Hot air circulation oven manuals A 1.Must pay attention to the supply voltage can meet the 1 before use. When in use, must be grounded outlet line according to the rules to stop grounding. 2.in electricity use, electric local avoid touching the space in the box on the left or with a damp cloth to wipe and rinse with water, inspection should be cut off the power supply. 3.Indoor temperature regulator metal pipe not to impact or effect of flexibility. 4.placed box items not too crowded, must leave air natural convection space, the atmosphere in the moist wind top speed to escape. 5.should regularly check the silver contact temperature regulator can hairy or not, if available, spinning cloth will contact sand flat, and then use, and should often clean cloth wipe, make contact with excellent (note must cut off the power). Indoor temperature regulator metal pipe not to impact or effect of flexibility. 6.in the absence of proof mounting boring box, do not put combustible goods. 7.after each use, must be cut off the power of local, often insist on the inside and outside clean. Clean end suspension corresponding identification. B 1.explosive and inflammable volatile items do not put in the dry box, lest cause explosion. 2.sample shelf uniform load should not exceed 20kg. 3.sample chamber and the heating chamber shelf cannot be placed items, so the impact of heat exchange. 4.Must reflect on Ni Cr wire has no stack, short circuit between the 4 before use. 5.heating indicator light does not shine, the reason has three: first, ordinary light bulb out of the bulb; bad contact; the heating system out of order. 6.open the heating switch, without heating.Reason four: the ordinary nichrome wire circuit; the switch from line sealing off; the temperature control knob to zero (the temperature control knob to the specified temperature scale); the relay protection. 7 temperature control failure, the reason has three: the ordinary temperature probe protection (change of thermistor); ② relay protection; the temperature control system with other components (with a multimeter measure the problem, subject to repair). 7.temperature control failure, the reason has three: the ordinary temperature probe protection (change of thermistor); ② relay protection; the temperature control system with other components (with a multimeter measure the problem, subject to repair). C 1.using the Hot air circulation oven manuals must be a person responsible for the equipment used should be cut off, at the end of an external power supply, avoid accidents happen. 2.indoor placed sample, cannot too close, lest affect the general activity of indoor air mission, there shall be 10 ~ 20mm gap between each item, and are symmetrically placed, each layer of the shelf items to interweave, the bottom shelf interval and task room must have more than 100mm interval. 3.the equipment should be left around a certain space, easy to heat and control and protection equipment. 4.avoid sharp, sharp objects scratch equipment. 5.do not disassemble the electrical components and equipment on the other (Department), lest the protection of electrical power lines, man-made faults of equipment and its function. 6.storage, use of equipment, surrounded by non flammable, explosive and corrosive spirit. 7.no flammable, explosive and volatile items will be put in the equipment stop boring disposal. 8.use please read the "manual" carefully equipment before, and then stop the manipulation.
