Diesel Combi Heater Installation
Installation of fuel lines
1. The distance from the oil suction pipe to the bottom of the fuel tank should not be less than 25 mm.
2. Type A oil suction pipe should take oil from the top of the tank. Hole diameter is 25 mm. Type B oil suction pipe generally takes oil from the white skeleton of the fuel pump assembly. The opening diameter is 6.5 mm. No matter which oil suction line is selected, it is not allowed to take oil from the bottom or side wall of the tank.
3. The blue oil delivery pipe should be installed between the fuel tank and the oil pump, with a length ranging from 0.5 to 1.2 meters.
4. The fuel filter must be installed vertically after being filled with fuel.
5. The oil delivery pipe in the oil pipe joint must be cut flat with a sharp knife, and there must be no gap between the oil delivery pipe and the oil suction pipe, fuel filter, oil pump, buffer, oil check valve, and main engine oil inlet pipe (metal).
6. The oil pump with buffer must be installed horizontally, and the oil outlet end of the buffer cannot be lower than the oil inlet end of the oil pump.
7. The white oil pipeline is installed between the oil pump and the main engine, and the length ranges from 2 to 7 meters.
8. The type of A~E clamps is 8-10mm, and the corresponding oil pipe joint is 3.5/9.5mm (thin). The type of J and K clamps is 12-14mm, and the corresponding oil pipe joint is 4.1/10.5mm. Other clamp models are 9-11mm, and the corresponding oil pipe joints are 4.1/10.5mm.
9. Gasoline engines need to be installed with oil circuit check valves. The mark on the oil check valve should be consistent with the direction of fuel flow.
10. The oil pump with buffer must be installed horizontally, and the oil outlet end of the buffer cannot be lower than the oil inlet end of the oil pump.
11. The oil delivery pipe in the oil pipe joint must be cut flat with a sharp knife, and there must be no gaps between the oil delivery pipe and the oil suction pipe, fuel filter, fuel filter, oil pump, buffer, oil circuit single valve, or the oil inlet pipe (metal) on the main engine. There are gaps.
Installation of the water supply pipeline
Under the action of the vehicle suction pump, the cold water enters the water tank of the main engine through the pressure relief valve and the quick connection pipeline.
The heated hot water is led to the faucet and the like through the hot water pipeline connected by the water inlet valve for use by the passengers.
1. Pressure relief valve. There are two functions, one is when the pressure in the host water tank reaches 0.35MPa, the excess pressure is released to the outdoors from the pressure relief port connection pipeline. two is When the pressure of the suction pump reaches 0.35 MPa, the excess pressure will flow from the pressure relief port Connected lines are released to the outside world. Therefore, the output pressure of the suction pump is required It should be less than 0.35 MPa.
2. Antifreeze drain valve. When the ambient temperature of the antifreeze drain valve reaches 1~4°C,
Its internal valve automatically opens, and the water in the host water tank is discharged through the pipeline To the outside, to prevent damage to the water tank and pipeline of the main engine due to freezing.
3. Ball valve. It is used when it is necessary to drain the water in the water tank of the host.
4. Water intake valve./ water tank exhaust valve. When the antifreeze drain valve or the ball valve discharges water to the outside, the waterway pressure decreases, the waterway intake valve opens, and air enters the water tank of the main engine, making it easier to discharge the water in the water tank.
Installation of electrical wiring
1. Power cord (12V)
The power cord must be connected directly to the battery. It is forbidden to connect to electrical components such as relays to prevent the power supply from not giving out current.
The length of the power cord (12V) is 4 meters. If it needs to be extended, the power cord must be replaced and the following conditions must be met.
1) If a power cord with a length of 4 to 5 meters is required, a power cord with a cross-sectional area of 4 square millimeters must be replaced.
2) If a power cord with a length of 5 to 8 meters is required, a power cord with a cross-sectional area of 6 square millimeters must be replaced.
3) Do not use power cords longer than 8 meters.
2. The fuse on the host is 20A.
3. Window short wiring. Available as an extended function.
4. External temperature sensor. Should be mounted on a vertical wall with free air flow all around, typically above the vehicle's passenger door, on the inside. When installing, a round hole with a diameter of 10mm should be opened on the installation surface, and just put it in.
5. LCD switch. The LCD switch should be mounted on a vertical wall for easy operation. Open a 74mm×84mm opening on the vertical wall first, then fix the switch frame, and finally fix the switch on the switch frame.
6. Power cord (220V). When you choose to use 220V electric heating, you need to connect to 220V mains.
7. Oil pump leads. The plugs at both ends should be securely fixed to prevent loosening.
Installation of intake and exhaust pipes
1. The exhaust pipe is installed in the intake pipe, one end is fixed on the exhaust port of the main engine, and the other end is fixed on the intake and exhaust port body.
2. The intake pipe is installed outside the exhaust pipe, one end is fixed on the air intake of the main engine, and the other end is fixed on the intake and exhaust port body. The middle part of the intake pipe needs to be fixed with clips to prevent vibration.
3. The intake and exhaust outlet body is installed on the vehicle wall, and it is forbidden to install on the vehicle floor.
Installation of heating pipes
1. The host must be connected to 4 independent heating pipes, and each heating pipe must be connected to at least one air outlet.
2. If one air outlet is connected to each heating pipe, when the main unit is in the heating state, the four air outlets must be fully opened to avoid overheating of the main unit.
3. When the length of the warm air pipe is less than 50 cm, the warm air pipe must be folded into a "U" shape and cannot be straightened.
