1.GENERAL INFORMATION Read this guide before installing and operating the meter. In case of incorrect mounting ISIPARK's guarantee obligations no longer apply. Please note that the following installation conditions must be obeyed. 2.TECNICAL SPECIFICATION 2.1 Flow Sensor: The ow sensor is a device used to measure a uid-ow. Flow sensors gets signals from 2 different points. Calculator measure ow rate by using times difference between 2 signals. Because of there is no moving part in ultrasonic sensors, mechanical life of the sensor is longer than mechanical heat sensor.

3.1 Installation Requirements GUK-xx MB has been designed for indoor installation in non-condensing environments with ambient temperatures from 5~55oC. The meter must not be under any mechanical stress when installed in the pipe. The meter must be protected against pressure shocks in the pipe. The humidity of the mounting environment shall not exceed 85% (without condensation). Protection class IP65, allows short-term submergence, provided that all cable unions have been correctly mounted and that the plastic cover has been properly fastened. Make sure the meter is installed sufciently far away from possible sources of electromagnetic interference (switches, electric motors, uorescent lamps, etc.). All control cables must be drawn separately and not parallel to e.g. power cables or other cables with the risk of inducing electromagnetic interference. There must be a distance of min. 25cm between signal cables and other installations. If two or more meters are to be installed shall be in parallel, the axis-center distance between two meters shall be at least 135mm minimum. Prior to installation of the ow sensor, the pipe shall be thoroughly ushed out, and any dirty, stone alike items must be removed from the pipe. Cavitation in the system must be avoided. If a risk of frost exists, empty the system and, if necessary, remove the meter. If the water is soiled, t the strainer in the pipe before the meter.

Sufcient distance.10×DN straight pipe in upstream and 5×DN straight pipe in downstream. (DN: Diameter) Heat meters are precision devices and must be protected against impact and vibration. Store meters in a frost-free place (also during transport). The meter can be damaged by frost. Never hold and transport the meter by the calculator but only by the ow pipe. Pay attention to sharp edges like thread, etc. 3.2 Mounting of Heat Meter Consider the dimensions of the heat meter, and the distance with surroundings, minimum 3 cm free space. The meter is to be installed so that the direction of the arrow on the meter housing corresponds to the direction of ow. Avoid the collection of air bubbles in the meter during the installation process. The connecting pipe at the two ends must be on the same horizontal level. Install horizontally or vertically only, not tilted, inclined or overhead. Install the ow sensor into horizontal or up streaming pipelines. Do not install at highest point of piping to avoid air inside the ow sensor. The ow sensor must not be installed in the positions where swirling ow exists (swirling ow is normally caused by bending pipe), or pulsatile ow exists (pulsatile ow is normally caused by pump, therefore the ow sensor must be installed as far as possible from pump and must not be installed on the outlet of pump) or air may build up. 3142.5 3

3.3 Mounting of Temperature Sensors Temperature sensors used to measure the ow temperature are usually installed exfactory, i.e. integrated into the ow pipe. Installation instructions for sensor used to measure pipe and return temperature are as followings: 3.3.1 Matched Pairs The Sensors are colour-coded. The one marked with a red sign is to be installed in the ow pipe normally within the sensor pocket; the other marked with a blue sign is to be installed in the return pipe. The two temperature sensors are a matched pair and must not be separated, so the sensors must be replaced in pairs. The connecting cables may not be buckled, extended or shortened. The standard cable length according to EN1434 or OIML R75 is 1.5m and must not be changed. If the length has to be changed due to restriction of installation environment, the meter shall be specially dealt within the factory. 3.3.2 Install Position The end of the sensors must extend in any case as far as the center of the pipe crosssection. Installation of the temperature sensors should be preferably symmetrical and direct installation. Do not remove the ow sensor if already mounted in the ow sensor. Temperature sensors are to be installed in the area where water temperature is relatively stable. The installation conditions for the two sensors shall be identical. Sensors shall not be installed in the high convex segment of the pipe. Temperature sensors typically can be installed within Tee pipe, ball valve or sensor pocket. 3.3.3 Sealing Temperature sensors and screw connections must be sealed against manipulation, and the seal may not be damaged. Attach the O-ring for the installation aid, and insert the O-ring into the installation point according to with a slight circular motion. Insert the temperature sensor into the installation point and screw it in tightly until the dead stop of the seal. Secure the sensor after installation against unauthorized removal with appropriate sealing.Generally, the seals have been installed on the meter before delivery from factory.

3.4 Mounting of Calculator The calculator is mounted directly on the plate of ow sensor. Having been mounted, the calculator is sealed with seal and thread. In case of strong condensation or water temperature above 90 oC, we recommend wall mounting of the calculator. The ambient temperature of the calculator must not exceed 55oC and it should avoid direct sunlight. Mounting can be vertical or horizontal with respect to the ow sensor. The calculator can also be removed from the ow sensor, and plug it in the required position. 3.5 Installation of non-return valve The meter can be supplied with a non-return valve (if required) on request. The nonreturn valve must be installed on the water inlet end of meter when installing.

www.generallife.com.tr

3.6 After the installation The tightness must be proved by pressurizing with cold water, slowly lling the pipe on completion of the installation. Open the shut-off valves carefully and check installation for leakage. While the piping system is operating, check whether the volume display correctly and the temperatures display corresponding with the actual temperatures (see the display information). When the response thresholds are exceeded and the ow rate and temperature difference are positive, the energy and the volume are summated. Make the segment test, in order to displays all display segments for test purposes. The operating hours are counted from initial connection of the battery. The date is incremented daily. As a standard the meter is delivered with the local time, or destination time if required.
