Wiring WARNING: All grounding and safety equipment must be in compliance with applicable codes, ordinances and accepted safe practices. NOTE that the oven must be directly hardwired to the disconnect switch on the equipment panel. Please see the picture for the wiring conduit (rear and front). A conduit opening is provided at the rear of the oven.
HEPA Filter Installation Model numbers that begin with the designation LL*1-* are without HEPA filter. If your oven is a LLC*-3 or LLD*-3, disregard instructions of the HEPA filter. Technicians responsible for installing the filter should use caution. The filter is delicate and must not be damaged during installation. Any filter unit dropped, whether or not in the carton, should be examined for damage. Equally important, the filter unit must be installed so that unfiltered air will not leak past the unit.
3. • Check the corner joints of the frame for adhesive sealing and tightness. • Check that the gaskets are cemented firmly to the filter frame and that the gasket pieces are butted or mated at the joints. Pull the shelf out from the oven and set it aside. NOTE: Make certain that power is disconnected from the oven before removing or replacing the HEPA filter. 4. Loosen the two screws at the upper and lower corners of the right rear of the chamber.
is used at temperatures above 180°C / 356°F. There will be smoke, possibly a pungent odor, and a light residue on interior surfaces. This is the result of oxidation of the binder. Most of the binder will leave the filter after running at a temperature of 260°C/500°F for 48 (forty-eight) hours. Check the oven for particles or the exhaust for smoke and odor to determine that the process is finished.
NOTE: If it is necessary to move the equipment after the burn-off process, considerable care should be used. The binder which gives strength to new filters is now burned-off and the media is very fragile. Rough handling of either the filter alone or the equipment with the filter installed is not recommended as it may tear the media and lead to reduced filter efficiency. Removal of the filter after heating can also result in damage to the frame seal, and is only recommended when replacing the filter.
OVEN OPERATION Oven The stackable LCC oven is a class 100 clean room oven with HEPA (High Efficiency Particulate Air) filtration. This oven is ideal for processes where minimization of contamination is essential. Forced convected airflow provides rapid uniform distribution of heat. A HEPA (High Efficiency Particulate Air) filter is mounted in a stainless steel frame in the supply plenum. These filters are 99.97% effective in filtering 0.3 micron particles.
System Control A Despatch Protocol Plus controller/high-limit device is used to control the unit. This is located on the control panel of the oven. • The Protocol Plus controller provides temperature control for the process. • The Protocol Plus controller provides outputs for the cooling fan, door lock switch/door release pushbutton, and optional beacon light. • As many as eight (8) profiles for oven heating cycles are stored in the Protocol Plus controller.
Upper Portion of Control Panel (optional beacon light installed) Secondary Chamber Lock Power ON Switch Door Release Pushbutton Main Disconnect Switch Lower Portion of Control Panel Manual Unlock: In the event of power failure, a torx tip tool (provided) may be inserted and rotated 90 degrees counterclockwise to allow the chamber door to open. It must be turned back to the locked position to allow electrical operation again.
HEPA Filters HEPA (High Efficiency Particulate Air) filters are used to limit particulate size in the work chamber to 0.3 microns or less. NOTE: Chamber temperature transitions must not exceed 1.5° C/minute in order to maintain class 100 chamber conditions in the LCC models. for ramp rates greater than 1.5° C/minute and up to 5° C/minute, the LCD model will maintain class 100 chamber conditions. Definitions HEPA - High Efficiency Particulate Air Burn-Off - A process for getting rid of the binder and D.O.P.
Handling The filter is shipped in the original carton or package that the filter manufacturer uses. This will give good storage and maximum protection from dirt and moisture. HEPA filters should be stored and moved in the shipping carton with in the upright position. Handling should be kept to a minimum. During installation the filter should be removed from the shipping carton and installed directly into the oven.
Validation Testing Based on the issues discussed in this section, Despatch recommends the following test sequence for pharmaceutical Class 100 ovens. 1. Proper installation of the HEPA filters. 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. The Necessity of the Burn-off Process HEPA filters contain a binder material, which protects the filter media during production and shipping.
• Water droplets in airstream through filter, free water (RH = 100%), will saturate filter very quickly and may cause burnout or holes in burned off filter media. • High level of radiation in the vicinity of the filter unit.
HEPA Filter / Magnehelic Pressure Gauge The LCC Series oven is equipped with a Magnehelic pressure gauge which measures the pressure in front of the HEPA filter. As the filter becomes dirty, the pressure will increase. Despatch recommends changing the filter when the pressure is 1” w.c. greater than when the filter was first installed.
OPERATING Users and operators of this oven must comply with operating procedures and training of operating personnel as required by the Occupational Safety and Health Act (OSHA) of 1970, Section 5 and relevant safety standards, and other safety rules and regulations of state and local governments. Refer to the relevant safety standards in OSHA and National Fire Protection Association (NFPA), Section 86 of 1990.

Press the Menu key.
Zone Calibration Page (Defaults on Page 71) The Zone Calibration Page allows adjustment of the displayed temperature versus the actual temperature measured by the control thermocouple. This may be desirable in certain conditions where the center of the oven chamber is not the same temperature as the control thermocouple. This may occur when the oven is not allowed to soak at a constant temperature for long periods of time, or the oven is being used at high temperature.
As an example, the control is displaying 400°F with the setpoint being 400°F, but the center of the oven chamber is actually 395°F. This can occur due to oven wall losses and product loading variations. The operator may change the zone calibration so that the center of the oven is 400°F when the display re ads 400°F. In this case operate the oven in manual mode with a setpoint of 400°F. Recor d the center of the chamber (as measured with an independent sensor).
Sensor Calibration Page (Defaults on Page 71) The Sensor Calibration Page has parameters which can change the internal calibration of the temperature sensor input signal.
