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) and adequate structural support.
- Mount Indoor Unit: Securely mount the indoor unit bracket to the wall using appropriate anchors for wall type.
- Install Refrigerant Pipes: Connect refrigerant pipes between indoor and outdoor units, ensuring proper insulation and avoiding sharp bends.
- Electrical Connection: Connect to a dedicated circuit with proper grounding according to local electrical codes.
- Drainage Installation: Install drain hose with proper downward slope (minimum 1/100 gradient) to ensure proper water drainage.
- Vacuum and Charge: Evacuate air and moisture from refrigerant lines using vacuum pump, then charge with specified refrigerant amount.
- Test Run: Perform test operation to check cooling/heating functions, drainage, and verify no refrigerant leaks.

DRY Mode
Dehumidifies air while maintaining comfortable temperature
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Unit not starting | 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 leaking indoors | Clogged drain pipe, improper installation slope | Clear drain pipe, ensure proper drainage slope |
| Unusual noises | Loose parts, debris in fan, ice formation | Tighten components, clean unit, check for ice buildup |
| Foul odor | Dirty filters, mold growth in drain pan | Clean filters and drain pan, use anti-bacterial treatment |
| Remote not working | Dead batteries, signal obstruction, sensor issue | Replace batteries, ensure line of sight, check sensor |
