Thank you for purchasing a Powerflow series unvented electric water heater.
The Powerflow is suitable for hand washing and dishwashing where a
number of hot outlets are required such as kitchens, schools, restaurants,
washrooms and offices. The Powerflow is the ideal solution for light
industrial, commercial and light domestic hot water requirements.
Please read and understand these instructions before commencing
installation and leave them with the user when installation is complete.
1. Important safety points
Installation must be undertaken by a competent installer of unvented water
heating systems in accordance with building regulations G3.
Building regulations G3 require a temperature and pressure relief valve to be
factory fitted. This must not be removed or blocked in any way.
Installation must comply with the latest edition of the IEE wiring regulations.
These units are very heavy. They must be securely fastened to a suitably strong
wall using the fixings supplied. Remember to allow for the weight of the water
(1kg per litre capacity) when assessing the suitability of the fixing surface.
