Start Up ü Ensure power switch (located on top of control Box). 2 3 (#1) is in the OFF position. 4 ü Plug the unit into an appropriate power supply. ü If installing a pressure Tank system, open the Ball 6 Valve (#2) on the Bulkhead. 7 ü Turn the Blending Valve to coldest setting [90°]. (#3) ü Fully open the Concentrate Needle (#4) Valve by turning it counter clockwise. ü Fully close Recirculate Needle Valve (#5) by turning it clockwise.
ALARMS M-Series processors are equipped with audible alarms. 1. The Constant Tone signals lack of incoming water pressure. (-------------------------------------------------------- Constant Tone) • Check incoming feed pressure to ensure a minimum of 20 psi. • Water pressure below 20 psi will trigger alarm. Incoming feed water pressure must be raised. 2. One second intermittent beeping signals systems is in Auto –Bypass. (-- -- -- -- -- -- -- -- -- -- -- -- -- -- One second intermittent tone).
Maintenance Quarterly Preventive Maintenance for Systems with complete Pre and Post treatment. The M-Series RO processor requires quarterly preventive maintenance consisting of replacing (3) pre-filters and post Filters if supplied. 1. Pre-filters are located on left side of RO processor. 2. Post filters located on right side of RO processor unit. Quarterly preventive maintenance procedure. 1. Turn incoming feed water off while unit is running. 2.
Annual Preventive Maintenance Perform quarterly preventive maintenance. Include replacement of O-Rings. Replace RO membrane by loosen retaining clamp at top of stainless steel membrane vessel . Carefully pry loose PVC end cap from stainless steel vessel. Pull membrane from vessel using pliers i necessary and discard. Take note of location of black BRINE SEAL located approx. 1/2” from one end of membrane, so the new membrane will be installed in the proper direction.
Annual Preventive Maintenance Lubricate O-Rings on both ends of the Membrane and PVC Vessel Cap with K-Y Jelly or other water soluble lubricant. *Vaseline or other petroleum based lubricants will damage rubber o-ring and cause leaks. Insert new membrane into vessel with the Brine Seal on same position as the old one just removed. Replace PVC end cap and tighten clamp evenly.

GLOSSARY OF TERMS Atmospheric tank: A storage container requiring additional delivery system to distribute stored water. Typically constructed of polyurethane or stainless steel. Used in situations where greater storage capacity is needed than offered by conventional pressure tanks. Auto By-Pass: A feature that allows tap water to be delivered to downstream demands in the event the RO processor is unable to meet demand.
GLOSSARY OF TERMS (Continued) Permeate: That portion of the feed water which passes through the membrane to become product water. Permeate Line: Tubing or pipe used to transport purified (RO processed) water from processor to the storage tank. Pressure tank: A water storage device using a pressurized bladder that provides delivery pressure to down stream uses. Purge: The act of flushing out.
