Hydronix RO-122-W14 3.2 Gallon Reverse Osmosis Water Storage Tank Instruction Manual

Introduction

This manual provides detailed instructions for the installation, operation, and maintenance of your Hydronix RO-122-W14 Reverse Osmosis Water Storage Tank. The RO-122-W14 is a 3.2-gallon stainless steel tank designed for reverse osmosis systems. It features a virgin polypropylene liner, a high-grade chlorobutyl diaphragm, and a 1/4" MPT water connection. The diaphragm is post-cured to ensure water remains tasteless, odorless, and contaminant-free. The tank includes a sealed brass air valve and an O-ring sealed cap for a leak-free air chamber. It is pre-pressurized and ready for use, ideal for compact RO units, RVs, campers, or other space-limited applications.

Safety Information

• Pressure Warning: This tank operates under pressure. Do not attempt to disassemble the tank or tamper with the air valve unless specifically instructed.
• Installation: Ensure all connections are secure and leak-free. Incorrect installation can lead to water damage or system malfunction.
• Water Quality: This tank is designed for use with potable water only. Do not use with non-potable water or any liquids other than water.
• Temperature: Do not expose the tank to freezing temperatures or excessive heat. Operating temperature range should be maintained as per RO system specifications.
• Maintenance: Always depressurize the tank before performing any maintenance or disconnection.
• Children and Pets: Keep the tank and associated components out of reach of children and pets.

Setup and Installation

This section outlines the general steps for installing the Hydronix RO-122-W14 storage tank into a reverse osmosis system. Always refer to your specific RO system's manual for detailed connection instructions.

Before You Begin:

• Ensure the main water supply to your RO system is turned off.
• Depressurize the existing RO system by opening the RO faucet until water stops flowing.
• Gather necessary tools: adjustable wrench, thread sealant tape (Teflon tape), and the appropriate tank connector fitting (1/4" NPT male to quick connect or compression fitting, depending on your RO system).

Installation Steps:

1. Position the Tank: Place the RO-122-W14 tank on its stand in a suitable location, typically under the sink. Ensure it is upright and stable.
2. Apply Thread Sealant: Wrap 3-5 layers of thread sealant tape (Teflon tape) clockwise around the threads of the 1/4" MPT water connection port on top of the tank.
3. Attach Tank Connector: Screw the appropriate tank connector fitting onto the tank's water connection port. Hand-tighten first, then use an adjustable wrench to tighten an additional 1/2 to 1 full turn. Do not overtighten, as this can damage the tank port.
4. Connect to RO System: Connect the outlet tubing from your RO system's auto shut-off valve (or post-filter) to the tank connector fitting. Ensure the connection is secure and leak-free according to the fitting type (e.g., push the tubing firmly into a quick-connect fitting).
5. Check Pre-charge Pressure: The tank is pre-charged. However, if you suspect low pressure, you can check it using a low-pressure gauge on the air valve (located under the blue cap). The typical pre-charge pressure is 5-7 PSI when the tank is empty. Adjust if necessary using a bicycle pump or air compressor, but avoid over-pressurizing.
6. Restore Water Supply: Slowly turn on the main water supply to your RO system.
7. Check for Leaks: Carefully inspect all connections for any signs of leaks. Tighten connections as needed.
8. Initial Fill and Flush: Allow the RO system to fill the tank completely. This may take several hours. Once full, open the RO faucet and drain the tank completely to flush out any manufacturing residues. Repeat this fill and drain cycle 2-3 times before consuming the water.

Operating Instructions

The Hydronix RO-122-W14 tank operates automatically as part of your reverse osmosis system. It stores purified water until it is needed.

• When the RO system produces purified water, it flows into the storage tank, compressing the air bladder inside.
• When you open the RO faucet, the compressed air pushes the stored water out of the tank and through the faucet.
• The tank is designed to provide a steady flow of purified water. The flow rate will decrease as the tank empties and the internal pressure drops.
• After dispensing water, the RO system will automatically begin to refill the tank.

Maintenance

Regular maintenance ensures optimal performance and longevity of your RO storage tank.

• Check Air Pressure (Annually): Over time, the air pressure in the tank's bladder can decrease. To check and adjust:
  1. Turn off the water supply to the RO system.
  2. Open the RO faucet to completely drain the tank and depressurize the system.
  3. Remove the blue cap from the air valve on the side of the tank.
  4. Use a low-pressure gauge to check the air pressure. It should be between 5-7 PSI when empty.
  5. If the pressure is low, use a bicycle pump or air compressor to add air until it reaches the recommended PSI. Do not exceed 10 PSI.
  6. Replace the blue cap.
  7. Close the RO faucet and turn on the water supply to the RO system. Allow the tank to refill.
• Inspect for Leaks: Periodically check all connections and the tank body for any signs of leaks or corrosion. Address any leaks immediately.
• Tank Replacement: The internal bladder and diaphragm can wear out over time. If you notice a significant decrease in water pressure from the RO faucet, or if the tank fills very slowly and empties quickly even after adjusting air pressure, the tank may need replacement. The typical lifespan of an RO tank is 5-10 years, depending on usage and water quality.
