Safety Information

WARNING: Read all instructions completely before installation. Only qualified personnel should install or service this equipment according to local codes and ordinances. Improper installation, adjustment, alteration, service, or maintenance can cause property damage, severe injury, or death.

WARNING: A relief valve must be installed to prevent pressure exceeding local code requirements or the product's maximum working pressure. Failure to inspect the relief valve could lead to unsafe temperature or pressure build-up, resulting in product failure, property damage, or serious injury.

WARNING: Do not exceed 80 psi (5.5 bar) air charge. Exceeding this pressure can be hazardous and will void the warranty. Failure to follow these instructions could result in property damage, injury, or death.

WARNING: This expansion tank is designed for water storage up to a maximum pressure of 150 psi (10.3 bar) and a maximum temperature of 200 °F (93 °C). Use for anything other than potable water, or at pressures exceeding 150 psi (10.3 bar) or temperatures exceeding 200 °F (93 °C), is unsafe and may cause property damage, injury, or death.

2. Installing the Expansion Tank

• Drain the water system or isolate the area where the expansion tank (A) will be installed.
• Install the expansion tank (A) on the supply side of the water heater, or on the suction side of the heating circulator. Use a hanger strap to support the weight of the expansion tank (A), if needed.
• Re-pressurize the system and check for leaks. Repair as necessary.
• Restart the water heater system and check for relief valve discharge. If the relief valve drips, the expansion tank may be improperly charged or undersized.
