obsahovat všechny části popsané níže. Vždy čtěte

přílohu č. 1 - technická data.

* Redukční stanice musí být instalována v místnosti s minimální teplotou 10°C.

** Maximální provozní tlak je 200 bar myšleno pro použití s lahvemi naplněnými na maximální

ustálený tlak 200 bar (při 15 °C). Při vyšších teplotách lahvový tlak přesáhne hodnotu 200 bar.

Například lahvový tlak Kyslíku při teplotě 50 °C je 240 bar. Tlak vyznačený na štítcích redukčních

ventilů i redukčních stanicích značí maximální ustálený tlak v lahvích, nikoliv vyvíjený tlak v

lahvích, toto by mělo být shodné s maximálním tlakem označeným na lahvích
