4.2 Plumbing Connections

Connect the water heater to your plumbing system.

1. Install a temperature and pressure relief (T&P) valve into the designated opening on the water heater. The T&P valve port uses a 3/4" NPT thread.
2. Run a discharge pipe from the T&P valve to an open drain, ensuring it is sloped for proper drainage and free of obstructions.
3. Connect the cold water supply line to the inlet port and the hot water outlet line to the outlet port. Both water ports use 1/2" NPT threads.
4. Open the cold water supply valve and allow the tank to fill completely. Open a hot water faucet in your home to purge air from the system until water flows steadily.
5. Inspect all connections for leaks.

4.3 Electrical Connection

The water heater operates on 120 Volts AC and draws approximately 12 Amps (2000 Watts).

1. Ensure the power supply circuit is rated for at least 15 Amps and is properly grounded.
2. Plug the water heater's 3-prong power cord into a dedicated 120V grounded electrical outlet.
3. Do not apply power until the tank is completely filled with water.

4.4 Temperature Setting

The thermostat on this model requires a screwdriver for adjustment.

1. Ensure power is disconnected before attempting to adjust the thermostat.
2. Locate and remove the metal cover on the unit to access the thermostat.
3. Adjust the thermostat to your desired temperature. A setting around 107°F (42°C) is often suitable for point-of-use applications.
4. Replace the metal cover securely before restoring power.

5. Operation

Once installed and filled with water, the water heater will begin heating automatically when power is supplied.

• After initial power-up, allow sufficient time for the water to reach the set temperature.
• The unit will maintain the water temperature automatically.
• Hot water will be available at the connected faucet.

6. Maintenance

Regular maintenance ensures optimal performance and extends the life of your water heater.

6.1 Draining the Tank

This model features a drain valve, which is useful for draining the tank, especially in cold climates to prevent freezing if the unit is to be shut down for an extended period.

1. Disconnect power to the water heater.
2. Close the cold water supply valve to the unit.
3. Open a hot water faucet in your home to relieve pressure and allow air into the system.
4. Connect a hose to the drain valve located at the bottom of the water heater and direct it to a suitable drain.
5. Open the drain valve and allow the tank to empty completely.
6. Once drained, close the drain valve and the hot water faucet.

6.2 Flushing the Tank

While larger water heaters benefit from regular flushing to remove sediment, smaller point-of-use tanks typically experience less sediment buildup due to constant water circulation. However, if you notice reduced hot water output or unusual noises, flushing may be beneficial. Follow the draining procedure (Section 6.1) and then briefly open the cold water supply valve with the drain valve open to flush out any potential sediment before refilling.

6.3 T&P Valve Inspection

Periodically inspect the temperature and pressure relief (T&P) valve and its discharge pipe for any signs of leakage or corrosion. Test the T&P valve annually by lifting the lever briefly to ensure it operates freely and water flows from the discharge pipe.
