General information before installation

Check that the following documents have been supplied with the unit:
- Installation Guide (this document)
- CTS 602 User Guide
- Wiring diagram
If you have any questions concerning installation after reading the guide, please contact your
nearest Nilan dealer via www.nilan.dk/dealers
The unit is designed for installation of supplementary heating elements (electric or water) for addi-
tional heating of inlet air.
The unit is supplied as standard with filter classes F5 (EU5) for exhaust and F7 (EU7) for inlet air.
The unit is operated by a CTS 602 control system, featuring a wide range of functions, e.g. menu-
controlled operation, weekly programme, filter monitor with timer, adjustment of fan speed etc. CTS
602 is described in a separate user guide supplied with the system.
For spare parts and other accessories, see page 24.

Electrical installation

Electrical installation/power supply (including safety switch) must be installed by an au-
thorised electrician.
Connect the unit according to the wiring diagram supplied.

Each ventilation part must be connected to mains electricity before the unit can be start-
ed.
The unit is supplied with a 1m test cable for the CTS 602 panel. The panel is connected to the CTS
602 control system in the unit by cable type 2 x 2 x 0.25 mm2 twisted pair (max. length 50 m).
The CTS 602 panel must be placed in a dry, frost-free place. The integrated sensor prevents fur-
ther cooling of the building in the event of breakdown of the primary heating supply, by stopping
the ventilation unit if the panel sensor goes below its set value. (factory set at 10°C, can be set
between 1°C and 20°C).
Figure 1: CTS 602 control panel
If an electric or water heating element is fitted in the unit, the regulation valve and circulation pump
must be connected according to the wiring diagrams supplied.

Setting up VPM

During set up, future service and maintenance should be taken into account.
We recommend a minimum gap in front of/behind the unit according to N/M, O/P -
measurements (see Figure, page 23).
The individual nozzles are labelled to simplify setting up. Please note the attached labels. The noz-
zles and duct system are connected by flexible pipes (flex-pipes, sound-insulated flex-pipes or
other type).
A non-return damper should be fitted to prevent condensation, frost and heat loss. Dampers can
be controlled via the CTS 602 control system.
The unit must be installed level for the sake of the condensation outlet. The condensation outlet
requires clearance of min. 120 mm under the drain nozzle.
No additional insulation is required, as the unit is supplied with 50 mm of insulation as standard.
If installed outdoors, the unit must be covered (above its top at the least) to prevent water getting
in.
Although the unit generates practically no noise or vibration, measures should be taken to prevent
vibration radiating into the building. To separate the unit from the surface it stands on, we recom-
mend placing it on vibration dampers.

Condensation outlet/water lock
VPM models are supplied with a 20 mm condensation outlet (PVC, GF fittings). The drain is locat-
ed under the discharge air nozzle. The unit is supplied with a fitting in front of the drain for
protection during transportation. Remove the fitting before fitting the water lock.

A water lock is required connected to the condensation outlet. A pipe with a consistent
fall of at least 1 cm per metre must connect the condensation nozzle to the nearest
drain. Protect the pipe from frost.

It may be necessary to fit a heating cable to the condensation outlet to prevent icing,
running from the unit to the house climate screen. The electrician is responsible for pro-
tecting the condensation outlet from frost.
There can be underpressure of up to 500 Pa (= 50 mm water column) in the drain during operation.
The height difference in the water lock must therefore be minimum 50 mm. The first bend in the
water lock must be at least double the length to ensure flow of condensate water.
The condensation outlet must be airtight from the unit to the water lock to ensure unobstructed flow
of condensate water away from the unit. If the condensation outlet is not airtight, air will be drawn
in and the water will not flow away from the unit.
The water lock can dry out and prevent water from draining from the condensation tray. It should
therefore be checked regularly, and topped up with water as required. Filling the water in the lock
above the minimum requirement will reduce the need for topping up.

Figure 3: Installing water lock

Once the water lock is installed, test its function as follows (the unit must be connected
to the duct system, and covers in place):
Fill the condensation tray with water. Start the unit at highest fan speed with the doors
closed. Allow the unit to run for a few minutes. Check there is no water in the condensa-
tion tray when the test is concluded.

Heating element, water (option)

Connection of the heating element must be performed by an authorised plumber.

If the unit is installed outdoors, or outside the building's climate screen, protect the in-
stallation against frost damage.
The heating element is installed inside the unit by the factory if ordered as an option. If retrofitting a
water heating element, it must be activated in the CTS 602 control system as described on page
13.
Pass the pipe connections to the element through the inlet nozzle side. It is important that the
pipes are supported from the element where connected. See figure for recommended mixing loop.
Connect, bleed and check the system for leaks. The unit can then be started.
Check and clean the dirt trap after flushing the system.

The distance between the water circulation system and heating element should not ex-
ceed 2 metres to ensure stable adjustment of the element.
Avoid installing pipes in the unit such that the fan cannot be removed.

IMPORTANT, ref. Danfoss Actuator type AME 140:
Refitting the actuator MUST be performed as follows:
1. Disconnect mains electricity and remove the actuator cover.
2. Release the gear by depressing the button under the housing whilst screwing the shaft up-
wards (counter clockwise) as far as it will go.
3. Fit the actuator and connect electricity.
4. DIP switch no. 1 switch to ON and then to OFF.
5. Calibration will run automatically for up to 6 minutes.
(Diode will flash during calibration and then be constantly lit).
6. Fit actuator cover.
Permissible ambient temperature for Danfoss Actuator type AME 140/24 V is 0 ° C to 55 ° C.
Actuators are IP42 and therefore not suitable for mounting in the open.

Heating element, electric (option)
The electric heating element is installed by the factory if ordered as an option. If retrofitting an elec-
tric heating element, it must be activated in the CTS 602 control system as described on page 13..

The electric heating element must be connected by an authorised electrician.

Air exchange
The air exchange menu can be used to set 4 ventilation steps (air volumes) for the unit. Inlet air
and exhaust air can be set individually for each ventilation step.
A minimum ventilation step can be set for inlet, and min./max. ventilation steps for exhaust.
A delay can be set from when the unit switches on until the fan starts, to give the non-return damp-
er time to open.

Max. capacitor temperature can be adapted to the
ventilation system:
Cooling operation:
If the high pressure switch falls out, the "Max 55°C" is
lowered to for example 50°C.
At reduced cooling performance due to the hot gas
bypass the "Max 55°C " is raised to 57-60°C.
By high pressure failure the temperature is reduced. Min. time (in minutes)
where the compressor
must be stopped before
restarting.
