Special attention:

The proper use of refrigeration coefficient will directly affect the normal operation and temperature control precision of the equipment.

4.Priciples on the setting of refrigeration coefficient:

4.1.If the equipment is needed to work at thermostatic state under the temperature that is within the range of ambient+5 --60 , the refrigeration coefficient should be set to be 2 . (To lower the starting temperature control point, the ventilation cover on the side or back of the equipment should be removed and rotate the window to make it open. If ambient is relatively low and the ascent of temperature is too slow, the ventilation cover can be removed when the temperature reaches the preset value.)

4.2.If the equipment is needed to work at thermostatic state under the temperature that is within the range of 4 -- ambient+5 , the refrigeration coefficient should be set to be 0.5 and rotate the window to make it close, and close the spiracle.

Special attention:

When the refrigeration coefficient is 0.5 , the compressor will keep running.

Make sure the spiracle is closed. The automatic defrosting program should be started!(Refer to the setting of defrosting program for detailed operational instruction)

5.Improving the temperature control blind area

The electric motor, fan and mechanical friction can produce a certain amount of heat, which can make the real temperature inside naturally rise about 5 without heating. So, the temperature range between ambient and ambient +5 is the blind area of temperature control, unless the compressor is started to control it.

To reduce operation of the compressor, this equipment is equipped with spiracle on the back of the equipment. When the preset temperature is at the blind area, rotate the spiracle to make it open.

After that, the rate of temperature naturally rising will be reduced remarkably.

When the above operation is finished, the working temperature is still at the blind area and the deviation of temperature is relatively large, turn on the compressor and close the spiracle.

7.Temperature exceeding alarm

1.When the deviation between real temperature and preset temperature is bigger than

3 , audio and visual will be activated, the yellow LED indicator twinkles, the buzzer alarms intermittently. If the deviation is positive, heating output will be cut off. If the deviation is negative, refrigerating output will be cut off. The platform will keep oscillating.

2.Press the Temperature button can eliminate alarm for 30 minutes.

3.Reset the temperature can terminate the alarm.

4.When the deviation between real temperature and preset temperature is smaller than

3 , the alarm will be terminated automatically.

3.About the choosing of defrosting timing parameter

3.1.If defrosting timing is set to be 0 , the defrosting program is not started;

3.2.If defrosting timing is set to be 1 , the equipment will start defrosting when the accumulated working time reached 1 hour;

3.3If defrosting timing is set to be 2 , the equipment will start defrosting when the accumulated working time reached 2 hour, and the rest may be deduced by analogy.

4.About the defrosting time parameter:

4.1.If defrosting time is set to be 1 , the equipment needs 1 minute to defrost.

4.2.If defrosting time is set to be 2 , the equipment needs 2 minute to defrost, and the rest may be deduced by analogy..

5.Priciples on the setting of defrosting timing and defrosting time:

5.1.Because of the variance of the ambient temperature, the setting temperature and the time of continuous refrigeration, the setting of defrosting timing and defrosting time should be set according to the accumulation of frost inside the evaporation chamber.

Important attention:

Under normal condition, the defrosting timing can be set to be 6 while the defrosting time 3 . This means the equipment will refrigerate continuously for 6 hour and need 3 minutes to defrost.

5.2.If defrosting operation is end and the accumulation of frost inside the evaporation chamber is still severe, the defrosting time can be extended appropriately.

5.3.When the equipment works continuously under low temperature for a long period of time, the speed of frost accumulation will accelerate gradually because of the humidity increase inside the evaporation chamber. So, shorten the defrosting timing or extend the defrosting time appropriately can solve the problem.

5.4.During the defrosting process, the real temperature inside may have a temporary deviation of 3 and this is a normal phenomenon.

Important suggestion:

For those equipments working under low temperature for a long period of time, it is good for the equipment to be dried thoroughly every 10 days or at the interval of work.

The method: When the equipment is connected with power, open the cover of the equipment, set the refrigeration coefficient to be 2 ,set the temperature to be the highest value, and after these steps, the equipment will conduct dehumidifying operation for 4 hours. The defrosting and refrigerating performance of the equipment will be increased substantially.

1.3.Steps on the adjustment of oscillation amplitude.

1.3.1.Open the cover, put your hands at the bottom of the shaking board assembly and pull it out(need some strength).

1.3.2.Four rubber socket and central eccentric adjusting holes can be seen at the bottom of the equipment.

Hold the diagonal rubber boot with fingers firmly and do circular motion, move the gear (7) showed on the illustration to the central adjusting hole.

1.3.3.Use a box spanner to loose the M6nut (4) on the pinch bolt(3), then use a M6 inner hexagon spanner to anticlockwise loose the M6bolt(9) inside the centre of gear. To avoid the shaking board rotating with the nut, the box spanner can be used to hold the board.

1.3.4.Place the central position of the pinch bolt and make it the central point, use box spanner to rotate the gear. Rotate the gear clockwise to enlarge the oscillation amplitude and anticlockwise to reduce. Use left and right sides(100D type) or front and back sides(200D type) of the chamber as reference, measure the distance the pinch bolt moved. Rotate the gear until the needed eccentric distance is acquired.

1.3.5.When adjustment is finished, tighten the M6 inner hexagon bolt and M6 nut, put the shaking board assembly back to its original place.

1. Shaking Diameter Adjustment

16.1 Instruction of stepless adjustment (MINI – MIDI - MAXI):

Attention:

Power supply must be disconnected before performing the following operations!

These models have an adjustable shaking diameter of Ø0-50mm. To adjust it, please follow the instructions below,

16.1.1. Tools needed: 5mm Allen key, 10mm Socket Spanner, Gear spanner (Included in accessory pack)

Structure illustrations

16.1.2. Turn off the unit, unplug the power code, open the glass door, hold platform tray from the bottom firmly and pull the whole shaking tray assembly out. (you do need some strength)

16.1.3. Turn the shaking base with four rubber sockets until seeing the center of the shaking mechanism

16.1.4. Use the 5mm Allen key to loosen the inner hexagon bolt (6) on the adjusting kit.

16.1.5. Keep M6 Allen key on the hex bolt to hold the shaking base as stationary, in the meantime, loosen the 10mm hexagon nut (4) with turning anti-clockwise with the socket spanner

16.1.6. Now the shaking base is free to move along in the slot of the shaking mechanism. Move the shaking base to adjust the shaking diameter. The closer to the central, the smaller the shaking diameter, while the further away from the central, the larger the shaking diameter. Alternatively, rotate the gear (7) with the gear spanner clockwise to enlarge the shaking diameter and anticlockwise to reduce it. Use left or right sides (MIDI) or front and back sides (MAXI) of the chamber as reference, measure the distance that the pinch bolt moves as the shaking diameter. Keep adjusting until the ideal shaking diameter is reached.

16.1.7. One adjustment is finished, tighten the 5mm hex bolt and 10mm nut, and locate the shaking tray assembly back to its original position.
