Clean fan guardgrill if necessary to avoid a reduction of ventilation.Use only hoses at the inlet and outlet of the pump withan inner diameter at least as large as the diameter of thepump’s tubing (to avoid overpressure at the outlet, andreduction of pumping speed at the inlet).Allow the equipment to equilibrate to ambient temperatureif you bring it from cold environment into a room prior tooperation. Notice if there is water condensation on coldsurfaces.Comply with all applicable and relevant safety require-ments (regulations and guidelines). Implement the re-quired actions and adopt suitable safety measures.Ambient conditions➨ Do not reach for this product if it has fallen into liquid.There is a risk of deadly electrical shock.
