2. Safety Information

WARNING: Read all instructions carefully before installation and operation. Failure to follow these instructions may result in serious injury or property damage.

• Always depressurize the system before attempting any installation, maintenance, or repair.
• Wear appropriate personal protective equipment (PPE), including safety glasses and gloves.
• Ensure all electrical connections are made by a qualified electrician and comply with local codes.
• Do not exceed the maximum working pressure specified for the tank.
• Keep children and pets away from the installation area.
• This product contains chemicals known to the State of California to cause cancer and birth defects or other reproductive harm (Proposition 65 warning).

3. Setup and Installation

3.1 Pre-Installation Checks

• Inspect the tank for any shipping damage. Do not install a damaged tank.
• Verify that the tank's pre-charge pressure matches the cut-in pressure of your well pump, typically 2 PSI below the pump's cut-in pressure. Adjust if necessary using an air pressure gauge and an air pump at the tank's air valve.
• Ensure the installation location is level, dry, protected from freezing, and has adequate space for maintenance.

3.2 Tools Required

• Pipe wrenches
• Thread sealant tape or pipe dope
• Air pressure gauge
• Air pump (bicycle pump or compressor)
• Adjustable wrench
• Bucket for draining

3.3 Installation Steps

1. Depressurize System: Turn off the power to the well pump. Open a faucet to drain water and relieve system pressure.
2. Disconnect Old Tank (if applicable): Disconnect the old pressure tank from the plumbing system.
3. Position New Tank: Place the WaterWorker HT-32B tank on a stable, level surface.
4. Connect to Plumbing: Apply thread sealant to the tank's water connection threads. Connect the tank to the main water line from the well pump. Ensure all connections are tight to prevent leaks.
5. Check Pre-charge: Re-check the tank's air pre-charge pressure. Adjust if needed.
6. Fill System: Slowly open the main water supply valve to allow water to fill the tank and plumbing system. Close all open faucets once water flows steadily.
7. Restore Power: Turn on the power to the well pump. Allow the pump to run until it reaches its cut-out pressure and shuts off.
8. Check for Leaks: Inspect all connections for leaks. Tighten as necessary.
9. Verify Operation: Open a faucet and observe the pump's cycling. The pump should not short-cycle (turn on and off rapidly).

4. Operating Instructions

The WaterWorker HT-32B tank operates automatically as part of your well water system. When the pump fills the tank, the air cushion compresses, storing water under pressure. When water is drawn from the system, the compressed air pushes the water out. The pump will only activate when the system pressure drops to the pump's cut-in setting, refilling the tank and restoring pressure.

• Normal Operation: The tank should maintain consistent water pressure throughout your home. The well pump should cycle on and off smoothly, not rapidly.
• Pressure Fluctuation: Minor pressure fluctuations are normal. Significant or rapid changes may indicate a system issue.

5. Maintenance

Regular maintenance ensures optimal performance and extends the life of your pressure tank.

5.1 Annual Air Charge Check

The air pre-charge in the tank should be checked annually, or if you notice the pump short-cycling.

1. Turn off power to the well pump.
2. Drain all water from the system by opening a faucet.
3. Remove the cap from the air valve (similar to a tire valve) on top of the tank.
4. Use an accurate air pressure gauge to check the pressure. It should be 2 PSI below the pump's cut-in pressure.
5. If the pressure is low, add air using an air pump until the correct pressure is reached. If water comes out of the air valve, the diaphragm may be ruptured, and the tank needs replacement.
6. Replace the air valve cap.
7. Restore water to the system and turn on the pump.

5.2 Leak Inspection

Periodically inspect all plumbing connections around the tank for any signs of leaks. Tighten connections as needed. Address any persistent leaks promptly.

5.3 Winterization (for unheated areas)

If the tank is located in an unheated area subject to freezing temperatures, it must be protected. Insulate the tank and surrounding pipes, or drain the system if it will be out of service for an extended period during cold weather.
