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.
The dryer tripped due to power
supply interruption to the dryer.
The compressor tripped due to power
supply interruption to the compressor.
Isolation valve closed
Compressor switched off.
Fault shutdown event.

pressure relief valves are closed.
Check that the dryer "POWER ON"
indicator is illuminated. If it is not
