PRIOR TO THE INSTALLATION OF THE TANK, READ CAREFULLY THIS
MANUAL!
Dear customer,
The Works Cooperative of Dražice – Machine Plant, Ltd., would
like to thank you for your decision to use a product of our brand.
The manufacturer reserves the right for engineering modification
of the product.
The product is designed for permanent contact with drinkable
water.
1DESCRIPTION
Accumulation tanks serve for the accumulation of excessive energy from the heat source. The source may
be a solid fuel boiler, heat pump, fireplace inserts, etc.
The NAD type tanks serve for the accumulation of heat in the heating system; the operation agent
is heating water. The accumulation tank inclusion in the heating system with the heat source provides ideal
operation of the heat source under beneficial temperature conditions. The main benefit is the optimising
of the heat source operation (i.e. with maximum efficiency) when the unconsumed heat accumulates
in the tank.
The tanks are made of a steel plate and tested by 1.5 MPa multiple of operation pressure value,
without any inner surface treatment. NAD 100 v1 and NAD 250 v1 are insulated with hard polyurethane
Freon-free foam with 42 mm thickness, with great insulation ability. Top housing is made of sheet metal
and with powder paint surface finish.
The installation conditions
NAD 100 v1 is stationary and suspension accumulation tank for vertical installation on solid, sufficiently
bearing base or wall. NAD 250 v1 is only stationary tank for vertical installation on solid, sufficiently bearing
base or wall.
Accumulation tanks NAD 100 v1 and NAD 250 v1 cannot be used for accumulation of TV –drinking water.

2THE DESIGN OF SUITABLE VOLUME
AND TANK INSTALLATION
The design of the accumulation tank volume is performed by the heating designer or a person sufficiently
qualified for the design of the heating systems.
Installation of NAD 100 v1 and NAD 250 v1 must be performed by a specialist plumber who will confirm
the fact by a stamp in the warranty sheet.

Recommendation
Prior to commissioning we recommend leaving the heating circuit circulation pump in operation
for the period of at least 24 hours. Potential contamination from the system is arrested in the filter.
After the filter cleaning, the system is fully operable.
