(1) After unpacking, please carefully check whether the product accessories are complete and damaged according to the packing list. If you find any problems, please contact the dealer for replacement.
⑵ Check whether all parts of the product are installed correctly and whether the screws are tightened, so as to avoid possible damage during transportation and affect the use of the product.
2. Determine the installation location
The range hood should be installed right above the cooker, coaxial with the cooker, and the left, front and rear positions should be horizontal. The distance from the bottom of the range hood to the surface of the cooker should be 650~750mm (the side suction machine can be reduced appropriately (200~400mm, depending on the specific use), and the range hood should not be installed in a place with strong air convection. Find out the installation position of the hanging plate of the range hood on the wall, draw lines with a pencil, and ensure the installation level of the range hood with a level when drawing lines.
3. Fix the hanging plate of the engine hood
Drill holes in the installation position and fix the cigarette hanging plate attached to the packing box on the wall with cross screws.
4. Hang the engine hood on the hanging plate.
Hang the range hood on the hanging board to ensure that the range hood does not shake and unhook, and try to ensure the level.
5. Install the smoke exhaust pipe
Connect one end of the smoke exhaust pipe to the air outlet on the range hood, and the other end to the hole closely related to smoke consumption on the external wall (as shown in the figure). If the flue gas is discharged to the * * * flue, don't insert the exhaust pipe too deep to increase the exhaust resistance; If the smoke is discharged to the outside of the wall, it is suggested to add a louver on the outside of the smoke exhaust pipe to prevent the net backflow to the room. At the same time, please make sure that the exhaust nozzle protrudes by 30 mm
Step 6 Install the oil cup
Screw or push the oil cup into place and fix it.
7, debugging range hood
Press the "power" key and the "lighting" key, and the left and right lights will light up. Press it again, the key will pop up and the light will go out. Press the "high speed" switch, the motor will run at high speed; Press the "low speed" key, the motor will run at a low speed and can run circularly; Press the "Stop" key and the motor will stop running.
1. Preventive measures
(1) The gas discharged from the range hood should not be discharged into the hot flue for discharging the flue gas burning gas or other fuels to prevent fire.
(2) The range hood shall be used when the stove consumes gas or other fuels, and the room must be well ventilated.
(3) It is forbidden to directly bake the range hood with fire.
(4) Reliable grounded power sockets must be used.
(5) If the power cord is damaged, it must be replaced with special wires or special parts purchased from its manufacturer or maintenance department.
(6) If the method specified by Mingzhu is not clear, the range hood is in danger of catching fire.
(7) When replacing bulbs, please unplug the power supply first, and the power of each bulb shall not exceed 20W.
(8) When cleaning, please wear rubber gloves to prevent metal parts from hurting people, and the removed parts should be handled with care to avoid deformation.
(9) Special care should be taken when cleaning the wind wheel. Don't bump, deform or move the counterweight of the blade, otherwise the whole machine will vibrate and the noise will increase.
(10) Unplug the power cord when it is not used for a long time.
2.？ Working principle of range hood
Deal_h3 ("near-suction range hood")
The working principle of the range hood is that the range hood is installed on the upper part of the cooker, the power supply of the range hood is connected, and the motor is driven to make the wind wheel rotate at high speed, so that a negative pressure zone is formed in a certain space above the cooker. Indoor oil fume gas is sucked into the range hood, filtered by the oil net, separated for the first time, and then enters the air duct of the range hood for the second time through the rotation of the turbine. The oil fume in the wind cabinet is subjected to centrifugal force, and the oil mist condenses into oil droplets, which pass through the oil path.
Deal_h3 ("automatic control principle of range hood")
In the figure, the gas sensor and W 1 form a gas detection circuit, and the AC 5V voltage output by the power transformer heats the gas sensor heating wire. InveRter F 1, W2 and thermistor rt form a temperature detection circuit. The high potential signals output by the two detection circuits control the motor control circuit composed of F2, F3, R2, VT2 and J 1 through isolation diodes VD8 and VD9 respectively. Photosensitive resistors CdS, W3, F4, R3, VT3, J2, etc. Constitute a lighting control circuit; IC 1 is a music alarm circuit, which is controlled by a gas detection circuit.
Component selection IC 1 KD956 1 integrated circuit; For f 1 ~ F4, the integrated circuit of CD4069 is selected. Transistor 90 13 is selected for VT 1 ~ VT3. CdS photoresistor is selected as the photoresistor; Thermistors are four 330 Ω thermistors connected in series. The gas sensor is QM-N 10. Select other components as shown.
