The plugs supplied are only suitable for use with the
following types of walls:
●
Concrete
●
Solid lightweight concrete blocks
●
Cavity block made of lightweight concrete
●
Cellular concrete
● Prestressed concrete - hollow ceiling/floor slabs
●
Natural stone with dense, close-grained micro-
structure
●
Solid calcium silicate blocks
●
Perforated calcium silicate blocks
●
Solid bricks
●
Vertically perforated (honeycomb) bricks
● Hollow floors/ceilings made of clay bricks, con
-
crete or similar
●
Solid gypsum boards
● Gypsum boards and gypsum fibre boards
●
Particle boards
The board material must be dimensioned with
sufficient thickness to ensure secure fixing.
Appropriate fixing material must be provided on site
for other types of wall constructions.
ATTENTION
Leaving a gap between the unit and the wall helps
back ventilation and may not be sealed or closed
off.
Cable glands must be laid at a distance of at least 2
cm from the hydraulic module.
5.3 Installation / hydraulic connection
to heating circuit
NOTE
Before connection to the heating system, the
heating circuit must be thoroughly flushed.
„Dimensioned drawings and drill patterns“, from
page 20
►
Secure all connections against twisting.
Cross-sections and lengths of the pipes for the
heating circuit are adequately dimensioned. In
doing so, always that the connection pipework
between the heat pump and hydraulic module are
also taken into account
The free pressing of the recirculating pump
produces at least the minimum throughput
required for the unit type (refer to “Free pressing”,
page 19).
The cables for the heating are fixed to the wall or
ceiling via a fixed point.
►
Insert the vent at the highest point of the heating
circuit.
► Take off the hood at the front of the hydraulic
module.
On the inside of the hood, there is a tongue-and-
groove joint along the circumference.
Lock the hood into the groove on the housing.
The connections for the heating circuit are located on
the underside of the device.
5.4 Safety module
The safety module for the heating circuit is in the extra
box.
Install the safety module at the connection provided
on the top of the device.
The safety discharge of the safety valve must be
discharged into the drain via a funnel waste trap in
accordance with the respective current standards,
guidelines and directives.
It is essential that the safety discharge is connected!
5.5 Expansion vessel
The expansion vessel for the heating circuit is
integrated. Always check whether the size of the
expansion vessel is large enough for the system.
If necessary, an additional expansion vessel must
be installed on site in accordance with the relevant
standards and guidelines.
NOTE
The admission pressure of the expansion
vessel must be adjusted to the system
(approx. 0.5 bar less than the system filling
pressure) in accordance with the calculation
to the relevant standards (EN 12828).
