Note (1): Equivalent length is the converted length after taking into account of pressure
losses at elbows.
Equivalent length = actual pipe number of elbows x equivalent length of
each elbow
Equivalent length of every place of branch pipe is 0.5 m, and please refer to the
following table for equivalent length of elbows.

Precautions when breaking through the knockout
● Do not damage the unit shell when trying to break through the knockout.
● Smooth the burrs around the hole and apply anti-rust paint after opening the
knockout with a mallet or other tools.
● When passing the wire through knockout, put grommet in the hole or wrap wires with
adhesive tape for protection.
