Please note and ensure the following before commencing any
installation...
1. The electrical installation of this device must only be undertaken by a suitably trained and
qualified electrician; all local safety standards must be observed.
To comply with safety regulations it is necessary to have a means of full disconnection of the
iBoost+ from the supply after installation, it is recommended the installation incorporates a
double pole isolation switch in the incoming supply.
All work must satisfy Building/IEE Wiring regulations in force at the time.
2. Solar iBoost+ is designed for heating water tanks in a domestic setting with up to two
immersion heaters rated up to 3kW each which MUST include a working mechanical
thermostat.
3. There should be NO electronic controls or switches between the Solar iBoost+ and the
immersion heater, only direct connection to the immersion and mechanical thermostat are
suitable for Solar iBoost+. It is therefore recommended that the Solar iBoost+ be located at
the water tank (assuming this not within a safety zone of a bathroom which may prohibit the
fitting of electrical devices). Cable lengths between the Solar iBoost+ and the immersion
heater should not exceed 3 metres.
4. If the installation can not be effected at the water tank and cable lengths between the Solar
iBoost+ and the immersion exceed 3
installed.
5. If the existing cable to the immersion heater appears to be aged or damaged in any way,
replace the cable.
6. The Output of the Solar iBoost+ is a specially modulated DC output which must never be
connected to the normal AC circuit. The Solar iBoost+ output must be the only supply to the
immersion heaters and connected through a good quality, working mechanical thermostat.
Failure to comply will damage the unit and invalidate the warranty.
