The unit can also be wall mountedagainst a vertical wall capable of supporting the weight (forthis we recommend the use of the wall mounting kit Part No.LA610 on substantial brick/concrete walls or LA622 for studpartition walls).WARNING!IF THE UNIT IS TO BE WALL MOUNTED,ENSURE IT IS MOUNTED USING THECORRECT WALL MOUNTING KIT ANDTHAT THE WALL IS CAPABLE OFSUPPORTING THE OPERATING WEIGHTOF THE SYSTEM. ALWAYS CAREFULLYFOLLOW THE INSTRUCTIONS INCLUDEDIN THE KIT.Note:Refer to Specifications for unit weights(Section 3.4 - Technical Specification).Rear Mounting PointsThe unit is designed to operate safely under the following conditions: Indoor Use. Altitude up to 2000m. Temperature Range 5 - 40 C. Maximum Relative Humidity 80% at 31 C decreasing linearlyto 50% at 40 C, non-condensating.Unit Rear Mounting PointsThe unit is in Installation Category II, Pollution Degree 2, as SafetyStandard IEC1010-1.PURELAB Ultra Mk2 Version 3 11/08Downloaded from www.Manualslib.com manuals search enginePage 13

PURELAB Ultra Mk2 Operator ManualMains power socketFuseON/OFFswitchMains power leadELGAElectricalThe units can be connected universally to any electricalsupply in the range of 100 - 240V and 50 - 60Hz. The mainslead is supplied with a molded plug on one end and a moldedconnector to the unit on the other. The unit should beconnected to an earth. The unit includes a battery which willrequire changing on a periodic basis, typically every 3-5years. (Contact local Service provider)WARNING!Electrical ConnectionsDANGER OF EXPLOSION IF BATTERY ISINCORRECTLY REPLACED. REPLACEONLY WITH THE SAME OR EQUIVALENTTYPERECOMMENDEDBYTHEMANUFACTURER (3 VOLTS, LITHIUMCR2032). DISPOSE OF USED BATTERIESACCORDING TO THE MANUFACTURER’SINSTRUCTIONS.Drain/FlushA semi-rigid flexible connection to a sink or suitable draincapable of at least 2.0 l/min is required. The drain pointshould have a gravity fall below the level of the unit and anyconnections direct to drain should have an air-break devicefitted. On the Genetic & Bioscience units a separate flush lineto drain is required. The drain and flush drain lines should runindividually to a convenient drain point.Feed WaterThe feedwater should be potable water, pre-purified usingreverse osmosis, deionisation, or distillation. If using a supplyother than reverse osmosis treated, it is stronglyrecommended that a 0.2 micron membrane filter is installedprior to remove colloidal impurities. The feedwater shouldenter the PURELAB Ultra via an 8mm (5/16") O/D semi rigidtube, and should be in the temperature range 1 to 40 C (34to 104 F). To ensure optimum performance it isrecommended that the feedwater temperature be between 10to 15 C.CAUTION!Operating with feed water temperaturesoutside the range from 1 to 40 C (33.8 to104 F) will cause damage to the PURELABUltra unit.For pressurized feeds, the minimum direct inlet pressure is0.07 bar (1.0 psi) and maximum inlet pressure is 0.7 bar(10 psi). Feedwater pressures up to 4 bar (60 psi) must bereduced using a pressure regulating valve (Part No. LA652).CAUTION!High feedwater pressures which mayexceed 4bar (60 psi) must be reducedusing a pressure regulator with built inpressure relief (Part No. LA575).Failure to install the correct pressureregulator will cause damage to thePURELAB Ultra unit.Reservoir feeds to the PURELAB Ultra unit should bepositioned at the same height, or above the unit, to provide apositive flooded inlet pressure of approximately 0.07 bar(1 psi).Page 14Downloaded from www.Manualslib.com manuals search enginePURELAB Ultra Mk 2 Version 3 11/08
