The “Model Device Information” is an integral part of
the product. It supplements the operating manual “Air/
Water Heat Pump, Outdoor Installation”. In addition to
this “Model Device Information”, the operating manual
“Air/Water Heat Pumps, Outdoor Installation” must al-
so be available to you.
Since this “Model Device Information” was written for
several different models of the unit, always comply with
the parameters for the respective model.
The “Model Device Information” is intended only for
persons assigned to work on or operate the unit. Treat
all constituent parts condentially. The information con-
tained herein is protected by copyright. No part of this
information may be reproduced, transmitted, copied,
