Observing Instructions

This manual is intended for authorised and trained technicians who have experience with the proper installation and start-up of 
heating systems on account of their technical training and knowledge.

All procedures required for installation, start-up, operation and adjustment of the installation are described in this instruction 
manual and associated instruction manuals. Please read this manual carefully and thoroughly before proceeding with the instal-
lation and initial start-up or modification of the system.

Relevant documents

Documents listed below are part of the technical documentation of the Daikin solar system and therefore must be observed. The 
documents are included in the scope of supply of the individual components.

– Air-water heat pumps EKHBH*/ EKHBX*; Operating and installation instructions
– Solar panels EKSV26P/EKSH26P: Installation instructions
– Solar add-on for air-water heat pump system EKSOLHWAV1. Installation and operating instruction manual.
– Process water for air-water heat pump EKHWE*/EKHWS*. Installation instructions
