Electrical Installation, Pump; Making Ready For Winter; Electrical Installation, Level Sensor And Level Gauge - Vetus DWS042 Instrucciones De Instalación

• Fit the tap water supply pipe (18), 12 mm (
eter, between tank and pump.

Electrical installation, pump

The pump is compatible with both 12 and 24 Volts.
The minimum cross-section for the connecting cables is 2.5 mm
(AWG 14). The voltage drop between the battery and the pump
should not exceed 10% of the supply voltage. For a 12 Volt
installation with a total cable length (positive and negative wir-
ing added together) of more than 19 m use cable with a cross-
section of 4 mm 2 . (or more than 50 ft: use AWG 12).
• Connect the power supply as shown in the wiring diagram.
See drawing at page 26.
A main switch* and a fuse** must be incorporated in the posi-
tive cable.
Make sure the + (plus) and - (minus) connections are made
properly!
Red is +, black is -.
*) The switch must be rated for 10 Amps.
**) Fuse: 10 Amps for 12 Volt system
6 Amps for 24 Volt system
The electric motor may become hot when used for a longer
period of time! Make sure that electric wiring etc. does not get
in contact with the motor housing.

Electrical installation, level sensor and level gauge

The previously installed ultrasonic tank level sensor (Art. code:
SENSORA) measures the liquid level without making any con-
tact. The sensor can be used in combination with a Vetus level
meter.
Note: Not included in the delivery.

When the power is switched on the LED on top of the sensor
will always flash green!
Connect the sensor to the tank level meter as shown in the wir-
ing diagrams, see page 27.
The sensor has been calibrated for the internal height of the
tank. Do not connect the yellow wire (Cal), but isolate it.
See 'Use' before making use of the tank.

Warning

Making ready for winter

The tank, pipes, pump, etc. must always be drained completely.
Never put anti-freeze in the tank or other parts of the drink-
ing water system to protect it against freezing, anti-freeze is
very poisonous!

Draining the pressurized water system
• Open a tap so that the pump will run; let the pump continue
to run for about 30 seconds after the tank is empty.
• Disconnect the power to the pump.
Maintenance
Check the breather nipple regularly and clean the sieve of the
breather nipple if necessary. Check the hoses and hose connec-
tions for possible leaks annually and fit new hoses and/or hose
clamps as necessary.
Also check the tank for damage as a result of chafing. Replace
a damaged tank immediately.
Carry out the disinfection procedures described under 'Use' at
the beginning of the sailing season.
A tank and installation that is strongly contaminated by algae
can be cleaned by rinsing the tank, the pump and pipes with
chlorine water.
