3.7 Advantages of the Energy recovery system
Introduction
Thank you for choosing a Schenker Watermaker.
As all the equipment, the knowledge of operating and maintenance procedures allows to use the system in the
best way, and to guarantee a perfect functioning throughout the years. We invite you to read carefully this
manual and to keep it for a quick reference.
Functioning principles
The Schenker watermakers, as alternative to the high-pressure pumps of traditional systems, utilizes the
ENERGY RECOVERY SYSTEM patented device, which amplifies the pressure of common low-pressure
pumps, and recoup all the hydraulic energy back from the membranes, allowing an high energy efficiency.
The lack of high-pressure pumps makes the system silent and vibrations free, and enormously simplify the
use because no adjustment is necessary for its operating.

Energy Recovery System It is the black, carbon fibre unit. It has the function to amplify the pressure supplied
by the pumps and to recoup the hydraulic energy back from the membranes. The ERS device makes periodic
cycling by a hydraulically controlled automatic valve. The cycles are noticeable through a ”beat” issued
periodically by the watermaker unit. The unit is based on cylinders and a central body containing the hydraulic
valve necessary for the system functioning.
Manometers. It is located on the front panel of the watermaker, and it measures the working pressure of the
watermaker.
Flowmeter. It is located on the front panel, and it measures the fresh water instantaneous capacity sent to the
tank. The device accuracy is +/- 20%.
Pulsation dampener is a black plastic cylinder, installed in the watermaker. Its function is to reduce and
stabilize the pressure peaks during the watermaker functioning. The device has to be pre-charged with air
through the specific valve. The air pressure precharge is about 4 Bar. The pressure dimmer is charged in
factory at the right pressure.
Depressurization valve. It is used for the air bleeding of the unit. It is recognizable by a blue lever and it is
located on the right fitting of the third membrane. Its function is to depressurize the system and to allow the
bleeding of air. The valve must be closed during normal working conditions (vertical position), and it is opened
during the air bleeding operations (horizontal position).
Positioner. It is a stainless steel threaded arm, with a black knob, located on the right side of the watermaker.
Its function is to reset the unit in case of hydraulic block.
Reset valve. It is installed next to the watermaker right front corner and it is recognizable by the little blue
plastic lever. The valve must be closed during normal functioning (lever perpendicular to the valve). Such valve
has the function to allow the reset of the ERS in case of a system block. It must be opened before acting on
the valve positioner.
High pressure switch. It Is hydraulically connected with the pump group. It stops the system if the pump
pressure exceeds 9,5 bar. In this case a high-pressure alarm is activated on the control panel.
Probe (pressure switch). It is a device, hydraulically connected to the left side on the main valve of the Energy
Recovery System. Its function is check that the cycling of the machine is correct. It is set at 2 bar.
Electric box. It contains all the electric and electronic devices necessary for the functioning of the system and
the protection of the components.
It is connected to a remote control panel that allow to control the whole function of the watermaker.

4. MOUNTING AND INSTALLATION
4.1 General criteria
Before starting with the installation, it is important to carefully plan all the activities, by evaluating all the possible
solution to be adopted. The main points to focus on are the following:
•Individuate the seawater inlet
•Positioning of the main units (pump group, watermaker group, active carbon filter).
•Positioning of the magnetothermic switch.
•Passage of the pipes and electric cables.
CAUTION
For a correct installation of the watermaker, in order to avoid issues along the different ways
of operating condition, please follow carefully the general instruction below:
•Consider to install the through-hull fitting in a central and deep position, in the way that no air
could be aspirated.
•The non-return valve has to be installed under the seawater level and as close as possible to
the through-hull fitting, in vertical position.
•The pump must be installed as low as possible respect to the seawater level and as close as
possible to the seawater intake (through-hull fitting).
•The watermaker unit must be horizontally positioned, and arranged on an adequate support
which is able to sustain the weight (about 50 Kg).
•Provide to leave a space of about 20cm on the left side of the watermaker unit in order to allow
the passage of inlet and outlet (discharge) pipes.
CAUTION
The pump group must be installed in a ventilated place, in order to facilitate the cooling. In
addition to this, a place not exposed to condensation and dripping should be adopted.
ATTENTION
The external surface of motor and pump can reach high temperature; therefore, it is
recommended to avoid any contact with inflammable liquids and materials.
NOTE
Once individuate the correct installation solution, it is recommended to first make a schematic
draft of the hydraulic and electric connection, and attach them to the present manual for future
needs as first reference.

4.2 Components mountings
4.2.1 Pump group
The diaphragm pumps are a self-priming type, so the pump group may be installed relatively above the
seawater level. Anyway, it is suggested to install the pump group as low as possible respect to the seawater
level and as close as possible to the water inlet; furthermore, the pump cannot run dry. Therefore, it is very
important avoiding to start the system if the intake valve is closed or if inlet filters are clogged.
The pump group should be installed in an adequately ventilated room, with the purpose to facilitate the cooling
of the motor, and not subject to condenses or drippings. The max permitted room temperature must not
exceed 45°C.
Avoid the contact or the proximity with inflammable material or liquid, since the motor surfaces can reach
elevated temperatures. Avoid locating the pump wherever a possible loss of water can involve damages or
jeopardize its safety. The pump must be installed on a base sufficiently horizontal, suitable to sustain the
weight of the group. The pump is normally fixed on the support structure by passing bolts.
4.2.2 Watermaker group
Concerning the watermaker unit installation there are not height limits respect to the seawater level. Anyway,
it should be installed above both pumps.
Avoid to install the system wherever any possible leak may cause damages to the boat or jeopardize its safety,
since possible leaks due to accidental causes (pipe bursting, hose clamp loosening, equipment failure, etc.)
may cause water losses.
The hydraulic intake and outlet connections are positioned on the left of the unit. Therefore, it is necessary to
foresee a minimum distance of 20 cm. to allow the pipes laying. The watermaker unit must be installed on a
base sufficiently horizontal, suitable to sustain the weight of the group. The max allowed room temperature
must not exceed 40°C. It is advisable to install the unit in such position to make the instrumentation easily
visible, and make the valves (located on the right of the unit) easily accessible. The watermaker is normally
fixed on the support structure by passing bolts.
4.2.3 Accessories
The non-return valve has to be installed vertically as close as possible to the seawater intake, following the
direction of the arrow.
The active carbon filter (and the attached electrovalve) has to be placed next to the pump group, if possible,
on a vertical side easily accessible.
4.3 Installation
4.3.1 Water intakes and discharges
For a correct installation of the watermaker it is necessary to arrange the following water intake and discharge
out of the board:
•Seawater intake.
•Fresh water intake for washing.
•Brine disharge.
