73 Installation3.1 Selecting a LocationTake extra time in selecting a location since the installation location will determine the ease of theinstallation and future operation and maintenance. The location where WaterGuard is installed isdependent on various considerations:Convenient Access - WaterGuard should be installed where it can easily be viewed and operated.Dry Area – WaterGuard handles electricity and includes electronic circuitry that is susceptible to short-circuiting and/or corrosion when exposed to water or high ambient moisture levels.Away from Chemicals - Many water treatment chemicals can be corrosive to WaterGuard’s electroniccircuitry. It is highly recommended that WaterGuard is not installed adjacent to the chemicals storagearea or the dosing systems themselves.Minimum Distance from Supply Pipe - The water sampling line that is connected to the main pipe,feeding the WaterGuard should be as short as possible. A long sample line from the main pipe toWaterGuard creates an unnecessary delay between supply, measurement, analysis, and chemicaldosing.Freezing Temperatures – The analyzer should be installed in a location that is not susceptible tofreezing temperatures. The reagents will freeze, preventing accurate readings (even when thawed) andparts may be damaged due to expansion when ice forms.3.2 Site Requirements and InstallationThe WaterGuard assembly is wall mounted. It should be located on a wall where operators and servicetechnicians can easily access it for normal operation and maintenance. It is also advisable to install itwhere the operators can easily view the readings and alarms. Finally, the unit weighs approximately 6 lbs.(3 kg), so, it must be mounted securely onto a stable wall. The WaterGuard unit measures 26.3” x 13.1”(66.8 cm x 33.2 cm). The base of the complete WaterGuard assembly should be mounted at least 24” (60cm) above the floor (preferably at eye level).The WaterGuard unit and its mounting panel are not shipped with mounting screws or anchors. Theinstaller must provide screws and anchors that can hold the weight of the WaterGuard unit, mountingpanel, intake filter, and electrical outlets and junction boxes. The screws and anchors must be compatiblewith the wall where it will be installed.3.2.1 Mechanical Installation1) WaterGuard is shipped pre-mounted on a mounting panel, along with a water filter. The mountingpanel includes four screw holes, one in each corner.2) Determine the location of one hole on the WaterGuard unit or on the mounting panel.3) Secure one corner of the WaterGuard unit or mounting panel to the wall.4) Level the WaterGuard unit or mounting panel and mark the remaining three (3) screw holes.5) Secure the remaining corners to the wall using 5/16” (8 mm) screws.
