Because the HV3 is non-electric, you must manually initiate regeneration to purge air and packing fines.
| Section | Feature Description | |---------|----------------------| | Unpacking | Check for HV3 control valve, brine tank, ¾" fittings, drain hose, bypass valve | | Tools required | Adjustable spanner, pipe cutter, PTFE tape, bucket, spirit level | | Mains connection | Isolate water supply, install bypass valve first, connect inlet/outlet | | Electrical | Plug into unswitched socket – controller retains settings for 24h during power loss | | Commissioning | Manual regeneration cycle to purge air and bed fines | | Programming | Set hardness level (ppm or °Clark), regeneration day override, time of day | | Test procedure | Check for leaks, verify soft water hardness (<5ppm), drain flow clarity |
The manual lists the following tools as essential: harvey hv3 water softener installation manual
Pro tip from the manual: Always install the softener downstream of the main stop tap and upstream of the water heater (except for the outside tap and kitchen drinking tap, which should remain hard).
The HV3 must be installed:
⚠️ Important: The HV3 uses water pressure to regenerate. Minimum working pressure: 1.4 bar (20 psi). Maximum: 5.5 bar (80 psi).
Understanding these specs is the first page of the installation manual. Ignoring them is the fastest way to void your warranty or cause poor performance. Because the HV3 is non-electric, you must manually
| Problem | Likely Cause | Fix | |---------|--------------|-----| | No regeneration | Low water pressure | Check pressure >1.4 bar | | Hard water leaking through | Bypass open or internal seal failure | Check bypass; call Harvey | | Water runs to drain constantly | Dirt in piston or damaged seal | Clean valve; replace seal | | Brine tank overflows | Stuck float valve | Clean or replace float assembly | | Salty taste in water | Blend valve too closed or low pressure | Open bypass slightly |
