Installation Guide
Tools Needed:
- Adjustable wrench
- Level
- Screwdrivers (flat and Phillips)
- Pipe cutter
- Vacuum pump
- Manifold gauge set
- Torque wrench
Step-by-Step Installation
- Choose Installation Location: Select a location with proper clearance (minimum 30cm from walls and ceilings) on a solid wall.
- Mount Indoor Unit Bracket: Securely mount the mounting plate to the wall using appropriate anchors for wall type.
- Install Outdoor Unit: Place outdoor unit on a level, stable surface with proper ventilation and drainage.
- Connect Refrigerant Pipes: Connect copper pipes between indoor and outdoor units, ensuring proper insulation and no kinks.
- Electrical Connection: Connect to a dedicated circuit with proper voltage (220-240V, 50Hz). Follow local electrical codes.
- Vacuum and Charge: Evacuate air and moisture from refrigerant lines using vacuum pump, then charge with specified refrigerant.
- Test Run: Test all functions including cooling, heating, fan speeds, and remote control operation.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Unit won't start | Power issue, remote control batteries dead, circuit breaker tripped | Check power supply, replace remote batteries, reset circuit breaker |
| Poor cooling/heating | Dirty filters, blocked airflow, incorrect temperature setting | Clean filters, clear obstructions, set appropriate temperature |
| Water dripping indoors | Clogged drain pipe, improper installation angle | Clear drain pipe, ensure proper installation slope |
| Unusual noises | Loose parts, debris in fan, ice buildup | Tighten components, clean unit, check for ice formation |
| Remote not working | Dead batteries, signal obstruction, remote sensor issue | Replace batteries, ensure line of sight, check sensor |
| Foul odor | Dirty filters, mold growth in drain pan | Clean filters and drain pan, use anti-bacterial treatment |
