Thank you… for purchasing a Katadyn PowerSurvivor 80E watermaker. It was built to rigorous specifications, and designed to produce potable freshwater from clean seawater using minimal power. It is simple to install and operate and, with reasonable care and maintenance, will provide years of useful service. Please… before installing or operating your watermaker, take the short time needed to read this User’s Manual in its entirety.

System Description The Katadyn PowerSurvivor 80E watermaker system has several components. Refer to the System Diagram (Figure A-1) in the Appendix for an overview of the components of the system and their interconnections. Motor/Drive/Pump & Membrane Housing: At the heart of the watermaker system is a high-pressure, positive-displacement pump. The pump is powered by a reliable 12 (or 24) VDC electric motor.

Energy Recovery The technology behind Katadyn reverse osmosis watermakers Reverse osmosis desalination was first developed over three decades ago. It was a major breakthrough in desalting technology, but the original process required a lot of power. By recovering 90% of the energy lost in conventional reverse osmosis systems, we’ve made small desalinators practical, so you can have freshwater when and where you need it.
Installation Do it right the first time and reap the rewards The PowerSurvivor 80E watermaker utilizes a low-volume, high-pressure, positive displacement pump. Unlike the centrifugal pumps found in some systems, a positive displacement pump is self-priming. It can also draw water when mounted several feet above the waterline of a vessel. Thus, the watermaker may be installed in almost any location and orientation. The most important part of a good installation is proper planning.
Installation Procedures Although every installation has its custom aspects, the following general instructions should be useful to the typical installer. Refer to Figure A-1 (in the Appendix) for information on part identification and system connections. 1. Install Pump: After reading the comments on the preceding pages, decide on a location for the pump and drive assembly. It should be mounted with the pump and drive side by side horizontally.
4. Install Seawater Intake Plumbing: There are two common approaches to providing the seawater intake circuit: • Tee into an existing seawater intake (e.g., engine cooling water or manual seawater pump inlet). • Install a dedicated thru-hull for the watermaker. Either of these configurations should meet the following criteria: • It should be at a low point on the vessel’s hull, to minimize the chance of air intake during heeling or rough conditions. • The thru-hull should be a minimum of 1/2" I.D.
The preferred method for collecting product freshwater is to use portable jerry jugs or a separate “day tank,” which is isolated from the main storage tank. Some method should be devised for testing the product freshwater quality at the beginning and at the end of each operation. When you are certain that the quality of the collected product freshwater is acceptable, it can be transferred to the main storage tank.
• petroleum products, such as oil, fuel, thinners, paints, paint removers, etc. • chlorine-treated water (for example, most “dockside” water) • silty water—water contaminated by fine, hard, suspended particulates • putrid water, “red tides”, or any seawater that smells or looks contaminated It is important to remember that the watermaker is designed to process clean, open-ocean seawater.
Note: Organic growth is much more rapid in warm or tropical climates. If using the watermaker in a tropical environment, we recommend a membrane preservative treatment if the watermaker will not be run again within the next three days! Before doing repairs or maintenance work on a PowerSurvivor, close the seawater inlet valve after turning off the system. Otherwise, the possibility exists that hose failure, for example, could cause the boat to sink.
Maintenance and Service A little love goes a long way We’ve worked hard to design a product that is simple to operate and maintain. However, regular attention to the few maintenance requirements of this equipment is critically important. This section of the Owner’s Manual describes both the routine and the long-term maintenance requirements of the PowerSurvivor 80E.
Prefilter Maintenance Background: Maintaining a healthy watermaker largely involves taking proper care of the prefilter assembly and seawater intake plumbing. Failure to do so is the most common cause of the two most frequent types of watermaker “failure” we hear about: (1) producing diminished or no freshwater output, or (2) producing “bad-smelling” product freshwater.
1. Unscrew the prefilter housing, remove the dirty Warning: If you purchase afterprefilter element, and discard the water in the market filter elements, be certain bowl. Do not lose the large o-ring at the top of they are made from polyester fibers. the bowl. In particular, be wary of elements 2.

In temperate climates, the maximum period of time the watermaker should be stored without preserving the membrane is approximately one week. In hot or tropical climates, the watermaker membrane should be preserved if it will not be used within the next three days. Follow these directions to preserve the membrane of your watermaker: 1. Turn the Clean/Run Valve lever on the pump to its “Clean” position (see Figure 8). 2.
The only indication that the membranes might benefit from cleaning is a substantial reduction in the quantity of product freshwater output, all other factors being normal (e.g., battery voltage, salinity, seawater temperature). The best way to detect such a problem is by keeping an accurate log of product freshwater output at known battery voltages. Such a practice is highly recommended.
Seal Replacement After approximately every 1000 hours of use, the watermaker should be partially disassembled, cleaned, and lubricated with non-petroleum silicon grease. At that time, the seals should be inspected and replaced, as required. The standard Repair Seal Kit (included in the Extended Cruising Kit—see Kits and Accessories) is available from Katadyn and most marine retail stores. It includes a complete set of replacement seals and other components for all user-serviceable parts of the watermaker.
Disassembly: 1. Before beginning disassembly, run the watermaker and stop it when the piston shaft is at its farthest point of travel away from the pump (toward the drive assembly). This provides enough room for sliding the rubber boot back toward the pump in Step 3. 2. Use the 11/16" open-end wrench to disconnect the two high-pressure hoses (coming from the membrane housing) from the tube connectors on the check valve plate and the valve assembly.
5. Disassemble the two check valve assemblies. Use the needle nose pliers to lift the intake valve retainer, valve spring and poppet valve out of their bore in the inside surface of the check valve plate. Remove the tube fitting, reject check valve retainer, valve spring and poppet valve from their bore in the outside surface of the check valve plate.
Reassembly: Before you begin reassembly of the watermaker, clean all parts using clean, lint-free rags. At this time, all parts should be carefully inspected for wear or damage. Use a 10x magnifier or loupe to examine the seals, o-rings and other small parts. Stubborn rust stains and deposits on metal parts may be cleaned with a soft-metal wire brush (e.g., stainless steel or brass). Do not use polishes, cleaning compounds containing abrasive materials, or regular steel wire brushes.
3. With its cross side facing down (facing the valve seat), lower a new poppet valve into the bore for the reject check valve. The poppet valve should be level and in the center of the valve seat at the bottom of the bore. Observe that one end of the valve retainers has a shallow hole that is the same diameter as the valve spring. Press a new spring into the hole in one of the retainers. When installed correctly, the spring should stay in the valve retainer when it is inverted.
7. Refer to Figure R-8. Slide one backup washer over the piston shaft and down into the shaft bore in the pump back plate. Slide one of the shaft seals over the end of the piston shaft with its flared side (the side with an embedded o-ring) facing the pump back plate. Slide it down the shaft and gently work it into the shaft bore. In-stall the second shaft seal in exactly the same way, with its flared side also facing the pump back plate.
