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.

Symbols

The instructions contain different warning symbols, which,
together with text, indicate to the user that there are risks
involved with actions to be taken.
