Troubleshooting:
Problem
Solution
The unit fails to operate
Verify that the unit is plugged in and that electrical power is available.
The unit fails to produce mist.
Verify that the source water hose is connected and that inlet valve and the hose bib
are both open and that water flow is adequate.
The source water pressure should be between 20 and 125 Psig. The flow capacity at
the unit should be at least 1/2 gallon per minute.
One or more nozzles fail to produce mist while
others do.
The nozzles not producing mist may be plugged and should be cleaned or replaced.
The external Water Conditioner cartridge or the internal filter element needs to be
replaced.
The fan runs poorly, or extremely hot.
Check the electrical power available at the unit.
120 Volt units will operate correctly with electrical voltage readings from
108 Volts to 132 Volts AC
.
Class “B” motors are designed to operate at a “motor winding temperature” that does
not exceed 266
o
F. The fan motor is protected by an automatic reset thermal overload
device.
The fan operates intermittently without human
intervention.
The thermal overload device protecting the fan motor is doing its job, (protecting the
motor from overheating).
The misting pump does not run or runs
intermittently.
Check the electrical power available at the unit. (See above)
Check the water source valves. If any have been closed, the pump will stop
automatically and the safety pressure switch will be “ON.”
It is normal for the pump motor to “feel hot.” If the pump motor is not running
verify that the safety pressure switch light is “OFF.”
This will be likely to happen to a pump motor if the discharge pressure has been set
too high. Set the pressure regulator to 700 Psig maximum. In any event, do not
exceed the FLA (Full Load Amps) listed on the motor nameplate. Use an ammeter to
verify the setting.
The pump motor will run intermittently when either or both the filter and water
conditioner must be replaced. When the filter or water conditioner become plugged
due to sediment accumulation, the pressure switch will stop the pump motor. When
the pressure builds up again, the pump will run for a short period of time. Replace
the water conditioner and the filter cartridge.
If this becomes a common occurrence, the motor may have developed a problem
requiring replacement.
The unit leaks water from the misting pump
compartment.
Disconnect the unit electrical power. Remove the pump compartment cover and
inspect for leaks.
The drain valve will release a small volume of water each time the pump is stopped.
This is for the purpose of draining water from the misting nozzle ring.
A thermal relief valve will discharge water when the water temperature exceeds 140
o
F. This protects the pump from heat damage and is normal.
Repair any other leaks as needed.
