Choose a suitable location to install the SEU.Fix the panel holder on the wall at the recommended height of
about 0.45m (1.5 feet) from the floor and as close to the manifolds and valves as possible.
Put the SEU on the panel holder,making sure the connection is tight.
Fix another panel holder in a suitable location outside the monitored space. Push the RDU onto the panel
holder and stick the warning paper next to the RDU.
The communication cable is pre-wired to the SEU.Route this through to the RDU and plug it into the input
port.Communication between the two units is now established.
The CellAirTM has one relay output which is pre-wired to the SEU.The relay can be used to operate an external
alarm system or ventilation system.It will be triggered when the CO2concentration exceeds the first alarm
level.
After completing the installation,remove the rubber cap from the gas entry point,power the unit up and use
the "DIAG" function to verify the connection between the SEU and the RDU.
