DESCRIPTION
Storage tanks are used to accumulate excess heat from its source. The source can be a solid fuel boiler, heat pump, solar collectors, fireplace insert, etc.
The NADS tanks only serve to store heat in a heating system. The NADOS tanks also allow heating or preheating of DHW in the inner vessel. The integration of the storage tank into a heating system with the solid fuel boiler enables optimal operation of the boiler at a favorable temperature during the operation of the boiler. The benefit is mainly the period of the optimal operation (i.e. with maximum efficiency) when the excess heat is stored in the tank.
The tanks as well as the possible tube exchangers are made of steel, without any treatment of the inner surface; the outer surface of the tank is provided with a protective coating. The tanks are made in volumes of 800, 900 liters. The particular versions are also equipped with a tube heat exchanger, each with an area 1.5 m2.
The NADOS type allows direct heating of the domestic hot water (DHW) in an inner enameled vessel, or its preheating or another water heater. The connection with the boiler usually allows direct heating of DHW in the inner tank to the required temperature, while the connection to solar collectors or a heat pump only preheats the DHW and it is necessary to include another, e.g. electric heater, which heats the water to the required temperature, or to install an electric heater into the storage tank, which can be an electrical heating unit TJ 6/4″.
The tanks are not intended for storing DHW – domestic hot water.
DESIGNING THE SIZE AND CONNECTION OF STORAGE TANK
An ideal size of the storage tank is designed by a design engineer, or a person sufficiently qualified to design heating systems. Product assembly must be implemented by an authorized person (confirmed in the warranty certificate).
When putting into operation, water has to be filled first into the inner tank
for HSW and the operating pressure inside it has to be kept, only then heating
water can be filled into the outer storage tank, otherwise the product may get
damaged!
The
manufacturer explicitly emphasizes the necessity of being particular in
testing the tightness of the heating circuit (radiators, piping joints, floor
heating, etc.) with the connection of the storage tank. No pressure grow in
the storage tank heating water compartment may occur above the maximum
operating pressure of 0.3 MPa, if the heating system is pressurized to higher
than the maximum operating pressure, the inner enameled tank may get
permanently damaged!

IMPORTANT NOTICES
Connection of internal tank for hot water must comply with CSN 060830, i.e. on cold water inlet is necessary to install a safety valve.
| We
recommend to start up the heating circle before commissioning and to clean
possible dirts caught in the filter and after this the system would be fully
functional.
---|---
| The
appliance has to be mounted at a convenient place, it means that the appliance
must be easily available for potential necessary maintenance, repair or
replacement, as the case may be.
No stop fitting can be put between the security fitting of the heating circuit
and the storage tank!!!
|
Recommended operating pressure of hot water circle is 0.4 MPa.
The reservoir is possible to use only in compliance with conditions stated on
performance plate and with instructions for wiring. It is also necessary to
observe terms for connection stipulated by some local electrical and water
companies as same as manual for assembling and operation besides statutory
accepted national regulations and standards.
Shut down the reservoir cold water intake if you are not using the reservoir
for longer than 24 hours or if the object with the heater is without presence
of any person.

Thermal insulation NEODUL LB PP
Insulation NEODUL of 80 mm thickness. It consists of an upper cover, flange
cover and hole caps.
Insulation is supplied in a separate packaging.
We recommend that the insulation was fitted at room temperature.
At temperatures significantly below 20 °C the insulation shrinks. This
disables its easy fitting.
DISPOSAL OF PACKAGING MATERIAL AND NON-FUNCTIONING PRODUCT
A service fee for providing return and recovery of packaging material has been paid for the packaging in which the product was delivered. The service fee was paid pursuant to Act No 477/2001 Coll., as amended, at EKO-KOM a.s. The client number of the company is F06020274. Take the water tank packages to a waste disposal place determined by the municipality. When the operation terminates, disassemble and transport the discarded and unserviceable heater to a waste recycling center (collecting yard), or contact the manufacturer.
