How to attach the drain cap
1. Insert hexagonal wrench (4 mm).
Left-hand connection with piping
Bend the connecting pipes so that they are positioned within 43 mm above the wall surface. If the connecting pipes are positioned more than 43 mm above the wall surface, the indoor unit may be unstable. When bending the connecting pipe, make sure to use a spring bender to avoid crushing the pipe.
