Towards the inside of the building
Insert the condensate pipe (wall duct accessory)
through the wall duct (accessory) (using lubricant)
and connect it to the condensate nozzle using the
enclosed plastic elbows.
“Wall duct installation instruction”
If the condensate pipe is not routed inwards, the front
and rear openings in the wall duct have to be sealed
with the enclosed plugs.
“Internal condensate line connection“, page 30
6.2 Connection to the heating circuit
1.
If no wall duct is used, route the fixed piping of the
heating circuit outdoors below the frost line.
2. Flush the heating circuit thoroughly before con-
necting it to the heating system.
IMPORTANT
Damage to the copper pipes due to impermissible load!
►
Secure all connections against twisting.
Cross-sections and lengths of the pipes for the
heating circuit are adequately dimensioned.
The free pressing of the circulation pumps at least
results in the minimum throughput required for the
device type (
“Technical data / scope of sup-
ply”, page 16).
The hydraulic system must be equipped with a
buffer tank, the required volume of which depends
on your device type.
“Technical data / scope of supply”, page 16
The lines for the heating are fastened to the wall or
ceiling via a fixed point.
3. Insert the vent at the highest point of the heating
circuit.
Make sure that the working overpressure (
“Tech-
nical data / scope of supply”, page 16) is complied
with. Attach the enclosed sealing plate into the recess
in the housing floor.
1 Sealing plate
2 Heating water feed-throughs
3 Electric cable feed-throughs
4.
Connect the device to the fixed piping of the heat
-
ing circuit via vibration decoupling (stainless steel
corrugated pipes, accessory). You must install
them to prevent the transfer of structurally borne
sound to the fixed piping.
NOTE
If an existing system is being replaced, the
old vibration decoupling may not be reused.
“Vibration decoupling installation instruction”
1 Heating water outlet connection (flow)
2 Heating water inlet connection (return)
3 Condensate drain pipe
Route the stainless steel corrugated pipes
through the feed-through in the housing floor and
screw them onto the two pipes in the wall duct.
Connect the supply line first, then the return line.
6.3 Pressure safety
Equip the heating circuit with a safety valve and dia-
phragm expansion vessel in accordance with local
standards and guidelines.
Also install filling and draining devices, shut-off devic
-
es and non-return valves in the heating circuit.
