Page 5: Congratulations
CONGRATULATIONS Your Spot Zero™ reverse osmosis system is a durable piece of equipment, which, with proper care, will last for many years. This User’s Manual outlines installation, operation, maintenance and troubleshooting details vital to the sustained performance of your system. Your system is designed to operate at a pressure of 80- 150 psi, unless otherwise stated. - Page 6 Pre-Filtration Spot Zero™ systems are supplied with a 1 micron sediment pre-filter (part # 252404005) that filters out most particles over 1 microns, a GAC/KDF (part # 252404004) Cartridge that removes chlorine, chloramine, VOCs and heavy metals. CAUTION: a traditional carbon block filter must not be used as it will not remove chlora- mines and will cause permanent membrane damage.

Page 8: Principles Of Reverse Osmosis
PRINCIPLES OF REVERSE OSMOSIS REVERSE OSMOSIS How Fresh Water Is Produced Reverse Osmosis or “RO” is a process where freshwater water is produced by pumping saltwater through a semi-permeable membrane. Osmosis Osmosis is a naturally occurring process where a weak solution will cross a semi-permeable mem- brane to mix with a highly concentrated solution. -

INSTALLATION PROCEDURE FEED WATER 1. Plumb the feed water from the dock into the pre-filter inlet pressure regulator fitting. 1/2” FNPT or 1” MNPT custom connection from customer. Feed from dock 2. Tube cutting and installation procedure. Push the tube into the fitting, to the tube stop. Cut the tube square and remove burrs and sharp edg- es. - Page 12 3. From the pre- filter outlet fitting, run the white nylon 1/2” Spot Zero water tubing to the feed from pre-filtration fitting. 1/2” Tube From the “Overboard” discharge fitting, run the white nylon 1/2” Spot Zero water tubing to a dedicated overboard fitting.
- Page 13 5. From the product to tank fitting, run the white nylon 3/8” Spot Zero water tubing to the vessels fresh water tank. Ship’s fresh 3/8” Tube water tank FEED FROM WATERMAKER Connect the 3/8” product line from the water maker to the “WATER MAKER IN” fitting. Always install a three way valve in line with this, so the water can be diverted to the spot zero system, or to the vessels fresh water tank.

4. SYSTEM MAINTENANCE... - Page 41 Is my System Working Properly? TDS Rejection The Spot Zero ZTC reverse osmosis system is designed to reject 94% or more total dissolved solids (TDS). The rejection percentage is calculated by the following formula: % Rejection = ((Feed TDS - Product TDS) / Feed TDS) * 100 Example 1 :( (117ppm—4ppm) / 117ppm) * 100 = 96.58% Example 2 : ((900ppm-45ppm) / 900ppm) * 100 = 95% Both example s represent membranes in perfectly operating condition.

Needle nose pliers may be necessary to pull the old membrane element out of the pressure vessel. 6. Remove new membrane element from container and inspect. Make sure that all parts are clean and free from dirt.
- Page 45 10. With a smooth and constant motion, push the membrane element into the housing so that the brine seal enters the housing without coming out of the brine seal groove. A slow twisting motion should be used to insert the membrane element, to ensure that the brine seal stays in place. 11.
