FIT System Configuration Instructions
FIT Systems do not require the user to assemble any plumbing. The unit has been designed for complete turnkey ease.
The air pump needs to be placed on location, and air lines ran to the air inlet points on the filter. An air check valve should be installed to keep water reaching the air pump or the air pump can be located above the water level on a high shelf so that water cannot reach it. If water gets to the air pump, it can burn out the pump or cause a dangerous electrical situation.
Once the air has been hooked up, fill the tank with water and make sure the water is circulating between the filter and the tank. The tank inlet pipe should have a continuous stream of water and not gurgle. The ideal water level is at half the height of the tank inlet pipe.
