Choice of 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. fuel and water connection via a service flap, furniture door etc.) and are easy to remove and install. The distance between the unit and surrounding furniture items or vehicle components must be at least 10 mm at all sides (5 mm at the water connection side). There must not be any heat-sensitive materials beneath the unit (e.g.
Exhaust and combustion air ducting Only Truma duct sets (consisting of an exhaust muffler, an extraction air duct and an air intake muffler) must be used for the Combi heater, since the appliance has been type tested with these ducts. Do not pinch or kink these ducts during installation. Fit outer part of cowl Fill groove on outer part of cowl (8) with plastic body sealant (not silicone), then secure outer part of cowl to wall of vehicle with 4 screws.
Always connect gas-tight adapter (18) of exhaust muffler (4) to unit. Replace damaged O-ring (13). –– Slide clamp (22) onto extraction duct (5). –– Slide adapter (18) of exhaust muffler (4) into muff (19) at unit as far as it will go. –– Click the exhaust gas tube attachment CBD (20) into the sockets (19). –– Check that the exhaust gas sound muffler (4) sits correctly. –– Slide extraction duct (5) onto muff (21) and secure with clamp (22).
Warm air distribution Fuel connection Most of the warm air is fed into the floor area of the living compartment via flexible warm air ducts. The heater requires diesel fuel, as per the Australian Fuel Standard (Automotive Diesel). Operation with any form of biodiesel is not permitted. The fuel is extracted from the vehicle fuel tank (see fuel tank removal kit). Please only use the fuel hoses and lines that are included in the scope of delivery for installation.
Installing the metering pump Always install metering pump with the pressure side (delivery direction) sloping upwards. Protect metering pump from heat (max. operating temperature 40 °C), therefore do not install in the vicinity of sound mufflers and exhaust pipes. Metering pump installation position 90˚ Before drilling, always check for underlying / concealed cables, gas lines, frame sections and the like! Then seal the edges of the openings in the floor of the vehicle with underbody protection.
Water connection For operating the hot water system it is possible to use all pressure pumps and submergible pumps up to 280 kPa, also all mixing taps with or without electrical switch.
Installation of the pressure reducer Depending on the scope of supply – pressure reducer A or B has to be installed. Push the venting hose, external diameter 11 mm (47), onto the hose grommet of the venting valve (46a), and lay it to the outside without any kinks. Ensure that the bend radius is not smaller than 40 mm. Pressure reducer A The pressure reducer (40) must be fitted between the drain valve and water pump in accordance with the direction of flow (indicated by arrow).
Electrical connections Route connecting cables in such a way that they cannot chafe. Please also use leadthrough bushings or edge protection profiles where there are sharp edges such as metal panel leadthroughs. The connecting cables must not be attached to or come into contact with metal surfaces, the exhaust duct or warm air ducts. The electrical connections are located under the connection cover (60). The cover can be removed by pressing and simultaneously sliding it in the direction of the arrow.
Control panel / air conditioning system Function check The following connecting combinations are possible. Check all functions of the appliance, as specified in the operating instructions, in particular the water draining function.
