Power Connection

Before introducing any power to the water heater make sure the water heater is filled with water.

240V Installation

1. Power supplies must be on a network with an alternating current of 50 Hz 240V.

2. The water heater is equipped with a standard 10-amp cord and power plug.

3. The socket should be grounded and protected from moisture.

4. The device must maintain circuit breaker protection.

12V Installation (Duoetto MK2 only)

All appliance installations should be only carried out by a qualified individual.

1. Connect the red 5mm large wire directly to house battery or another suitable power source,

depending on the length of your wiring you may need to step up the cabling, we recommend

a 50-amp fuse. Refer to section 9 for appropriate cable sizing.

2. Connect the black 5mm large ground wire to an earth point or a negative battery terminal,

depending on the length of your wiring you may need to step up the cabling, refer to section

9 for appropriate sizing.

3. Connect the small black ground wire to an earth point and the small red wire to a switched

power source; this is crucial for 12V operation of the heater.

Important: To avoid draining the engine crank battery, the red small positive wire must be

connected to a switch or an ignition source. (Applicable for the DUO-10/12V type only).

6. Methods of Usage

Plug in the water heater after making sure it is filled with water.

Turn the thermostat to the desired temperature and switch the heater on. Indicator lights

indicate the heater is functioning.

Water temperature is adjustable from 30°C to 75°C on 240V.

The Duoetto MK2 and Aqueous MK2 water heaters are auto thermostatic. They

automatically cycle on and off when they reaches the set temperature.
