FAQs
What kind of refrigerant does this use?
This unit uses R454B refrigerant. This unit comes pre-charged with R454B refrigerant for up to 75 feet of lineset. If your installation does not exceed this length, no additional refrigerant is needed.
Can I get longer extensions for this installation kit?
Yes, for multi-zone units, you can go back to the product options to select different lineset lengths for each indoor unit.Please note, if the extended lineset is longer than 75 feet, additional refrigerant will be required. Make sure to consult a professional HVAC technician for proper installation
When the unit is in auto mode, what will the room's temperature be maintained at?
In auto mode, the unit automatically switches between cooling and heating to maintain the set temperature. You can adjust the target temperature manually—typically between 60°F and 86°F —depending on your comfort.
Do the condenser lines come pre-vacuumed or do they have to be vacuumed?
The mini split condenser and lines are not pre-vacuumed. You will need to vacuum the system during installation to remove air and moisture before releasing the refrigerant—this is essential for proper operation and longevity.
