3.1.3 Signal status display The status display uses colors and/or flashing patterns to display the oper- ating status of the 948 Continuous IC Module. The meaning of the colors and flashing patterns is explained in the following table. Visual signal Meaning LED lights up orange.
In the eluent chamber, potassium (K ) and hydroxide ions (OH ) combine to form potassium hydroxide (K ). The eluent thus consists of potas- sium hydroxide (K ), water (H O), hydrogen (H ■■■■■■■■ 948 Continuous IC Module (2.948.00x0)

A stopper closes the Exhaust opening of the Eluent Producer cartridge. Concentrate may leak out if the exhaust opening is open while the bottle is being handled. Make sure that the 948 Continuous IC Module is switched off to ■ change the concentrate bottle.
High-pressure degasser – Function *) The optional port can be used, for example, to remove condensate from the outer tubing or for active external rinsing. Metrohm recommends a passive setup for applications with an MSM (see chapter 4.5.1, page 33).
Do not remove or loosen the degasser tubing at the rear of the high- pressure degasser. Doing so would mean that the perfect functioning of the high-pressure degasser is no longer ensured.

However, unplug the power plug immediately if you suspect that corrosive media have gotten inside the instrument. This is the only way to prevent extreme damage to the instrument electronics. Contact Metrohm Service immediately. 948 Continuous IC Module (2.948.00x0)
Maintenance by Metrohm Service Maintenance of the instrument is best carried out as part of annual service, which is performed by specialist personnel from Metrohm. A shorter maintenance interval is recommended if you frequently work with caustic and corrosive chemicals. Regional Metrohm service representatives offer every form of technical advice for maintenance and service of all Metrohm devices.
