Installation Guide

Tools Needed:

  • Vacuum pump with gauge manifold
  • Refrigerant charging scale
  • Tubing cutter and flaring tool
  • Torque wrench
  • Multimeter
  • Level
  • Drill with core bit

Step-by-Step Installation

  1. Select Installation Location: Choose a location with proper clearance (minimum 30cm from ceiling, 15cm from walls) and adequate structural support.
  2. Mount Indoor Unit Bracket: Securely mount the bracket to the wall using appropriate anchors for your wall type.
  3. Drill Wall Hole: Drill a 65mm diameter hole through the wall with a slight downward slope to the outside.
  4. Connect Refrigerant Pipes: Connect copper pipes between indoor and outdoor units, ensuring proper flaring and torque specifications.
  5. Connect Drain Hose: Install drain hose with proper downward slope (minimum 1/100 gradient) to ensure proper condensation drainage.
  6. Electrical Connection: Connect to dedicated circuit with proper grounding according to local electrical codes.
  7. Vacuum and Charge: Evacuate the system to 500 microns and charge with specified refrigerant amount.
  8. Test Operation: Test all functions including cooling, heating, fan speeds, and remote control operation.
Warning: Installation must be performed by certified HVAC technicians only. Improper installation may void warranty and create safety hazards.

Key Features

Inverter Technology

Advanced DC inverter compressor adjusts cooling/heating output to match room requirements, providing consistent comfort with up to 40% energy savings compared to conventional units.

3D Airflow

Vertical and horizontal louvers operate independently to distribute air evenly throughout the room, eliminating hot/cold spots and ensuring uniform temperature.

Plasma Quad Filter

Four-stage filtration system removes dust, pollen, odors, and bacteria while deactivating viruses and allergens for cleaner, healthier indoor air.

Wi-Fi Control

Built-in Wi-Fi allows remote control via smartphone app, including scheduling, temperature adjustments, and energy consumption monitoring from anywhere.

Eco Mode

Intelligent energy-saving mode optimizes operation to maintain comfort while minimizing power consumption during extended use.

Self-Clean Function

Automatically dries the heat exchanger after use to prevent mold and bacteria growth, maintaining optimal performance and air quality.

Operation Modes

Cool Mode

Standard cooling operation with adjustable temperature (17-30°C) and fan speed settings

Heat Mode

Heating operation with automatic defrost cycle for efficient operation in cold conditions

Dry Mode

Dehumidification function that removes excess moisture while maintaining room temperature

Fan Mode

Air circulation without cooling or heating, with multiple fan speed options

Auto Mode

Intelligent mode that automatically selects cooling or heating based on room temperature

Sleep Mode

Gradually adjusts temperature and reduces fan noise for comfortable sleeping conditions

Troubleshooting

Problem Possible Cause Solution
Unit not starting Power failure, circuit breaker tripped, remote control batteries dead Check power supply, reset circuit breaker, replace remote batteries
Poor cooling/heating Dirty filters, blocked airflow, refrigerant leak, outdoor unit obstructed Clean filters, clear obstructions, check for leaks, clear outdoor unit area
Water leakage Clogged drain pipe, improper installation slope, frozen evaporator Clean drain pipe, ensure proper slope, check for ice formation
Unusual noises Loose parts, debris in fan, vibration from mounting Tighten all screws, clear debris, check mounting stability
Frozen coils Dirty filters, low refrigerant, fan motor failure Clean filters, check refrigerant charge, inspect fan motor
Remote not working Dead batteries, signal obstruction, sensor issue Replace batteries, ensure line of sight, check indoor unit sensor
