Introduction

Please control that the following documents have been delivered together with the unit:
- Directions for assembly & use (this document)
- CTS 602 directions
- Electrical chart
Should you have any questions on how to operate the system, contact your nearest Nilan dealer,
who you can find at www.nilan.dk/dealers
Combi 302 Polar is a combined passive and active heat recovery plant with a cooling function.
The standard delivery of the Combi 302 Polar is with filter classes F5 (EU5) in the exhaust device
and F7 (EU7) in the injection.
The unit can be equipped with different accessories e.g. hygrostat and filter box with pollen filter.
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.)
For accessories see page 23.

We recommend that the system as well as the installation is adjusted/checked to ensure
a healthy indoor climate and optimal operation.

This document may be subject to change Side 4 of 24
Power supply

Power supply including safety switch must be installed by an authorized electrician.
The Combi 302 Polar 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°C to 20°C.)
Use of t he CTS 600 panel :

Figure 1: CTS 602 control
If a water post-heating element is installed, the control valve and circulation pump must be elec-
tronically connected as described in the provided wiring diagrams.

Assembly of Combi 302 Polar

When mounting the Combi 302 Polar future service and maintenance should be consid-
ered.
It is recommended to have minimum 60 and 30 cm free space in front of-
and at the end
of the plant.
The system must be level due to the condense outlet. The condense outlet requires a clearance
height of minimum 11.5 cm under the outlet connection piece.
It is not necessary to re-insulate the system as it is delivered with a 20 mm standard insulation.
The system is low-noise and low-vibration. However, potential vibrations spreading from the sys-
tem to the individual building parts must be taken into account. We recommend a minimum
distance of 30 mm from building parts and other fixtures. It is recommended to place the plant on
vibration absorbers to separate the plant and the base

Condensation drain / water seal
The Combi 302 Polar 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 1 cm per
meter, 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.
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. This means that the first bend of the water seal must be at least twice as long in order for
the system to be able to dispose of the condense water (see figure 3).
The condensation drain must be airproof from the unit to the water seal in order for the condensa-
tion water to be let away from the unit. If the condensation drain is not airproof false air will be
sucked in to the unit and the water will stay inside the unit.
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.

Figure 3: Condensation drain / water seal

The water seal should be tested as described below. (the unit must be connected to the
ducting and the front door should be closed):
The condensation tray is filled with water and the unit is started at the highest ventilation
step. The unit should run for a couple of minutes. Check that the condensation tray is
empty when the test is finished.

Ducting
We recommend that there are used ducts and fittings with rubber packing that meet sealing class
B and that the connections between the unit and the ducting are made with 1 metre sound absorb-
ing flexible transitions as regards sound reduction.
The ducts should be shortened with a hacksaw or an angle grinder and laid out according to the
working drawing. The ducts are typically laid out on the main beam of the truss frame and are se-
cured with hole belts or they are being hanged in assembly belts. Please avoid any unnecessary
area reductions and breaks of the ducting.
The ducts should be insulated – in some cases with the ordinary attic-insulation. All ducts should
be insulated with 100mm mineral wool to avoid heat loss and condensation. This also applies for
flexible transitions. It is recommended that the insulation is carried out with 2 layers of 50mm. If the
ducts are laid out in an unheated room it will cause condensation problems if the unit are turned off
for a longer period of time as the hot air from the heated room will rise to the ducts and cause con-
densation which can cause damp problems.
Figure 4: Insulation of ducting
The discharge duct is leading the exhaust air away either above the roof or through the outer wall.
It is important that the roof cowl has at least the same open space as the duct leading to the roof
cowl. A reduction at this place will cause an unnecessary pressure drop which can lead to a re-
duced ventilation output.
The holes for the inlet- and exhaust valves should be cut according to the mounting-frame for the
prescribed valve. The frame for the valve must be secured with screws before placing the valve in
the frame. The valves are placed in accordance with the size, construction and use of the room. As
an example we would not recommend placing an inlet valve just above people with sedentary work
because the inlet air in some cases would be experienced as a draught.
