Pre-Installation Mandatory Requirement

• 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.
• 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.
