Filling the Water Heater
Do not turn "ON" the electrical supply to the water heater
until all the following steps, including “Startup” steps, have
been completed.
1. Make sure the drain valve is closed.
2. Open a hot water faucet associated with the system.
3. Open the cold water supply valve.
NOTE: When filling, avoid water leakage. Do not allow the
insulation of the water heater to get wet as water can cause
electrical malfunction.
4. When water runs out of the hot water faucet in a steady
stream, the tank is full.
5. Close the hot water faucet and check the system for
leaks. Repair as required and retest.
6. Connect a hose to the drain valve and route to a suitable
drain. Open the drain valve and let water run to flush out
any foreign matter that may have entered the system.
Once flushed, close the drain valve and disconnect hose.
Repeat steps 2-5.
