If a check valve or one-way valve is required on the cold water supply line, it is recommended that an expansion tank (100 psi, 8 gal Min.) should be installed on the hot water supply line.
When the unit is to be installed as a replacement water heater, it is important to determine whether a check valve has been installed or not.
Remove the check valve before installation of the unit unless a check valve is required by local code.
In order to prevent the water heater from being damaged or develop a leak, regardless of being used in a cold region or in a warm or hot region, the cold water supply piping, hot water supply piping, drain pipe, check valve, valves, expansion tank, and temperature and pressure relief valve should be protected with sufficient insulation materials (by wrapping with heat insulation or by equipping with a freeze prevention heater).

1. A water softener is recommended in regions where hard water may be a concern ..

2. Do not apply any heat to the unit nipples ..

3. Use standard copper alloy unions and nipples for the connections to the unit

4. Copper piping is recommended for the hot water supply line.
   Note: Refer to local codes when considering piping materials. Steel piping is not recommended as it may cause rust in the piping. Use NPT for piping of hot and cold water.

5. Connecting plumbing to the unit, hold unit fittings securely with a wrench to prevent damage to the unit.

6. Installation of a water strainer and the air release valve is recommended.

7. The distance between the water heater and places where hot water is used should be as short and direct as possible, and a uniform pipe size of sufficient diameter to carry the full capacity of hot water should be used.

8. Be sure to connect the water inlet and the hot water outlet as shown on the water heater. Reversing the two connections will damage the unit.
