1. Safety information

1.1 Important information

We have carefully checked the text and pictures of this manual and provided the best of

our knowledge and ideas, however inevitable errors maybe exist. Please note that we

cannot guarantee that this manual is given in the integrity of image and text, they are just

some examples, and they apply only to our own system. Incorrect, incomplete and

erroneous information and the resulting damage we do not take responsibility. Please

understanding!

1.2 About this manual

This manual describes the installation, functions and operation of a solar station, which

integrates a solar controller. When installing the remaining components e.g. the solar

collectors and the storage unit, please be sure to observe the appropriate installation

instructions provided by each manufacturer. Installation, electrical connection,

commissioning and maintenance of the device may only be performed by trained

professional personnel. The professional personnel must be familiar with this manual and

follow the instructions contained herein.

1.3 Liability waiver

The manufacturer can’t monitor the compliance with these instructions or the

circumstances and methods used for installation, operation, utilization and maintenance of

this pump station. Improper installation can cause damages to material and person. This is

the reason why we do not take over responsibility and liability for losses, damages or cost

that might arise due to improper installation, operation or wrong utilization and

maintenance or that occur in some connection with the aforementioned. Moreover we do

not take over liability for patent infringements or infringements –occurring in connection

with the use of this pump station on the third parties rights. The manufacturer preserves

the right to put changes to product, technical date or installation and operation instructions

without prior notice. As soon as it becomes evident that safe operation is no longer

possible (e.g. visible damage). Please immediate take the device out of operation. Note:

ensure that the device can’t be accidentally placed into operation.

1.4 Description of symbols

Safety indication: Safety instructions in the text are marked with a warning

triangle. They indicate measures which can lead to injury of person or safety risks.

4. Attention Items for solar station installation

Note: In order to avoid jam the digital flow meter and in result to displays no flow on solar

station, the filter must be installed on the return and flow pipeline of solar station.

All devices connected to the controller must conform to the technical specifications of

the controller, assembly, installation and maintenance work may only be performed by

properly qualified and authorized personnel with a generally recognized qualification.

The solar station must be installed indoors, prior to installation, remove sealing caps

from solar station.

According to the manual of expansion vessel to install and adjust it, the pipeline for

connecting pump station and expansion vessel should be not insulated.

Safety valve: Risk of scalding from hot steam with discharge from the safety valve due

to heating and excess pressure in the hydraulic pipes. Using a copper pipe to drain the

discharged liquid from the safety valve to the barrel and disposed it in an eco-friendly

Filter
