Preparatory Work - Kermi Ascotherm eco KRN41 Mode D'emploi

Directions for installation
Danger
Life-threatening situation!
For devices with electrical components: provide
a fault protection device during the installation,
tripping limit < 30 mA.
Switch off the power supply prior to installation.
Do not attach a cable to the underfloor-convector.
Do not roll cables.

Preparatory work

Make sure, that the site is suitable for installation,
refer to technical data.
Select screws and dowels (not included in the
scope of supply) which correspond to the structural
situation.
Make sure, that an acoustic insulation factor is fitted
between the underfloor-convector and surroundings, all
the way around and at the base, e.g. edge insulation
strips or sound insulation.
Installation
Remove packaging and check the delivery contents
(Fig. 2):
•
Underfloor-convector
–
for adjusting screws and screw latches (quantity
depends on size of the underfloor-convector, re-
fer to technical data)
–
with preinstalled plastic protective molding for
strips
•
Linear grate/rollout grate (if ordered)
•
Installation cover made from wood, 2- and/or
3-part
•
Installation instructions
Remove linear grate/rollout grate and pack for sto-
rage, until it is finally positioned.
Note
Special feature wooden roller grates
Wood is a natural product and is constantly chan-
ging due to heat, humidity and dryness. This may
also result in a change in dimension, such as
Shrinking, the wooden rods used lead and thus to
a change in length of wooden roller grates.
Growth, color, texture and grain can vary.
Note
Damage to the linear/roll-up grids due to incor-
rect handling!
Do not subject roll-up grids to point loading, e.g.
involving chair/table legs or ladders.
When rolling up the troll-up grids make sure that
the internal tension spring is not overstretched or
kinked.
If desired, attach suitable insulation all around and
on the bottom (Fig. 3).
Remove the installation cover completely.
Align the underfloor-convector with respect to po-
sition and height on all adjustable screws (Fig. 4).
Fix all screw latches in place with screws and do-
wels. Turn the front screw latches inward 45°±10°
(Fig. 5-7).
Connect heating circuits and, if necessary, cooling
circuits corresponding to the connection-situation
(Figs. 8-10d). The connection set is optional, shown
by dotted lines and only hand-proof preassembled.
3/4"- counter connection screws, do not twist.
With KRN92: connect supply air (Fig. 11). The sup-
ply air can be positioned or locked on the valve in
the interior of the underfloor-convector.
With KC261/KC461/KC291/KC491: connect conden-
sate drain (Fig. 12).
Underfloor-convectors having electrical compo-
nents: electrical connection can be carried out by an
electrician after separate instruction.
Activate the underfloor-convector and ventilate.
Carry out leak testing.
If the system is tight, raise the installation cover
(Fig. 13).
Before completion of the flooring, make sure that
the underfloor-convector is correctly oriented. No
height adjustment is possible after the flooring
work.
Danger
Overheating hazard!
Do not operate the underfloor-convector with the
installation cover in place.
Final work (Fig. 14)
If the construction work is finished:
Remove the installation cover.
Remove plastic protective molding for edge strips.
Put linear grate/rollout grate in place.
