3Table of Contents |CTC Condensation drain

The accessory CTC Condensation drain is used to safely
divert most of the condensation from the air/water heat
pump to a frost-free collection point.
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
positioned so that it can cause damage to the
house.
The heating cable starts automatically at an outdoor
temperature of 1.5 °C. When the temperature exceeds
2 °C the heating cable switches off again.
NOTE
The installation of CTC Condensation drain can
affect the machine’s function. Read the entire
manual!

5Chapter 1 | GeneralCTC Condensation drain

General
Connect CTC Condensation drain 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 condensa-
tion water; to an indoor drain (subject to local rules
and regulations), stone caisson, gutter drainage or
other frost free collection point.
■When casting the base, the holes for CTC Condensation
drain must have an internal diameter of 110 mm.
■Route the pipe downward from the air/water heat
pump.
■The insulation of CTC Condensation drain must seal
against the bottom of the product's condensation
water trough.
■The drain from CTC Condensation drain must be posi-
tioned at frost free depth or indoors (subject to local
rules and regulations).
■The drain from CTC Condensation drain 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.

Joint
The condensation water is lead to an indoor drain (sub-
ject 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.

depth
If the house has a cellar the stone caisson must be posi-
tioned so that condensation water does not affect the
house. 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 illus-
tration.

Cable routing
The following image shows recommended cable routing
from distribution box to condensation water pipe. Route
the heating cable (EB14) through the grommet under-
neath and secure with two cable ties at the electrical
connection. Transfer between electrical cable and heat-
ing cable must occur after the lead-in to the condensa-
tion water pipe.
1. Remove the front and side panels.
2. Remove the rear cover plate from the stand.

3. Pull off the protective paper and secure the gasket
to the condensation water connection, see image.
4. Thread hose clamp on.
5. Route the heating cable through the condensation
water pipe.
6. Route the heating cable through the drain pipe on
the connection plate, see image.

7. Pull the insulation down slightly, connect the hose
to the drain pipe and tighten the hose clamp, as il-
lustrated.
2.
8. Push the insulation up towards the trough and se-
cure it using cable ties, see image.
3.
9. For CombiAir 6, screw the connection piece securely
to the stand as illustrated using a screw and washer.
Now clamp the gasket between the adapter and the
bottom of the module.
For CombiAir 8/12/16, loosen the nut and remove
the washer securing the heat pump module to the
stand. Fit the holder to the module’s foot and rein-
stall the washer and nut. Now clamp the gasket
between the adapter and the bottom of the module.
When the drain holes have been adjusted above one
another, tighten the nut.

10. Stretch the heating cable and ensure that the
marking on the heating cable is as close to the drain
pipe as possible.
