Pre-Installation Mandatory Requirement

1. Room temperature around machine should preferably be at 25°C with air conditioning or a well ventilated room with an exhaust
    fan. However, the surrounding temperature should not exceed 30°C.
2. Stabilized Input Voltage of 230V AC, 20 Amps. Use of a Servo Controlled Stabilizer is recommended.

Calibration / Validation

i) Calibration
• Temperature sensor probe calibration with traceability to ERTL
• Temperature controller calibration with traceability to ERTL

ii) Validation
• IQ, OQ and PQ documentation and protocols shall be provided with equipment.
• Documentation prepared / developed for Osworld by Premier Validation Ltd. – Ireland, one of Europe’s
   leading validation consultants
• Performance Qualification with Temperature Mapping on site. The Performance Validation Test consists of
   one cycle at any one temperature point for an 8-hour period. Data is collected in printed format from up to six different points within
   the chamber. Temperature uniformity is considered acceptable if the deviation is less than ±1°C of set temperature.

Optional Extras/Accessories

• Oslog Data Storage Device and Oslog 21 CFR Part 11 Compliant Software - Both have been developed exclusively for Osworld by
   M/s Godrej & Boyce Mfg. Co. Ltd.
• Additional high-temperature safety system to cut off all heaters with audio-visual alarm
• Voltage Stabilizer for above unit
• Data Logger: 4 point temp. Data logger with sensors placed at specific points in chamber with printer interface and memory
