Installation Instructions (cont.) STEP 10: Use polyethylene drain line tubing provided (NO VINYL TUBING) to run drain line from control valve discharge fitting to floor drain or sump pit capable of handling the backwash rate of the filter (refer to specifications and flow rate on page 12). DISCHARGE END OF THE DRAIN LINE MUST BE FIRMLY SECURED! There must be an air gap at the end of the drain line to prevent siphoning of waste water and meet plumbing code.

Power outages will cause the units time clock to be inaccurate and backwashing will not occur at the planned time. 2) If your unit contains activated carbon, you must replace the carbon and gravel underbed at least every three years.
