Unit type
Product description
The VPR 120-560 series is a ventilation and heat recovery unit with cooling and heating functions developed especially for commercial
properties
with an air exchange of up to 6,600 m? per hour.
Heat recovery takes place primarily via a high-efficiency rotary heat exchanger. It can be supplemented with the integral heat pump
to ensure that the supply air gets heated up so the user does not experience a draught during ventilation.
The reversible heat pump can reverse the cooling circuit so it cools the supply air in the summer and helps ensure a comfortable
indoor climate that is not too hot.
The software in the CTS602i control system ensures that the rotary heat exchanger and the heat pump work together to achieve the
greatest
effect and to keep energy consumption at a very low level.
The evaporator and the condenser are located on both sides of the rotary heat exchanger. This gives you the full benefit of the perfor-
mance of the heat exchanger in both heating mode and cooling mode. The result is a high heating and cooling effect.

Shut-off damper
CO2-sensor
Humidity sensor
You will need to order an after-heating element if, for instance, you want to use the ventilation unit for heat-
ing the building.
The electrical after-heating element is installed in the ventilation unit at the factory.
You will need to order an after-heating element if, for instance, you want to use the ventilation unit for heat-
ing the building.
The water after-heating element is installed in the unit at the factory and it comes with a 3-way valve and
a Danfoss Actuator.
Shut-off damper for external mounting comes in a pack of 2 together with 230V damper motors.
If the unit is to be installed outdoors, the damper motors should be fitted with a cover with protection rating
IP55
(not supplied by Nilan).
If you want the ventilation level to regulate in accordance with how many people are in the building, you can
order a unit with an integral CO2-sensor.
On the control panel you set the CO2-level you want. If this level is exceeded, ventilation will increase to the
set fan speed level.
If you want to regulate the fan speed level in accordance with the humidity level in the extract air, you can or-
der a unit
with an integral humidity sensor.
The unit can change the fan speed level to low or high humidity level.

15
Pressure control
Pressure-controlled filter alarm
Water trap with ball
Vibration absorbers
Handle with cylinder lock
Top cover
The motor for the extract and/or supply air fan can be controlled by one or two pressure transmitters. These
should be mounted in the extract and/or supply air duct.
The standard version is delivered with pressure transmitters and a 5 m cable, including power supply.
As standard, the control system has a time-controlled filter alarm that can be set between 30 and 360 days.
If you want an accurate indication of when to change the filter, we recommend that you order
a pressure-controlled filter alarm. It displays the pressure drop over the filters in the CTS control system reg-
ularly. You preset a final pressure drop in the control system, and an alarm will indicate when this pressure
drop has been reached and the filters need replacing.
A regular water trap could potentially dry out. If this happens, the water trap stops working, air is drawn into
the ventilation unit, and condensate water cannot drain away via the condensate drain. Condensate water
will then leak from the unit onto the floor and potentially cause damage.
We therefore recommend that you install a water trap with ball to ensure that the condensate drain always
works. Should the water trap dry out, the ball will prevent air from being drawn into the system, and conden-
sate water will drain away freely.
Vibration absorbers (sylomer pads) ensure that vibrations from the unit to the underlying surface are damp-
ened effectively. The vibration absorbers are placed under the unit.
If you want to be able to lock the service doors to the unit, you can purchase handles with a cylinder lock and
key.
If the unit is to be installed outdoors, you can order a top cover for protection against rain and snow.

16
Extension cable HMI user panel for 8-pole plug
The user panel for the ventilation unit is connected to a short cable so that it can be mounted near the unit.
The panel can also be mounted on the front of the unit.
If the unit is located in a place where you cannot immediately see the user panel, e.g. in a technical room or on
a ceiling, you can order a 10 or 20 m extension cable with connectors so that the user panel can be placed in a
place where the user can see it.
It is important that the user panel is placed so that the user can see any alarms such as filter alarm.

17
Installation
Handling
Unwrapping
The unit is delivered wrapped in foil. In order to protect the galvanized sheets on the unit from discoloration, immediately remove the
foil. You may consider covering the unit with tarpaulin until installation.
Transport after unwrapping
When you are going to position and install the unit, you can transport or move it in two different ways:
• Lifting the unit from underneath with a pallet truck. Units with a pre-mounted foundation can be lifted directly with a pallet truck -
take care NOT to damage the base feet.
• If you are lifting the unit using ropes/straps, the base angles must be more than 60°.If this is impossible due to a lack of space, a lift-
ing beam or similar must be used.
Min. 60° Lifting beam
ATTENTION
Visible transport damages must be reported immediately. Hidden transport damages must be reported within 7 days of
delivery. When reporting transport damages, photo documentation is required.
Please see Incoterms 2010 for terms of delivery, warranties, limitation periods and compensation limits etc.

18
Installation
Positioning the unit
Leave plenty of free space in front of the unit (see table).
When positioning the unit, you should always consider future service and maintenance. You have to be able to replace filters easily as
well as fans and other components. There has to be enough room for you to clean the unit easily. When cleaning the unit, water may
leak from the condensate drain. There must therefore be enough space to install a water trap in connection with the condensate drain.

ATTENTION
It is important that the unit is installed in level to obtain a proper drain from the condensate tray.
ATTENTION
Even though the unit is quiet and has low vibrations, you should still take vibrations into account. To create separation
between the unit and the base, it is therefore recommended to install vibration dampers under the unit.To other build-
ing parts there should be approx. 10 mm distance.

Positioning and installing the unit
Outdoor installation
When installing the unit outdoors, the required level of storm protection depends on how exposed the unit is. It is the responsibility of
the installer to ensure that the unit is adequately secured.
When installing a unit outdoors, it is recommended that you purchase a top cover to protect the unit against the elements.
Step 1
Position the unit exactly on the allocated spot.
Step 2
Place a Sylomer vibration damper under each end of both base
feet.
1. Nilan base foot
2. Vibration damper (Sylomer)
Step 3
Check the unit is level.
