1 General

Depending on the type and design, W IKORA tanks are suitable for heating and / or storing DHW and / or heating water. The
heating is achieved indirectly via heat generators, if applicable, from different heat sources. 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 and should be in direct proximity to the heat
generator.

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.

Important: The exhaust pipe must be at least as big as the safety valve outlet in width. It may not have more than 2 bends and
should not be longer than 2 m. If for any compelling reasons 3 bends or a length up to 4 m are required, then the entire exhaust
line must be designed one nominal size larger. More than 3 bends, or a length exceeding 4 m is prohibited. The exhaust pipe
must be installed with downward gradient. The drain line behind the funnel must feature at least the double width of the valve
entrance. A sign is to be attached close to the exhaust pipe of the safety valve or on the safety valve itself. „For safety reasons
water may leak from the exhaust pipe during the heating process! Do not lock! "The operability of the safety valve is to be
checked at regular intervals by means of de-ventilation.

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.

Please note that the insulation provided should be kept in a dry place at least 24 hours at a minimum temperature of
20°C before installation.

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.

The thread diameter of the heating safety valve depends on the nominal capacity of the water space and the maximum heating
capacity of the heat generator. It can be determined as follows:

Reaction pressure Max. heating capacity of the heat generator

1,5 bar 36 kW 72 kW 144 kW 252 kW 433 kW 650 kW
2,0 bar 43 kW 86 kW 172 kW 302 kW 518 kW 778 kW
2,5 bar 50 kW 100 kW 200 kW 350 kW 600 kW 900 kW

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 heating system.
 While the System is heating up, water will leak out of the safety valve.
 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. Decalcification at regular intervals may be
necessary in highly calcareous water areas. Attention – only valid for heating tanks with hot water supply.

A chemical decalcification can be carried out by a specialist using an approved decalcifier and taking the appropriate
precautions.

1. The safety valve protects the tank against excess pressure. The functional capacity must be checked at regular intervals
by venting. If an expansion vessel is used, the safety valve is not, or only rarely, required. Over a longer period of time
therefore, it can become blocked and not function when needed.

2. If there is a danger of freezing, the DHW tank should be permanently heated or completely emptied.

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

8 Warranties and guarantee

The product warranty is based upon the legal regulations of the German Civil Code and the Consumer Protection Act.
The warranty of the different products is shown in the table below. The correct installation and operation as well as the annual
maintenance of the tank are a prerequisite. During the first 12 months we guarantee that the products are free of any faults, as
of the date of the invoice. During this period, any occurring defects will be corrected free of charge. From the 2nd operating
year, there is a tank warranty, but this excludes assembly and disassembly costs. All other claims are excluded. Repairs and
costs which occur due to damage, inappropriate installation, chemical, electrochemical or electrical influences, incorrect
operation or improper manipulation, are excluded.
Furthermore, the warranty becomes invalid if the appliance has been modified through the installation of externally supplied
parts or through irregular professional maintenance.

Subject to our general terms and conditions.
