The Nüve FN Series Dry Heat Sterilizers/Ovens are designed for sterilizing metal and glass materials, as well as heating or drying samples in laboratory settings. These devices offer excellent conditions for sterilization, drying, and heating, ensuring stable temperatures within specified tolerances.
The FN Series operates by maintaining temperatures between 70°C and 250°C. The FN 300, FN 400, and FN 500 models achieve homogeneous temperature distribution through sheet heaters placed on three outer surfaces of the useful volume. In contrast, the FN 400P and FN 500P models feature inner sides made of stainless steel and utilize circular heaters with circulation fans to ensure temperature homogeneity.
The insulation of these dry heat sterilizers/ovens contributes to economical operation and enhances temperature homogeneity. A PID microprocessor-controlled system, coupled with a timer, provides precise operating conditions. An adjustable safety thermostat offers an additional layer of safety.
The microprocessor control system is equipped to detect malfunctions in the temperature sensor or control system. In such events, an alarm system is activated, providing both visual and audible warnings to the user. The device records study data in its memory, which can then be transferred to an external USB memory stick. To prevent unauthorized changes, the parameter settings are protected by a password-enabled menu.
The FN series dry heat sterilizers/ovens comply with various international standards, including ISO 9001:2015, ISO 13485:2016, EN ISO 14971:2012, MDD 93/42/EEC (2007/47/EC), EN 60601-1, EN 60601-1-2, EN 60601-1-6, EN 62304, EN ISO 15223-1, EN 61000-6-3, EN 62366-1, and EN 50419. The device also complies with WEEE Regulation.
Before operating the instrument, users are advised to read the manual carefully. The device should only be used by authorized personnel for its intended purpose. In case of a breakdown, only technical personnel should handle the product.
Upon delivery, it is important to inspect the packing material and the unit for any external or internal damage. Any damage should be reported immediately to the transportation company, as per ICC regulations, this responsibility lies with the customer.
During operation, users must adhere to all warning labels, which should not be removed. The instrument should never be operated if damaged or if its cable is damaged. It should also not be moved during operation.
The installation procedure involves careful lifting and transport due to the device's heavy weight, ensuring it is supported from underneath and never turned over. After unpacking, users should verify that all provided accessories, including the user's manual, electrical cable, shelves, warranty, and shelf carriers, are present.
Positioning the device requires checking for transport damage, carefully lifting it to its designated location, and balancing it on its four pedestals by adjusting their heights. Shelf carriers and shelves should then be inserted. The chosen site must be suitable for users and ensure the sterilizer/oven does not obstruct other spaces or cause damage.
Environmental conditions are crucial for optimal performance. The device is for indoor use only, with an operating temperature range of 5°C to 40°C and a humidity level of up to 80% at 22°C. The maximum height for operation is 2000m, and the ideal temperature range for maximum performance is 15°C to 25°C. To ensure uniform temperature distribution, at most 70% of the shelf surface area should be utilized.
For mains supply, the dry heat sterilizer/oven requires 230V, 50/60 Hz. Users must ensure the supplied mains match these power ratings and provide an extra line if necessary. The device must always be plugged into properly earthed sockets, and a supply fitted with a circuit breaker should be used for protection against indirect contact in case of an insulation fault.
Prior to operation, several checks are necessary:
To switch on the device, the on/off switch is pressed, activating the microprocessor control system. Users should familiarize themselves with the control and display panel functions.
The control panel features a temperature display, time display, encoder button, start/stop button, heating lamp, "operating the program" lamp, data transfer lamp, alarm LED, "end of the program" lamp, USB lamp, and a back/alarm mute button. The temperature display shows chamber temperature, setting values, alarm values, failure codes, and EoF warnings. The time display shows program time values. The encoder button allows increasing/decreasing temperature and time values and confirming selections. The start/stop button initiates or halts operation. The heating lamp indicates active heating. The "operating the program" lamp signals a running program. The data transfer lamp indicates data transfer or software updates. The alarm LED flashes for warnings or errors. The "end of the program" lamp signals program completion. The USB lamp illuminates when external USB memory is connected (supporting up to 8 GB). The back/alarm mute button silences alarms and cancels menu changes.
User settings are password-protected. The default password is "000". Users can change the password, update date/time, and access the operator's menu. Parameters include recording period, lid alarm settings (not used for all FN models), timer set band, buzzer on/off, date/time settings, and password.
Programming involves setting the sterilizer on stand-by, then using the encoder button to select the SET menu. Users can set operating temperature and alarm values. If the temperature exceeds the alarm value, audible and visual alarms activate. Operating time and delay time can also be set. If a delay time is selected, heating starts after the set delay. During operation, pressing the encoder button displays set values for 5 seconds. The time counts up only after the instrument reaches the set temperature.
Upon program completion, indicated by "End" and the "end of the program" lamp, samples can be removed, with caution due to heat. The chamber surface can be wiped clean once cool. The incubator can be left on stand-by or switched off. Operating records are automatically transferred to a connected USB memory stick. It is crucial not to remove the USB memory until the data transfer LED turns off and the audible alarm ceases.
The dry heat sterilizer/oven does not require periodic maintenance by the operator. For any service or maintenance needs, users should contact a Nüve agent.
For cleaning, the equipment must be unplugged and at room temperature. The chamber should be wiped down to remove any spills. A soft brush can be used for cleaning the chamber. The external body can be cleaned with a cloth and mild detergent for difficult dust and dirt. The chamber should be protected against external rust. Users must be cautious of the undesirable effects of chemicals when cleaning.
In case of malfunction, if the dry heat sterilizer/oven does not operate, users should check:
Error codes provide specific troubleshooting information:
In case of any error, the program stops automatically and immediately. Users should contact an authorized Nüve agent for technical assistance.
The device's lifetime is 10 years. Users are encouraged to register their warranty online via www.nuve.com.tr.
