Hydraulic connections Drain for condensate Hydraulic connections NOTICE Pipe connections, general Damage due to risk of frost! If the condensate freezes and cannot be routed away from the heat NOTICE pump, the evaporator may be damaged. Residue in the pipework can damage the system. ▶...
Hydraulic connections Connect the heat pump to the indoor unit NOTICE Material damage due to excessively high tightening torque! If connections are tightened too tightly, the heat exchanger may be damaged. ▶ When installing the connections, the tightening torque should be no more than 150 Nm.
Side cover and transport fitting Side cover and transport fitting Electrical connection ▶ Remove the side cover. NOTICE Malfunction due to faults! High-voltage lines (230/400 V) in the vicinity of communication lines can cause the heat pump to malfunction. ▶ Route sensor cable and shielded CAN-BUS cable separately to power cables.
Electrical connection ▶ Route the connection cables through the cable ducts. – Remove the rubber grommet from the outdoor unit for the respective cable. – Pierce the rubber grommet and place it on the cable. – Feed the cable through the cable channel so that a sufficient part of it comes through.
