1 General

Depending on the type and design, WIKORA tanks are suitable for water storage. The maximum working pressure and working

temperature can be found in the technical data.

Set-up, installation and commissioning must be undertaken by a qualified specialist, who must observe these instructions.

The site of installation must be frost-protected according to DIN 4753.

When setting-up and installing the tank, the following regulations should be considered:

In addition to the technical rules in force DIN 1988, DIN 18160, DIN 4753, DIN 4109, DIN 4708, DIN 4751 section 2-4 energy

conservation law and VDE regulations are to be observed. Moreover, the relevant regulations of the suppliers as well as legal

building regulations are to be considered.

2 Transport and installation

In order to prevent damage during transport, the packaging should only be removed at the site of installation. During shipment,

it should be ensured that the tank does not come in contact with any spiky or sharp items, nor is damaged through dropping or

knocks.

During installation, the tank must be disconnected from any humidity carrying components. Moreover, sufficient space for

maintenance and cleaning purposes should be kept free in front of, beside, above and behind the tank.

The pre-assembled PS-jacket can be dismantled for installation. Damages which have been caused in the thermal insulation

during installation must be professionally repaired.

The PS-jacket including rosettes are to be placed at the site of installation before installing the pipeworks.

Errors excepted.

3 Dimensions and connections

Chilled water buffer tank on base ring, interior not coated, exterior primer-painted for thermal insulation, 25 mm thermal

insulation and PS-jacket in RAL 9220, pre-assembled with rosettes and cap.

5 Installation

All pipes connecting to the tank should have removable connections (fitting/flange). Pipe thread seals with teflon are to

be avoided.

All tank connecting pipes are to be planned, constructed and tested according to the technical rules in force, as well as to the

corresponding norms and regulations in accordance with their application and supply medium.

Sensors and thermostats necessary for temperature control must be securely and permanently positioned on the tank

(immersion sleeve and sensor rail).

The tank’s venting and draining facilities must have the appropriate dimensions and be correctly installed.

The installation company is responsible for the correct execution of work and for the safe and careful insulation of the pipes.

All factory-made, non-insulated surfaces must be insulated in a professional manner on site.

6 Commissioning

Before putting into operation, the entire system should be flushed through. Particles in the system compromise the

operating reliability.

Fill the heating system slowly with water and vent all the air.

Start-up the system.

Before the handover of the system to the end user/owner, the plumbing contractor should ensure that the

system is tested to full load, controls are set and that pipe work and connections are without leaks. Afterwards,

the end user has to be instructed in the operation and handling of the tank, as well as the system. The instruction

must to be documented in the installation and maintenance record.

Please note that the operation and lifetime of the system depend decisively on a regular maintenance.

7 Maintenance and wear parts

Regular maintenance increases the lifetime and operation reliability of the system.

A damp cloth is sufficient to clean the outer parts. Please avoid using any abrasive or solvent cleaning.

8 Recycling and disposal

The products are specified and manufactured according to VDI 2243. The products are mechanically separable and 100%

recyclable. Make sure that the components are disposed according to the relevant regulations.

Errors excepted.
