6. Troubleshooting guide
In the unlikely event that a problem occurs on the equipment, this troubleshooting guide can be used to identify the probable cause
and remedy.
Troubleshooting should only be attempted by competent personnel. All major repair, and calibration work should be
undertaken by a domnick hunter trained, qualified and approved engineer.
Warning
Problem
Poor dewpoint identified by water in
the downstream piping and equipment.
High pressure drop resulting in low
pressure gauge readings or
intermittent operation of the
downstream equipment.
Interruption of the air supply
downstream leading to a rapid loss
of system pressure.
Possible cause
Dryer is operating outside of its
sizing criteria.
Bypass valve is open.
Dryer has recently been started.
The condensate is not being
drained.
Regeneration column pressure >
350mbar.
Timer malfunction.
Valve malfunction.
Desiccant is approaching the end
of its useful life.
The pre / after filtration is approaching the
end of its operational life.
The dryer is being overflowed or is
operating at a reduced system
pressure.
An isolation valve is partially
closed.
Pressure loss from the system.
Compressor switched off.

Check the condensate drain(s) for
faults.
Check the drain hoses are free from
kinks and obstructions.
