Important information
This guide is designed to describe the operation, installation and maintenance of
the heat pump as comprehensively as possible. The description has been written
as far as possible so that it can be followed step by step.
Please note that the guide consists of three separate parts, therefore it is espe-
cially important that the installation contractor reads the entire manual before
commencing installation.
The guide is in two parts, one for the user and one for the installer. The table of
contents sets out clearly the various sections of the manual.
Warning! The Rego 600 control unit contains an advanced settings level which
should only be accessed by the installer. The end user should never change any
settings on this level, since this might cause problems with the operation of the
heat pump.
• Before the heat pump is commissioned, the heating system and the heat pump
must be filled and vented.
• Hot and cold connections might need checking after delivery.
• If the heat pump has to be carried down steps or stairs it can be tilted temporar-
ily with the compressor downwards, but never for long periods.
• The heat transfer fluid system must be in operation when venting the system.
See chapter on refilling the heat transfer circuit.
• Three phase heat pumps incorporate an alarm if the phasesare incorrectly wired.
