Installation Guide

Tools Needed:

  • Vacuum pump with manifold gauge
  • Torque wrench
  • Flaring tool set
  • Tube cutter
  • Level
  • Drill with masonry bits
  • Refrigerant scale
  • Leak detector

Step-by-Step Installation

  1. Select Installation Location: Choose a location with proper clearance (minimum 30cm from walls and ceiling) on a solid wall that can support the unit's weight.
  2. Install Wall Bracket: Securely mount the outdoor unit bracket using appropriate anchors for the wall type (concrete/brick/wood).
  3. Drill Wall Hole: Drill a 65-80mm diameter hole through the wall with a slight downward slope to the outside for drainage.
  4. Mount Indoor Unit: Install the indoor unit mounting plate level on the wall, ensuring proper distance from ceiling and obstacles.
  5. Connect Refrigerant Pipes: Flare copper pipes properly, connect to indoor unit first, then route through wall to outdoor unit.
  6. Electrical Connection: Connect power cables according to local electrical codes. Ensure proper grounding and circuit protection.
  7. Connect Drain Pipe: Install drain hose with continuous downward slope to ensure proper condensation drainage.
  8. Vacuum and Charge: Evacuate the system using a vacuum pump, then charge with the specified amount of refrigerant.
  9. Test Run: Perform complete system test including cooling, heating, and all operational modes.
Warning: Installation must be performed by certified HVAC technicians only. Improper installation can cause equipment damage, reduced efficiency, and void warranty.

Troubleshooting

Problem Possible Cause Solution
Unit not starting Power outage, 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 refrigerant leaks
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, clean fan blades, check mounting stability
Error codes displayed Sensor failure, communication error, system malfunction Refer to error code chart, contact service technician
Foul odors Dirty filters, mold growth in drain pan, stagnant water Clean filters and drain pan, use air purification mode

Common Error Codes

  • E0: Protection device activated - Check for obstructions, wait 3 minutes
  • E1: Indoor PCB error - Power cycle unit, contact service if persists
  • E3: High pressure error - Check outdoor unit ventilation, clean condenser
  • E5: Overload protection - Reduce load, check power supply voltage
  • E6: Communication error - Check wiring between indoor/outdoor units
  • U0: Refrigerant shortage - Check for leaks, proper refrigerant charge
  • U4: Indoor/outdoor communication error - Check connection wiring
  • H3: High pressure sensor error - Contact service technician
