SHAPE THE DRAIN HOSE
•
To drain the condensate easily, the drain hose should be angled downward (pitched towards the drain direction
at 1/4" per foot).
•
Figures below from the 2nd to 5th show some incorrect practices.
•
The drain hose may be extended using the hose supplied with the installation list.
STUFF AND SEAL THE HOLE FOR COPPER LINE SET/WIRE and CABLE/DRAIN HOSE
•
Use putty to seal the wall hole.
•
Use a clamp (pipe fastener) to secure the pipe at the specified location.
CONNECT REFRIGERANT PIPES BETWEEN THE INDOOR AND OUTDOOR UNITS
First, connect the copper tubes at indoor unit. Bend the pipes accordingly using pipe bending tools. Do NOT hand
bend the pipes as this could kink the pipe. Extra length is required for future service.
REFRIGERANT PIPES
For a distance other than 25' between indoor and horizontal venting condensing units, refer to the following table for
copper sizes.
