2. INSTALLATION
2.1 Mounting
E4H Series machines are equipped with a stand-alone frame, which supports the machine. At
least 45 inches (114 cm) of space should be allowed on each end of the membrane element
housings for removal and loading of membrane elements. If 45 inches (114 cm) are not
available, the entire membrane element housing may need to be removed for membrane
element replacement.
WARNING!!
A vacuum breaker must be installed at the highest point along the

WARNING:
Connect the concentrate line to the RO machine’s concentrate outlet. A vacuum breaker must
be installed at the highest point along the concentrate line. This provides an atmospheric
break upstream from where the flow enters the drainage system. For systems which include
multiple RO machines, install check valves along each machine’s concentrate line prior to
connecting the lines to a common manifold.
