KEY TO SYMBOLS AND SAFETY INSTRUCTIONS
1 KEY TO SYMBOLS AND SAFETY INSTRUCTIONS
1.1 EXPLANATION OF SYMBOLSWARNING SYMBOLS
Single words indicate the seriousness of the hazard in terms of the consequences of not following the safety instructions.
• NOTE indicates possible damage to property or equipment, but where there is no risk of injury.• CAUTION indicates possible injury.• WARNING indicates possible severe injury.• DANGER indicates possible risk to life.
IMPORTANT INFORMATION
The electrical diagrams show the Live, Neutral and Earth connections, between the equipment and the wiring centre as a plug and socket symbols. This is to keep the diagram clear.
Safety instructions in this document are framed and identified by a warning triangle which is printed on a grey background.
Notes contain important information in cases where there is no risk of personal injury or material losses and are identified by the symbol shown on the left. They are bordered by horizontal lines above and below the text.

2 ELECTRICAL
Greenfloor Heating can be an addition to a heating system or as a stand alone heating system.
• If the mains electrical supply to Greenfloor Heating is supplied from the heat source equipment, then it must be wired to the heat source manufacturers instructions.
• If a seperate mains electrical supply is used then it must be through either a fused double pole isolator or a fused three pin plug and unswitched socket situated, where practicable, adjacent to the wiring centre and pump & mixing station.
• The isolator must have a contact separation of 3mm minimum in both poles.
• External fuse rating 3A.
See individual products' Installation instructions for further details.
3 GENERAL INFORMATION
GENERAL GUIDANCE
This system solutions, wiring and layout guide is intended to provide an indication of the possible combinations of pump & mixing stations, controls and wiring centres available from the Greenfloor product range, but is not specific to a particular installation.
The details of an installations' specific products will be supplied within the package of information from the Worcester Design Service.
CAUTION: Isolate the mains electrical supply before starting any work and observe all relevant safety precautions.
