1. Technical data

Construction: flush-mounted part is made of plastics or steel sheet, wall-mounted part (doors)

white, powder coated, equipped with the lock with the emergency

unlocking, inlet and outlet of gas from the top.

Pressure: compressed gases 0 – 10 bar

vacuum 0 - -0.9 bar

Weight Outer dimensions (WxHxD)

SZI-1 4.5 kg 380x450x90

SZI-2 6.1 kg 380x450x90

SZI-3 7.3 kg 380x450x90

SZI-4 10.5 kg 560x480x90

SZI-5 14.2 kg 560x480x90

SZI-6 15.4 kg 560x480x90

Power supply: 12V DC, 0.1A

Assembly: Flush-mounted or wall-mounted in a housing

 Pressured inlets/outlets from the top: copper pipe 15x1.

 Vacuum inlets/outlets from the top: copper pipe 15,18,22x1 or according to the design.

 Optionally only informative inlets.

The box is equipped with a system of analog pressure converters 0-5V and built-in gas monitor. Too

high or too low level or excessive gas consumption is signaled optically and acoustically (break-down

consisting in damage of the distribution conduits or the medical equipment).

1.1 Information about the device

 Device should be stored in a dry place in temperature between +10 C - +45 C.

 The valve box is a part of a central gas supply system according to EN ISO 7396-1. The pipes

in the pipeline must by hard soldered.

 The valve-informative box, according to 93/42/EWG directive and the decree of the Minis-

try of Health, Journal of Laws No 16 item 74 dated January 12, 2011 is a medical manufac-

tured product – class IIb.

2. Application

For monitoring pressure of medical gases and vacuum for hospital units, operating theatres, ICU

rooms in central gas supply systems. Possibility of transmitting information to the central alarm unit

or central computer.

3. Construction

The housing of the valve box contains up to 6 shut-off valves, analog pressure converters 0-5V,

emergency supply point type NIST and gas alarm unit with LCD display mounted on the doors.

4. Installation

 Wall mounting of the housing – the doors should be disassembled prior to the assembly.

 Connection of copper pipes to the main system.

 Before start-up of the installation the doors should be assembled again.

 Supply the 12V DC voltage to a box.

 Connect „+” and „-” poles to marked pins.

!!! Attention !!!

Mounting must be performed ONLY by qualified technicians experienced in servicing

medical equipment.

Read manual before mounting valve box.

!!! Attention !!!

Polarity of the connection is very important, any mistake causes a damage of the electronic

system

!!! Attention !!!

Before performing a leak test vacoumeter should be removed.

 Perform leak test of pipeline system in accordance with the EN ISO 7396-1;

5. Operation

5.1 First start-up

1. Before start-up make sure all tests in accordance with EN ISO 7396-1 finished successfully.

2. Slowly open each valves in box;

3. Make sure that pressures in manometers are as determined by project;

4. Connect power supply;

5. Make sure that alarm unit shows correct informations (gas type and pressure);

6. Device is ready to use.

In order to use shut-off valves, the doors must be opened.

The box may also be opened without a key in case of an emergency. This is done by pushing the lock

with the plastic mounting into the box. Upon completion of the necessary steps, the plastic mounting

fixing the lock should be replaced and put back in the door. Close the door with a key.

According to EN ISO 7396-1, the valve box is equipped with the physical unsealing. For this purpose

the relevant shut-off valve must be closed, the pipeline behind the valve should be emptied. Then,

physical cut-off may be unscrewed and screwed in again after the works.

For the emergency supply, NIST connectors should be used. They are encoded for the given

gas. NIST connectors together with the pressure reducer should be mounted on the emergency bottle

with compressed gas, placed in proper socket, pushing it in and screwing down the pin cap. Before

opening of the valve of the bottle, it is required to loosen reducer’s hand wheel. After slow opening

of the valve of the bottle the pressure on the reducer may be set as per working pressure in the instal-

lation.

6. Maintenance / repair

Each valve box must be subjected to maintenance at least once a year. In particular, it is re-

quired to check the shut-off valves and points of emergency supply and check the tightness of the

pressure connections inside the box. Any repairs may only be performed by a qualified personnel.

Use only genuine parts of HYDRO-GAZ-MED Sp.j.

8. Alarm system

8.1 Alarm unit mounted in valve box

Functions: transmission of data to the remote alarm unit and display of information on the status of

the monitored gases together with visual and audio alarm status.

Power input: < 750mW

Length: 148 mm

Width: 80 mm

Height: 41 mm

Weight: ca 165 g

Screen overview

For each gas its pressure is displayed with the accuracy of a tenth of a bar. In case the pressure of any

of the gases is lower than this user-defined in the program, the name of the gas and red diode start to

blink, and the sonic alarm activates. The sonic alarm may be switched off for a period of 15 minutes

by pressing a button. If the pressure of a gas is higher than the user-defined in the system, the name

of the gas and green diode start to blink, and the sonic alarm activates. The sonic alarm may be

switched off for a period of 15 minutes by pressing a button.

9. Remote alarm unit

9.1 Under plaster version

Functions: displays informations on a status of monitored gasses together with visual and audio

signalling the alarm status. The remote alarm unit operates identically as the alarm unit

mounted in the valve box.

Power input: < 100 mA

Length: 180 mm

Width: 90 mm

Height: 42 mm

Weight: ~ 200 g

9.2 Remote alarm unit – on wall version

Alarm unit is equipped in touchscreen. On the screen there is TEST buton, which should be

weekly used to check functioning of alarm unit.

On the housing we have dual color LED from visual signal. In case of alarm the LED blinks;

green light when pressure is to high, and red light when pressure is to low.

With each visual signal there is also audio signal.

To mute the audio signal we need to touch the bell symbol on the screen. After 15 minutes, if

the cause of the alarm was not removed, audio signal returns. It will be returning till cause of the

alarm will not be gone.

During normal work green is LED is constantly ON.
