oventrop Unibox E RTL Einbauanleitung Seite 2

Description:
Installation set "Unibox E RTL" for temperature limitation of heating sur-
faces with return temperature limiter, consisting of:
Wall box unit with integrated return temperature limiter, venting and
flushing valve and cover plate, valve connection G
"Euro" cone for Oventrop compression fittings.
Temperature range: 20-40 °C (return temperature)
Item no. 1022631 (white), 1022641 (chrome plated)
Installation and assembly:
When using the floor as surface heating, the lower edge of the "Unibox
E RTL" should be at least 20 cm above the finished floor, the front edge
should be on the same level as the finished wall. The thickness of pla-
ster and tiles has to be observed.
The wall box unit has to be installed with the hole pointing downwards.
Alignment and fixing are made by use of the enclosed elbows. They
can be fixed at the side of the wall box unit in different positions.
Then the wall box unit is sealed in the wall. The valve is protected by a
cover made of corrugated cardboard.
For a simple installation of the vertical pipework, place the pipe conduit
unit item no. 1022650 into the wall below the wall box unit, shorten if
required. Later, the front cover of the pipe conduit unit will be under
plaster.
When laying the floor as surface heating, the thermal and sound insula-
tion of the floor construction must comply with the valid rules, stan-
dards and regulations.
When installing the pipework, the correct sequence has to be observed
to ensure a perfect function of the "Unibox E RTL" (see installation
sketch):
– provide derivation from the supply pipe of the two pipe heating
system.
– installation of the surface heating circuit; like a spiral to guarantee
a constant temperature distribution.
– connection of the pipework to the "Unibox", marked direction of flow
has to be observed. Valve always behind the surface heating
circuit. Remove protection cover and the "Unibox E RTL" as well as
the front cover of the pipe conduit unit.
– installation of the connecting pipe to the return pipe of the two pipe
heating system.
The surface heating can be installed with any standard pipe material.
The Oventrop programme includes suitable compression fittings for
copper and plastic pipes as well as the composition pipe "Copipe".
The corresponding installation instructions have to be observed. An
open ring spanner 30 mm, e.g. Oventrop item no. 1401091, is recom-
mended to tighten the fittings.
The installation is filled and bled, e.g. at the valve. Then carry out leaka-
ge test and remount protection cover of the valve as well as the front
cover of the pipe conduit unit.
Important note for heating up:
After all plastering is finished, a concrete screed has to be laid which
conforms to the relevant standards. To avoid any cracks in the concrete
floor of the anhydrite concrete floor, heating up of the system must be
carried out according to EN 1264-4.
Start heating up:
– at the earliest 21 days after having laid the concrete floor
– at the earliest 7 days after having laid the anhydrite concrete floor
Heat up slowly
3 days with a flow temperature of about 25°C and then
4 days with a flow temperature of about 55°C
Flow temperature is only controlled by means of the boiler control.
Opening of valve of the "Unibox E RTL": Turn handwheel of the return
temperature limiter to the maximum value.
Instructions of the concrete manufacturers are to be observed.
Important note for putting the system into operation:
The recommended temperature range of the return temperature limiter
is between 25°C and 40°C.
The maximum permissible concrete temperature near the heating pipes
may not be exceeded:
– 55°C for concrete and anhydrite concrete
– 45°C for mast asphalt concrete
– or according to the instructions of the concrete manufacturer
After having completed all building work, remove protection cover and
mount white or chrome plated cover plate.
