Lineset Installation FAQUpdated 2 hours ago

Introduction

This article covers frequently asked questions regarding lineset installation.  

Can the lineset be angled upward?

Yes. Refrigerant lines can go in any direction, and the indoor and outdoor units can be higher or lower than each other. However, the maximum height difference for the indoor and outdoor units should typically be around 33-50 feet (10-15 m) depending on the model. 

In addition, the indoor unit must have a condensate drain hose connection with a downward inclination. 

Note: The ceiling cassette and concealed ducted versions come with built-in condensation pumps and drains, which can go up to 32 inches (813 mm).

Can the lineset exit from the side of the indoor unit?

Yes. The lineset can exit from the side of the indoor unit if you don’t want it to go out through the back or wall.

How is the lineset properly uncoiled?

• Do not remove the seal caps from the pipe ends until it is time for connection, avoiding contaminants from entering. 
• If the pipe is bent or pulled too often, it will become stiff. Do not bend the pipe more than three times at one point. Be careful not to kink any piping. 
• When extending the coiled copper pipes, straighten them by unwinding gently against a flat surface.
