INSTALLATION Appliance installationENGLISHwww.stiebel-eltron.co.uk ESH Trend GB | 78.4 Water supply NoteDo not use the pressure-compensated cold water connec-tion for supplying any outlets other than mixer taps and bidets. Do not use the pressure-compensated cold water connection for supplying all cold water outlets. Material lossesThe sealed unvented appliance is designed for a supply pressure of up to 0.8MPa. For pressures greater than 0.8MPa, an additional pressure reducing valve must be installed in the supply line to the appliance.We recommend an uninterrupted 22mm cold water supply. If only a 15mm supply is available, this may be used, provided the ﬂow rate is sufﬁcient. We recommend a minimum pressure of 0.25MPa and a ﬂow rate of 20l per minute with a dynamic pressure of 0.1MPa. The DHW cylinder can also be operated with lower pressures and ﬂow rates. This will however impair the performance.9. Appliance installationPreliminary wiring Note - Always use a suitable heat-resistant ﬂexible cable with a temperature resistance of at least 90°C, e.g. H05V2V2-F (309-Y). - Size the conductors in accordance with the IET Wir-ing Regulations. - For threaded immersion heaters we recommend ≥2.5mm², due to the high ambient temperatures of up to 90°C. - The entire internal wiring is ﬁtted at the factory.We recommend routing the electric wires to the terminal box prior to ﬁnal installation and ﬁtting of the pipework. The appliance features two channels in the base, for routing elec-tric cables to the DHW cylinder. The channels run diagonally from centre front to back left and back right. They allow for neat installation with minimal visible cabling.f Remove the covers of the terminal box when positioning the DHW cylinder. f Route the wiring from the base channels up into the terminal box. f When connecting the ﬂexible cable, secure it with a cable clamp. The cable clamp is included in the accessories.The ﬂexible cable must be sufﬁciently long to allow the cable to reach from the terminal box through the base channels while also leaving an adequate excess length protruding at the front of the DHW cylinder. This allows the power connection point to be reached. See chapter “Installation/ Electrical connection/ Wiring up threaded immer-sion heaters and temperature controllers”.Pipework connectionAll pipework connections are at the top of the DHW cylinder. The pipes are secured to the back panel. A template assists with plac-ing the pipes. 9.1 Positioning the appliance CAUTION InjuryThe product must be correctly aligned both vertically and horizontally. The ﬂoor or wall on which the appliance is installed must be suitable for supporting the total weight of the appliance in operation. See type plate. NoteMaintain a minimum clearance around the appliance for servicing. The minimum clearance must be no less than 400mm in front of the immersion cover / 150mm above the DHW cylinder.f Decide where the DHW cylinder is to be positioned. f Then secure the wall template with the cross on the back panel, ensuring a minimum clearance of 326mm to the left wall.f Before positioning the DHW cylinder, wind out the feet in the bottom until they protrude 10mm (35mm if using the op-tional wall mounting bracket). Refer to the template supplied to ensure the cross is positioned at the right height above the ﬂoor in relation to the relevant capacity of the DHW cylinder. f If the DHW cylinder is raised above ﬂoor level, either on its feet or on a base, the height of the template above the ﬂoor will need to be raised accordingly.When ﬁtting the connectors, ensure they protrude from the back panel horizontally, perpendicular to the wall and parallel to each other. The table below shows the precise lengths these connec-tors must be cut from the wall in order to reach the cylinder connections. - If pipes have to be routed upwards on the back panel behind the cylinder position, the connectors must be longer. Use the lengths marked ‘below’. - If the pipes are being routed from above or from the side, use the lengths marked ‘above’.Connector length from wall Top BottomCold water inlet (3) 202 242DHW outlet (1) 274 314Balanced cold water outlet (2) 188 228

Hold it in this position for 30seconds.f Check the pre-charge pressure in the expansion vessel and adjust the pressure if required.f Open the cold water supply valve.f When water ﬂows through the open hot water tap, close the tap. f Switch on the power supply to the threaded immersion heaters.12.5 Pre-charge pressure of the expansion vessel NoteThe expansion vessel requires annual servicing and may not be altered or converted. If water is discharged intermittently or slowly from the tundish during heating, the appliance needs to be serviced by a qualiﬁed contractor and the pre-charge pressure must be restored to the original value.f The expansion vessel must be fully drained in order to check the pre-charge pressure. If the pressure deviates from the value indicated on the label, it must be restored to the origi-nal value. f Never remove the expansion vessel without lowering the pressure in the DHW cylinder and draining 10-20l water via the drain valve in the bottom of the DHW cylinder.12.6 Regular maintenance work NoteIn areas with corrosive water, failure to observe the main-tenance instructions for the threaded immersion heater can cause the threaded immersion heater to separate from the DHW cylinder, with subsequent water leakage.The following maintenance work must be performed annually by a qualiﬁed contractor:f Check the temperature and pressure limiter and the expan-sion valve.f Operate each valve manually by turning the operating cap. f Check that water can ﬂow unimpeded through the tundish to the outlet point.f Make sure that the expansion valve and the temperature and pressure limiter close correctly.f Carry out a visual examination of the expansion vessel.f If the pressure is below 0.3MPa, top it up with a suitable air pressure pump until it reaches the pressure value indicated on the vessel’s label.f Remove, clean and replace the pipe strainer.

INSTALLATION MaintenanceENGLISHwww.stiebel-eltron.co.uk ESH Trend GB | 13f After 5 years, the threaded immersion heater must be re-moved for inspection as part of the maintenance. Inspect the threads for corrosion. Replace the threaded immersion heater if any signs of corrosion are found. Subsequently, the threaded immersion heater must be removed and examined every 3 years.f Carry out a visual inspection of the following parts: - Valves - External taps and ﬁttings - Threaded immersion heater - Electrical connections12.7 Replacing the combination valvef Once the combination valve has been removed from the DHW cylinder, it can be dismantled by unscrewing the separate parts. The entire combination valve can be removed from the upper connection by unscrewing it. f Do not tighten the combination valve when reﬁtting it. A double o-ring provides the seal. f To create the seal, screw the combination valve downwards until it will not go any further. Then turn it back less than one full turn, so that it points in the required direction.12.8 Removing / replacing the drain valvef Disconnect the appliance from the mains power supply at the MCB/fuse in the distribution board.f Drain the appliance. See chapter “Maintenance / Draining the appliance”.f Once the DHW cylinder is fully drained, unscrew the rear locking ring behind the drain valve. To do this, turn the lock-ing ring clockwise. f Pull off the drain valve.f To reinstall the drain valve, follow all the steps in reverse order.
