• Any work involving connection or interconnecting wiring must be carried out by a licensed electrician. If the
mains cable (supply cord) is damaged, it must be replaced by the manufacturer, its service agent or similarly
qualified persons in order to avoid a hazard.
• Before accessing terminals, please ensure all supply circuits are disconnected (i.e. 230 V – 240 V and 12 V)
and that the gas supply is securely turned off.
• The operating pressure for the gas supply is 2.75 kPa (AUS – Propane) and must correspond to the
operating pressure of the appliance (see data plate).
• LPG systems and pressure regulators must comply with the technical and administrative regulations of
the country in which the appliance is used. For your own safety it is absolutely necessary to have the
complete gas installation regularly checked by an expert (at least every 2 years). The vehicle owner is always
responsible for arranging the gas inspection.
• Do not operate when travelling.
• Do not operate the water heater when refuelling the vehicle and when it is in the garage.
• Items sensitive to heat (e. g. spray cans) must not be stored in the installation area, since excess
temperatures may occur there under certain circumstances.
• During the initial operation of a brand new appliance (or after it has not been used for some time), an
amount of fumes and a slight smell may be noticed for a short while.
Always observe the operating instructions prior to starting!
The vehicle owner is responsible for correct operation of the appliance.
Before using the product for the first time, it is essential to flush the entire water supply through with clean
warm water. Always mount the cowl cap when the water heater is not being operated! Drain the water
heater if there is a risk of frost! Warranty claims will not be accepted for frost damage.
Always remove the cowl cover prior to operating the water heater.
If connecting to a central water supply (rural or city connection) or when using more powerful pumps, a pressure
reducer must be used which prevents pressures of greater than 400 kPa occurring in the Truma UltraRapid.
Filling the Truma UltraRapid with Water
Check that the drain valve (3) and the P&T safety valve (Fig.2a - 4) in the cold water intake are closed.
•
Close drain valve (Fig. 2 - 3). Lever in the “e” position (close).
• Test lever (Fig. 2a - 4a) of the pressure relief valve (4) must be in the “close” position.
– Open hot tap in bathroom or kitchen, with pre-selecting mixing taps or single-lever fittings set to “hot”.
– Switch on power for water pump (main switch or pump switch).
– Leave the tap open to let air escape while the water heater is filling. The heater is filled when water flows out of
the tap.
