The PURELAB QUEST unit should be installed on a at, level surface, in a clean dry environment 15 - 25 ˚C. The unit can also be wall mounted
using the LA735 wall mounting kit against a vertical wall capable of supporting the combined weight of the unit and mounting kit.
Temperature 10 - 25°C / Minimum Pressure 2.0 bar - 30 psi (<2 Bar install LA648), Optimum
Running Pressure 4.0 bar - 60 psi, Maximum Pressure 6.0 bar - 90 psi. (Regulate to 4 bars using LA512).
The drain and overow tubes will require a drain or a sink capable of handling at least 1.5L / Min with a gravity fall
below the level of the unit. Any connections directed to drain or sink should have an air-break device tted.
a) Use lifting aids to move the product into position. (Fig.1) b) Place the product on a at level surface, remove from the packaging. (Fig.2)
a) ISOLATE the water supply to the sink (Potable water supply).
b) Cut the 15mm copper or plastic inlet water pipe with a suitable 15mm tube cutter.
a) Use 6 X ow bends from the basic installation kit LA762.
b) Fix 8mm ow bends to the wall if required. (Fig.6) c) Clip in the 8mm pipe. (Fig.7) d) Example of an air-break device. (Fig.8)
