MATTER HAS BEEN CAREFULLY CONSIDERED AND ADEQUATE DUCTING AND VENTILATION HAS BEEN PROVIDED FOR THE UNIT (THE DHW ASHP) AND THAT THE OPEN FLUED APPLIANCE IS FULLY CATERED FOR IN TERMS OF SUITABLE AIR SUPPLY. Please be sure to use appropriate lifting equipment when moving the unit. 3.0 SITING THE UNIT The unit is designed to be wall mounted. -
Page 9: Heat Source
3.1 Heat Source The Ecocent can receive ducted waste heat from another area in the building – duct work can be fixed to the top of the unit and may be up to 8m long without an additional in-line fan in the ductwork being needed. The Ecocent can also draw heat from the room in which it is sited. -
Page 10: Dehumidification
Picture 1 3.2 Dehumidification – The Ecocent can be used to dehumidify rooms that are hot and damp – e.g. Laundry room (See Picture 2). The unit is equipped with a condensate drain that must be properly directed to a suitable waste pipe where the condensate water (non acidic) can drain away. -

area to prevent the formation of condensate. All ducting should be 150mm or split into two 75-80mm ducts. Picture 3 3.4 Siting Guidance 1. Decide upon the right route to be taken to move the unit in to the chosen position. - Page 12 When servicing the unit, ducting should be checked to make sure that it is clear and obstructions removed. 4.2 Water Supply Bear in mind that the mains water supply to the property will be supplying both the hot and cold water requirements simultaneously. Therefore, it is important that the maximum water demand be assessed and the water supply checked to ensure that it can meet peak demand.
- Page 13 If installing the unit in unvented configuration, an “unvented Pack”, containing the required safety valves must be supplied with the unit and there is likely to be an additional cost for this. 4.3 Outlet Fittings The unit can be used in conjunction with most types of terminal fittings. It is helpful in many mixer showers to have balanced hot and cold water supplies;...

7.2 Standing Heat Losses The amount of heat that the Ecocent loses through convection to the surrounding area (standing heat loss) is dependent on a number of things including, for example, the target temperature and the ambient air temperature surrounding the unit. The target temperature is an end user choice and the ambient temperature will depend on location;... - Page 19 But, because the Ecocent unit uses waste heat, the expected recovery times are likely to be much shorter and the following table is indicative of more normal recovery times: Volume Time 24 mins 36 mins 48 mins 72 mins 97 mins 157mins In fact, the recovery times could well be even better than this because the air source will probably warmer than used to calculate the above tables.

- Page 21 8.0 FUNCTIONS Heating Capacity The unit absorbs energy from the air taken in through the inlet ductwork. If the air inlet temperature is low, heating capacity will show a variation from standard conditions. 3 Minutes Protection When the unit stops, if you try to immediately restart the unit or turn on the manual switch, the unit will not run for 3 minutes.

A 22mm cold water supply is recommended, however, if a 15mm (1/2”) supply exists which provides sufficient flow it may be used. More flow noise may be experienced from small bore pipes due to the increased water velocity through them. The Cold Water should be fitted with a full flow isolation valve which will enable the unit to be isolated from the mains supply for maintenance or servicing. -

than the nominal outlet size of the safety device, between 18 and 27m at least 3 sizes larger, and so on. Bends must be taken into account in calculating the flow resistance. Refer to Diagram 7 and Table 1 below. An alternative approach for sizing discharge pipes would be to follow BS6700:1987 Specification for design, installation, testing and maintenance of services supplying water for domestic use within buildings and their curtilages, Appendix E,... - Page 25 Examples of acceptable discharge arrangements are: i. ideally below a fixed grating and above the water seal in a trapped gully. ii. downward discharges at low level; i.e. up to 100mm above external surfaces such as car parks, hard standings, grassed areas etc. are acceptable providing that where children may play or otherwise come into contact with discharges a wire cage or similar guard is positioned to prevent contact, whilst maintaining visibility.
- Page 26 iv. where a single pipe serves a number of discharges, such as in blocks of flats, the number served should be limited to not more than 6 systems so that any installation discharging can be traced reasonably easily. The single common discharge pipe should be at least one pipe size larger than the largest individual discharge pipe (D2) to be connected.
- Page 27 11.0 Hydraulic Connection Please bear the following points in mind when connecting the water pipes: The inner surface of all pipes should be clean, with no oxidization or dirt to restrict flow. After connecting pipes, please check the whole system for leaks before applying insulation.

It is recommended that maintenance is carried out every 12 months on the cylinder and includes the checks detailed in this manual. - Page 36 warranty/guarantee and the stainless steel cylinder may be seriously damaged. In hard water areas consideration should be given to periodically descaling the immersion heater elements. To do this the unit will need to be drained; Paragraphs 16.4 to and 16.6 below detail how to drain the unit and remove the immersion heater(s).
- Page 37 15.4 Draining the Unit Switch off the electrical supply to the unit. Turn off the mains water supply to the unit. Attach a hosepipe to the drain cock having sufficient length to take waste water to a suitable discharge point below the level of the unit, at least one metre below the unit is recommended.
