be careful!

The gap between the heater and the bottom of the car can be sealed with foam glue or glass glue. Otherwise, the heat dissipation of the product will be affected, resulting in induction failure, car fire and more serious consequences. Our company will not be responsible.

3. Installation of combustion air duct and exhaust device

Installation of combustion air pipe

The universal mounting kit contains a plastic black intake hose with a diameter of 25 mm.

According to the installation situation, the flexible pipe can be inserted to stretch or stretch to a suitable length. Then fix the air inlet hose to the air inlet end under the heater with a clamp, and fix the other end of the air inlet hose to the car body with an R-type pipe clamp to prevent shaking.

Please note that!

■ the nozzle of combustion supporting air must be kept unblocked and the air must be clean to avoid dust, rain and snow, so as to avoid carbon deposition.

■ the nozzle of combustion air pipe shall not face the displacement direction.

Regularly check whether the intake pipe stops.

Installation of exhaust device

The universal installation assembly contains a metal exhaust pipe, one end of which is fixed on the exhaust port of the heater with a clamp, and the other end of which is fixed on the car body with an R-type clamp to prevent vibration.

Please note that!

The exhaust pipe should be tilted downward, and the discharge of brake condensate should not be blocked by rain, snow and dirt.

■ the exhaust pipe must not be in the forward direction of the vehicle.

■ the exhaust pipe must not go beyond the boundary of the side of the vehicle.

The outlet of exhaust pipe is fixed under the cab to prevent the exhaust from entering the cab through the gap and causing personal injury.

The exhaust pipe shall be completely cut into sections.

When shrinking the exhaust pipe, pay attention to the distance between the exhaust pipe and the intake pipe, so as to avoid the exhaust gas from the intake device being inhaled as combustion air.

be careful!

During the operation of the inverter, it is not allowed to work in the area where the exhaust guide device is located, so as to avoid the burn and scald caused by high temperature exhaust gas. The heater should be turned off first, and it should be carried out after the body is cooled.

The bottom of the car should be sealed to prevent the exhaust gas from the heater from entering the car. It is forbidden to sleep in the car during the operation of the inverter. Our company will not be responsible for any consequences.

The gas discharged from the exhaust guide device belongs to high-temperature toxic waste gas, which should not be inhaled by human body.

4. Installation of heating air duct and precautions

Installation of heating air duct and precautions

1 air inlet top 2 air outlet hood 3 air outlet pipe clamp 4 air outlet pipe

Please note that!

When fixing and fixing the heating air duct, it is not allowed to blow directly to people, animals and temperature sensitive materials because of its large amount of heat radiation, so as to avoid unnecessary injury.

■ high temperature on the hot air duct throughout the operation from the heater.

■ if the heating air duct is not installed, a protective sleeve must be installed on the air outlet side

When installing the heating air inlet, it should be noted that under normal operation conditions, exhaust gas from the engine and heater of the vehicle should not be inhaled, and dust, smoke, etc. should not be penetrated into the heating air.

When circulating air is used for heating, attention should be paid to that the replaced hot air cannot be directly absorbed when installing the circulating air intake.

In case of overload failure, the local air temperature can be as high as 170 seconds and the surface temperature can be as high as 90 ℃ in case of emergency shutdown due to failure. Therefore, only the original high-temperature air duct installed in our company can be used to guide the hot air.

be careful!

The components such as heater and heating air duct must be installed according to the instructions. During the operation of the machine, flammable materials such as quilts should be placed on the machine body and air duct. The air outlet should not be blocked by any objects to prevent fire. Otherwise, our company will not be responsible for any consequences.

5. Wiring and installation

Please follow the following instructions when wiring the heater: pay attention not to damage the insulation of the wire. Should avoid: scratch, discount, clamping, the impact of heat.

Please note that!

■ it must be connected to the battery to avoid the influence of other on-board electrical appliances on the heater before the key door can be disconnected.

When the wires, switches and controllers are placed inside the vehicle, they should be far away from the heating parts to avoid being heated and damp, so as not to affect their functions.

When fixing the wire harness, do not fix the wire harness on the moving and vibrating parts to avoid breaking the wire harness or replacing the connector.

The positive and negative poles of wiring harness can be lengthened without permission.

6. Fuel supply and related connections

Installation angle and height of oil pump

Please note that!

Permanently use the oil pump of the vehicle itself to supply oil to the heater, and the oil pump shall be installed under the heater.

A. The vertical height between the oil pump installation and the highest oil level (the longest is 1.8m);

B. Oil pump installation and minimum oil level, maximum suction head (up to 1m);

C. Maximum lift from oil pump to heater (up to 2m).

Connection of oil pipe

When connecting the oil pipe, insert the oil pump nozzle and oil take-off pipe into the black rubber connecting hose to produce seamless butt joint in the hose, so as to avoid the formation of bubbles in the oil circuit and affect the combustion effect.

TInstallation angle of T-joint:

1, from the fuel tank 2, choose the car engine

Use T-shaped tee to take oil from the oil way of automobile engine near the oil tank.

1. Automobile fuel tank oil take-off pipe 2, to automobile engine oil pump 3, T-shaped tee 4, electromagnetic pump 5, connecting hose 6, oil pipe

1, connector on heater 2, maximum oil pressure height 3, minimum fuel content

a。 Vertical height of oil pump installed under oil tank: a ≤ 3M

b。 Vertical height of oil pump installed above oil tank:

Diesel: B ≤ 1m gasoline: B ≤ 0.5m

c。 Vertical height from oil pump to heater (oil pump should be installed below heater): C ≤ 2m

Safety instructions for auxiliary tubing!

In order to prevent the oil pipe from being damaged or producing noise due to vibration, it must be firmly fixed.

When compressing the oil pipe, attention should be paid to avoid the tension, friction or vibration of the oil pipe caused by the torsion of the vehicle and the movement of the engine, and the appropriate position should be selected for fixation. The oil pump should be far away from the heat source. Do not rotate the heater or automobile engine close to each other. If it crosses or crosses these high temperature pipes, put on the protective hose if necessary.

After all the oil supply equipment is installed and the heater is started up and running again, the connectors of all parts should be checked to see if there is oil leakage.

When the heater is used for the first time, because there is no oil in the oil pipe, it needs to be started many times or use the fuel filling function to suck up the oil before it can work normally.

■ static electricity uses the vehicle's own oil pump to supply oil to the heater

Application requirements of T-shaped tee:

The T-shaped tee must be installed between the original oil pump and the original oil tank. Do not connect between the original oil pump and the engine, so as to avoid the high pressure of the original oil pump will be injected into the injector, causing great danger. For vehicles with the original oil pump installed in the oil tank, T-shaped tee can not be used, but oil extractor should be used.

Precautions for oil circuit maintenance and repair:

Before using the heater every year, check whether the connection of each part of the oil circuit is loose. Check whether the hose and oil pipe are aged. After operation, check whether there is oil leakage in the connecting parts of the oil circuit. If there is any abnormality, it should be handled quickly.

When the heater is used for the first time every year, due to continuous placement, there may be no oil in the oil pipe, resulting in the failure of normal operation of the frequency converter at the previous start, which is a normal phenomenon. After starting again, the fuel pump can work normally after the fuel is sucked up.

5、 Fault code

Note: Nine lamp control switch and voice control switch fault code: LED light flashes 15 times or digital tube displays 15, which means that the air inlet temperature is too high. It is necessary to check whether the air inlet and outlet are internally circulating or the ambient temperature is too high.
