Protocol printing
Printing the protocol with the help of CITIZEN printer, type iDP 3110-24 RF-A. By setting the interval of the printer you determine the time intervals in which the actual value of the temperature in the chamber will be printed. Magnitude of this interval is stated in the heading of the excerpt. Interval of the printer can be set on the display within: t min = 1 minute, tmax = 255 minutes ( 4 hours 15 minutes) by 1 minute. 1. We start from the condition, when the display displays real value of the temperature. Connect the printer to the hot air box by means of the cable with serial connector (RS232C) into the socket for the printer (see (see Fig.4), the other end of the cable connect to the connector in the rear part of the printer.

3. The printer prints the head containing the type of the unit, set temperature and selected time interval. Values of the following data are printed in one line under this heading: time from starting the program and actual temperature in the chamber. 4. Switching the print off is performed by setting the print interval to 0 (symbol ---). 5. In case of change of set operation conditions of the oven or in case of change of print interval a new heading will be printed (this is not valid valid when set interval is 0 (symbol---)). 6. If the power supplying the apparatus fails , after the power recovery the printer prints the sign Power recovery! and the actual temperature value. Time intervals start counting immediately after power recovery. After switching-off and switching-on by means of again a new head is printed. 7. If the power supplying the printer fails or the printer is turned off, no message is printed after turning the printer on again or after power recovery . 8. Setting of the DIP / switches of the printer: all four pins are in lower position OFF.
4.7
Safety thermostat function and setting
Safety thermostat serves to protect the thermal box, its surrounding and treated material against inadmissible exceeding the set temperature (e.g. it prevents damage or destroying of material samples in case of a damage to the temperature regulator or unintentional setting of higher temperature in the chamber of the unit than respective sample is able to bear). In case of correct setting, the safety thermostatswitches off at approximately by 5 °C up to 10 °C, higher temperature than the temperature set on the regulator of the unit. Setting the thermostat: 1. Press the external rotary ring ring of the thermostat towards the control panel and with simultaneous slight pressure turn it to the right (clockwise) up to the limit position (maximum). The center with the knob turn together with the external ring. 2. Thermal box is heated up to required required operation temperature and left to stabilize stabilize for approximately 10 minutes at this temperature. 3. Then turn the ring ring slightly to the right and depress the key of the thermostat. A slight click is heard and indicator safety thermostat stops shining. If the click is not to be heard and the indicator does not stop shining turn the ring slightly more to the right and depress the key again. Repeat this procedure as long as the indictor stops stops shining. Only in such case is the thermostat set onto required temperature. If the unit is set to maximum temperature turn the ring to the right to maximum according to item item 4. Operation of the unit continues.. NOTICE: Used safety thermostatis of class 2 (according to EN 61010-2-010) - mark TWB. When
surpassing set temperature in the chamber, the thermostat switches the heating bodies off and the indicator safety safety thermostat starts shining (the unit does not heat even if the indicator heating shines). Even after the drop of the temperature below set limit of the protection thermostat, heating remains switched off. It is necessary to depress the knob of the safety thermostatto restore the operation. Indicatorsafety thermostat stops shining .

Creation of vacuum in the chamber
Push the hose from the vacuum pump onto the end of the vacuum piping of the unit (Fig.2, position 11) which is accessible through the side cut-out in the superstructure. Connect the mains cord of the vacuum pump into the socket in the shaft of the superstructure and switch the pump on. Set the ball valve on the front panel of the superstructure into the position VAC ON. Value of vacuum begins to rise on the vacuometer in the front panel after several tens of seconds (the needle valve and the door must be properly closed).
4.9
Sealing exchange and door setting
Take the whole sealing off, begin in the middle bottom part. Fix the new sealing on the edge of the chamber, begin in the middle bottom part. Slam the sealing between the chamber and the outer cover. To check up the tighteness place a sheet of paper between the door and the chamber when closing the door. Pull it out slowly, you should feel a stronger resistance. The door is adjustable at four points (see Fig.12): Pins of the lock – on the left front part of the jacket – at the top and at the bottom: these pins can be loosened by means of the lock nut and they can be adjusted forwards/backwards by means of the thread. Door hinge, lower: by loosening the screw M8 at the front on the right side of the foot it is possible to adjust the door forwards/backwards in the horizontal direction. Door hinge, upper 2: after removing the cover of the extension part the screws M8 in the front right corner become accessible. After loosening these screws the position of the door can be adjusted. Adjust the door so that when closed the rubber sealing of the chamber would wou ld fit to the th e sheet of the floating door along the whole perimeter. To check it up place a sheet of paper between the sealing and the metal sheet of the floating door before it is closed, it is possible to take the paper out against a small resistance.

Note: All technical data are related to 22 °C ambient temperature and ± 10 % voltage fluctuations (if not specified otherwise). For other parameters see section Electric connections . ∗ not measured ++ The heat in vacuum is transferred to the goods on the shelves by conduction in the shelves, therefore the mentioned temperature deviations are valid for temperatures on the surface of the shelves, there must be a perfect heat-conducting contact between the temperature sensors and the shelf surface. Goods placed on the shelves must also be in a perfect contact with the shelves, the goods temperature depends especially on their physical properties and on the contact with the shelf.

11.2 Box „Vacustation“
Serves for placing the vacuum pump MZ2C, resp. MD4C (event. another vacuum pump with appropriate dimensions) in the space of the box, the vacuum box Vacucell is placed on top of it. Both elements are screwed together.
11.3 Chemically resistant resistant vacuum pump
For instance membrane vacuum pumps MZ2C (suction power cca 1.7 m 3/h, achievable vacuum cca 9 mbar) and MD4C (suction power cca 3 m 3/h, achievable vacuum cca 2 mbar) are recommended.
11.4 Separator Separator and emission condenser
The separator of the gas/steam exhausted from the chamber is placed between the chamber and the pump (the separating has a favourable influence on the power of the vacuum pump), emission condenser with water cooler is placed on the pump outlet and reduces the amount of emissions of the exhausted gas/steam in the outer space. Both parts are made of glass and are fixed on the pump.
11.5 System of vacuum vacuum control
Consists of the part CVC II and an electromagnetic suction valve. It enables to keep the constant value of vacuum in the chamber and to show the measured values on the display CVC II. CVC II is placed separately outside the box Vacucell and the suction valve is installed in the extension part of Vacucell.
