5.4 Heating and cooling water connections for units with factory-mounted valves
5.4.1 Mounting connections
• At the beginning of the fitting procedure, remove caps on the water inlet and outlet
pipes.
• Fit the connections while ensuring they are free of mechanical stress.
Risk of damage to the unit!
During installation, the connecting nut on the heat exchanger must be countered
using a suitable tool. All on-site and factory-provided piping and valves with cooling
medium that are not fitted directly above the condensate pan must be insulated on-
site by others.
