In most applications the installation of the APR on the lead circuit is enough. When both stages are operating, a drop in suction pressure will modulate the lead circuit. When the second stage shuts off, the APR Control will continue to modulate. In some applications the use of an APR on all circuits may be beneficial, please consult our Technical Support Team for assistance.
