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!

Different versions of CTC Condensation drain

CTC Condensation drain is available in three lengths. Here you can see an example of the installation length.

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.

Drain indoors

Water seal

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.

routing inside house not included.

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.

All electrical connections must be carried out

by an authorised electrician.

CombiAir

CTC Condensation drain connects to the communication

board (AA23-X1:4-6) in CombiAir. Communication board
