Drain joint installation
NOTE: Drain joints differ slightly according to the different
outdoor units. Inspect your unit and use the installation in-
structions for your specific unit.
For drain joints with seals (Figure 15A):
• Slide the seal onto the drain joint and insert into the
base pan hole of the outdoor unit. Rotate 90° to secure
(see Figure 16).
For drain joints without seals (Figure 15B):
• Insert the drain joint into the base pan hole of the out-
door unit until it remains fixed, accompanied by a click-
ing sound.
NOTE: For protection against water condensation off the out-
door unit during heating mode, connect the drain joint with an
extension drain hose (provided by the installer)

Refrigerant Pipe Connection
NOTE: The main cause of refrigerant leaks is due to defective
flare connections.
Make flare connections using the following procedure:
1. Remove the flare nuts attached to the indoor and out-
door units. Before flaring, slide them over the tubing. It
is not possible to put them on after flaring tubes.
