Symbols used The unit must only be installed and repaired by an expert. Symbol indicates a possible hazard. Comment including information and tips. Observe the ESD regulations! An electrostatic charge can destroy the electronics. Ensure potential equalisation before touching the electronics.
– The use of upright gas cylinders from which gas is taken in the gas phase is mandatory for the operation of gas regulators, gas equipment and gas systems. Gas cylinders from which gas is taken in the liquid phase (e. g. for forklifts) must not be used, since they would result in damage to the gas system. – The operating pressure for the gas supply is 2.75 kPa and must correspond to the operating pressure of the appliance (see type plate).
– Guarantee claims, warranty claims and acceptance of liability will be ruled out in the event of the following: – modifications to the unit (including accessories), – modifications to the exhaust duct and the cowl, – failure to use original Truma parts as replacement parts and accessories, – failure to follow the installation and operating instructions. Function description The Combi 2 E / 4 E (Australia) liquefied gas heater is a warmair heater with integrated hot water system (10 litre capacity).
P&T relief valve (Pressure and temperature relief valve) Operating instructions Read the safety instructions and operating manual carefully before starting the unit. Risk of scalding injury from hot water and/or tampering with the P&T relief valve! –– Do not actuate the P&T relief valve as long as the appliance is still hot. –– Do not place a plug or reducing coupling in the discharge pipe (Fig. 3a - 19a) of the P&T relief valve. –– Do not operate the water heater without a functioning P&T relief valve.
Draining the hot water system If the motor home / caravan is not used during the winter, the hot water system must be drained! No warranty claims for frost damage will be accepted. –– Switch off the power to the pump assembly (main switch or pump switch). –– Open hot water taps in kitchen and bathroom. In order to check the water that is flowing out, place an appropriate container (capacity 10 litres) beneath the drainage socket (d) of the drain valve.
Overheating protection 240 V Faults The operation of the overheating protection 240 V indicates a possibly dangerous situation. Do not reset the overheating protection 240 V until the water heater has been serviced by a qualified person. Faults – Heater Descriptions of possible fault causes and a troubleshooting guide can be found in the operating instructions for the control panel that is installed. The 240 V heating facility has a mechanical overheating switch.

Truma warranty policy The warranty is given by Leisure-Tec Australia Pty. Ltd., 50 Metrolink Circuit, Campbellfield, Victoria, 3061, Australia for 12 months from the date of purchase against any defect arising from faulty materials or workmanship. Repairs will be carried out during normal business hours only by Leisure-Tec Australia Pty. Ltd., or its duly authorised service agents, and are subject to the warranty conditions and exclusions hereunder.
Installation instructions Selecting a location The unit and its exhaust duct must always be installed so that they are easy to access at all times for service work (e.g. gas and water connection via a service flap, furniture doors etc.) and are easy to remove and install. Read the installation instructions carefully prior to starting work and observe the instructions! Non-compliance with installation instructions or incorrect installation can result in endangerment of persons and property.
10* Securing the device 1 180 350* 2 10* 10* 10* 500* Check whether the vehicle has a load-bearing floor or false floor for securing the heater. If the floor is unsuitable, create a load-bearing surface beforehand by gluing a plywood board to the floor, for example. Screw heater to vehicle floor or false floor using four B 5.5 x 25 screws (included in scope of delivery).
The ducts must be cut to length so that they protrude from the hole for the cowl after installation. The exhaust duct (1) must be 10 % longer than the combustion air intake duct (5). This avoids exhaust duct expansion and tensile load. 5 1 Connecting the exhaust double duct to the device Compress exhaust duct (1) at its beginning so that the coils lie next to each other. Slide clip (4 – claws toward unit) over exhaust duct (1). Slide clip (7) onto combustion air infeed (5).
If the warm air duct has to be subjected to a considerable amount of bending immediately behind the warm air outlet of the unit in confined spaces, we recommend the use of the BGC 90° elbow (part no. 34091-01). This elbow makes it possible to connect a ÜR warm air duct with a diameter of 65 mm or a VR warm air duct with a diameter of 72 mm. For connection to 8 mm steel piping Leisure-Tec provides an adapter UNF 1/2" x RVS 8, part no. 70020-02700. 8 20 m m F UN 2" 1/ 21 Fig.
As accessories Truma supplies the water connectors (27 + 28) and drain valve (24) with a 10 mm / 3/8" diameter hose nipple. The included elbow fittings (27 + 28) must always be used in order to completely empty the water and prevent the water pipes on the unit from leaking over the long-term! Elbow fitting (28 – with aeration valve) is connected to the upper warm water connection; the second elbow fitting (27) is connected to the lower cold water connection.
a maximum overall length of 10 m using 2 x 0.5 mm² cable if necessary). 32 28 The provided room temperature sensor must always be connected, otherwise the heater will switch to fault. Installing the control panel The installation of the control panel is described in the instructions included with the control panel. 29 27 20 mm 45º Fig.
Electrical connection 230 ~ / 240 V ~ – option – All electrical work and permanent wiring must be carried out by a qualified person in accordance with the standards AS/NZS 3000, AS/NZS 3001 and all local codes and regulatory authority requirements. Fig. 32 According to Standard AS/NZS 3001.2008 “Electrical installations – Transportable structures and vehicles” all electric circuits must be protected with an RCD (residual current device).
