NO FRILLS 500/800 Guide
System-bases
Introduction into the reversion - osmosis
Reverse-osmosis is a process, with which a membrane divides one water-flow in two water
flows. One part is fresh-water and amounts about 7-10 percent of the entire water-quantity,
the other flow is concentrated saltwater, which is washed away. Since saltwater is a solution
of H²O and different solved materials (salt), the membrane acts like a filter. In order to be
able to remove these solved materials from the water, the pores of the membrane must be
smaller than the solved materials that should be taken away. The pores of a membrane are
so small that they can be seen only by one electron microscope. (0,0001 micron), that
means, that the sea-water must be pressed through the membrane. This pressure must have
the strength of 800 Psi (56 bar) approximately. How high the current pressure must be exact,
is a result from the water-temperature and the salt content of the water.
This temperature / pressure-relationship later will be explained later in this handbook.
See chapters: Temperature - Pressure - Correction.
As you know, each filter can become blocked or damaged. A reverse-osmosis-membrane is
no exception. Your System is designed that surplus particles are rinsed with the Brine flow.
Nevertheless, there are conditions, which contaminates, blocked or damage the membrane.
With regular maintenance, as it is described in this handbook, the possibility of a failure of a
membrane can be minimized and costly substitute be avoided. Regular maintenance is
comparatively affordable, gets the effectiveness and extends the lifespan of the installations.

Electric wiring
The connection should be carried out by a qualified electrician.
Control box inside:
Motor connection for CAT Pumps
See attached CD. For Identification of the wires at the pump, we left a short piece of wire out
of the box at the motor. However, you are free to connect the wires inside the box. The build
in switch is not needed. If you leave the switch, make sure, it is in the ON position. The
connection schematic is inside the cup of the box.
Electrical connections should be done by a qualified electrician.

Before mounting!!
Please pay attention to the following points before you fit in your NO FRILLS installation and
take in operation!
1. The installation should be taken in operation within 12 months after delivery
2. The installation should about every 7 days, in very hot areas, every 3 days, operated
with sea water or flushed with fresh-water.
3. If the installation is for a long time out of order, it should at the latest after 12 months
flushed and preserved again.
4. Never operate the system in harbors or in areas where fuel and oil is in the sea-water.
5. If you use the system in fresh - or brackish water, the operating-pressure must be
adjusted, that the output of fresh water is within the operating limits.
6. Protect the installation from freezing.
7. Don't let the membrane dry out. If you take out the membrane for any reason, it has to
be sealed immediately.
8. The sea-water- inlet must be shaped so that the sea-water is pressed in during cruise.
Attention!!
The quantity of the produced drinking water is very strong dependent on the temperature of
the sea-water. All accomplishment-statements are based on a temperature of the sea-water
of 25°C. Per 1°C below 25°C, the production loses 3 percent of performance.
As well, the salinity of the sea water is a factor. Higher salinity, lower performance.

The general scopes of the NO FRILLS desalination-installations
The NO FRILLS RO systems are laid out according to the last realizations of the revers-
osmosis-technology. These installations enjoy ever more severe popularity with Cruisers,
sport-fishers and on boats, where mounting space is limited.
The NO FRILLS systems are simple to use and uncomplicated in maintenance.
The NF 500 produces about. 78 liters / h, the NF 800 produces, about. 145 liters / h. See the
reduced performance with temperatures below 25°C.
2.2 descriptions of the individual parts
The 230 V boost-pump. (LP Pump)
The boost-pump is required to feed the sea-water, if the high-pressure-pump is built-in at or
above the waterline. The booster-pump must be installed below the waterline. The booster-
pump supports the start-process, trapped air is fast removed.
Hand-water-test-appliance (Optional) N.A. on COMFORT and COMPACT Models
The hand-water-Tester measures how much ppm of the TDS is still in the water. The value
from the World-Health-Organization, WHO, for good drinking water, is 500 ppm.
ppm = parts per million TDS (total dissolved Solids)
Pressure gauges
The pressure gauge shows how much pressure the high pressure-pump delivers. The work-
area is between 800 and 950 psi.
High pressure-pump
The high pressure-pump pumps waters through the membrane
Flow meter
How much drinking water is produced in the hour shows the flow-meter.
(In U.S. gallons per hour) 1 U.S. Gallon = 3.78 liters. 2
Pressure Regulator
The pressure control allows the operator to regulate the pressure. 800 psi is normal.
Sea-water-filters (option) for BASIC and STANDARD
The sea-water-filter keeps back coarse particles and spares the booster-pump and the pre-
filter consequently.
Pre-filter
The pre-filter has a permeability of 20/5 microns and filters the fine particles.
Sample Valve (option) N. A. for COMFORT and COMPACT Models
The sample-valve enables to take a water-test directly at the exit of the system. This is to the
control the water quality so that one can prevent the influx of bad water.

Cleaning-valve (mounted at the pressure regulation)
This valve enables, either a flow over board (Normal Flow), or a recirculation for cleaning and
preservation. (Cleaning Flow) See flow diagram.
Fresh-water –flush system (FWS)
The fresh-water –flush system provides flushing the system when not in use, with fresh
water, just with a turn of the handle at the selector valve. The build in changeable carbon
filter cartridge prevents that chloride exits the membrane. The handle must be installed below
the waterline if you install the system acc. Page 12. When installing acc. Page 12a all
components except the boost pump can be mounted over the waterline. Flushing the system
extends the lifetime of the membrane and is used for short time storage. (up to10 days)
