Upon receipt, please check delivery for
possible damages caused during transport.
Carry out visual check of the protection caps for
damages. Please check valve inner for contam-
ination.
In case of such or similar faults, only accept
delivery under reserve. Lodge complaint with
due consideration of the deadline.
Please only remove protection caps and trans-
port protections immediately before installation.
5.2 Installation of “Floorbox”
The possible depth of the water meter
has to be considered during installation!
The depth is determined by the designated
heat meter and produces the measure T1. The
frame has to be pulled out according to the
calculated depth.
After installation of the “Floorbox”, the supply
pipe is laid from one room to the other. The
individual heating surface circuits are
connected via derivations from the supply pipe
(see illustr. 5.2).
5.3 Filling
The heating system has to be filled and flushed.
Add an antifreeze liquid for frost protection.
5.4 Bleeding
The venting and flushing valves of the “Floorbox”
as well as those of the succeeding “Unibox”
can be used to bleed the system even under
working conditions.
5.5 Leakage test
The installation has to be checked for leaks and
the result has to be documented in a record.
5.6 Subsequent installation of heat
meters
Standard heat meters with flat sealing bodies
can subsequently be installed in the return pipe:
• with a length of 110 mm and G
3
⁄
4
male
threads and
• with a length of 130 mm and G 1 male
threads.
The double regulating and commissioning valve
in front of the meter stool piece and the ball
valve behind it, must be closed off.
The couplings have to be unscrewed.
The sealing surfaces should be cleaned and
new flat seals should be used during assembly.
A heater meter body with a length of 130 mm
and G 1 male threads is mounted directly
between the couplings.
When using a heat meter with a length of 110 mm
and G
3
⁄
4
male threads, the reducers have to be
screwed onto the body first. After that, the body
is mounted between the couplings.
The water meter bodies and the collar nut of the
coupling are to be lead sealed.
The ball valve and the double regulating and
commissioning valve have to be opened and
the heating system has to be bled and checked
for leaks.
Due to the heat meter, the pressure loss within
the installation is increased. The presetting of
the double regulating and commissioning valve
“Hycocon VTZ” has to be increased in such a
way that the initial design status is reproduced.
