Start The Lcc/Lcd Oven - Despatch LCC Series Owner's Manual

LCC_LCD1-16/51 Oven Owner's Manual
6.4.1.3. Validation Testing
Despatch recommends the following test sequence for pharmaceutical Class 100
ovens.
1. Proper installation of the HEPA filters (Section 5.3).
2. Ambient air challenge to determine integrity of oven chamber and filter
gaskets.
3. Proper filter burn-off procedure.
4. Class 100 testing inside the work chamber.
6.4.1.4. HEPA Filter Burn-off Process
HEPA filters contain a binder material which protects the filter media during
production and shipping. Smoke produced from burning this binder at elevated
temperatures is undesirable during normal oven operation. Burning off the binder
will ensure a clean process at elevated temperatures.
However, when the binder is burned out of the filter media, the filter becomes
very fragile: too fragile to withstand normal shipping and handling. For this
reason, Despatch does not perform the burn-off procedure. The burn-off process
is not necessary at temperatures consistently under 180°C. Refer to Section 5.3.3
for information on burn-off process.

6.4.2. Start the LCC/LCD Oven

1. Turn the yellow/red DISCONNECT SWITCH to ON (Figure 20).
2. Press the POWER for ON.
a. The DOOR RELEASE pushbutton will illuminate. This means the door can be
opened.
During the process cycle, DOOR RELEASE will not be lit, meaning

that the oven door may not be opened. To unlock the door, press
STOP or remove power from oven using the DISCONNECT SWITCH.
b. For Optional Beacon Light-equipped Units Only: The amber (center)
beacon light will illuminate, indicating that the oven is ready to receive work
to be processed.
