The inlet and outlet coilconnections are marked using adhesive labels.• Insulate pipes on site.Additional information about air handling components with cooling function:• Insulate coil connections and pipes once the installation has been carried out toprevent the formation of condensation water. Condensate water that is formed accumulates in the stainless steel condensate trayand is drained via a drain spigot mounted on the condensate tray.• Install a siphon (See „Connecting siphon and water drains“ on page 37).32 PR-2006-0019-GB • Subject to modifications • Status 05/2009
