KVR 10Chapter 1 | Important information4
Important information
The accessory KVR 10 is used to safely divert most of the
condensation from the air/water heat pump to a frost-free
collection point.
The accessory is suitable to following products from NIBE:
•• F2050F2016
• •F2026 F2300
•• NIBE SPLIT HBS 05F2030
• •F2040 NIBE SPLIT HBS 20
NOTE
It is important to the heat pump function that
condensation water is led away and that the drain
for the condensation water run off is not posi-
tioned so that it can cause damage to the house.
The heating cable starts automatically at an outdoor temper-
ature of 1.5 °C. When the temperature exceeds 2 °C the
heating cable switches off again.
NOTE
The installation of KVR 10 can affect the machine’s
function. Read the entire Installer Manual together
with the main product’s Installer Manual!
Different versions of KVR 10
KVR 10 is available in three lengths. Here you can see an example of the installation length.

General
Connect KVR 10 to the heat pump's condensation water
trough using the supplied hose clamp.
•Pipe installation must be carried out in accordance with
current norms and directives.
•We recommend three ways of leading off condensation
water; to an indoor drain (subject to local rules and regu-
lations), stone caisson, gutter drainage or other frost free
collection point.
•When casting the base, the holes for KVR 10 must have
an internal diameter of 110 mm.
•Route the pipe downward from the air/water heat pump.
•The insulation of KVR 10 must seal against the bottom of
the product's condensation water trough.
•The drain from KVR 10 must be positioned at frost free
depth or indoors (subject to local rules and regulations).
•The drain from KVR 10 must be able to receive up to
100 litres of condensation water per day.
•The installation must be equipped with a water seal where
air circulation can occur in the condensation water pipe.
Drain indoors
Water seal
The condensation water is lead to an indoor drain (subject
to local rules and regulations).
Route the pipe downward from the air/water heat pump.
The condensation water pipe must have a water seal to
prevent air circulation in the pipe.
Pipe routing indoors is not included.
NOTE
Do not select this option, "Indoor drain", if you have
an air/water heat pump with a flammable or easily
combustible refrigerant.

depth
If the house has a cellar the stone caisson must be posi-

Otherwise the stone caisson can be positioned directly under
the heat pump.
The outlet of the condensation water pipe must be at frost
free depth.
Gutter drainage
NOTE
Bend the hose to create a water seal, see illustra-
tion.

Cable routing F2016 / F2026
The following image shows the recommended cable routing
from distribution box to condensate drain pan in
F2016 / F2026. Transition between electrical cable and
heating cable must be as illustrated.
1. Remove cover.
2. Thread hose clamp on.
3. Route the heating cable through the condensation water
pipe.
4. Remove the condensation water trough.
5. Route the heating cable through the condensation water
connection and lead-in.
6. Pull the insulation down slightly, connect the hose to
the condensation water connection and tighten the
hose clamp.
7. Push the insulation up towards the trough and install it
using cable ties.
8. Lay the heating cable so that the marking is as close to
the condensation water connection as possible.
9. Route the cable to the distribution box as illustrated.
(Extend the cable so that removal of the condensation
water trough is possible, i.e. with some margin.)
10. Use factory fitted cable tie.
11. The distance between the distribution box and the lead-
in to the condensation water trough is approx.
2,000 mm.
12. The length of the non heat conducting section of the
cable needs adjusting. Roll the cable to the correct
length (do not cut).
13. Connect the cable according to the "Electrical connec-
tion" image. (Check fuse according to table. See Fuse
page 11.)
14. Reinstall the condensation water trough and cover.
NOTE
Ensure that the marking on the cable is edge to
edge with the drain (see image).
NOTE
Do not cut the heating cable!

Cable routing F2040
The following image shows recommended cable routing
from the electrical connection to the condensation water
pipe. Route the heating cable (EB14) through the grommet
on the underside and secure with two cable ties at the
electrical connection. There is a transition between the cold
and hot sections of the heating cable at the marking on the
cable. The marking has to be edge to edge with the hole for
the cable grommet.
1. Remove the front and side panels.
2. Remove the rear cover plate from the stand.
