Sprint Pro Maintenance and Calibration
The water trap must be dried before use and before
returning to the carry case after use.
If the filter becomes blocked clean it or replace it.
Note: Where a CO
2
sensor is fitted as carbon dioxide is
slightly soluble, a lot of water present in the water trap may
lead to inaccurate Room Safety test readings. There are no such concerns with flue
gas measurements as Sprint Pro measures oxygen, which is insoluble, and calculates
carbon dioxide in flue gas instead of measuring carbon dioxide directly. This means the
solubility of carbon dioxide does not lead to errors in flue gas measurements.
Replacing/Cleaning the dust filter:
The dust filter element should be changed if the filter has become contami-
nated, dirty or if the Sprint Pro pump stalls indicating a blockage. If the filter
has become soaked with water, remove from trap and squeeze the water out
before reusing or replacing.
Replacing/Cleaning the water filter
The water filter element should be changed if the filter has become contami-
nated, dirty or if the Sprint Pro pump stalls indicating a blockage. If the filter has
become soaked with water, remove from trap and blow the water. If the filter
has become saturated it may be necessary to fully dry before reuse. If the filter
is very contaminated it may be necessary to replace the filter.
After cleaning moisture out or after any filter changes, make sure the O-ring
and middle disc are re-fitted in the correct position (as shown above) and the
locating lugs are carefully aligned before twisting to close the water trap. Check
the fastening ring of the water trap has been closed such that air cannot leak
in to the water trap.
Warning:
Water trap and filters
must be used at all
times.
