Water Supply

Bear in mind that the mains water supply to the property will be supplying both the hot and cold water requirements 
simultaneously. It is recommended that the maximum water demand be assessed and the water supply checked to ensure this 
demand can be met.
NOTE: A high mains water pressure will not always guarantee high flow rates.
Wherever possible the main supply pipe should be in 22mm. The minimum mains water supply requirements should be 
0.15 MPa (1.5 bar) working pressure and 20 litres per minute flowrate.
At these values outlet flowrates may be poor if several outlets are used simultaneously, the higher the available pressure and 
flowrate the better the system performance will be.
The Megaflo Eco SolaReady has an operating pressure of 3 bar which is controlled by the 3 Bar Pressure Reducing Valve. The 
3 Bar Pressure Reducing Valve can be connected to a maximum mains supply pressure of 1.6 MPa (16 bar). The water supply 
must be of wholesome water quality (Fluid Category 1 as defined by the Water Supply Regulations 1999).
The Megaflo Eco SolaReady is only to be used for the storage of wholesome water (max. 250mg/l chloride).

Electrical Supply

WARNING: THIS APPLIANCE MUST BE EARTHED. IT IS SUITABLE FOR A.C. SUPPLY ONLY. ELECTRICAL INSTALLATION MUST BE 
CARRIED OUT BY A COMPETENT ELECTRICIAN AND BE IN ACCORDANCE WITH THE LATEST I.E.E. WIRING REGULATIONS.
ENSURE THE ELECTRICAL SUPPLY IS SWITCHED OFF BEFORE MAKING ANY CONNECTIONS TO THE MEGAFLO ECO SOLAREADY.

The Environment

This product is made from many recyclable materials, therefore at the end of its useful life it should be disposed of at a Local 
Authority Recycling Centre in order to realise the full environmental benefits. Insulation is by means of an approved HCFC/CFC 
free polyurethane foam.
