The odors will gradually dissipate and should not be noticeable after oneweek of regular use. You may use the thermostat mode button to flush the reservoir with fresh waterto more quickly eliminate the odors.bUbbLES AND WATER CARRYOVERThe same binders that cause odors can cause bubbles to form on the surface of the DCM. The bubblesmay carry water droplets into the supply air outlet, especially when the fan is running at high speed.Frequently flushing the reservoir during the first week of operation should also cure this problem; if itpersists, contact your dealer.MOLD CONCERNSAs with all HVAC equipment there is always the consideration of mold growth. Mold growth is a realconcern in single stage evaporative “swamp coolers”. The OASys unit has been designed with severalfeatures that will prevent mold growth. If properly installed and maintained there should be no moldgrowth in the OASys unit. As part of the annual service and maintenance of the unit a visual inspectionshould be made to ensure that these features are working properly and that mold is not present in theunit.1. The Dump Cycle prevents the build-up of dirty water.2. The Dry Out Cycle avoids the moist environment conducive to mold growth.3.A biocide additive is available and should be used if the OASys is installed in a climate area thatexperiences periods of relatively high humidity.WINTERIzATIONIf you live in an area subject to freezing temperatures, at the end of the cooling season turn off watersupply to the unit and ensure that the supply connection is drained and that the unit is dry.
