Selected field pipe sizes must match the recommended sizes in Table 2. If the installation requires different field pipe
diameter due to different application condition other than recommended, contact ActronAir for advice.
Most of unit pipe connections are factory swaged to easily fit to the recommended field 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 field pipe length.
Both pipes are required to be insulated.
