Page 5: Congratulations
Congratulations Your S SZIII-Series ultra-purification system is a durable piece of equipment that, with proper care, will last for many years. This user manual outlines installation, operation, maintenance, and troubleshooting details vital to the sustained performance of your system. If your system is altered at the site of operation or if the feed water conditions change, please contact your local dealer or distributor to determine the proper recovery for your application. -
Page 6: Principles Of Reverse Osmosis
Principles of Reverse Osmosis How Fresh Water is Produced Reverse Osmosis or is a process used to remove large volume of contaminants from water by forcing the fluid through a semi-permeable membrane. Osmosis Osmosis is a naturally occurring process where a weak solution will cross a semipermeable membrane to mix with a highly concentrated solution. -

Page 14: Pre-Filtration
PRE-FILTRATION The SZIII is supplied with a 10 sediment pre-filter (Part #: 252404005) that filters out most contaminants over 1 micron, and a GAC/KDF prefilter that removes chlorine, chloramine, VOCs and heavy metals (Part #: 252404004). An additional commercial- grade filter configuration is optional with a single 20 commercial prefilter (Part #: 252404301). -
Page 15: Overboard Connection
Overboard Connection ship overboard line. For most single unit applications, QC tube may be acceptable, and should be plumbed into the dedicated overboard connection on the unit. SPOT ZERO SYSTEMS REQUIRE THAT THE OVERBOARD MUST NEVER BE CLOSED OR OBSTRUCTED WHILE SYSTEM IS OPERATIONAL. CLOSING OR WARNING OBSTRUCTING THE OVERBOARD FLOW ON THE SYSTEM MAY CAUSE PERMANENT DAMAGE TO THE SYSTEM. -

Page 19: Operation Specifications
Operation Specifications It is imperative that the operation specifications laid out in this document are followed precisely. The reverse osmosis process results in the concentration of filtered impurities and neglecting to follow the operating procedures may cause the impurities to solidify and scale or foul the membranes. To prevent this, your SZIII system should never be operated over the rated production or above the max pump pressure of 150psi. -
Page 21: Temperature Correction Factors For Membrane Production
Temperature Correction Factors for Membrane Production The reverse osmosis process is also heavily dependent on the input water temperature. This is because higher temperature water has a reduced viscosity which makes it easier for the water to permeate the RO membrane. Because of this, at different temperatures the unit will either produce more or less product than its rated production at 77°F. -
Page 22: Rejection, Recovery, And Flow Rates
Rejection, Recovery, and Flow Rates The Spot Zero SZIII system is designed to produce product water at the capacities indicated by the model number. For example, the SZIII-2000 produces 2000 gallons per day (1.39 gallons per minute) of permeate water at the listed operating test conditions. Meanwhile the SZIII-3000 produces 3000 gallons per day (2.08 gallons per minute) at the same test condition. -
Page 23: Components Of The Sziii Unit
Components of the SZIII Unit System Controller The controller is a logic-based PC board that can analyze and control all electrical components within the system. Its primary functions are to monitor safety thresholds of high and low pressure and perform the proper sequence of operations to optimize the start, running, and shut-down operations. Freshwater RO Pump The pump used on the SZIII-series systems is a rotary vane pump constructed out of bronze. -
Page 24: Membrane Replacement And Removal
Membrane Replacement and Removal Replacing membranes in the pressure vessels is an easy process if you have the proper information and tools at hand. Please refer to the following instructions when removing and replacing membrane elements: ALL PRESSURE GAUGES MUST READ ZERO BEFORE PROCEDING. DISCONNECT WARNING THE POWER AND BLEED ALL WATER PRESSURE FROM THE SYSTEM. -
Page 25: Inserting The New Membrane
5. Slowly remove the membrane from the pressure vessel being careful not to grasp it by the permeate tube. Needle nose pliers may be necessary to pull out the old membrane element. This may take a bit of force to do as the membrane may have come tightly pressed to the walls of the vessel. - Page 26 THE BRINE SEAL MUST BE IN THE SAME POSITION FOR EACH MEMBRANE ELEMENT HOUSING. THE BRINE SEAL IS A RUBBER SEAL THAT PROTRUDES ON WARNING ONE SIDE OF THE MEMBRANE AND IS ALWAYS ON THE FEED SIDE OF THE MEMBRANE ELEMENT. Close up of Membrane Insertion Showing Seal Direction 6.

Page 27: Preparing Unit For Storage Or Shipment
Preparing Unit for Storage or Shipment PRIOR TO SHIPPING, THE SYSTEM SHOULD BE CLEANED WITH AN APPROPIATE CLEANER, FLUSHED WITH WATER, AND PROTECTED FROM BIOLOGICAL ATTACK WITH AN APPROPIATE SOLUTION FOR MEMBRANE WARNING ELEMENTS. THE MEMBRANE HOUSING(S) AND PLUMBING LINES OF THE SYSTEM MUST BE COMPLETELY DRAINED. -
Page 28: Recommissioning The System After Storage
Recommissioning the System After Storage 1. To recommission the system after the storage period, connect the tube from the filters back to the bulkhead on the unit. Reconnect the overboard connection back to the unit as well. 2. Fully open the by turning the handle counterclockwise. -
Page 29: Winterization For Your Unit
Winterization For Your Unit There are two options for winterizing your unit. Option 1: Winterization with membrane rack removal The best practice for winterization is to remove the membrane rack and store with Spot Zero membrane storage chemical in a heated storage climate. Information on how to store the system with System fo eed from Desalinator should be disconnected and the remainder of the system should be stored with propylene glycol from the dock water feed inlet to the overboard to prevent freeze damage (propylene... -
Page 30: Recommissioning The System After Winterization

Page 41: Performing A Freshwater Flush
Performing a Freshwater Flush Periodically the unit should be flushed with pure freshwater. This procedure helps to clean the membrane(s) of contaminants and may result in increased membrane longevity and provide better quality water over time. Skipping the freshwater flush can lead to membrane scaling and fouling at or even before the rated lifespan of 100,000 gallons for the membrane(s). -

Page 44: Is My System Working Properly
IS MY SYSTEM WORKING PROPERLY? TDS REJECTION The Spot Zero SZIII reverse osmosis system is designed to reject up to 9 % of 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 examples represent membranes in perfect operating condition. - Page 45 1. A cartridge of Spot Zero chemical cleaner (SZCCC) will need to be purchased it is part number 252404006. 2. Turn the System off. 3. Disconnect Product to Tank and discard any product made during the cleaning process. 4. Remove the filter from the second prefilter housing. (That is remove the prefilter from the filter unit that is on the outlet side of the prefilters.) 5.
