1 About the instructions
1.1 Introduction
These instructions are split into two parts: installation
instructions and service instructions.
The installation instructions start by describing DHP-AX
data. The installation instructions later give instructions in
a logical order covering unpacking, installation procedure,
and checking the installation.
The service instructions contain information about the
heat pump’s function and control. The service instructions
also contain a complete menu description and covers
troubleshooting in-depth.
The first two sections,
1 About the instructions and 2 Safety
precautions are general sections and apply to all the
instructions, i.e. the installation instructions and service
instructions.
References to chapters and sections within the instruc-
tions are in italics, e.g.: 1 About the instructions.
References to menu options in the heat pump’s control
system are in upper case, e.g.: INFORMATION -> OPERAT.
-> AUTO.
All figures in the instructions are numbered to help install-
ers and service technicians refer to them easily.

together with text, indicate to the user that there are risks
involved with actions to be taken.
