Introduction

Please control that the following documents have been delivered together with the unit:
- Directions for assembly & use (this document)
- CTS 600 directions
- Electrical chart
Comfort is designed for heat recovery with air volumes up til1200m3 / h. The energy from the ex-
haust is recovered to the inlet via the counter flow heat exchanger, where the two air streams pass
each other without coming into direct contact.
The system is prepared for retrofitting of a post-heating element (electricity or water) for supply
heating of the inlet air. The post-heating element is controlled via CTS 602.
The system comes standard with filter class F5 on the extract air and F7 on the supply air.
Operating the unit is done with the CTS 602 control. The control has many functions such as menu
based attendance, week programme, time controlled filter guard and adjustment of the velocity of
the ventilator. (Directions for the CTS 602 control is described in another document delivered with
the unit.)
Comfort is delivered tested and ready for use. Installation and start-up must be carried out by an
authorized electrician.

Nilan reserves the right to alter these instructions without prior notice Page 4 af 25
Power supply

Power supply including safety switch must be installed by an authorized electrician.
The Comfort-unit must be connected according to the attached electrical chart.
The unit is delivered with 1m test cable for the CTS 602 panel. The panel should be connected to
the CTS 602 control in the unit with cable type 2x2x0.25mm2twisted in pairs. (Maximum length
50m).
The CTS 602 panel must be placed dry and frost-proof. The panels’ integrated feeler prevents fur-
ther cooling of the building if the primary heat-supply stops by stopping the ventilation if the panel
feeler gets below a specific value. (Factory setting is 10°C; the value can be set from 1-20°C.)
CTS 602 control
If a water heating element is installed in the system, the regulation vent must be connected electri-
cally as described in the enclosed wiring diagrams.

Assembly of Comfort

When mounting the Comfort-unit future service and maintenance should be considered.
There is required a minimum of open space in front and behind of the unit of 60cm.
In order to ease the mounting each of the connection pieces is labeled. Please notice the labels.
The connection between the unit and the ducting should be a flexible transition.
The system must be level because of the condense outlet. The condense outlet requires a mini-
mum clearance height of 125mm beneath the outlet connection.
The exchanger is low-noise and low-vibration. However, potential vibrations spreading from the
system to the individual building parts must be taken into account. To detach the system from the
floor, we recommend that the system is placed on vibration absorbers. The vibration absorbers
must be placed diagonally on each corner to ensure that the system does not “fall down” from
them. If a water heating element is installed in Comfort 300/450/600, a clearance distance of 60cm
is required behind the system.
It is not necessary to re-insulate the system as it is delivered with a 20mm standard insulation.

Condensation drain / water seal
The Comfort unit is delivered with a 20mm condensation drain. (PVC, GF-fittings). The drain is
placed under the discharge.

The condensation drain should be carried with an even inclination of at least 1cm per
metre, frost-proof to the nearest outlet. The overflow from the safety valve should also be
carried to the nearest outlet.

To avoid frost problems it can be necessary to supply the condensation drain with a
heating cable. It is the plumbers’ responsibility to secure the drain. (See Accessories)
When the system is running, there can be a vacuum of up to 500Pa (corresponding to 50mm water
column) in the outlet. For this reason, the difference in height in the water seal must be minimum
50mm.
The water seal can dry out and avoid the water from running out of the unit. Therefore the water
seal should be tested regularly and refilled with water if necessary. An elevated height of the water
seal will reduce the need for refilling with water.

Heating surface, water

Connecting the heating surface must be done by an authorized plumber.

If the unit is placed outside or in a cold location the installation must frost secured.
The heating surface should be connected, scavenged and checked for any leakages before start-
ing the unit.
The dirt-catcher should be checked and cleaned after a thoroughly flushing of the system.

To obtain a stable control of the heating surface, the distance between the mixing loop
and heating coil must not exceed 2 meters.
Avoid routing pipes in the system in such a way that the fan cannot be removed.

IMPORTANT regarding Danfoss Actuator type AME 140:
Re-installing the actuator must be done as described below:
1. Disconnect the power supply and remove the cover of the actuator.
2. Liberate the gear by pressing down the button as the spindle is turned up (counter clock-
wise)
3. Re-install the actuator and turn on power.
4. DIP-switch nr. 1 should be moved to ON and then to OFF.
5. The actuator is automatically calibrating for up to 6 minutes.
(The LED is flashing when calibrating and is lit constantly when finished).
6. Re-install the cover of the actuator.
The actuator should be placed in an environment of 0°C to 55°C.
