Page 65 Piping installation No actions or adjustments are required. Example 2 The outdoor unit is installed at the highest point in the water circuit. The total water volume in the water circuit is 250 l. Actions: ▪ Because the total water volume (250 l) is more than the default water volume (185 l), the pre-pressure must be decreased.
Page 66 Piping installation 8.2.3 To connect the water piping NOTICE Do NOT use excessive force when connecting the field piping and make sure the piping is aligned properly. Deformation of the piping can cause malfunctioning of the unit. NOTICE When connecting the field piping, hold the nut on the inside of the unit in place using a spanner to provide extra leverage.
Page 67 Piping installation NOTICE For service purposes, it is recommended to also install a shut-off valve and drain point to the water OUT connection. This shut-off valve and drain point are field supplied. NOTICE Install air purge valves at all local high points. 8.2.4 To protect the water circuit against freezing About freeze protection Frost can damage the system.
Page 68 Piping installation WARNING Due to the presence of glycol, corrosion of the system is possible. Uninhibited glycol will turn acidic under the influence of oxygen. This process is accelerated by the presence of copper and high temperatures. The acidic uninhibited glycol attacks metal surfaces and forms galvanic corrosion cells that cause severe damage to the system.
Page 69 Piping installation NOTICE ▪ The required concentration might differ depending on the type of glycol. ALWAYS compare the requirements from the table above with the specifications provided by the glycol manufacturer. If necessary, meet the requirements set by the glycol manufacturer.
