The RO pump connects to P4 (L1) and P5 (L2) RO pump terminals. This output can operate 120/240VAC motors up to
1HP directly.
The inlet solenoid valve connects to P6 (L1) and P7 (L2) inlet terminals.
The feed pressure switch is connected to the pressure fault input. Low pressure (factory preset 8 psi) will shut system off.
In systems with pretreatment, a pretreat lockout switch can be connected to the pretreat input. This switch should operate
when the pretreatment device is out of service.
Note: The output from the pre-treatment device must be a dry contact and must not supply voltage.
In systems with a level or pressure switch, the switch can be connected to the tank full input.
