Connection Electrical Supply and Remote Control

The water heater is designed for 12 VDC (10…15V, negative ground). The power leads are on the

back of the heater and should be connected via a breaking switch to the 12 V system of the RV. The

red wire is positive (+) and the black wire is negative (see sticker). A breaking switch is recommended

for safety reasons, so the water heater could be switched of separately.

If the leads need to be extended or any wiring is extended or replaced inside the heater, use a

minimum of 0.5 mm² wire with a temperature rating of 105°C. It is suggested that the heater be

connected to a breaker rated at 5 amps.

DO NOT connect heater to a power converter without a battery in line or a battery charger. Doing so

could damage your heater and void the warranty. Be sure that the heater is connected to a "filtered"

(pure DC) circuit of the converter. To test whether the circuit is pure DC, take a voltage reading using a

multimeter set on the AC voltage scale. If the reading is more than 1 volt, the circuit is not pure DC

voltage and should not be used. (See the tag on red and black power wire on the back of heater)
