Installation Carefully lift the water protection barriers out of the interior of the unit. Do not damage any com- ponents when lifting out. CAUTION In the air outlet area, the air temperature is approx. 5 K below the ambient temperature. Under certain climatic conditions, an ice layer can therefore form in the air outlet area.
Hydraulic installation After correct placement on the ventilator ring plates (②), 8 screw threads (⑤) protrude from each water protection barrier (④). IMPORTANT Components and lines for desuperheating must be able to withstand temperatures up to 90°C. IMPORTANT Dirt and deposits in the (existing) hydraulic system can Use the mounting material from the accessory cause damage to the heat pump.
