WORK SAFE, READ THIS
Failure to read and comply with all warnings, cautions and instructions
prior to starting installation may cause personal injury and/or property damage
and void warranty.
Remove electrical shock hazard – DISCONNECT THE POWER BEFORE
INSTALLATION to avoid electrical shock and/or equipment damage. Do not use on
circuits exceeding 24 volts to avoid damage to switch, shock or re hazard.
NOTICENOTICE
In any installation where property damage and/or personal injury
might result from an inoperative switch, a back-up system(s) and/or alarm should
be installed.
NOTICENOTICE
The AquaGuard Drain pans and sensors must only be installed by a
licensed contractor or under the direct supervision of one. Condensation pan must
be properly maintained after installation and be kept free from foreign objects,
rust or other obstructions that might interfere with the proper operation of the
AquaGuard sensor. AG-4200E sensor/drain installation for Titan, Goliath and Goliath
Furnace drain pans.
STOP/READ
This device must be installed in accordance with manufacturer’s
instructions. This unit must be in accordance with all applicable local plumbing,
drainage and electrical codes.

STANDARD WIRING DIAGRAM
FOR BREAKING “WALL THERMOSTAT” POWER WIRE
1. In HVAC Unit locate HVAC Power wire going to “Wall Thermostat”, (Typically RED).
Break/Disconnect 24VAC Power wire going to “Wall Thermostat”.
A. Connect “RED”, “Input 24VAC (Hot)” and “Gray” “Common” wire of AG-1250E to 24VAC (Hot)
secondary side of 24VAC Transformer.
B. Connect “Purple”, “Normally Closed” wire of AG-1250E to Thermostat’s “R” Terminal wire.
NOTE: “Purple” wire must be connected to “Thermostat”. Maximum capacity 24VAC/5Amp.
C. Connect “BLACK”, “Input: 24VAC (Common)” wire of AG-1250E to 24VAC (COMMON) secondary
side of 24VAC Transformer or Thermostat’s “C”Terminal.
D. Optional: Connect “WHITE”, “Normally Open” wire of AG-1250E to the “WHITE” wire of
AquaGuard, AG-9100 External Alarm or Home Alarm System, or Communicating System, etc...
If not used, wire nut and tape.
NOTE: “WHITE”, “Normally Open” wire maximum capacity, 24VAC/1Amp.
2. Test the AG-1250E Secondary Pan Sensor (At start-up check initial amperage load) while the HVAC
unit is on and functioning correctly. See installation sensor.
NOTE: When AG-1250E is wired correctly, the HVAC unit will shut off upon condensate detection.

FOR CONNECTING TO SENSOR PORT
(A) NORMALLY CLOSED SIGNAL
1. In HVAC Unit locate Compressor wire going to “Wall Thermostat”, (Typically YELLOW).
Break/Disconnect Compressor wire going to “Wall Thermostat”.
A. Connect typically “YELLOW” wire, going to “Wall Thermostat” to “Gray” “Common” wires of
AG-1250E.
B. Connect “Purple”, “Normally Closed” wire of AG-1250E to Compressor’s typically “YELLOW”
wire going to compressor.
NOTE: “Purple” wire must be connected to Compressor “YELLOW” wire. Maximum capacity
24VAC/5Amp.
C. Connect “RED”, “Input: 24VAC (HOT)” wire of AG-1250E to 24VAC (HOT) of 2 VAC Transformer or
Thermostat’s “R”Terminal.
D. Connect “BLACK”, “Input: 24VAC (Common) wire of AG-1250E to 24VAC (Common) secondary
side of 24VAC Transformer or Thermostat’s “C” terminal.
E. Optional: Connect “WHITE”, “Normally Open” wire of AG-1250E to the “WHITE” wire of
AquaGuard, AG-9100 External Alarm (see Figure 1.) or Home Alarm System, or Communicating
System, etc... If not used, wire nut and tape.
NOTE: “WHITE”, “Normally Open” wire maximum capacity, 24VAC/1Amp.
2. Test the AG-1250E Secondary Pan Sensor (At start-up check initial amperage load) while the HVAC
unit is on and functioning correctly. See installation sensor.
NOTE: When the AG-1250E is wired correctly, (ONLY) the Compressor unit will shut-off upon
condensate detection. Air Handler will continue to run.
