Intended Use - GCE MM90 STANDBY Bedienungsanleitung

ENGLISH
INSTRUCTION FOR USE: MM90 STANDBY
1. FOREWORD
These instructions for use cover essential information for the entire life cycle of the manifold:
• Installation,
EN
• Operation and bank changeover,
• Alarm conditions,
• Maintenance,
• Cleaning,
• Disposal.
GCE Medical central gas system is medical device classifi ed as class IIb according
to the Medical 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.

2. INTENDED USE

The MM90 STANDBY medical gas manifold is intended for use in hospital pipeline system
as backup medical gas source. Together with MM90 shall always be used alarm providing all
alarms according to standard (like Gas alarm).
As 2nd stage is recommended to use a line pressure regulator.
This instruction for use details the operational and safety procedures for the MM90 manifold.
The MM90 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 diffi culty of the manifold. These diffi 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!

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.
** 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.
The marking to be read on the regulator or manifold product label refer to max settled cylin-
der pressure not developed cylinder pressure, this should match the pressure marking on the
cylinder.
