Initial Startup 27
Cat. No. 01022940
Wiring for Hi-Flo® 22, Hi-Flo® 55e, CSM Softeners and Filters with GBE Controls
For these systems, you must add a 24 VAC relay, part number 01016156, to provide the pretreatment contact.
GBE to Relay: Connect a wire from terminal 5 of the relay to the left terminal of Aux 4 on the GBE softener/filter circuit
board. Connect another wire from terminal 1 of the relay to the right terminal of Aux 4. See Figure 21.
Relay to CP Plus: Connect a pair of wires from the PRE-TREAT terminals on the CP Plus board to terminals 2 and 4 on
the relay. Remove the installed jumper wire when making this connection.

Flush Modes
Line Pressure Front Side Flush Prior to Startup
When main power is first applied to the CP Plus controller, the controller will first wait for a one-hour delay and will then
open the RO inlet solenoid valve and waits for an additional period of one minute. During this one minute, feed water
under line pressure enters the RO, passes thru the pump and flushes through the upstream (feed water side) of the
membranes and then passes to drain. When the one-minute time is elapsed, the controller checks to see if there is suffi-
cient incoming water pressure to operate the RO. If there IS pressure, the controller turns on the main pump and the RO
begins to produce permeate water. If there IS NOT sufficient pressure, the entire process starts over beginning with the
one-hour delay.
