• 【Solve RV Freezing Plumbing Troubles】 Custom-made for RV fresh, gray & black holding tanks, it stops tanks from freezing and supports normal water system use. 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). Simply activate the pad before freezing weather arrives, no frequent manual switching required. It maintains safe tank fluid temperature and avoids overheating damage.
• 【Application & Easy Installation】 2-Wires Design without plug for fixed place installation. Just wire this pad to a 13.5Volt DC power supply and RV power switch. If your RV does not have a dedicated negative wire, consult a qualified RV technician for proper grounding options. For best adhesion, install when ambient temperature is above 68°F (20°C).
• 【CAUTION】
-
The model CW-T1218 requires 12V DC to operate. Connect to a 12V DC circuit only. Not for 120V AC household outlets.
-
Do not install the heater pad on a circuit with a Pump Motor or Microwave Oven.
-
This product is designed and tested for use as a heating device for RV holding tank systems constructed of electrically non-conductive materials.
-
Do not activate the pad if no water in the tank, as this may cause overheating and damage the heating elements.
• 【Operating Instructions】
-
Ensure that the holding tank contains fluid before activating the pad. Fluid must cover the full surface where heater pad attaches.
-
Simply leave the switch ON during freezing weather; the built-in thermostat will handle automatic activation at 45°F and shutoff at 68°F.
-
Turn off the switch when no water in the tank or temperatures rise above freezing, or RV is not in use.
-
Ambient temperatures must be at freezing or below and remain in this temperature range while the heater pad is activated. Operation in warmer temperatures could damage your system.
