This guide, drawing upon expert knowledge and industry best practices, aims to equip service personnel with the essential safety precautions for handling FFUs.

1. Fundamental Safety Principles

a. Environment:

  • Strictly adhere to indoor usage: FFU are designed for controlled indoor environments and may malfunction or experience reduced lifespan under extreme outdoor conditions.
  • Strategic placement: Avoid installation at room corners to prevent deformation and ensure proper airflow.
  • Structural integrity: Verify that the ceiling structure can safely support the weight of the FFU.
  • Environmental hazards: Protect FFUs from prolonged exposure to low temperatures, high humidity, oily smoke, flammable or explosive environments, as these can compromise their safety and performance.

b. Electrical Safety:

  • Qualified personnel only: Wiring and electrical work must be entrusted to licensed electricians to minimize the risk of personal injury and malfunctions.
  • Grounded connection: Ensure the power supply cord is connected to a socket with a proper grounding wire for optimal safety.
  • Malfunction response: In case of malfunction, immediately turn off the FFU, disconnect power, and notify a qualified professional for maintenance.
  • Modifications prohibited: Never alter the electrical circuit without authorization to avoid potential accidents like fire or electric shock.
  • Live maintenance discouraged: Avoid servicing the FFU while it is connected to the power supply.
  • Long-term storage: When an FFU is out of service for an extended period, disconnect the power cord from the socket.

2. Operational Safety Measures

  • Power down before installation: Always completely disconnect the power supply before initiating FFU installation or removal.
  • Protective gear: When handling FFUs, wear appropriate Personal Protective Equipment (PPE) such as gloves, safety glasses, and respiratory protection if necessary.
  • Lifting assistance: Utilize proper lifting techniques and equipment, especially for heavier FFUs, to prevent injuries.
  • Maintenance schedule: Adhere to a regular maintenance schedule for filter replacements, performance checks, and cleaning to ensure optimal operation and safety.
  • Training: Ensure personnel handling FFUs receive proper training on installation, operation, and maintenance procedures, including emergency protocols.
