AB

The manifolds covered by these instructions are designed to allow equal numbers of cylinders

to be manifold together to give an operating bank and a reserve bank. The operating bank will

deliver gas to the manifold pressure regulator until the cylinders are exhausted. At that point the

supply will switch to the reserve bank and the exhausted bank can be replenished. The object

is to give uninterrupted gas supply.

The manifold consists of two manifold pressure regulators A&B, a shuttle valve C, two inlet shut

o valves D & E and two purge valves F & G. Pressure gauges I & J are ﬁtted to the inlet side

downstream of D & E. They show the contents pressure of the two cylinder banks. An extra

gauge K, is also ﬁtted to show the outlet pressure. Pressure switches are ﬁtted to the inlet

downstream of D & E to indicate leaking reserve side and change of operating side. Pressure

switches are also ﬁtted to the shuttle C to indicate high (“H” marking) and low (“L” marking)

outlet pressures. Two proximity switches are ﬁtted to the shuttle C to indicate which bank is

in operation and it also decides which side is monitored for leaking reserve. The pressure

switches and the proximity switches shall be connected to an alarm panel to give a visual and

audible indication of the condition of the manifold. GCE recommend the use of gas alarm (see

chapter 12 - Accessories). The gas will exit the manifold through the outlet connection H.

6. INSTALLATION

* Manifold must be installed, the parameters should be set and tested in a room with a minimum

temperature of 10 °C. It is used according to the operating conditions listed in Chapter 3.

It is necessary that an installer of the product is trained and has an appropriate licence ac-

cording to national standards. It is outside the scope of these operating instructions to give

detailed guidance on installations.

The installation must conform to the standard MEDICAL GAS PIPELINE SYSTEMS EN ISO

7396-1 as amended. All tests according this standard have to be fulﬁlled.

When working with medical gases it is essential that no oil or grease come into contact with

the gas. This means that hands, tools and work clothes be free from oil or grease before any

work is undertaken. Components used for service must be gas compatible. For oxygen ser-

vice must also be degreased and although they will reach you in this condition care must be

taken during storage and handling.

7.1. START UP OF MANIFOLD

• Check both shut o valves D & E are closed.

• Check both purge valves F & G are closed.

• Open valve D slowly, left side will hereby become the operating side and start to supply gas

at a pressure of 9 bar through the outlet connection H. The cylinder pressure can be read on

the inlet gauge I and the outlet pressure on gauge K.

NOTE: Two proximity switches are ﬁtted to the shuttle valve to electrically indicate which side

is in operation and it also decides which side is monitored for leaking reserve.

• Check all connection for leaks using a 0.5% teepol / water solution.

• Open valve E slowly. This will become the reserve side. The cylinder pressure of the reserve

bank can be read on inlet gauge J.

• The system is now supplying gas, with the left hand bank in operation and the right hand

bank on reserve. While gas is ﬂowing, the pressure in the operating side will fall. This will be

indicated on the inlet gauge I.

7.2. BANK CHANGE OVER

At a pre-determined pressure of 7 bar the pressure from the reserve bank will push the piston

over in the shuttle valve and reserve bank will take over from the near empty bank of cylinders.

You will have an alarm “Change of operating side / Leakage on reserve side”. (see Chapter

8 – Alarm conditions).

9/64

EN

7.2.1. LEFT HAND LH SIDE EMPTIED

• The inlet pressure gauge I on the left-hand side is indicating exhausted cylinders, so the left-

hand bank of cylinders needs to be replaced.

• Close shut-o valve D and the isolating valves on the empty cylinders or cylinder bundles.

• Open purge valve F to vent any excess gas within the high pressure hose.

• Close purge valve F and disconnect high pressure hose from cylinders or cylinder bundles.

• Re-place empty cylinders with full ones.

• Re-connect high pressure hose to cylinders or cylinder bundles.

• Open cylinder valves slowly and leak test joints with 0.5% teepol in water solution.

• Open shut-o valve D and read the full content of the new cylinders on the inlet gauge I. The

alarm condition “Change of operating side / Leakage reserve side” will hereby be cancelled.

• The left hand side is now the reserve bank with full cylinders.

7.2.2.RIGHT HAND RH SIDE EMPTY

Repeat operation above for right hand bank to give an uninterrupted gas supply.

7.3. SHUT DOWN

• For short term (hours) shutdown close shut-o valves D & E.

• For long term (days) shutdown close shut-o valves D & E and the cylinder isolating valve.

8. ALARM CONDITIONS

8.1. ALARM PROCEDURE

On signal of alarm condition the appropriate visual indicator is illuminated on the gas alarm.

The alarm condition should be recorded and the necessary action taken, as detailed in the

sections below.

8.2. STATUS INDICATED BY ALARM

8.2.1. CHANGE OF OPERATING SIDE/ LEAKING RESERVE

If gauge I or J shows less than 140 bar (50 for N2O) you have alarm “Change of operating side”.

If gauge I or J shows more than 140 bar (50 for N2O) you have alarm “Leaking Reserve”.

Change of operating side actions:

• Replace the empty cylinders with full cylinders as described in chapter 7.

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

Leaking Reserve actions:

• Allocate the leakage using leak detecting spray. Isolate the leaking area and do repair/change

component or washer.

8.2.2. HIGH SUPPLY PRESSURE

• Check that the regulator outlet pressure is as preferred. If not, reset the regulator by turning

regulator screw.

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

most likely has internal leakage. Replace the regulator with a new or refurbished unit.

8.2.3. LOW SUPPLY PRESSURE

• Check that the regulator outlet pressure is as preferred. If not, reset the regulator by turning

regulator screw.

ções, controlos e precauções de segurança.

É o dever de todos os funcionários fornecer toda esta informação, formação e supervisão

segundo as normas nacionais, devido à necessidade de garantir a saúde e a segurança de

todos os funcionários.

5. DESCRIÇÃO DO PRODUTO

As centrais indicadas nestas instruções são projectadas para equipar um número suﬁciente de

cilindros para poder ter uma parte para abastecimento e outra de reserva, ao mesmo tempo. A

central vai fornecer gás a partir do lado operacional ao regulador de pressão até que a garrafa

se esgote. Nesse momento, o fornecimento de gás vai passar para o lado da reserva e o lado

esgotado pode ser substituido. O objectivo é manter um abastecimento ininterrupto de gás.

A central consiste de 2 reguladores de pressão A e B, válvula de inversão C, duas válvulas

de corte nas entradas D & E e duas válvulas de purga F & G. Manómetros de pressão I e J

estão montados na entrada D e E e marcam o conteúdo da pressão de ambos os lados das

entradas de garrafas. Outro manometro é montado sobre a válvula inversora C para indicar a

pressão de saída. Sensores de pressão estão montados sobre as entradas D e E para indicar

o lado de reserva. Há também sensores de pressão montados em contacto com a válvula

C para indicar a alta (marcado “H”) e a baixa (marcado como “L”) pressões de saída. Dois

contactos de proximidade estão montados sobre a válvula inversora C para indicar que lado é

que está a funcionar como backup. Os sensores de pressão e os contatos proximidade devem

ser conectados à caixa de alarme para dar um alarme visual e sonoro. Para o uso de alarmes

(ver Capítulo 12 - Acessórios).

6. INSTALAÇÃO

* A central deverá ser instalado, os parâmetros devem ser conﬁgurados e teste em uma sala

com temperatura mínima de 10 °C. É usado de acordo com as condições operacionais listadas

no Capítulo 3.

Não é o objectivo destas instruções de uso dar indicações detalhadas sobre como instalar

a central. É aconselhável que um instalador qualiﬁcado e reconhecido seja utilizado para

realizar a instalação.

É aconselhável que esta esteja de acordo com a norma EN ISO 7396-1 (sistemas e instalações

de gases medicinais). All tests according this standard have to be fulﬁlled.

19/64

PT

É extremamente importante que ao trabalhar com gases medicinais não exista nenhum con-

tacto do gás com óleos ou gorduras. Isso implica que as mãos, ferramentas e roupas devem

estar limpas de óleo ou gordura antes de iniciar qualquer operação. Todos os componentes

devem ser compatíveis com o gás. Para o O2 tem de vir desengorduradas, e mesmo assim

tem que tomar as devidas precauções durante a armazenagem e funcionamento.

6.1. FIXAÇÃO À PAREDE

Consulte o fabricante ou projectista para a colocação da central de gás. Montar a central à

altura desejada, conforme necessario.

Veja abaixo os oriﬁcios utilizados para montar a central.

Notar que apenas os parafusos do topo suportam todo o peso da central. Escolha os parafu-

sos do tamanho correcto a usar.

6.2. CONEXÃO DE SAIDA

Tubo de soldar de diámetro 22 mm.

6.3. VÁLVULA DE SEGURANÇA E AS SAÍDAS DAS PURGAS

Tubo de soldar 10 mm. Os tubos para a válvula de segurança e de purga podem (usando um

ligador tipo T) ser soldados juntos e ter a mesma saida para fora da instalação.

6.4. LIGAÇÃO DE PIGTAILS / FLEXÍVEÍS DE ALTA PRESSÃO / LIRAS /

COLECTORES

Aperte à entrada da central os ﬂexíveis de alta pressão. Assegure-se que as válvulas de corte

(D & E) e as válvulas de purga (F & G) estão fechadas.

Abrir lentamente uma garrafa de um lado da central.

Veriﬁcar se há fugas entre a conexão de entrada e os ﬂexíveis de alta pressão usando o

gazobul B140303.

Abra lentamente as restantes garrafas caso não existam fugas.

Repita a mesma operação do outro lado da central.

20/64

PT

Nota: Se houver qualquer fuga entre colectores / ﬂexíveis de alta pressão e entradas da

central, veriﬁque se ajunta de vedação está corretamente posicionada e que está presente.

6.5. CONECTAR A FONTE DE ELECTRICIDADE

A ligação deve ser feita por pessoal qualiﬁcado para instalações eléctricas.

Siga as instruções para o alarme de gás.

O dispositivo deve ser conectado a terra atraves do parafuso.

7.1. PREPARAÇÃO DA CENTRAL PARA O SEU FUNCIONAMENTO

• Veriﬁque se as duas válvulas de corte D e E estão fechadas.

• Veriﬁque se as duas válvulas de purga F e G estão fechadas.

• Abrir lentamente a válvula D, e o lado esquerdo passa desta maneira a ser o lado de

abastecimento. A pressão do cilindro é indicado no manómetro I, e a pressão de saída no

manómetro K.

NOTA: Dois contactos de proximidade estão montadas sobre a válvula C para indicar qual o

lado que está operacional e qual é o lado referido como o lado de reserva.

• Veriﬁque todas as conexões contra possíveis fugas.

• Abrir lentamente a válvula E. Este será o lado de reserva. A pressão da garrafa de reserva é

indicada no manómetro J.

• A central fornece gás a partir do lado operacional (esquerdo) e mantem o lado direito como

reserva. Logo que haja ﬂuxo de gás, a pressão do lado operacional descerá. Isto sera indicado

no manómetro de entrada I.

7.2. MUDANÇA DO LADO DO ABASTECIMENTO

A uma pressão predeterminada de 7 bar, a pressão do gás do lado da reserva empurrara o

pistão da válvula inversora e o lado de reserva passa a ser o lado de abastecimento. Será dado

um alarme “Mudança do lado de abastecimento.” (Veja o Capítulo 8 - estados de alarme.
