Note the use of a vacuum oven:

1. The vacuum tank shell must be effectively grounded to ensure safety.

2. The vacuum box should be relative humidity ≤85% RH, non-corrosive gases around, no strong vibration source and the presence of a strong electromagnetic field environment.

3. vacuum box Studio No explosion and anti-corrosion treatment, can not be easy to put natural, explosive, corrosive gases items dried.

4. The vacuum pump can not work a long time, so when the degree of vacuum to dry goods requirements, the vacuum valve should be closed, and then close the vacuum pump power, to be less than the degree of vacuum dried goods requirements, and then open the vacuum valve and pump power, continuing the vacuuming, this extends the service life of the vacuum pump.

5. items such as wet and dry, then vacuum between the tank and the pump filter is preferably added to prevent wet gas into the vacuum pump, causing pump failure.

6. After drying items such as dry change of light weight, small size, should evacuation port deadening plus net working indoors, to prevent drying and damage aspiration pump (or electromagnetic valve).

7. After the vacuum box after repeated use, it will produce the phenomenon can not be evacuated, and you should replace door seals or door casing adjustment buckle on the Reach to resolve. When the vacuum oven drying temperature is higher than 200 ℃, it will produce slow leak phenomenon, this time open the box behind the cover with a hex wrench to loosen the heater base, replace seals or tighten the heater base to solve.

8. If the bleed valve rubber stopper rotation difficulties, including may be coated with an appropriate amount of grease.

9. In addition to maintenance, the cover can not open the box on the left (except 6090 and 6210) in order to avoid damage to the electrical control system.

10. The vacuum box should be kept clean. Avoid using glass door reactive chemical solution to clean, use a soft cotton cloth.

11. If the vacuum box not long, exposed to the plating painted neutral after wiping grease to prevent corrosion, and wear a dust cover plastic film, placed in the drying room, so as not to damage the electrical components from moisture, impact use.
