Filter:
If the sample gas flow rate is reduced too much due to an old clogged
filter then the flow warning (flashing pump icon) will be displayed.
Filters should only be replaced with the correct type. The in-line
filter MUST ALWAYS be used, or your PurgEye
®
may read incorrectly
and/ or be permanently damaged.
Spare filters available from your HFT
®
Distributor.
Internal Pump
:
The internal pump should not be force fed with any pressure as it
may be damaged. Keep the pressure of the purge gas at 0.5 bar
(7.5 psi) or lower at all times.
Calibration:
HFT
®
has a number of calibration facilities internationally. Contact
your nearest HFT
®
Distributor who can tell you about your closest
one.
Testing gas source:
As well as its use as a Weld Purge Monitor
®
the PurgEye
®
Site can
be used to test the quality of your purge gas supply.
Ensure that a regulator is connected to the gas supply and that it
is set to 0.5 bar. Set the flow rate to 3 litres/min and connect the
PurgEye
®
monitor to the gas flow using a suitable tube.
Quick Fit tube connections:
These fittings are leak tight and pressure tight. They are designed
to take 6mm OD Polyurethane tube.
