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, you can purchase a longer lineset separately. Please see the "Additional Line Sets" section above on this page. 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 between60°F and 86°F—depending on your comfort.
