Overview

This document is the installation manual for an AKAI 2.5kW Reverse Cycle Inverter Split System Air Conditioner, model number AK-T25R32.

Function Description:

The AKAI 2.5kW Reverse Cycle Inverter Split System Air Conditioner is designed for cooling and heating rooms. It operates as a reverse cycle inverter split system, meaning it can both cool and heat, and its inverter technology allows for variable compressor speed, leading to more efficient operation compared to traditional on/off systems. The "split system" designation indicates that it consists of two main units: an indoor unit and an outdoor unit, connected by refrigerant pipes and electrical cables. The system uses R32 refrigerant, which is an odourless hydrocarbon gas with a high level of environmental compatibility, significantly lower global warming potential (GWP), and zero ozone depleting potential (ODP).

Usage Features:

The indoor unit features a front panel, LED display, deflectors for airflow direction, and a remote control for operation. The remote control allows users to select various modes (MODE), eco-friendly operation (ECO), set timers (TIMER), adjust fan speed (FAN), activate sleep mode (SLEEP), control display settings (DISPLAY), manage swing functions (SWING), mute the unit (MUTE), activate health functions (HEALTH), use "I FEEL-CLEAN" (likely a self-cleaning or comfort feature), and set turbo mode (TURBO) or other settings (I SET).

Maintenance Features:

The manual emphasizes that installation and maintenance must be performed by appropriately qualified and licensed installers due to the flammable R32 refrigerant and government regulations.

  • Refrigerant Handling: The appliance is factory-charged with R32 refrigerant. Any recharge must be done by a professional installer. Maintenance technicians must perform a safety inspection before any work and strictly comply with all instructions and gas-related laws.
  • Leak Detection: Special tools like a leak detector are required for maintenance, with specific error margins (not more than 5% for fixed-type, 10% for portable). Concentration detectors must be calibrated regularly.
  • Vacuum Pump: An explosion-proof mini vacuum pump (vacuum degree lower than 10Pa) is required for bleeding air and humidity from the refrigerant circuit.
  • Filling Device: A special explosion-proof filling device with a precision deviation of less than 5g is needed for refrigerant filling.
  • Pressure Gauge: Pressure gauges used for R410A can be used for R32 and should be calibrated regularly.
  • Fire Extinguishers: Dry powder, carbon dioxide, and foam fire extinguishers must be available at the maintenance site, placed in stipulated, eye-catching, and handy positions.
  • Post-Installation Checks: After installation, the service technician must:
    • Check that air cannot enter the refrigerant system.
    • Check for refrigerant leaks when moving the air conditioner.
    • Carry out a test cycle under controlled conditions and record operating data.
  • Filter Accessibility: The indoor unit should be installed where the filter is easily accessible for cleaning or replacement.
  • Drainage: The condensed water drain pipe must slant downwards to aid drainage and should not be bent, protrude, twist, or have its end in water.
  • Disposal: Packaging materials are recyclable. The air conditioner contains flammable refrigerant and must be removed by municipal authorities or recycling facilities. Electrical and electronic components should not be disposed of with household rubbish due to their potential environmental and health impact.

Safety Precautions (for installers):

  • Do not install the unit in environments with gas, oil, sulphur, near heat sources, or within 50cm of flammable substances.
  • Ensure proper ventilation in the installation area to prevent refrigerant gas accumulation.
  • The outdoor unit base must be firmly fixed.
  • Disconnect all power circuits before accessing terminals.
  • Verify mains voltage matches the rating plate.
  • Ensure the socket is suitable for the plug.
  • The appliance requires a means for disconnection from the supply mains with contact separation in all poles for full disconnection under overvoltage category III conditions, incorporated into fixed wiring.
  • Do not expose the appliance to high heat, sparks, or open flames. Do not pierce or burn the appliance.
  • Store the appliance in a room without continuously operating ignition sources.
  • Only professional installers should recharge refrigerant.
  • Maintenance must be carried out under controlled procedures to minimize risks from combustible gas/vapour.
  • The room for installation must be larger than 4m² (suitable for 10-15m²).
  • Avoid open fires, welding, smoking, drying ovens, or heat sources above 548°C during installation/maintenance.
  • Mind static electricity; wear protective clothing and anti-static gloves.
  • Do not use a mobile phone during installation.
  • Choose a site convenient for installation and maintenance, ensuring air inlets/outlets are unobstructed and away from heat/combustible environments.
  • Ensure indoor unit inlet/outlets are even.
  • Avoid installing directly under electrical products, switches, sockets, kitchen cabinets, beds, sofas, or valuable items.
  • If an indoor unit refrigerant leak occurs during installation, immediately turn off the outdoor unit valve and ensure personnel leave the room for at least 15 minutes after the leak is fixed.
  • If the product is damaged, it must be returned to a maintenance station; do not attempt to weld refrigerant pipes on site.
