HYDRAULIC ASSEMBLY
All GoldLine and RedLine boilers are hanging (except
AsDC-W
), vertical devices and
after taking down external metal cast, should be hung on the wall using attached
mounting screws.
Electric heating boiler has to be connected to the central heating system using
couplings (¾”, 1” or 1¼” – depending on model) according to the direction of water
flow (see glued arrows on boiler). Connection to be made in accordance with PN-
91/B-02413 (open systems), PN-91/B-02414 (closed systems) or applicable
regulations valid in the country of installation. Central heating system has to be
thoroughly flushed prior installation. Non-return valves (see upper picture on the
right) are mandatory for proper
AsD-W
boiler operation (not supplied with boiler).
For
AsDC-W
(see bottom picture on the right) one-way valves for C.H. and D.H.W.
are factory assembled. Legend:
1
– C.H. feed,
2
– D.H.W. feed,
3
– circulation,
4
–
cold water inflow,
5
– C.H. return.
ELECTRICAL ASSEMBLY
Connection to the electrical system needs to be done in accordance with regulations applicable in the
country where the given boiler is installed and therefore must be done by a qualified electrician only.
Boilers are designed for alternating current, 3-phase power supply (400V 3N~50Hz). Models with 4, 6, 9, 12
and 15kW powers are also available without any processing in 1-phase version (230V 1N~50Hz), greater
powers can also be prepared in 1-phase version upon request. Boiler’s power supply is connected to
terminal strip labeled as L
1
L
2
L
3
N or to switch ignition (for
AsBII
,
AsHN
and
AsBIV
). PE wire needs to be
connected to screw on mounting plate. Technical data table (below) provides information on the cross-
section connecting power cord, the applicable parameters of the main fuse protecting boiler, as well as
estimated heated areas for main and alternative heating source. Boiler should be connected to permanent
electrical system via device enabling boiler’s disconnection from heating source at all ends, with the
distance between contactors not less than 3mm.
