REMOVING AND ADDING A SENSOR

If you are adding or removing a sensor, be aware of the
following:
Adding a sensor. This involves increasing the number of
sensors in the instrument. For example, to add a fourth
sensor to a three-gas unit, remove the plug, which is
located on the gas plate above the new sensor, so that gas
is allowed to reach the new sensor.
Removing a sensor. This involves reducing the number of
sensors in the instrument. In this event, it is necessary to
insert a plug (Part number XIF936) in the gas plate to
prevent gas leakage where the vacated sensor no longer
resides.

CLEANING

PUMP INLET FILTER REPLACEMENT

If the inlet filter is clogged, the flow rate of the pump is
decreased, and in severe cases, the instrument will go into
low flow alarm, or the pump can be heard to be struggling
under the increased load caused by the restriction.
To replace the filter, use tweezers to pull out the tubing and
filter. Install a new filter (Part number XIP604) and secure
