Installation Requirements
AIR GAP REQUIREMENTS
A drain is needed for Clean Rinse discharge water. A floor drain, close to the Central Water Filtration System, is preferred. A laundry tub, standpipe, etc. are other drain options. Secure valve drain hose in place. Leave an air gap of
The Commonwealth of Massachusetts plumbing code
VALVE DRAIN REQUIREMENTS
Using the flexible drain hose (included), measure and cut to the length needed. Flexible drain hose is not allowed in all localities (check your plumbing codes). If local codes do not allow use of a flexible drain hose, a rigid valve drain run must be used. Purchase a com- pression fitting (1/4 NPT x 1/2 in. minimum tube) and 1/2" tubing from your local hardware store. Plumb a rigid drain as needed (see Figure 4, below).
NOTE: Avoid drain hose runs longer that 30 feet. Make the valve drain line as short and direct as possible.
It is recommended that the Central Water Filtration System be installed near a drain. However, if a drain is not available, it is still possible to operate the Central Water Filtration System in.a manual Clean Rinse mode. See “Operating in Manual Clean Rinse Mode” section. The automatic Clean Rinse function must be disabled if the Central Water Filtration System will not be connected to a drain.
