Attaching an Expansion Tier to the NGC Instrument
WARNING! Disconnect power to the NGC instrument before attaching an
expansion tier. Do not attempt to service any component on the NGC
instrument unless noted in this manual. Contact Bio-Rad for service requests.
To attach the connector cable, you will need access to the back of the NGC
instrument. If necessary, pull the NGC instrument away from the wall and rotate the
instrument to gain access.
Important: If you are adding a fourth expansion tier, you must attach it to an
already attached third tier. The third and fourth tiers are not interchangeable.
Ensure that the third tier is installed on the NGC instrument before attaching the
fourth tier.
To attach an expansion tier to the NGC instrument
1. On the touch screen, select Shut Down on the dropdown menu to exit
ChromLab and shut down the NGC instrument.
2. Remove all tubing lines to sample and buffer bottles and remove any bottles
from the buffer tray.
3. Lift the top off the NGC instrument and place it on the lab bench.
