Fig 11 Fig 12 Attention: For re-installation of the heater , a new gasket must be used to replace the old one. 4.2.5Direction for installation of the heater is shown in Fig.
- Page 12 shall not be smaller than 60mm. Its material shall be capable to resist temperature of 130℃. 4.3.3 The maximum pressure drop between the air inlet side and air outlet side of the air heating system shall not be greater than 0.15kPa. 4.3.4 The hot air from the heating system shall not erupt onto such parts that are unable to resist heat.
- Page 13 4.4 Installation of Fuel Supply System The fuel supply system for the heater is as shown in Fig. 16. 1-Fuel tank 2-Fuel extractor 3-Fuel pipe connector 4-Filter 5-Fuel pipe 6-Fuel pump 7-Damper 8- Non-return value Fig.16 4.4.1 The fuel pump shall be fixed in automobile with a fuel pump clamp with protective rubber cover.
- Page 14 4.4.4 Installation of Fuel Filter A fuel filter shall be installed before the fuel inlet port. Please make sure that the fuel flow is correctly followed. Its position shall be in conformity with Fig. 18. Fuel filter should be changed after 2 years, fuel pipe joints and clamps should also be changed.
- Page 15 sucking in impurities sediment on the bottom of fuel tank. 4.4.6.2 If fuel is sucked from the fuel pipe to the engine, the fuel pipe from the fuel tank to the fuel filter shall be disconnected and re-connected with the thicker pipes of the reducing T and the thinner pipe of the reducing T shall connect the fuel pump of the heater via oil pipe fitting and fuel pipe.
- Page 17 indicator on the case, so as to identify the working conditions (operation/stop) of the heater easily. The plugs on the leads from the control switch shall be connected to the main wire bundle and make self-locking mechanism. Note to remove the knob firstly, then install the knob after fixing the screw.
- Page 18 4.6.3 Both the air inlet pipe and exhaust pipe shall come outwards and downwards from the heater (Fig. 24), otherwise a Φ4mm hole shall be b) Wrong a) Correct prepared at the bottom of the pipe for Fig.24 discharge of condensation water. If the pipe need curve, the radius cannot be smaller than 50mm.Also, the sum of Direction of running vehicle...
- Page 19 5 Methods of Operation 5.1 The heater control with three ways. (1) Use the control switch(normal configuration). (2) Use LCD control switch(optional choice). (3) Use GSM mobile phone controller(optional choice). 5.2 Use the control switch 5.2.1Power on Push air conditioner （ constant temperature） button or heating(constant power) button, then the indicator light of air conditioner（constant temperature）or heating(constant power) flash 0.3S, then lit, said controller has started work, enter the corresponding working mode.
- Page 20 5.2.5 Use any other way shut off the heater (cut off the power) directly is not allowable. 6 Treatment of Usual Troubles 6.1 During use, the heater may become unable to start normally or die out after start. Such troubles may lead to locking state. In such case, you can press the button which is lighting on then work indicator goes out.
