General notes Safety This unit is constructed and tested according to EN 61010-1 / VDE 0411 Part 1 and left our works in perfect and safe condition. In order to maintain this condition and operate safely the user must take note of the following safety information and warnings contained in these instructions. -
Page 9: Mechanical Installation
Mechanical installation Remove the external protection film as soon as possible as this can General stick due to sun rays. The water sampler must be installed so that it stands higher than the sampling point. It can be installed outside and mounted on a concrete foundation or solid level ground. -
Page 10: Installation
Mechanical installation Recommendations and The suction hose must always be submerged in liquid at the sampling accessories point. Suitable measures for this are: Weight the end of the hose using a short length of V2A tubing or fixing the hose to the channel (tank) wall using a hose saddle or the submersion armature (can be ordered as an accessory). -

Page 12: Electrical Installation
Electrical installation The sampler is delivered with a 3core mains cable (length approx. 1.4m) connected to a 2 pin plug with earth contact. This cable is fed through the sampler left side panel and is already connected to the mains terminals in the terminal box. Terminal box Open the cabinet door. -
