Sprint V/V3/V4/V5
I. Operation
Before using the Sprint flue gas analyser on any heating appliance installation,
ensure you are familiar with the working practices defined in the BS7967 which
details how to perform certain tests and safety issues to consider.
Auto zero setting
Allow the Sprint unit to auto zero during switch on in clean air before per-
forming any of the following tests: flue gas analysis and room CO safety test.
Ensure all tubes and probes are connected before switch on and zero outside
in clean air.
Pump
Sprint runs the internal pump during purge at switch on and switch off, and
during and after some tests. A rotating purge icon will appear on the screen
when purging. The speed and therefore the sound emitted by the pump, may
vary depending on the test being conducted. To save on the battery life, Sprint
will turn off the pump when it is not required.
When the pump is running ensure the exit gas exhaust is not blocked and do
not breath in the exhaust gases.
