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. Must ensure fuel extraction
without any pressure and extract the fuel smoothly when the car is stopping. The
angle for installation must in conformity with Fig. 21, or normal work of the heater
will be affected.
After installation, the vehicle engine shall be started and then turned off after one
minute's work to eliminate air trapped in the fuel sucking pipe.

4.5 Installation of Electrical System
4.5.1 The wiring diagram for the heater is shown in Fig. 22. The wires of the main
heater for connection to outside circuits have been made into wire bundles. They can
be laid according to the positions of various components and shall be fixed in some
proper locations. The distance between two fixing points shall not exceed 30cm.
Attention: Any exposed wire bundle out of the vehicle body or out of the wiring
groove must be protected by corrugated pipe.
4.5.2 Connection of the main wire bundle with the heater: Use a blunt tool to pry the
places marked " ○
Connect the 18-wire connector X6 of the wire bundle to the controller socket. The
wire bundle can come out from either the right
side or the left side of the heater. Then replace the junction box cover. Make sure to
have good sealing between the junction box cover and upper cover and between the
junction cover box and the wire bundle sealing mat to avoid any thermal malfunction
due to leak of air from the hood-shape case.
4.5.3 Straighten the fuel pump leads (two 0.6mm
positive and negative) with their protective pipes, which is made a coil inside the
combustion supporting air inlet port , and put them through the opening on the wall of
the air inlet pipe. Connect the insert of fuel pump connector with fuel pump(Insert the
right position).Cutting fuel pump leads is forbidden.
4.5.4 Use four self-tapping screws to fix the control switch in a position for
convenient operation and the arrangement shall make easy observation on the
Reducing T
"of Fig.4 gently to remove the junction box cover (Fig. 4-1).
