Start-Up Procedure - Phcbi MDF-DU300H Manual De Instrucciones

START-UP PROCEDURE

Follow this procedure for the initial operation of the unit and for consequent operations (after temporary
stoppage for cleaning, maintenance or moving) .
After a power failure, the unit will restart operation automatically with the same settings as before the
power failure [page 20]
1. Check that the following switches are turned off: [power switch, battery switch, switch of the optional
back-up cooling kit (if installed)] .
2. Connect the power supply cord to the dedicated power source with the appropriate rating with the
chamber empty.
3. Turn on the power switch .
► When the power is switched on, the high-temperature alarm is activated. The alarm indicator and the
temperature display blink. (This is not a malfunction.)
The high-temperature alarm will be cancelled when the chamber temperature reaches the approximate
o
set temperature [(factory setting): -80 C].
When operation of the unit is started in high ambient temperature, the filter check indicator may lights
up. The indicator will turn off automatically when the ambient temperature decreases.
4. Turn on the battery switch.
<Important>
Always turn the battery switch on when the unit is operating to ensure that the power-failure alarm is
working.
5. Set the desired chamber temperature [page 21].
The factory setting of chamber temperature is -80 o C.
6. Using the temperature display, check that the chamber temperature has cooled to the set temperature.
Check that the chamber temperature falls to the set temperature when the start-up after cleaning,
maintenance or moving.
7. Turn on the switch of the optional back-up cooling kit (if installed).
8. Press the alarm test key (ALARM TEST) to check the alarm operation.
► The alarm indicator blinks and the buzzer sounds. The remote alarm is also operated.
The alarm indicator (ALARM) blinks and "E09" appears on the temperature display if the battery switch
is off.
9. Press the test switch of the optional back-up cooling kit (if installed) to check it is working.
10. Gradually place the material inside the chamber.
Putting a large amount of material into the chamber at one time causes the temperature to rise.
11. Set the alarm temperature [pages 23 - 24] and the buzzer suspended period [page 25], lock the
chamber temperature setting [page 22], and the compressor delay [page 26] as required.
