Before beginning the installation, you must confirm the following site conditions:

Water Pressure Check: The recommended operating pressure for non-electric block salt softeners ranges between If your pressure exceeds ), you must install a pressure limiting valve. Low pressure can prevent proper regeneration cycles.

Main Water Entry Point: Identify the rising main stopcock. The softener should ideally be installed as close to this point as possible.

Physical Space and Level Ground: Softeners must always be installed on firm, flat, and level ground with adequate access for adding block salt and performing future maintenance.

Local Water Bylaws: All plumbing works must adhere to local water supply regulations and WRAS guidelines.

Access to Drainage and Overflow: You will need a suitable upstand or an outside drain nearby, featuring a proper air gap to prevent back-syphonage. 🛠 Step-by-Step Installation Process harvey hv3 water softener installation manual

Follow these sequential steps to safely plumb your Harvey system: 1. Isolate the Water Supply Shut off the main water supply at the rising stopcock.

Open the lowest taps in your property to drain any remaining water from the pipes. 2. Install the Bypass Valve Set A standard

fitting kit with an integrated non-return valve is required. Cut the main pipe after the stopcock.

Plumb the bypass set consisting of three separate valves: the inlet valve, outlet valve, and bypass valve.

Position the valves so that the softener inlet and outlet are closed, and the bypass valve is open. This allows the main water to resume flowing into the house while you work. 3. Route Hard Water Taps (Optional)

If your local bylaws require a separate hard water line for kitchen drinking water, or if you prefer an untreated line for the garden hose, split the line before it enters the water softener's inlet. 4. Connect the Flexible Hoses

Locate the directional arrows embossed on the back or side of the softener casing indicating "Inlet" and "Outlet". The Harvey HV3 water softener installation manual dedicates

Use standard flexible braided steel or heavy plastic hoses with the included washers.

Connect the straight end of the hoses to your plumbing bypass valves and the angled ends to the softener unit. Ensure there are no sharp kinks or tight bends. 5. Hook Up the Drain and Overflow

Drain Line: Push the flexible plastic drain hose into the quick-fit center drain connection. Route this line to your upstand or outside drain. ⚠️ Critical: Ensure a minimum

air gap at the drain line's end to avoid cross-contamination. Never shove the line directly into soil or standing water.

Overflow Line: Cut a piece of hose for the overflow connection (usually located at the rear or side of the cabinet). This must be run downhill without any kinks through an outside wall. 6. Smart Setup (The myHarvey App)

Modern Harvey units come with an i-Lid sensor system to monitor your salt levels remotely. Download the myHarvey app on your mobile device.

Pull the red battery tab to activate the sensor and hold down the sync button until the blue light flashes to pair with your local WiFi. 🚀 Commissioning and Testing

Once the installation is physically completed, you must commission the system:

Slowly Open Valves: Slowly open the inlet and outlet valves and close the bypass valve. Check carefully for any weeping or leaks around the hoses and bypass block.

Manual Regeneration: Insert a flat-head screwdriver into the manual override button located under the cover. Press and slowly turn it clockwise by one full circle until it pops back up. Let the unit drain for Add Salt and Water: Put

of water into the cabinet for the initial operation, and load the unit with your Harvey block salt.

Note: It may take anywhere from a few days to a week for the completely soft water to completely displace the residual hard water resting in your home's thermal hot water tanks.
