INTRODUCTION Thank you for purchasing your Strom-Electrical instaneous water heater, we are very proud of our products and we are sure that you will be happy with the years of service you get from your model. This product has been designed to operate at mains pressure and deliver instant hot water.

This appliance should be connected to a public mains water feed. This water heater may not be suitable for children or some elderly operators unattended due to the risk of scalding should the unit be incorrectly operated. Your Strom-Electrical water heater MUST be installed and maintained regularly by a qualified
professional in accordance with current electrical and plumbing regulations. If the chloride content exceeds 200ppm a filtration system should be fitted, failure to do so may invalidate your warrenty. This device has been designed for internal use only, if the system may be exposed to frost please drain down the system completely, and DO NOT attempt to use the device if you suspect it is frozen. Always ensure that the flow temperature is not excessive before use. If the water is too hot please increase the flow at the tap and wait for the temperature to reduce. As part of the product maintenance regularly clean the filter washer provided at the heater, failure to do so may reduce your flow rate over time. The heater is not designed for modification in any way, please do not fit anything to the unit unless otherwise recommended. When comissioning the water valve should be adjusted to increase or decrease the water flow to the unit, this in turn will control the temperature of water from the unit, slower increases the temperature, faster decreases the temperature. Each unit is tested at our factory before its departure, a little residual water is normal, and the product should be flushed through before use. Never try to operate this device if your water supply is blocked or turned off, doing so could cause premature failure of your device. Any damage to the wiring or integrity of your device should be assessed by a qualified electrician, and the device should not be used until the unit or wiring has been repaired. The minimum water supply available at the point of install is 0.02mPa. The unit must be installed in a vertical position with the connections facing downwards and should not be installed in an area with high magnetic interference. BEFORE INSTALLATION This installation must only be carried out by qualified professionals and installed to all relevent national and local electrical and plumbing regulations. Failure to do this could render the install both illegal and dangerous. Before installation please ensure the following: 1. Your Strom-Electrical appliance is intact, and the fittings are supplied & complete. 2. Please make sure the mains power supply, water pressure, earthing condition, and cabling reach the standards required for installation as required by all relevent regulations & laws. 3. The appliance must be properly earthed in accordance with all current regulations and laws. 4. If the unit is not to be used for a prolonged period of time please drain down and isolate the electrical supply of the product. 5. Position the unit upright with all plumbing connections at the bottom of the unit. 6. During the installation please test water flow is achieved at the tap before connecting the power supply. If the heater is activated without water supply the unit may be damaged. 7. This water heater may cause a small amount of water expansion due to residual heat after operation. In most systems this is easily accommodated by the distribution pipework and water supply system. In instances where problems may occur such as the existence of upstream non return valves close to the heater then it is recommended that a small shock arrestor/expansion vessel is fitted.
PRODUCT STRUCTURE WIRING SCHEMATIC SEIH9KTS1 & SEIH11KTS1 Only This diagram is provided for your reference of the internal wiring of your Strom-Electrical water heating product. No attempt should be made to change the internals of your water heater, doing so may be dangerous and will invalidate your warranty. Your product MUST always be wired by a qualified electrician in accordance with all the relevent regulations and laws in place at the time of installation.
PRODUCT MOUNTING Please remove the hanger bracket from the back of the water heater, and position on the wall in the orientation shown below. Drill three 6.00mm holes in accordance with the hanger bracket, these holes should be 100mm apart as shown below. Using wall plugs and suitably long screws secure the hanger bracket to the wall. Once the hanger bracket is installed and secure the heater unit can be mounted to the bracket. INSTALLATION Once your product has been sited in accordance with the diagrams above please connect your product to the mains water supply using a 1/2 tap hose to the blue connection of the unit, NOTE: a check valve should be fitted before your electrical water heater. Fit the supplied filter between the unit and the hose. We suggest fitting an isolation valve and ball valve before the unit to facilitate removal of the tap and servicing. Once the cold mains has been fitted you may use another 1/2 tap hose to connect your heater to the properties hot pipework circuit (this circuit could be 1 outlet or multiple outlets, please ensure your unit is capable of heating the number of outlets you are asking it to). REMEMBER: Before turning off the water supply to the unit you must isolate its electric supply, operating the unit while there is no water can cause premature failure and invalidate your warrenty. DO NOT turn on your electric supply at this time.
COMISSIONING 1. Please flush the system through completely by opening the hot tap on the water heater circuit furthest away from the heater. Allow all air, and debris to pass before closing the hot tap. 2. Turn on the power supply to the heater. 3. Using the button please turn the heater up to 45 o C. 4. When set, open as many hot outlets as likely to be used at once on the circuit, and adjust the ball valve until the temperature output at the taps matches that on the display of the unit. Increase or decrease the flow until just before the temperature drops, increasing the flow will make the target harder to achieve, decreasing the flow makes it easier to achieve. 5. This optimises the flow rate for 45 o C, if you wish to optimise for a different temperature, please set the device at the required temperature and repeat step 4. REMEMBER: Adjusting the flow to the unit up or down controls the flow at the tap which makes it easier or harder to achieve the set temperature. This may require some balancing to achieve the best results for your scenario. 6. The comissioning of your system is now complete. GENERAL USE Operation of this unit is simple: The heater automatically detects flow, so as soon as a tap is opened the heater will instantly begin to heat the flow of water in accordance with the settings provided to the heater. To control the output temperature of the heater use and buttons to set the target temperature. The LED display will show you the target temperature that has been set on the device. TOP TIP: If the unit is installed in a cupboard once the temperature has been set the cupboard can be locked, this prevents the temperature from being changed and makes the product safer for children. MAINTENANCE Always turn off the power supply before servicing your unit To ensure a long lasting and efficient product we recommend the following maintenance regime: The filter washer supplied and fitted should be cleaned to reduce any debris build up and ensure good consistent flow rates.
