TROUBLESHOOTING
PROBLEM POSSIBLE CAUSES POSSIBLE CORRECTIVE STEPS
Great amount of water is dropping
from the nozzles onto the ground.
Too much water to the
nozzles.
Reduce amount of water delivered to the nozzles. Refer to
the Operation Principle/Sequence of Operation section of the
adiabatic controller programming manual to understand your
conguration and adjust the amount of water by following
instructions on page 17 to page 19.
The amount of water should be enough to make the FT or
pressure decrease but without having too much un-atomized
water fall to the ground.
Some nozzles not spraying when
pulsing valve is open. Other nozzles
are spraying properly.
Defective nozzles. Clean or replace faulty nozzles.
Water lter cartridge alarm triggered.
Water particle lter is
clogged.
Replace cartridge and reset alarm.
Pump is making cavitation sound
(The pump will either produce
a “whining” sound (more mild
conditions) or a “rattling” sound (from
intense implosions) that can sound
like marbles in a can)
Not enough water pressure
at pump inlet.
1. Check for proper water ow. Water inlet to the pump
should be at least 40 PSI (when using city water).
2. Check water lter; may be clogged. Replace if needed.
3. Make sure water inlet pipe dimension is respected
according to the information supplied previously in this
manual.
4. Check for obstruction. Verify if obstructed water lter alarm
is triggered. If so, replace lter and reset alarm.
Water hammer effect on the system
(a loud “thunk” sound and piping
sudden vibration)
Water pressure not
adjusted properly, may be
too high.
Adjust water pressure following instructions on page 7 of
this manual.
The controller does not seem to
control the system.
Ex.: System should spray water but
is not, or vice versa.
Not proper voltage/wiring
1. Check voltage on output of transformers CT1. It should be
between 20.4V and 26.4V AC. 24V is recommended.
2. Check system power input and compare to wiring diagram.
Display shows pump is ON but pump
is not running or too hot.
Input voltage is too low or
too high for the pump.
Pump thermal protection
may be triggered.
Check system input voltage and compare to wiring diagram.
