Замечания:

- все яхтсмены-скоростники частенько рассказывают, что на большой скорости хода яхты опреснитель плохо работает. Это понятно: он засасывает воду с разрывами, входной патрубок наполняется водой с пузырями воздуха, а отстойник не успевает воздух отделить. Ответ тут однозначный - забирать морскую воду для опреснителя надо тоже из танка, а не прямо из-за борта, тогда такой проблемы с работой опреснителя на скорости не будет. А также не будет проблемы в связи с наклоном судна, когда заборное отверстие опреснителя вообще оказывается над водой!
Тут не вижу проблемы! Набрать воды в танк, сосуд, ёмкость - сколько надо опреснить! - и, контролируя визуально погружение входного потрубка в этот резервуар, включить опреснитель. Набрал 10,5 литров воды - ясно сколько опреснишь! 10 л - вот и всё. Не надо мучить аппарат!

- Есть два случая информации, когда опреснитель вышел из строя при попадании масла в систему всасывания морской воды. Эта причина указана во всех Инструкциях - масло выводит из строя мембрану мгновенно! Можно, конечно, теоретически как-то случайно закачать масло с воды в систему, но это вряд ли в реальной жизни, ведь никто не будет запускать опреснитель на стоянке в порту, у берега, где плавают пятна нефти, масла, отходов! Короче, обеспечивайте всеми силами изоляцию штангов всасывания от возможного попадания машинного масла. Не вижу тут проблем!

SYSTEM DESCRIPTION

The Katadyn PowerSurvivor 40E 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 Assembly: 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. An oil-bath gearbox (drive assembly) converts the rotary motion of the electric motor to a powerful, reciprocating, linear motion for driving the pump piston. The pump pressurizes input seawater to approximately 800 psi (pounds per square inch). The high pressure forces product freshwater through a semipermeable membrane located in the membrane housing. All of these main components have been integrated into a single, compact piece of equipment—with low power consumption, quiet operation and a small footprint.

Prefllter Assembly: The prefilter assembly consists of one prefilter housing and a standard 30-micron prefilter element constructed of polyester fibers. Two standard elements are included with each system. In some exceptional circumstances, an optional second prefilter assembly with a 5-micron prefilter element may be needed (see Kits & Accessories]. The prefilter assembly is separate from the pump, which allows it to be installed in a convenient and accessible location.

Valves: Two high-quality plastic 3-way valves are supplied. The prefilter 3-way valve selects between two input sources for the prefilter assembly (and pump):
Clean seawater during normal operation
An alternate intake line for inputting biocide or a cleaning solution

The product 3-way valve allows easy selection between the two required destinations for the product
freshwater:
A freshwater collection tank for normal operation
A convenient drain location for testing and discarding product freshwater,
biocide and cleaners

Note: If you collect and discard the product freshwater at the same location, manually directing the
output from the product freshwater hose may be the most practical approach. In this case, the
product 3-way valve need not be installed.

Hoses and Hardware: Each PowerSurvivor 40E watermaker is shipped with hardware sufficient to perform a normal installation. The 3/8" I.D. reinforced plastic hose is used for seawater intake and reject brine. The smaller, 3/16" I.D. clear plastic hose is for routing product freshwater. There are also hose clamps and mounting bracket hardware for the prefilter assembly.

Customer-Supplied Equipment: Every installation represents a unique challenge! You or your installer will have to provide:
a reliable source of clean seawater for input to the prefilter 3-way valve
plumbing to an appropriate drain location for the reject brine water
a plumbing solution for your freshwater collection tank.

Our Promise: Every Katadyn PowerSufv/vor 40E watermaker includes a three-year factory warranty and a long history of outstanding customer support. Our reputation for providing a quality product—along with service when and where you need it—is unequaled in the industry. Of course, you may never need us—but, if you do, we'll be there.

INSTALLATION

Do it right the first time and reap the rewards


The PowerSurvivor 40E 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. Although the design and operating requirements of the PowerSurvivor 40E allow much latitude for equipment location, there are several cautions and suggestions you should consider before proceeding with an installation.

INSTALLATION DOs

When choosing a location for the watermaker drive/pump/membrane assembly:

- Avoid areas with excessive heat. Ambient temperatures above 105 F (40 C) exceed the ratings for the electric motor, and excessive heat can damage or destroy the membrane.

(Note: Most engine rooms get hotter than 105 F!)

- Choose a dry area. The motor/drive assembly is not waterproof and can corrode.

- Choose an area free of fuel vapors. The electric motor is not vapor-proof and should not be operated if explosive or flammable materials are present!

- Find a location which allows comfortable access for routine inspection and servicing.

In addition, you should:

- Install the prefilter assembly in an easily accessible location! It needs regular (sometimes daily) inspection and maintenance. For ease of routine maintenance, the choice for this location is probably the single most important decision you will make—plan it carefully!

- Provide a shutoff valve or seacock in the seawater intake line.
- Install a coarse strainer in the seawater intake line.

- We recommend using properly-sized ring terminals and a terminal strip near the pump to connect electric power. This allows for easy testing, removal and servicing when required.

INSTALLATION DONTs

- Don't use a thru-hull installed high on your vessel's hull for your source of seawater intake.
This is especially important for sailboats. Even a normal amount of heel when under sail can cause the thru-hull to be out of the water, allowing air into the intake system. A rolling anchorage can do the same.

ў Don't locate the pump assembly above gear or materials that could be damaged if it leaked.
ў Don't locate the pump assembly near to sleeping quarters, bunks, or other areas that are normally "quiet" areas for yourself or crew members.


PLAN AHEAD FOR MANUAL OPERATION

The PowerSurvivor 40E water-maker was never intended to be part of a vessel's "Abandon Ship" equipment. Its capability for manual operation is useful when normal ship's power is unavailable. If you perform a typical installation, it is unlikely that you would have time to remove the watermaker when abandoning ship. Katadyn produces other desalinators that are specifically designed to be part of your survival equipment. Please visit our website for information on the Survivor 35 and Survivor 06 watermakers, both of which are intended for inclusion in survival kits.

Before finalizing your installation plans, consider how you would manually operate your watermaker, should the need arise. You will require a source of seawater input and a place to drain the reject brine, as well as a product freshwater collection container. Typically, the watermaker will have to be moved to a location convenient for manual pumping. There are two common approaches to implementing such an arrangement:

During your installation, leave adequate service loops in the three hoses to allow the watermaker to be moved to a nearby location convenient for manual operation. This arrangement eliminates the need to disconnect any of the hoses.

Prepare a separate set of hoses to be used during manual operation (recommended). This approach allows the watermaker to be moved to any location for manual operation.

More than likely, the plan you choose will be dictated by the location of the space available. In any case, consider how you would manually operate your watermaker before finalizing your installation plans.

INSTALLATION PROCEDURES

Although every installation has custom aspects, the following general instructions should be useful to the typical installer. Refer to Figure A-1 (in the Appendix) for information on parts identification and system connections.

Incorrect Pump Orientations (see Figure 3)

1. Install Pump: After reading the comments on the preceding pages, decide on a location for the main pump/drive assembly. It should be mounted with the long axis of the membrane housing in a horizontal position. The purpose of this requirement is to avoid two problems:

If the pump develops a seawater leak and is located directly above the drive assembly, the drive assembly and/or electric motor may be damaged (Figure 3, left).

If the drive assembly develops an oil leak and is located directly above the pump, oil may find its way into the pumping system and damage the membrane (Figure 3, right).

We recommend securely thru-bolting the pump/drive assembly to a sturdy bulkhead or platform, using corrosion-resistant 1/4" fasteners with flat washers (See Figure A-1). Pick a location that allows ample space for routing the required hoses and electrical wires to the pump and motor.

Неправильные Ориентации Насоса (см. иллюстрацию 3),
mainbrowser-186.jpg

1. Установите Насос: После чтения комментариев к предыдущим страницам, выберите местоположение для опреснителя. Всё должно быть установлено с продольной осью мембранного блока в горизонтальном положении. Цель этого требования, чтобы избежать двух проблем:

Если в насосе есть утечка морской воды, а расположен он непосредственно над двигателем, то или двигатель, или электромотор могут быть повреждены (иллюстрация 3)!

Если у двигателя есть хоть немного утечка масла и расположен он непосредственно над насосом, то масло обязательно найдёт свой путь в насосную систему и тогда повредит мембрану (рисунок 3, справа).

Мы рекомендуем надёжными болтами прикрепить систему к крепкой переборке или платформе, используя стойкие к коррозии 1/4" болты с плоскими шайбами (См. иллюстрацию A-1). Выберите такое местоположение, которое позволяет свободно располагаться всем шлангам и электрическим проводам, идущим к насосу и двигателю.
