General Information:
•The P1PVKY & P1PVCDKY are coldandambient watercoolers designedfor connectiontoa
mains supplyof potable water.The coolershouldnot beconnectedtowater supplies of
unknown bacterial quality or those thatarenotalreadyfitforhumanconsumption. The machine
should onlybe connectedtoa potable drinkingwatersupply
•Thisunit is suitable for indoor use in domestic, commercial& industrial locations. Theyshould
not besitedinlocations where theymaybe subjectedtorainorsnow
CoolingSystem:
•The P1PVKY & P1PVCDKY models use the OASIS Pressure Vessel DirectChill (PVDC)
coolingtanksystem. The coolingtankis manufactured from304Stainless Steelwhichis non-
corrosiveandinert.
•The coldwater temperature ispreset at the factoryat approximately7°C – thewatertemperature
is controlledbya thermostat thatis locatedonthe backoftheunit. Coldwatertemperatures may
be adjustedvia a slottedscrewonthe bodyof the control(canbe accessedthrough wires on the
condenser). Turningthisscrewinthe clockwise directionwill make thewater colder (andvice
versa)
•The significant benefit of theOASIS PVDC system whencomparedtoso-called“coil onCoil”
DirectChill systems is the increased quantities of coldwater availableondemand.
Ambient Water Circuit:
•The water inthe ambientwatercircuitis not cooled -the temperature ofthe water will be the
same as thetemperature of the water that comes outof thebuildingwater supplyandthe
ambient room temperature. The ambientwatershould be flushedafter longperiods of nonuse
Compressor:
•The compressor operates at220-240Vandat50Hz. Itusesthe hydrofluorocarbonrefrigerant
R134a whichis a non-Ozone depletingsubstance with a Global WarmingPotential of 1,300.
The compressor is controlledbyan electromechanicalthermostat thatcontrols the temperature
of thewater inthe directchillunit
CupDispenser:
•The P1PVCDKY contains an integratedcupdispenser builtintothe topof the cooler. This isthe
onlydifference betweenthe P1PVKYand P1PVCDKYmodels

Installation:
Eachinstallationmustinclude the followingcomponents
•An isolatingand nonreturn valvemust be fittedatthe point of connectiontothewater supply.
•An antileakdevice must be fittedatthe point of connectiontothewatersupplydownstream
of theisolatingandnonreturnvalves.
•Pressure limitingdevices shouldbeinstalledtoprotectthe coolerandfeedpipework from
waterpressuresurges inlocationswhere theymayoccur
•Eachcooler must have an independent isolatingtap.This is intendedsothatthecoolercanbe
replacedwithoutdraininglonglengths of piping
The followinggeneralguidelines applytothe pipework
•Pipework shouldavoid light fittings andelectricalandgas piping
•Pipework inpublic viewshould be securelyandneatlyfixed.
•Allpipework shouldbe accessible andclearlylabeled.
•Pipework shouldbe laggedwhen necessaryto avoid freezingor high temperatures.
The customer shouldbe informedinwritingof the locationof allisolationvalves
Sanitisation:
EPDWA guidelines state:
•Allcoolers must besanitized before commissioning
•Whena customer signs up tothe sanitisationprogram, the coolershouldbe sanitizedevery6
months
•Sanitisationshouldbecarried out inaccordance with the manufacturer’sinstructions –see
attacheddocuments.
Connecting Water Cooler toMains Supply:
AllOASIS POUwater coolers are suppliedwitha push-fitconnector that should beusedto connect the
coolertothe mains watersupply. OASIS recommends thatthese guidelines shouldbe followedwhen
installingthecooler:
Use ”diameter tubingto connect the mains supplyto the watercooler. Although 6mm tubingwill
appeartofit, itis actuallyapproximately5%smaller insize. The use of 6mm tubingwillresult ina leak.
In anymainswater system, itis possible for“spikes” orsuddenfluctuationsinpressure tooccur. These
canresultininstantaneous pressures inexcess of7bar (100psig) tooccur. OASISrecommendthatall
installationsinclude a pressure regulator, suchas a slowflowregulator, which shouldbe locatedinfront
of the cooler’s water inlet.
Installing thewater cooleratyour customer’s premises
