cable, with cross-section 0,75 mm 2 . Maximum cable length
300m.
The connection must comply with the current rules and
regulations.
3.4 Condensate Drain Trap
The condensate drain trap must be connected to the threaded
tube under the unit. Additionally, an odour trap is required in
the waste water system. For hygienic reasons, between the
drain traps an air gap of at least 20 mm must be provided.
• Condensed water drain G 3/4 connection for the condensate
