For many laboratories it is for ISO, or other purposes, necessary to validate that the incubators
are running correctly. The MIRI GA®gives these validation capabilities in a simple to use
package.
Correctly connected to a PC the logging software will document parameters and send e-mail
alarms if set up.
This product fulfills the requirements of EN 61010-1:2010 Safety requirements for electrical

8 Getting started
•Follow the guidelines in the safety instructions and warnings section;
•Connect the mains cable to mains outlet;
•Connect the mains cable to the MIRI GA®;
•Connect the gas sample lines;
•Switch on the MIRI GA®on the back;
•Observe for normal functionality;
•Follow the guidelines in the Validation Guide;
•Complete user training and instructions.
Clean the device before use if the device is in a clinical setting. It is not delivered
sterile or in clinically acceptable cleanliness state. Consult the cleaning instructions section
in this manual for the manufactures recommended guidelines.
9 Mains connection
The MIRI GA®comes with a detachable mains power cord. The power cord is prepared for the
country in which the unit is intended to be used in.
Do not defeat the safety purpose of the grounding-type plug. A grounding type plug
has two blades and a third prong is provided for your safety. If the provided plug does not
fit into your outlet, consult an electrician for replacement of the obsolete outlet.
The power requirement is: 230V 50 Hz OR 115V 60Hz.
The built-in power supply is of a “switch mode type”that automatically adjusts to the correct
mains power between 100V-250VAC 50-60 Hz.
Figure 9.1 Power supply
10 Gas connections
10.1 Placement of gas connections
On the back of the unit there is one gas outlet and on the side 6 inlets.

CO2/O2Gas and temperature Validation unit MIRI GA®Use Manual Rev. 2.0
13
Figure 10.1 Gas outlet
Figure 10.2 6 x gas inlets
10.2 Gas without loop
The MIRI GA®can be connected to a sample spot through one or all of the 6 ports on the side.
If the circuit is not looped, the exit on the back of the MIRI GA®leads the gas sampled into the
room.
If the sample are drawn from a MIRI®CO2/O2 incubator, it is important to loop the
circuit in order to make it possible for the MIRI GA®to draw out a sample, of what will
otherwise be an almost air tight place.
The pump of the MIRI GA®cannot generate a pressure, thus any sample circuit
must be free flowing. Loop the circuit if the MIRI GA®has to sample from an airtight
area.

CO2/O2Gas and temperature Validation unit MIRI GA®Use Manual Rev. 2.0
14
10.3 Gas connection with loop
Figure 10.3 MIRI GA®connections with incubator
In Figure 10.3, sample ports 1 and 2 are connected to the sample ports on a MIRI®CO2/O2
incubator and the exit port to the special port in the VOC/HEPA filter. In this way the gas sample
taken out is lead back into the system and it is possible to sample from an airtight area and there
will be no loss of gas to the room or the environment.
