InStallatIon29EnglishMaintaining circulating water amountf If the product is operated below minimum amountof circulating water (more than 50 % of rated flowrate), plate type heat exchanger may freeze and bedamaged. Use the product within recommendedcirculating water amount.f Maintain water level since it may decrease byblocked strainer, remaining air, malfunction ofcirculating pump.Drainage during winter timef When DVM CHILLER is not operated during wintertime, drain all water by opening drain valves inCHILLER shown in figure.Drain valveCaUtIon• Be careful that because the water inlet pipe has nodrain plug, a small amount of water may come outfrom the pipe when the coupling is disassembled.air ventingf Vent air by opening two air vent valves on inlet andmiddle of the pipe of water side heat exchanger.If air venting is not done properly, it is difficult tomaintain rated flow rate, and pipe corrosion or noiseby remaining oxygen may occur.Air vent valvef When venting air, be aware to prevent water get into the box.Solution for freeze protection deviceWhen freeze protection device is activated, plate heatexchanger may freeze. Operate the product aftertaking care of the cause. If you operate the productbefore the problem has been taken care of, plate typeheat exchanger will be frozen and damaged, causingrefrigerant leakage or water may enter into therefrigerant cycle.Solution for pump vibration noiseInstall flexible joints at inlet/outlet and use vibrationproof rubber on the pump since noise may occur whenpump vibration is transferred to pipes.Maintaining contaminationSmall foreign substances in chilled/heating water maypass through the strainers and may become stuckor stacked inside plate type heat exchanger. Foreignsubstance accumulation inside the plate type heatexchanger can lead to performance decrease or it mayfreeze and and be permanently damaged. Therefore,clean the plate type heat exchanger periodically.Turbidity is a standard for water pollution level, andstandard water pollution set by Corrosion PreventionAssociation is under turbidity 4. If the turbidity is highor foreign substance is contamination in too high, cleanthe plate type heat exchanger periodically and maintainthe turbidity under 4. If it is over 4, clean the product inabout 1 year after the initial operation of the product.notE• Refer to page 67 for water maintenance standardtable.Solution for water level decreaseWhen a tank or thermal storage is installed, selecta pump that can provide required water amountconsidering head loss pipe resistance.CaUtIon• The product should be operated for 3 minutes afterit has stopped to protect water side heat exchanger(plate type heat exchanger) from freezing.
