The external motor access platform shall ship loose for assembly and installation by the installing contractor. 8
OPTIONAL EQUIPMENT Single Side Inlet Connection The EDX is available with a Single Side Inlet option which eliminates external pipework, valves and field balancing associated with the standard (2) inlet design. Internal PVC pipework is utilized to relocate the water inlet to the side of each cell. The connection is standard with a hole and bolt circle pattern, other options are available. Note: Multiple cell installation will require adequate space between towers to allow for piping, unless the bottom inlet option is selected. If a tight, side by side layout is required, the EDX is available with an optional Bottom Inlet Connection. The inlet is located on the bottom of the cold water basin and allows the inlet pipework to run underneath the unit. Note: Adequate space is required underneath the unit for pipework. Please consult the factory for certified drawings indicating connection size and location.
