Facon 8"x25" RV Holding Tank Heater Pad with Built-in Thermostat, for Fresh/Grey/Black Water Tanks, 120V AC

• 【Solve RV Freezing Plumbing Troubles】 Custom-made for narrow rectangular RV fresh, gray & black holding tanks. Designed for RVs connected to shore power, it can be used alone or matched with pipe & elbow heater pads for full pipeline freeze protection.

• 【Smart Automatic Thermostat Control】 Built-in thermostat auto switches ON at 45°F (±5°F) and OFF at 68°F (±5°F). It automatically maintains safe tank fluid temperature and avoids overheating damage. Two wiring versions: hardwired 2-wire design with 36-inch lead wire, or ready-to-use 72-inch 2-prong plug cord for direct shore power connection.

• 【Application & Easy Installation】 Single-sided heating with built-in adhesive. Peel off backing paper and stick or wrap the pad onto the holding tank. Do not place items on top; heavy pressure will damage internal heating elements. The pad stays cool to touch during normal operation. Install at a minimum ambient temperature of 68°F (20°C).

• CW-T825: 36-inch 2-wire hardwire design, Red Wire=Positive (+); White Wire=Negative (-). Consult a qualified electrician if unfamiliar with AC wiring.

• CW-T825-P: 72-inch 2-prong power cord, directly plug into standard 120V AC outlet.

• 【CAUTION】

1. This 120V AC model only works with shore power receptacles, do not connect to 12/13.5V DC RV battery system.

2. Do not install the heater pad on a circuit with a Pump Motor or Microwave Oven.

3. This product is designed and tested for use as a heating device for RV holding tank systems constructed of electrically non-conductive materials.

4. Do not activate the pad if no fluid inside the tank, as this may cause overheating and damage.

5. Do not place any objects such as batteries on top of the heater pad.

6. Power socket recommendation: Use 15A GFI-protected 120V AC receptacle; all wiring connections must stay dry and away from liquid puddles. If an extension cord is needed, use a 15A rated outdoor-grade cord.

• 【Operating Instructions】

• Ensure that the holding tank contains fluid before activating the pad. Fluid must cover the full surface.

• Hardwire version: Flip power switch ON when temperature drops near freezing; Plug-in version: Insert the 2-prong cord into shore power outlet.

• The built-in thermostat will automatically turn ON the heater at 45°F (±5°F) and OFF at 68°F (±5°F).

• Manually cut off power / unplug the cord when outside temperature stays above freezing, fluids are fully emptied, summer arrives or RV is not in use.

• Ambient temperatures must be at freezing or below while the heater pad is activated. Operation in warmer temperatures could damage your system.
