English 2/8Hyperchill-Precision Control ICE015-0572 IntroductionThese water coolers are monoblock units for the production of cooledwater in a closed circuit.The fan, pump and compressor motors are equipped with a thermalprotector that protects them against possible overheating.2.1 TransportThe packed unit must remain:a) Upright;b) Protected against atmospheric agents;c) Protected against impacts.2.2 HandlingUse a fork-lift truck suitable for the weight to be lifted, avoiding anytype of impact2.3 Inspectiona) All the units are assembled, wired, charged with refrigerant and oiland tested in the factory;b) On receiving the machine check its condition: immediately notifythe transport company in case of any damage;c) Unpack the unit as close as possible to the place of installation.2.4 Storagea) Keep the unit packed in a clean place protected from damp andbad weather.b) Do not stack the units;c) Follow the instructions given on the package.3 InstallationYFor correct installation, follow the instructions given in par.7.2, 7.3and 7.7.Y For the correct application of the warranty terms, follow theinstructions given in the start-up report, fill it in and send it back toSeller! Liquids to be chilledThe liquids to be chilled must be compatible with the materials used.Examples of liquids used are water or mixtures of water and ethyleneor propylene glycols.The liquids to be chilled must not be flammable.If the liquids to be chilled contain hazardous substances (e.g. ethylene/propylene glycol), any liquid discharged from a leakage area must becollected, because it is harmful to the environment. When drainingthe hydraulic circuit, comply with the current regulations and do notdisperse the contents in the environment.3.1 Operating spaceLeave a space of 1.5 m around the unit.Leave a space of at least 2 metres above the refrigerator in models withvertical emission of condensation air.3.2 VersionsAir-cooled versionAxial fans (A)Do not create cooling air recirculation situations.Do not obstruct the ventilation grilles.The ducting of extracted air is not recommended for versions withaxial fans.Centrifugal version (C)Always ensure a minimum counterpressure on the delivery offans, ducting the individual hot air outlets.Water- cooled version (W)If the water to the condenser is in open circuit, install a mesh filter onthe condensation water inlet.Please note that for special cooling water types such as demineral-ized, deionized or distilled it is necessary to contact the manufacturerto verify which kind of condenser should be used since the standardmaterial may not be suitable.3.3 Water circuit3.3.1 Checks and connectionY Before connecting the chiller and filling the water circuit, checkthat all the pipes are clean. If not, wash them out thoroughly.Y If the plumbing circuit is of the closed type, under pressure it isadvisable to install a safety valve set to 6 bar.Y Always install mesh filters on the water inlet and outlet pipelines.Y If the hydraulic circuit is intercepted by automatic valves, protectthe pump with an anti-hammering system.Y If the hydraulic circuit is emptied for shut-down periods werecommend that you add lubricating fluid to the pump’s impeller toavoid the risk of blockage when it is re-started. In case the impeller isblocked then you should unblock it manually.Remove the rear cover of the pump and carefully turn the plastic fan.If the impeller is stuck then remove the fan and turn the impeller shaftdirectly. After un-blocking the impeller re-assemble the fan and cover.Preliminary checks1) Check that any shut-off valves in the water circuit are open.2) In the case of a closed water circuit, check that an expansion tankof suitable capacity has been installed. See paragraph 3.3.3.Connection1) Connect the water cooler to the inlet and outlet piping, using thespecial connections located on the back of the unit.We recommend the use of flexible unions to reduce system rigidity.2) Fill the water circuit using the fitting provided on the rear of thechiller ( ).3) The tank is equipped with a breather valve that should be operatedmanually when filling the tank. Also, if the hydraulic circuit has highpoints, install a vent valve at the highest points.4) We recommend that taps are installed on the inlet and outlet pipes,so that the unit can be excluded for maintenance when necessary.5) If the chiller works with an open tank, the pump must be installedon intake to the tank and on delivery to the chiller.Subsequent checks1) Check that the tank and the circuit are completely full of water andthat all the air has been expelled from the system.2) The water circuit must always be kept full. For this reason, carryout periodic checks and top the circuit up if necessary, or install anautomatic filling kit.3.3.2 Water and ethylene glycolIf installed outdoors or in an unheated indoor area, it is possible thatthe water in the circuit may freeze if the system is not in operation dur-ing the coldest times of the year.To avoid this hazard:a) Equip the chiller with suitable antifreeze protection devices, avail-able from the manufacturer as optional accessories;b) Drain the system via the drain valve if the chiller is to remain idlefor a prolonged period;c) Add an appropriate quantity of antifreeze to the water in circula-tion (see table).Sometimes the temperature of the outlet water is so low as to requirethe addition of ethylene glycol in the following percentages.Outlet watertemperature [°C]Ethylene glycol(% vol.)Ambienttemperature4 5 -22 10 -50 15 -7-2 20 -10-4 25 -12-6 30 -153.3.3 Expansion tankTo avoid the possibility of an increase or decrease in the volume of thefluid due to a significant change in its temperature causing damage tothe machine or the water circuit, we recommend installing an expan-sion tank of suitable capacity.The expansion tank must be installed on intake to the pump on therear connection of the tank.
