Outlet / Terminal Fittings (Taps, Etc.)
The Megaflo Eco SolaReady can be used in conjunction with most types of terminal fittings. It is advantageous in many mixer
showers to have balanced hot and cold water supplies, in these instances the balanced cold water supply should be teed off
the supply to the Megaflo Eco SolaReady immediately after the Cold Water Combination Valve (See Figure 5 page 10).
A connection is provided for this purpose, if not used it should be capped off with a suitable stop end fitting. Branches to cold
drinking outlets should be taken before the valve.
Outlets situated higher than the Megaflo Eco SolaReady unit will give outlet pressures lower than that at the heater, a 10m
height difference will result in a 0.1 Mpa (1 bar) pressure reduction at the outlet fitting.
NOTE: Accessories should have a rated operating pressure of at least 0.8 MPa (8 bar).
Limitations
The Megaflo Eco SolaReady unvented water heater should not be used in any of the following instances:
• Solid fuel boilers or any other boiler in which the energy input is not under effective thermostatic control unless additional
and appropriate safety measures are installed.
• Gravity circulation primaries.
• Steam heating plant unless additional and appropriate safety devices are installed.
• Ascending spray type bidets or any other Class 5 back syphonage risk requiring that a Type AA, AB, AD or AG air gap be
employed.
• Water supplies that have either inadequate pressure or where the supply may be intermittent.
• Situations where it is not possible to safely pipe away any discharge from the safety valves.
• Areas where the water consistently contains a high proportion of solids, eg. suspended matter that could block the strainer,
unless adequate filtration can be ensured.
• The installation must be carried out in accordance with the relevant requirements of:
• The appropriate Building Regulations: either The Building Regulations (England), The Building Regulations (Scotland) or
Building Regulations (Northern Ireland).
• The Water Fittings Regulations (England and Wales) or Water Byelaws (Scotland).
