Titan Tankless water heater Installation instructions
- The Titan water heater is designed to be installed with pipes and accessories of copper or CPVC of 1/2 inch or 3/4 inch of diameter, depending on the model. Tighten the nuts in the inlet of cold water and the outlet of hot water without using Teflon tape. Use a 7/8” wrench so the nuts are not damaged.
- For easy of service install a shut-off valve both in the inlet and in the outlet of the unit.
- It is recommended to install a sediment filter to prolong the life of the unit and a pressure relief valve as a safety precaution.
- Secure the unit to the wall utilizing two screws vertically spaced by 6 1/2 inches.
- Allow water to circulate in the new installation to make sure there is no leaks in the installation.
- The Titan water heater comes with 2ft of 8AWG wires. If you need to extend that wire to the junction box or directly to the breaker panel, those wires should be 6AWG for the SCR-2 series (Titan N-120, Titan N-100, Titan N-85). Depending on the power of the model selected and the distance with respect to the main breaker panel you can find the specifications of the other Titan water heater models on our TECHNICAL SPECIFICATIONS table.
- To avoid an energy overload, you must install the appropriate breaker in the safety switch. The breaker should be of same or slightly bigger than the requirements for the energy consumption of the model being installed.
- Make sure the joints are rightly made and properly isolated. Do not forget to install the neutral (Ground) wire to the main breaker panel.
- Before you energize the unit, allow water to circulate during approximately 20 seconds to make sure the unit doesn’t work dry which will damage the heating elements.

IMPORTANT STEPS TO FOLLOW WHILE PERFORMING THE INSTALLATION
- Do not open the water heater when performing the installation. It's not necessary and it will void the warranty.
- If you are installing an N-120 like in the picture shown use cable 6AWG from the water heater to the breaker panel. Note: The wire size required might vary by local electric codes.
- Use rigid copper pipe (Dia. 1/2") with related accessories or CPVC (Dia. 1/2") plastic plumbing pipe.
- Refer to our Recommended Applications for the appropriate type and quantity of breakers to use. The Titan N-120 (picture shown) would use a 60Amp double pole breaker.
- Do not use Teflon tape or plastic on the threads of the inlet or outlet of the unit as it might go inside the unit and cause a malfunction.
- Do not weld the compression fittings.
- It is recommended to install a disconnect box close to the water heater for connecting and disconnecting for security and maintenance purpose.
- Never weld galvanized or copper pipes next to the water heater. At the moment of installation it is recommended to take out the water heater before welding.
- Excess solder paste use should be avoided to keep it from going inside the unit.
- Before powering the unit ON make sure there is no leak in the water pipes.
