2.9. System Check
1. Run the system through a couple of cycles to ensure all components are working properly.
2. The blower timer is preset for 5 minutes delay. After the solenoid valves shut, check that the blower
continues running for the preset number of minutes delay.
3. Open the tank and check the system.
a. Remove the tank lid.
b. Lower the water level in the tank by opening a bath tub tap, or similar, within the residence.
The floats will fall with the water level. The minimum water level is reached when the lower
float drops (except on 433-S50 & 433-S50X systems where minimum water level occurs when
the middle float drops). There will be an audible click and the solenoid will open allowing the
tank to start filling; the blower should also start running. The water level must rise regardless
of how many taps are open within the residence.
c. While the tank is filling, lift the lower float (middle float on 433-S50 & 433-S50X), water in
flow should stop and the blower will remain running (until the end of the preset delay).
Release the lower float.
d.While the tank is still filling lift the upper float; water in flow should stop and the blower
will remain running. Release the upper float. Pushing down the lower float on 433-S50
and 433-S50X Systems will shut off the pump.
e. Remember to shut off any open taps within the residence.
4. Replace the lid and secure with the fasteners provided. With the System running check the lid for
air leaks between lid gasket and tank. If leaks occur the fasteners should be tightened until leaks are
eliminated.
5. Make sure you have properly labeled the system with the necessary installer information (i.e. company
name, phone number, date installed, etc.) and you have left all system information with the home owner.
6. The AIRaider System is now operational.
