Boiler Protection Against Overheating; Transport, Manipulation And Storaging - ATTACK DPX15 Instructions For Use Manual

Advantages
Boiler installation with accumulation tank brings several advantages:
- lower fuel consumption (up to 30%). Boiler works at full output, until the fuel is burned-out, while
optimum efficiency is kept
- long chimney and boiler life-time and minimum creation of acids and condensate
- option to combine with other heat sources - solar collectors, etc.
- combination of boiler with underfloor heating
- comfortable and ecological heating

Boiler protection against overheating

ATTENTION: Following the norm EN
303-5, the aftercooling circuit against
boiler overheating cannot be used for
other purposes than boiler protection against
overheating. Valve at the cooling water inlet
into cooling circuit must be permanently open
and boiler cooling circuit must be connected to
functional distribution of cooling water (e.g. to
cold water distribution of water supply system)
with temperature of 10-15°C and operation
pressure of 2-6 bar. The STS20 valve at the
aftercooling circuit outlet with sensor in the boiler
rear part. Protects boiler against overheating in the
following way. If water temperature exceeds
95°C, it lets the water from water supply system
into aftercooling circuit to absorb the warmth. In
case of boiler overheating and opening of the
STS20 valve, the permanent outlet of warmed
water from boiler´s aftercooling circuit into flow-off has to be ensured.
In case that circulation of cooling water through aftercooling circuit is not ensured at opening of
the thermostatic valve STS20, there is a danger of boiler damage! In this case the warranty for
boiler expires.

Transport, manipulation and storaging

Producer puts the article on pallet and fits it on with technological screws. It is packed in the paper
box, binded by sticky tape and wrapped into stretched foil.
Transport, manipulation and storaging of packed product is permitted only on this pallet. For
manipulation to boiler´s standpoint there are suspension eyes for manipulation with elevator,
available after removing of upper cover.
Only approved person can ensure manipulation with the boiler.
Instructions to liquidation of the product after its life-time expiration
