Flow Detector Calibration
To calibrate the flow detector go into the maintenance screen and put the system into maintenance mode.
Then turn the pump on and open panel door. Adjust the flow regulator so that the float is between 1.5-
2LPM.
On the Flow detector card is a small yellow button. Press and hold that button for one second until the
indicator light begins to blink green. This indicates that the card is ready to accept its low flow calibration
set point. With the flow regulator adjusted to approximately 1.5-2 LPM press and hold the yellow button
until the light stops blinking green then release it.
The indicator light will begin blinking red indicating that it is ready for the high flow set point. Adjust the
flow regulator to allow for full flow which should be approximately 4 LPM. Wait a few seconds to allow the
flow detector to stabilize then press and hold the yellow button again until the light stops blinking red and
then release it.
The indicator light should be solid green which indicates that the flow is within the calibrated parameters. If
the light is blinking green and red the calibration was not accepted. Repeat the process using a slightly
higher or lower low flow set point.
Once a successful calibration has been accepted lower the flow slowly to make sure the indicator light turns
red at approximately 1-1 .5 LPM and that you hear the relay energize and “click”. If the calibration worked
correctly raise the flow to approximately 3 LPM and close the door and put the panel back into run mode.
If the light does not turn red within .5 LPM of the low flow set point a calibration will have to be attempted
again. On the second attempt during the full flow calibration slightly restrict the exhaust port with a finger
to allow slightly more pressure to build in the system. Verify that the flow detector indicator light turns red
at approximately 1-1.5 LPM

Replacement Parts
Damaged or questionable parts should be replaced immediately upon
detection. Damaged or inoperative parts could contribute to hazardous and/or unsafe conditions. Any
consumable parts should be replaced if the reliability is questionable or within the part’s specific
expected life. Consumable parts include any filters, pumps, sensors, solenoids….etc.
