WORCESTER GREENSTORE Indirect Unvented Cylinder with Solar Coil FOR USE WITH WORCESTER GREENSTORE SYSTEM HEATPUMP ONLY GB/IE WORCESTER GREENSTORE 180 CYLINDER SOLAR COMPATIBLE WORCESTER GREENSTORE 280 CYLINDER SOLAR COMPATIBLE
INTRODUCTION The Greenstore cylinder shell is made from Stainless Steel for excellent corrosion resistance. Greenstore cylinders have a strong steel case and are well insulated with environmentally friendly insulation. They are available in two sizes, 180 and 280 litres, both with a supplementary coil for use with solar or other fuels. For other fuels, you may need to source a dual thermostat for control purposes.
SCHEMATIC DIAGRAM WATER SUPPLY The Worcester Greenstore cylinder has an optimum working pressure of 3 bar (regulated by the inlet control set) and is capable of delivering upto 50 litres per minute. The maximum possible water demand should be assessed taking into consideration that both hot and cold services are supplied simultaneously from the mains. The water supply should be checked to ensure it can meet these requirements.
GENERAL INSTALLATION COLD MAINS PIPEWORK HOT WATER PIPEWORK Run the cold main through the building to where the Greenstore cylinder is to be installed. Take care not to run the cold pipe near hot water or heating pipe work to minimize heat pick up. Identify the cold water supply pipe and fit an isolating valve (not supplied) Run the first part of the hot water distribution pipework in 22mm. This can be reduced to 15mm and 10mm as appropriate for the type of tap etc.
DISCHARGE ARRANGEMENT Detailed discharge pipe installation requirement The discharge pipework must be routed in accordance with part G3 of schedule 1 of the Building Regulations The tundish should be vertical, located in the same space as the unvented hot water cylinder and be as close as possible and within 500mm of the safety device e.g. the temperature relief valve.
COMMISSIONING SERVICING SERVICING FILLING GENERAL It is important that the inner cylinder is pressurized first, followed by the primary circuit. Check the pressure in the DHW expansion vessel is 3 bar (44PSI), i.e the same as the setting of the pressure reducing valve. Servicing should only be carried out by competent installers and any spare parts used must be purchased from Worcester. Before filling, open the hot tap furthest away from the Greenstore cylinder to let air out.
