Below is a simplified installation guide.
Step 1: Choose the Right Location
Select a wall where the indoor unit will provide optimal airflow.
Ideal locations include:

Ensure there is adequate airflow around the unit.
Step 4: Connect the QuickConnect Line Set
MRCOOL systems use pre-charged refrigerant line sets.
This eliminates the need for:

- Refrigerant gauges
- Professional HVAC handling
Simply connect and tighten the fittings.
Step 5: Connect Power and Test the System
After connecting electrical wiring:
- Turn on power
- Use the remote control or mobile app
- Test heating and cooling modes
The system should begin cooling within minutes.
Real-World Use: Why Mini Splits Work Well in Garages
Garages are often poorly insulated, making them difficult to cool.
