Note: Incorrectly connected wires may lead to electric malfunction and can damage the units. See safety instructions on pages 2 and 12 for electric installation compliance and damaged cable.

FINISHING TOUCHES

Use a thermal tube to wrap the joints and wrap the tube tightly with ethylene tape.

Fix the wrapped pipelines vertically on the external wall with duct through and pipe clamps, available at DIY-stores.

Fill the gaps in the holes made for the pipeline to prevent rain-water from entering.

Lead the water drainage pipe to a suitable drainage point, making sure that the water can flow through freely.
