Selected fi eld pipe sizes must match the recommended sizes in table above. If the installation requires diff erent fi eld pipe
diameter due to diff erent application condition other than recommended, contact ActronAir for advice. Most of unit
pipe connections are factory swaged to easily fi t to the recommended fi eld pipe diameter. When it is required to install
other refrigeration devices, such as refrigerant drier, solenoid valve and the like, include the equivalent straight pipe
length of the device in the calculation of total equivalent fi eld pipe length.
Both pipes are required to be insulated.
A = EQUIVALENT PIPE LENGTH,
60 metres (max)
B = VERTICAL HEIGHT,
20 metres (max)
