3. Təhlükəsizlik Təlimatları

Always prioritize safety when operating the Robinair 34888HD machine. Adhere to the following guidelines:

• Fərdi Qoruyucu Avadanlıqlar: Always wear safety glasses and gloves during any refrigerant recovery or charging process to protect against chemical exposure and frostbite.
• Həddindən artıq doldurulmanın qarşısının alınması: Always use a scale to prevent overfilling of the recovery cylinder. Overfilling can lead to dangerously high pressures and severe equipment damage. Do NOT fill the recovery cylinder more than 80% of its capacity.
• High Pressure Safety: The machine is equipped with a high-pressure safety shut-off switch that will automatically shut down the unit if pressure rises above 550 PSI, preventing damage and ensuring user safety.
• Düzgün havalandırma: Operate the machine in a well-ventilated area to prevent the accumulation of refrigerant vapors.
