Sites claiming to provide installation instructions without the official manual often leave out critical safety warnings. For example:
If the document is not publicly listed, Harvey is legally required to provide product documentation to owners.
The manual emphasizes the importance of a bypass loop.
The Harvey HV3 is a non-electric, twin-cylinder water softener designed for installation near the main water supply, operating optimally between 1.5 and 6 bar of pressure. Installation involves connecting the unit via flexible hoses to a bypass manifold, setting up a drain with a 20mm air gap, and commissioning through manual regeneration, with salt added to the cabinet.

Harvey HV3 Water Softener Installation Guide If you’ve recently acquired a Harvey HV3 water softener and are looking for a straightforward guide to getting it up and running, you’re in the right place. The HV3 is known for its twin-tank design and non-electric operation, making it a favorite for those who want soft water without the hassle of programming buttons or managing power cords.
Below is a comprehensive walkthrough of the installation process. 1. Pre-Installation Checklist
Before you start cutting pipes, ensure you have the following essentials: The Unit: Your Harvey HV3 softener. harvey hv3 water softener installation manual free
Installation Kit: Usually includes 15mm or 22mm hoses, a bypass valve, and a drain hose. Tools: Pipe cutter, adjustable wrench, and bucket. Salt: Block salt is specifically required for the HV3. 2. Choosing the Location
The HV3 is compact enough to fit under a standard kitchen sink. However, you must ensure:
Access: You need enough room to lift the lid and slide in salt blocks. Level Ground: The unit must sit on a flat, stable surface.
Drainage: It needs to be within reach of a waste pipe or standpipe. 3. Plumbing the Bypass Set
A bypass valve is crucial. It allows you to divert water away from the softener if you ever need to perform maintenance or move the unit. Turn off the mains water supply.
Install the inlet, outlet, and bypass valves into your existing pipework. If the document is not publicly listed, Harvey
Ensure the arrows on the valves match the direction of the water flow. 4. Connecting the Hoses
The HV3 uses flexible high-pressure hoses to connect to your plumbing:
Inlet: Connect the hose from your "hard" water supply to the inlet port on the back of the softener.
Outlet: Connect the hose from the softener's outlet port back to your "soft" water internal plumbing.
Ensure Washers are Seated: Hand-tighten the nuts first, then give them a quarter-turn with a wrench to prevent leaks. 5. Managing the Drain and Overflow
This is a non-electric unit, so it relies on water pressure to regenerate. and commissioning through manual regeneration
Drain Hose: Connect the 1/2" reinforced hose to the drain outlet. Route this to a standpipe or an under-sink waste trap. Crucial: Maintain an "air gap" to prevent back-siphonage.
Overflow: Connect the smaller overflow pipe to the cabinet and route it through an outside wall. This ensures that if the unit ever malfunctions, water leaks outside rather than in your kitchen. 6. Commissioning the HV3
Slowly turn on the water: Open the inlet valve partially to allow the tanks to fill without a sudden surge of pressure. Check for leaks: Inspect every joint.
Flush the system: Run a cold tap (ideally the kitchen tap) for several minutes to clear any air pockets and resin dust.
Add Salt: Insert two blocks of Harvey salt into the front compartment. 7. Testing the Water
Once installed, use a total hardness test kit. Your water should now register as "0" or "trace" hardness. If the water remains hard, check that the bypass valve is closed and the inlet/outlet valves are fully open.
Maintenance Tip: The HV3 is "fit and forget." The only thing you need to do is keep it topped up with block salt. When you see the red indicator or the salt levels get low, simply slide in new blocks.
