[. . . ] ­ For low temperatures, increase the flow rate or mix in cold water. 1. 3 Hot water output Type MTH 350 Output 3. 5 kW hot water output* 2. 0 l/min * The built-in automatic flow regulation provides for a constant flow rate. Hot water output with 230 V mains voltage and a temperature increase of 25 K. 1. 3 Important notes In the case of temperature selection, water temperatures of over 60 °C can be reached at the hot water outlet. Small children should therefore be kept away from the hot water outlets. · If the water feed of the MTH has been interrupted ­ e. g. [. . . ] For optimum jet patterns use only the jet regulator supplied. 13 English MTH 350 For the qualified installer 2. 6 Regulations and provisions · Installation (water and electrical installation), as well as the first start-up and maintenance of this unit, may only be carried out by a qualified installer in accordance with these instructions. · Faultless operation and operational safety are only guaranteed if the original accessories and spare parts intended for the unit are used. · In accordance with IEE and WRC Regulations. · Regulations of the local energy supply company. · Regulations of the relevant water supply company. The following should also be observed: · The unit rating plate. The specific electrical resistance of the water must not be lower than specified on the rating plate. In the case of a water grid supply network, the lowest electrical resistance of the water is to be taken into account (see Table 2). Your water supply company will advise you of the specific electrical resistance or the electrical conductivity of the water. Water installation: · A safety valve is not necessary. · Operating the unit with preheated water is not permitted!· Fittings for pressurised units are not permitted!Electrical installation: · It must be possible to isolate the unit from the main supply on all poles with an isolating distance of at least 3 mm, for example using fuses. 2. 7 Technical data (the data on the unit identification plate are applicable) MTH 350 3. 5 kW 230 V ~ 15 A 2. 0 l/min 2. 0 l/min 0. 9 l/min 2. 2 l/min 0. 05 MPa 25 °C 0. 1 l open 1. 4 kg 1 IP 25 See unit identification plate PA-No. for Germany) G 3/8, surface installation 1/N/PE ~ 230 V Bare-wire Low-lime and limy water See Table 2 Type Rated power Rated voltage Rated current Hot water output = 25 K Flow rate , , on" Flow rate , , off" Automatic flow regulation Pressure drop (during switch-on flow) Max. inlet temperature Rated capacity Design Weight Protection class in accordance with EN 60335 Protection mode in accordance with EN 60529 Test mark Structural inspection test certificate Water connections (external thread) Electrical connection Heating system Area of use Range of use with regard to specific electrical resistance / conductivity Table 1 14 For the qualified installer Areas of application for instantaneous water heaters relative to the specific electrical conductivity / specific electrical resistance of the water Designation as Areas of application for different water analysis reference temperatures* designation Standard at at at 15 °C 20 °C 25 °C 1100, 9 cm 1970 cm 1900 cm 1190. 9 mS/m 1909, 9 µS/cm 1103 mS/m 1030 µS/cm 1111 mS/m 1110 µS/cm Specific electrical resistance corresponding to specific electrical conductivity Table 2 2. 8 Installation location The MTH is to be installed, according to choice, as an over-sink or under-sink unit , in a closed, frost-free room in the vicinity of the water tap (dismantled unit is to be stored in a frost-free place, as residual water always remains in the unit). 2. 9 Unit installation Under-sink installation with AHu 40 MTH or AHEu 40 MTH fitting Loosen cover securing screws by two turns. Using a screwdriver, release the snap closing catch. Take off the unit front cover with heating block. With the help of a pair of nippers, break out the feed-through opening for the connection cable (break-off point). Fix the unit rear panel to the wall using dowels and screws; use the unit rear panel as a drilling template. Screw connecting hoses of the AHu 40 MTH or AHEu 40 MTH unit onto the water connections (1 and 2) (see fittings description), when doing this use a 14 mm spanner on the unit as a counter-force. Over-sink installation with AHo 40 MTH fitting The cold water pipe and AHo 40 MTH wall fitting must be safely secured. Screw the AHo 40 MTH wall fitting into the wall disc.
