Here at Haws we are frequently asked if there are any periodic maintenance tips that we can offer for installed products. All Emergency Equipment is required to be activated weekly by ANSI. Purging the standing water out of the lines reduces buildup of stagnate water and helps remove rust from pipes in galvanized units. In addition, purging helps guarantee that the water supply has not been inadvertently turned off, that there are not any missing or broken parts and most importantly that the units are working properly. Eyewash maintenance is especially important. In most units there is a SP509 inline screen strainer between the eyewash valve and bowl that must be periodically cleaned. The strainer cap must be removed by a 3/8” hex wrench and the screen can then be accessed and cleaned. During the weekly testing it is also crucial to check pathways leading to the unit to make sure there are not any obstructions that would hinder the access and use of the unit. Drinking Fountains from 2003 to now have a front access 5874 push button valve which has a screen strainer under the cartridge that should be periodically cleaned depending on site conditions. In order to clean the strainer, water must be shut off to the unit and using the spanner wrench that comes with the unit, remove the push button, the inside ring nut and cartridge. The gasket screen should come out with the cartridge and should be cleaned thoroughly. Water coolers also need periodic cleaning. The fan blows air over the condenser fins, so the condenser should be vacuumed every 6 months to remove lint and dust that builds up (cleaning may be need to occur more often if the unit is in a dirty environment). This is crucial to the proper functioning of the unit, because lint and dirt buildup causes the unit to overheat due to the restricted air flow. This overheating can lead to shortening the life of the unit, and even to damaging the compressor. For all products it is important to rinse and wipe off the unit regularly to prevent dirt build-up that could potentially hinder the effectiveness of the unit.
