CARTRIDGE REPLACEMENT
The Sensor Cartridges have a two year lifespan from their date of manufacture. After the
expiration date their readings may be unreliable. A warning will pop-up on the GX4
the cartridge is going to expire in 30 days and will reset every day until it expires. Once the
cartridge expires a message will pop every 6 hours and the AUX will not output the OK signal.
Upon removal of a cartridge, a warning message will appear on the screen. If a response to
this warning is not made within 30 seconds, the alarm will sound. This is a safety feature to
detect a cartridge coming out of the unit unintentionally.
MAINTENANCE SCHEDULE:
Weekly: Check the manifold tube, sintered bronze inlet filter
Monthly: Sensor Cartridges - clean contacts, calibration check
Every 3 months: Check for firmware updates (and when a new cartridge is installed)
