The unit has a stainless steel inner vessel, which ensures an excellent standard of corrosion resistance. The outer casing is a combination of resilient thermoplastic mouldings and plastic coated corrosion proofed steel sheet. All products are insulated with CFC free polyurethane foam to give good heat loss performance. (See Table 6, page 23)The unit is supplied complete with all the necessary safety and control devices needed to allow connection to the PremierPlus. All these components are preset and not appliance complies with the requirements of the CE marking directive and is Kiwa approved to show compliance with Building Regulations (Section G3).

4 The following instructions are offered as a guide to installation which must be carried out by a competent plumbing and electrical installer in accordance with Building Regulation G3, The Building Standards (Scotland) Regulations 1990, or The Building Regulations (Northern Ireland). NOTE: Prior to installation the unit should be stored in an upright position in an area free from excessive damp or REQUIREMENTSIMPORTANT: THIS APPLIANCE CAN BE USED BY CHILDREN AGED FROM 8 YEARS AND ABOVE AND PERSONS WITH REDUCED PHYSICAL SENSORY OR MENTAL CAPABILITIES OR LACK OF EXPERIENCE AND KNOWLEDGE IF THEY HAVE BEEN GIVEN SUPERVISORY OR INSTRUCTION CONCERNING USE OF THE APPLIANCE IN A SAFE WAY AND UNDERSTAND THE HAZARDS INVOLVED. CHILDREN SHALL NOT PLAY WITH THE APPLIANCE.

5 CLEANING AND USER MAINTENANCE SHALL NOT BE MADE BY CHILDREN WITHOUT : Do not switch on if there is a possibility that the WATER in the HEATER is THE UNITThe PremierPlus cylinder must be vertically floor mounted. Although location is not critical, the following points should be considered:The PremierPlus cylinder should be sited to ensure minimum dead leg distances, particularly to the point of most frequent siting where extreme cold temperatures will be experienced. All exposed pipe work should be insulated. The discharge pipework from the safety valves must have minimum fall of 1:200 from the unit and terminate in a safe and visible to associated controls and immersion heaters must be available to provide for the servicing and mainenance of the system.

6 Where these controls are installed against a wall a minimum distance of 250mm must be left (see Fig. 1, page 3).Ensure that the floor area for the PremierPlus cylinder is level and capable of permanently supporting the weight when full of WATER .

It is recommended that the maximum WATER demand is assessed and the WATER supply checked to ensure this demand can be satisfactorily : A high WATER PRESSURE will not always guarantee high flow possible the PremierPlus supply pipe should be 22mm.

7 We suggest the minimum supply requirements should be bar PRESSURE and 20 litres per minute flow-rate. However, at these values outlet flow rates may be poor if several outlets are used simultaneously. The higher the available PRESSURE and flow rate the better the system PremierPlus cylinder has an operating PRESSURE of bar which is controlled by the cold WATER combination valve assembly. The cold WATER combination valve assembly can be connected to a maximum PRESSURE of 16 PremierPlus cylinder is to be used for the storage of wholesum WATER (max 250mg/l Chloride ).OUTLET/TERMINAL FITTINGS (TAPS, ETC.)The PremierPlus cylinder can be used with most types of terminal fittings. It is advantageous in many mixer showers to have balanced hot and cold WATER supplies.

8 In these instances a balanced cold WATER connection should be placed between the Cold WATER Combination Valve and the PremierPlus WATER HEATER (see , page 11). Outlets situated higher than the PremierPlus cylinder will give outlet pressures lower than that at the HEATER , a 10m height difference will result in a 1 bar PRESSURE reduction at the outlet. All fittings, pipe-work and connections must have a rated PRESSURE of at least 6 bar at 80 PremierPlus cylinder should not be used in association with any of the following: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 spray type bidets or any other class 1 back syphonage risk require that a type A air gap be employed.

9 Steam heating plants unless additional and appropriate safety devices are installed. Situations where maintenance is likely to be neglected or safety devices tampered with. 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. In areas where the WATER consistently contains a high proportion of solids, suspended matter that could block the strainer unless adequate filtration can be ensured.

10 Although the primary coil PRESSURE rating is (10 bar) the 2 port zone valve supplied with the cylinder is only rated ( bar). If the cylinder is to be plumbed into a system delivering (10 bar) a suitable 2 port zone valve will have to be GENERAL PIPE FITTINGS All pipe fittings are made via 22mm compression fittings directly to the unit. The fittings are threaded 3/4 BSP male parallel should threaded pipe connections be required. COLD FEEDA 22mm cold WATER supply is recommended, however, if a 15mm (1/2 ) supply exists which provides sufficient flow, this may be used (although more flow noise may be experienced). A stopcock or servicing valve should be incorporated into the cold WATER supply to enable the PremierPlus cylinder and its associated controls to be isolated and WATER COMBINATION VALVE ASSEMBLY (FIG.)
