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
VP 18 EK is a ventilation unit with heat recovery. The unit can yield up to 325m3/h at 100Pa exter-
nal back pressure. The energy in the exhaust air is being transferred to a 180L hot-water tank via a
heat pump. When the water is heated the remaining energy is being transferred to the supply air.
The unit is delivered with a G4 filter. In addition to this the unit can be equipped with different ac-
cessories e.g. hygrostat and filter box with pollen filter.
Operating the unit is done with the 600 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.)
VP 18 EK is delivered in a white-lacquered aluminum-zinc cabinet, tested and ready for use. Instal-
lation and start-up must be carried out by an authorized electrician.

Power supply

Power supply including safety switch must be installed by an authorized electrician.
The VP 18 EK -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.)
The built-in sensor of the panel prevents further cooling of the building in case of outage of the
primary heating source. Should the panel sensor detect a temperature below the set value, the
ventilation system will stop. (Factory set position is 10 °C, can be set to anything between 1 and 20
°C)

Assembly of VP 18 EK

When mounting the VP 18 EK -unit future service and maintenance should be consid-
ered. There is required a minimum of open space in front of the unit of 600mm measured
from the front of the unit.
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 unit should be leveled on a firm and vibration free bed. There should be at least 30mm to
building components and other inventory. The unit itself is quiet and almost vibration less; still any
potential vibration should be taken into account.
It is important to establish a condensation drain from the unit to the outlet. The unit has an inte-
grated water seal. The drain should be carried frost-proof and even downgrade to the outlet. The
overflow from the safety valve should also be carried to the nearest outlet.
If there is made a covering above the unit it should be easy to remove for maintenance purpose.
