9Operating Manual geoTHERM VWS/VWW 0020051578_014.2 Requirements of the installation siteThe installation site must be dimensioned such that theheat pump can be properly installed and maintained.• Ask your heating engineer which currently applicablenational building regulations must be observed.The installation site must be dry and generally frost-proof.4.3 Accumulation of condensate(condensation water)The evaporator, the brine pumps and the pipes in theheat source circuit, as well as some components in thecoolant circuit, are insulated in the interior of the heatpump, so that no condensate can accumulate. If in theunlikely event of a small amount of condensate forming,this falls into an internal condensate pan in the bottomsection of the heat pump. As a result of the heat gener-ated inside the heat pump, the condensate in the con-densate pan evaporates. Small amounts of the accumu-lating condensate can be drained off under the heatpump. In small amounts, accumulating condensateshould not be seen as a fault in the heat pump.If an external passive cooling system is installed in yoursystem:a Caution!Danger of falling below the dew point andcondensate formation!The heating flow temperature settingmust not be too low in cooling mode. Thecooling function is still effective with aflow temperature of 20 °C.4.4 Energy saving tipsBelow you will find important tips to help you operateyour heat pump system in an energy and cost-savingmanner.4.4.1 General energy saving tipsYou can even save energy through your general actions:—Ventilate correctly:Do not leave windows or French doors tilted open.Instead, open these wide 3 to 4 times a day for15 minutes and turn down the thermostatic valvesor room thermostats while ventilating.— Do not block the radiators:this will allow the heated air in the room to circulatemore effectively.— Use a ventilation system with heat recovery:The optimum exchange of air in the building is alwaysguaranteed by using a ventilation system with heatrecovery (windows no longer need to be opened forventilation purposes). If necessary, the air flow can bematched to your individual requirements with the ven-tilation unit's remote control.— Check that windows and doors are airtight:Keep shutters and blinds closed at night, so that aslittle heat as possible is lost.— Do not cover controllers:If a VR 90 remote control unit is installed as an acces-sory, do not obstruct it with furniture, etc. as other-wise it will not be able to record the circulating roomair as effectively.— Awareness of water usage:shower instead of bath, replace seals in dripping watertaps immediately, for example.Notes on the installation and operation 4GB
