• Mount 4 screws with washers for secure installation

Connection Notes:

⚠️ All electrical work must comply with BS 7671 (IET Wiring Regulations).

⚠️ Spa electrical installations in the UK require Part P certification.

⚠️ For units in commercial or multi-dwelling installations, a clearly labelled emergency switch must be installed at least 1.52 m (5 ft) away, adjacent to, and within sight of the unit.

⚠️ All unused in.link connectors must be plugged with blank plugs to maintain IPx5 rating.

🔍 Troubleshooting & Error Codes

Common Error Codes:

Code	Meaning	Possible Cause
Prr	Probe regulation error	Problem with regulation temperature probe
FLO	Flow error	Insufficient water flow, blocked filter, closed valves
OH	Overheat	Water temperature at heater has reached 119°F (48°C)
