🛠️ INSTALLATION CONSIDERATIONS
⚠️ Professional Installation Recommended – All electrical work must be carried out by a qualified electrician according to national wiring regulations.
Electrical Requirements
- Supply Voltage: 230-240V AC, 50Hz single phase
- Current Draw: Approximately 5.2A
- Cable: 1m bare-end cable supplied (Brown = Live, Blue = Neutral, Green/Yellow = Earth for Class I)
- Isolation: Installation must include a fixed wiring switch with contact separation of at least 3mm in each pole
Mounting Position
- Suitable for horizontal mounting below hot tubs and spas
- Secure using three screws through the rubber mounting feet
- Position in a well-ventilated location – avoid cold air intake which will cause cold air injection into the spa
- Must be installed where it is not accessible without use of a tool
- Keep accessible for future inspection and maintenance
Water Protection – Critical
⚠️ Essential: The pipe or hose system must always include either:
- A double air loop AND one check valve above maximum water level, OR
- Two check valves above maximum water level
This prevents water backflow from damaging the blower.
Connection Details
- Outlet: Rotatable 1.5″ BSP union with 32mm connection (included)
- Pipe/Hose: Must be securely fixed to blower outlet
- Ensure all connections are watertight
Thermal Protection Note
If the thermal protection activates, the blower will not restart until power has been disconnected and reconnected AFTER the unit has cooled to room temperature.
Maintenance
No special maintenance required. The intake filter can be cleaned periodically by removing the two screws at the back of the blower to access the base.
