Property Damage Hazard
CAUTION
Do not insert the power cord into the electrical receptacle until
all the following steps have been completed.
1. Make sure the drain valve is closed.
2. Open all hot water faucets served by the system to allow
air to escape from the tank.
3. Open the cold water inlet valve.
Note: When filling, avoid water leakage. Do not allow the
insulation of the water heater to get wet as water can reduce
the effectiveness of the insulation.
4. When an uninterrupted stream of water, without apparent
air bubbles, flows from the open hot water faucets, the
tank is full.
5. Close the hot water faucets 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.
7. Open the drain valve and let water run to flush out
any foreign matter that may have entered the system.
Continue flushing until clean water flows.
8. Close the drain valve, disconnect the hose, ensure the
drain valve does not drip and re-fill the tank.
