• In the heating period, it should not operate in the area where the exhaust guiding device locates in.
• When operating on the waste gas discharge device, firstly close the heater until all parts are cooled. Wear the protective gloves when necessary.
• Do not take the waste gas.

Installation notes for heating air duct

Heating air duct

• The installation components contain one flexible pipe that the diameter is φ75mm.

Safety instructions

• When paving and fastening the heating air guide tube or hot air outlet, we should not touch it directly due to high thermal radiation or directly blow the humans, animals or thermal sensitive materials with hot air, or it will cause unnecessary damages and injuries.
• In the whole operation process starting from heating, the thermal air conduit will be in high temperature. Therefore, the operation in the thermal air conduit should be avoided in the whole heating process. If the operation in the area is required, firstly close the heater. When all parts are completely cooled, wear the protective gloves when necessary.

Notes

• When placing the suction inlet of heating air, note that the waste gas from vehicle engine and heater should not be taken and the heating air should not permeate the dust and salt fog under the normal operation conditions.
• When heating with circulating air and placing the suction inlet of circulating air, note that the heating air cannot be directly taken in.
• In case of fault caused by heating, the local thermal air temperature may reach 15℃ and the surface temperature may reach 90℃ before shutdown. Therefore, it is allowed to guide the heat air with the high temperature air hose in the company’s installation components.
• When checking the functions, after operating about 10 minutes, the average temperature of discharged heat air which is measured at about 30cm from the outlet should not exceed 110℃(the air suction temperature is about 20℃).
• The heater and air conduit and other components should not be trampled, covered and pressed, Or it will injure the personnel, burn the inflammables or damage the heater.

Safety Instructions of Fuel Straw Pipe Laying

• In order to avoid the oil pipe destroy or give rise to noise due to the vibration, the oil pipe shall be fixed firmly.
• During the laying, please avoid the oil pipe stretching, friction or vibration caused by the vehicle reversing or engine movement.
• The oil circuit shall keep away from the heat source, instead of being laid under the high-temperature environment. Please don’t lay the exhaust pipe or fix the oil pipe along with the heater or vehicle engine at close range. When it is necessary to cross over these pipelines, please keep the enough heat insulation distance and put the protective hose when necessary.
• Please install all oil supply equipment, then, check the adapting pieces and the oil leakage phenomenon after heater has been started and operated for a certain period of time.
• The oil pump which is installed on the vehicle will be prohibited to provide oil for the heater.

1. Joint on the heater
2. Maximum oil pressure height
3. Minimum fuel contents

Notes：

a. The vertical height a when the oil pump is installed below the oil tank shall be 3m maximally.
b . The vertical height b when the oil pump is installed above the oil tank shall be 1m or 0.5m at the most incase of diesel oil or gasoline.
c. The vertical height c from the oil pump to the heater(the oil pump shall be installed below the heater) shall be 2m maximally.

Operating Requirements of T-shaped Triple Valve Body:
In order to avoid the fuel oil injection in the heater and the huge risks under the high pressure of vehicle oil pump, the triple valve body shall be installed between the vehicle oil pump and oil tank, instead of between the vehicle oil pump and engine. The vehicles of which the vehicle oil pump is installed in the oil tank shall apply the deoiler, instead of T-shaped triple valve body, to extract the oil.

Oil Circuit Maintenance and Overhaul Precautions

• Please check whether the adapting pieces of oil circuits have become flexible before using the heater in winter. Check whether the connecting hose and oil pipe have become aging. Check whether the connection between the oil circuits have suffered from electric leakage when the heater has been operated for a certain period of time. Any problems found should be solved promptly.
• When the heater is used for the first time, the heater is likely to be unable to be started during the early several launching due to the long-term unused behaviors. This is the normal phenomenon, at this moment, please start it for several times until the oil pump can suck up the fuel oil.

IV. Operation and Control Mode

Fuel filling

You shall infill the oil circuit via the fuel oil infilling function when you have installed heater host, oil circuit and electric circuit, otherwise, the heater is likely to fail to be started due to the fuel oil absence in the oil circuit.

The fuel oil shall be refueled in the following way: Press the rocker switch for 8 times continuously at the following frequency after connecting the power line correctly, namely, open it for 1 second and close it for 1 second. At this moment, the heater will start the fuel oil heating procedures to continuously send out the drive pulse of fuel metering pump and keep it for 5 minutes. During that period, the indicator on the rocker switch will flicker at the one-second on and one-second out frequency, moreover, the buzzer will make beep. You shall pay continuous attention to the fuel oil’s position in the oil circuit during the refueling period of fuel oil. When the fuel oil has approached the heater oil inlet for 10cm, please turn off the rocker switch to stop the refueling process.
