2. Safety Information

Please read and understand all safety instructions before installing, operating, or performing maintenance on the pressure tank. Failure to follow these instructions could result in serious injury or property damage.

• Pressure Hazard: This tank operates under pressure. Always depressurize the system before attempting any installation, maintenance, or repair.
• Professional Installation: Installation should be performed by a qualified professional in accordance with local plumbing and electrical codes.
• Proper Support: Ensure the tank is installed on a stable, level surface capable of supporting its weight when full.
• Temperature Limits: Do not expose the tank to freezing temperatures or excessive heat.
• Over-pressurization: Do not exceed the maximum working pressure of 100 PSI. Install a pressure relief valve if necessary.
• Eye Protection: Always wear appropriate eye protection when working with pressurized systems.

3. Setup and Installation

Proper installation is crucial for the efficient and safe operation of your BurCam pressure tank. This tank is designed for free-standing installation.

3.1 Pre-Installation Check:

• Inspect the tank for any shipping damage.
• Verify the pre-charge pressure of the tank using a reliable pressure gauge. The factory pre-charge is typically set to 18 PSI for a 20/40 pressure switch setting or 28 PSI for a 30/50 setting. Adjust if necessary to match your pump's cut-in pressure.
• Ensure the installation location is dry, well-ventilated, and protected from freezing.

3.2 Installation Steps:

1. Prepare the System: Turn off the power to your well pump and drain the entire water system to relieve pressure.
2. Position the Tank: Place the pressure tank on a firm, level surface. The tank is free-standing and does not require additional mounting.
3. Connect Plumbing: Connect the 1-inch MNPT connection of the tank to your water system's plumbing. Use appropriate thread sealant (e.g., PTFE tape or pipe dope) to ensure a watertight seal. Avoid overtightening.
4. Install Accessories (if applicable): Install any necessary pressure gauges, pressure switches, or relief valves according to your system design and local codes.
5. Fill the System: Slowly open the main water supply valve to allow water to fill the system and the pressure tank. Bleed air from the system as it fills.
6. Check for Leaks: Once the system is full, carefully inspect all connections for leaks.
7. Restore Power: Turn on the power to your well pump. The pump should cycle on and off as the system reaches its cut-out pressure.

4. Operation

Once properly installed, the BurCam pressure tank operates automatically as part of your water system. It stores pressurized water, reducing pump cycling and extending pump life.

Normal Operation:

• When water is drawn from the system, the pressure in the tank drops.
• Once the pressure reaches the pump's cut-in setting, the pump activates to refill the tank and system.
• When the system pressure reaches the pump's cut-out setting, the pump deactivates.
• The tank's diaphragm separates the air charge from the water, ensuring no air/water contact and preventing water logging.

5. Maintenance

Regular maintenance helps ensure the longevity and optimal performance of your pressure tank.

Annual Air Charge Check:

1. Turn off the power to the well pump.
2. Open a faucet in your home to completely drain the water system and depressurize the tank.
3. Remove the cap from the air valve (similar to a tire valve) on top of the tank.
4. Use a tire pressure gauge to check the air pressure. It should match the pump's cut-in pressure (e.g., 18 PSI for a 20/40 switch).
5. If the pressure is low, add air using a bicycle pump or air compressor until the correct pressure is reached. Do not over-pressurize.
6. Replace the air valve cap.
7. Close the faucet, and restore power to the well pump.

Note: The bladder inside the tank is replaceable. If the tank consistently loses air pressure or becomes waterlogged despite proper air charge, the bladder may need replacement. Consult a qualified technician for bladder replacement.
