Installation Instructions for the RIA10-1-SAA Control Panel for use with NT25-P18
The high level float switch can be wired to be N.C. or N.O. in the NT25-P18. It is factory wired
to be OPEN (N.C.) on HIGH LEVEL. See figure 2 and 3 below. Disconnect the power before
starting. The electrical ratings for the high level switch on the NT25-P18 are
125 or 250VAC
6A, 125V DC 0.4A, 250V DC 0.3A
1. Extend the two white wires from the high level float switch and push the cable through the
strain relief fitting on control panel and connect wires to terminals 1 and 2 on terminal strip.
Tighten strain relief nut to secure cable into panel. See figure 4 below.
2. Connect DCS wiring to remote alarm dry contacts as requested to provide alarm signal.

4. Plug the NT25-P18 into the RIA10-1-SAA panel.
OPTIONAL: If your condensing appliance has an auxiliary interlock for normally closed
contacts, you may connect the two white lead wires from the NT25-P18 to the interlock
terminals on your appliance. The contacts will open if the water level rises too high in the
NT25-P18 which will prevent an overflow if the pump is not working.
