NOTE: IF SOLDER TYPE FITTINGS ARE USED DO NOT USE torch near inlet/outlet connections. All solder joints
should be made before joining pipe to filter head.
DO NOT over-tighten metal fittings on to unit connections.
The unit should only be moved by 2 or more people due to heavy weight. Failure to do so can result in back or other
injury.
DO NOT TURN FILTER UPSIDE DOWN
How to check well pump flow rate (must be more than 5 GPM (19 LPM).
Make sure that the pressure tank is full and no one uses any water until you have finished the test.
1) Connect a hose to an appropriate outlet at the bottom of the pressure tank and put the other end into an empty
pail of known volume (e.g. a 10 gal pail)
2) Open the valve to which the hose is connected and collect water into the container. Shut off the valve as soon as
you hear the well pump come on. Measure the volume of water collected. This is the drawdown from the tank.
3) Note the time in seconds that it takes for the pump to complete a cycle from start to shut-off.
Well pump flow rate = (Volume of water collected (drawdown) ÷Time for pump cycle) x 60
EXAMPLE : If you collect 5 gal of water and the pump takes 40 seconds to complete a cycle, the flow rate is:
(5/40) x 60 = 7.5 GPM.
INSTALLATION
Electrical Requirements:
The automatic control valve requires a constant power supply - 120V/60 Hz AC. We recommend a GFI (ground fault
interrupter) outlet within 5 feet of the CAFO Filter. Extension cords are not recommended.
If water pipes are used to ground electrical system, you will need to install a jumper wire across the filter unit.
