Disregarding this warning can lead to serious injury or death.

WARNING!

Indicates a potentially dangerous situation.

Disregarding this warning can result in serious injury or death.

CAUTION!

Indicates a situation which may cause possible damage.

Disregarding this warning can lead to damage to property and the environment.

This symbol identifies user tips and particularly useful information, but not warnings or hazards.

Special warning signs

Some types of danger are represented by special symbols:

Electrical current Danger of burning or scalding

Validity

This instructions are especially for the on-roof installation of the solar panel array, for routing the piping and for start-up.

For other types of installation (in-roof, flat roof mounting) the instructions for the individual type of installation are applicable.

1 Safety

The operating and installation instructions of the respective control and pump unit are to be observed when installing piping and starting up, .

Only applicable for the unpressurized system (Drain Back)

Only applicable for the pressurized system

Handling instructions

•Instructions on actions are shown as a list. Actions of which the sequential order must be maintained are numbered. Î Results of actions are identified with an arrow.

1.3Avoid danger

DAIKIN solar systems are state-of-the-art and are built to meet all recognised technical requirements. However, improper use can lead to serious injuries or death, as well as cause material damage. To avoid any danger, only install and operate DAIKIN solar systems:

–as stipulated and in perfect condition,

–with an awareness of the safety and hazards involved.

This assumes knowledge and use of the contents of this manual, the relevant accident prevention regulations and the recognised safety-related and occupational medical rules.

1.4Proper use

The solar system may only be used for generating hot water and for solar-supported heating of hot water systems. The solar system must be installed, connected and operated only according to the instructions in this manual.

Any other use outside the above-mentioned use is considered as improper. Any resulting damages will be borne by the user/owner alone.

Proper use also includes observing the relevant maintenance and servicing conditions. Spare parts must at least satisfy the technical requirements defined by the manufacturer. This is the case, for example, with original spare parts.

1.5Instructions for operating safety

Working on the roof

•Installation work on the roof may only be carried out by authorised and trained persons (heating technicians, roofers, etc.) in compliance with the relevant Accident Prevention Regulations and with the use of suitable personal protection equipment.

•Material and tools must be secured from falling down.

•Barriers must be erected to prevent persons from entering the area below the roof where the work is being carried out.

Before working on the heating system

•All work on the heating system (such as installation, connection, and commissioning) may only be carried out by authorised and trained heating technicians.

•Switch off the mains supply before starting any work on the heating system and secure it against unintentional switch-on.

Electrical installation

•Electrical installations may only be carried out by qualified electrical technicians under observance of the relevant electrical guidelines and the regulations of the electric utilities company.

•Before connecting to the mains supply, check that the voltage specified on the type label of the heating system (230 V, 50 Hz) is the same as the available supply voltage.

Instructing the user/owner

•Before you hand over the heating system, explain to the user/owner how to operate and check the heating system.

3.1Transport and storage

3.1.1Transport

CAUTION!

The EKSV26P/EKSH26P flat solar panels are impervious to slight mechanical loading. However, impact, shock and walking on them should be avoided.

•The EKSV26P/EKSH26P flat solar panels should be transported and stored carefully in their original packing only and this packing should not be removed until shortly before installation.

•The EKSV26P/EKSH26P flat solar panels should be stored and transported flat on even and dry supports.

–Transport with forklift trucks or cranes is only allowed if on pallets.

–Up to 10 flat solar panels can be stacked and transported on top of each other.

The EKSV26P/EKSH26P flat solar panels are delivered wrapped in film. As long as the solar panels are secured on a pallet which corresponds to the size of the solar panel, then industrial trucks such as forklift trucks and stackers or cranes are suitable for transport. Other components of the solar system are supplied packaged separately.

3.1.2 Storage

The following should be taken into account when storing solar system components:

•All components should be stored in dry and frost-protected rooms only.

•Dismantled hydraulic components must be completely drained before being stored.

•Components must not be stored until they have cooled down.

•Current-carrying components must be permanently isolated from the power supply before storage (switch off fuses and main switches, remove cables) and must be secured against inadvertent restarting.

•The components must be stored in such a way that persons are not endangered by them.

The regulations in the respective documentation for other heating components apply for transport and storage of these products.

3.2System concepts

Solar systems are usually set up according to one of the following system layouts. This also includes the possibility of connection on the opposite side of the flat solar panels in each case.

Connection at opposite ends possible1) (possible from 1+ solar panels) Same-side installation connection (up to maximum of 3 solar panels)
