This document provides a comprehensive maintenance manual for the BIOBASE Vertical Autoclave Sterilizer, BKQ-B Series, model number XDGF2017-010. The manual is issued by BIOBASE BIODUSTRY (SHANDONG) CO., LTD, located at NO. 51 SOUTH GONGYE ROAD, JINAN, SHANDONG, CHINA.

The BIOBASE Vertical Autoclave Sterilizer is designed for sterilization applications, utilizing steam to achieve high-temperature sterilization. Its primary function is to sterilize various items, ensuring they are free from microorganisms. The device is equipped with a control panel for operation and display of status, including temperature and pressure.

Usage Features:

The sterilizer operates through a series of steps, including heating, sterilization, and cooling. It features a door detection switch to ensure the door is properly closed during operation, preventing accidental opening while the machine is running. The device includes a water level float to monitor the water level within the pot, which is crucial for the heating process and preventing dry heating of the heating tube. Users can adjust parameters such as the ending temperature of exhausting cold air, which is set to between 101-103 degrees Celsius by default, to optimize sterilization based on specific needs and environmental conditions. The manual provides instructions for accessing and modifying these parameters through the control panel. The device also incorporates safety features such as a pressure gauge, a relief valve, and a safety door interlock to ensure safe operation.

Important Technical Specifications (inferred from context):

While specific numerical technical specifications are not explicitly listed, the manual implies several key aspects:

Sterilization Method: Vertical steam sterilization.
Temperature Range: Capable of reaching temperatures above 100°C for sterilization, with a typical ending temperature for exhausting cold air around 101-103°C. The ambient temperature for proper sensor function is indicated to be above 10°C.
Pressure: Operates under positive pressure conditions, with a safety valve set to release at 0.22 MPa.
Control System: Features a circuit board for controlling various functions, including heating, temperature sensing, and alarm management.
Safety Mechanisms: Includes a pressure gauge, safety valve, door detection switch, water level float switch, and temperature protector to ensure safe and reliable operation.

Maintenance Features:

The manual emphasizes a systematic approach to inspection and repair, starting with identifying the major fault and then progressively narrowing down the cause. It advises operators to gather information about the machine's usage history, previous maintenance, and specific symptoms before attempting repairs. A critical aspect of maintenance involves reviewing maintenance records to track replaced parts and consumables.

The manual provides detailed solutions for various alarm codes (Err 001, Err 002, Err 004, Err 008, Err 016, Err 032, Err 064, Err 128), which indicate specific malfunctions:

Err 001 (Leakage phenomenon): Requires checking pipeline connections and seals under positive pressure.
Err 002 (Bad heat pipe, unreasonable setting parameters): Involves checking the heating tube for dryness/blackening and verifying cooling air time settings. It also covers parameter adjustment for temperature and pressure discrepancies, and restoring factory settings if environmental factors affect parameters.
Err 004 (Leakage): Similar to Err 001, focusing on pipeline connections and seals, and also addresses circuit board failure due to wet environments.
Err 008 (Sensor fault or ambient temperature too low): Requires checking ambient temperature and the bottom temperature probe. If the display is abnormal, the sensor is faulty. The solution involves changing the sensor.
Err 016 (Circuit Board Temperature Sensor Failure): Indicates a circuit board burn-out, requiring replacement of the circuit board.
Err 032 (Not enough water in the set time): Suggests adding water and checking the water level floater for damage.
Err 064 (Drying heat pipe): Points to issues with the water level float, solenoid valve, or overload use. Solutions include checking the float, anti-dry thermostat, and solenoid valve for proper function or blockages.
Err 128 (Door opened while machine running): Indicates a broken door detection switch, improper door closure, or a loose nut on the door shaft. Solutions involve replacing the switch, re-closing the door, or fastening the nut.

Replacement Procedures for Electrical Components:

The manual outlines steps for replacing key electrical components, emphasizing the importance of cutting off power and ensuring no pressure inside the sterilizer before any operation. These procedures are intended for qualified personnel.

Safety Valve Replacement: Involves removing the retainer screw, replacing the valve, and testing the sterilization process. Regular checks (every two months) are recommended to prevent blockages.
Thermostat Replacement: Requires removing wiring from the main circuit board, accessing the thermostat at the bottom of the pan, and replacing the probe. The thermostat acts as a temperature alarm, automatically turning off the heater if the pot temperature exceeds allowable values.
Heating Tube Replacement: Involves removing wiring, loosening captive screws, and replacing the damaged heater.
Water Level Float Replacement: Requires removing wiring from the circuit board, accessing the float at the bottom of the pan, and replacing it.
Temperature Sensor Replacement: Involves removing wiring from the main circuit board, accessing the sensor on the side of the pan, and replacing it. The manual provides detailed instructions for checking sensor resistance using a multimeter (normal value about 109Ω).

Cleaning and Maintenance:

Daily: Clean the door apron with a soft cloth or gauze, wipe the inner wall of the sterile container with gauze and detergent (avoiding steel slag or brushes), and remove scale.
Weekly: Wipe the sterilizer cover with a soft cloth and check the safety valve.
Monthly: Tighten connectors and check on-off status (by a professional electrician).
Annually: Inspect the door lock device for wear and tear.

The manual also includes electrical wiring diagrams (Appendix 1) and pipeline wiring diagrams (Appendix 2) to assist with troubleshooting and maintenance, providing a visual guide to the internal components and their connections.
