How to Replace a Salamander RSP75 (UK)
Fit a Salamander RSP75 pump on a UK heating or boosted DHW system. Face-to-face, orientation, bleed sequence.
Salamander
The pump
Salamander RSP75 — confirm 130 mm or 180 mm face-to-face, and whether your system is single-phase 230 V or low-voltage.
Isolate
Turn off the boiler and 230 V spur. Close both pump gate valves. Have a shallow tray ready — approx 500 mL will spill.
Fit
Undo the pump unions, transfer the power lead terminating L/N/E in the correct order into the Salamander RSP75 terminal box. Orient the pump head so the shaft is horizontal. Open valves, bleed via the centre screw until water flows clear.
Set the Salamander RSP75 to the correct speed or auto-adapt curve per the OEM installer sheet.
