INSTALLATION
The fan is designed for wall or ceiling mounting with direct air exhaust to the ventilation shaft or into the round air duct of

3.9. Rotate the fan and align the mounting holes of the casing and those of the swing damper, and secure the fan with self-
tapping screws (Fig. 44).
3.10. Complete steps 1.2 to 1.4. in the reverse order.
VN E 80 K fan installation steps:
4.1. Complete step 3.1.
4.2. Complete steps 2.2. and 2.4.
4.3. Complete steps 3.3. and 3.9.
4.4. Complete steps 2.2. to 2.4. in the reverse order.
VNV-1 E 80 KV, VNV-1 E 80 KVK and VNV-1 E 80 KP fans consist of VNV-1 E 80 fan assembly and KV 80, KVK 80 and
KP 80 fan casings correspondingly.
These fans are installed in two phases: first the casing installation and then the final installation:
- the casing is installed during the shell and core phase;
- the final installation, which is performed after the fit-out works, includes the installation of VNV-1 E 80 fan assembly into
KV 80, KVK 80 or KP 80 casing.
The KV 80 and KVK 80 installation steps are as follows:
5.1. Complete steps 1.2. and 1.4.
5.2. Remove the fan assembly from the casing (Fig. 45 and 46).
5.3. Bend the mounting bracket to the necessary length according to the actual wall measurements and secure it to the fan
casing with M4 screws supplied with the unit (Fig. 47-50);

17
EN
5.4. Route the power cable into the fan casing.
5.5. Fill the gaps between the fan casing and the wall opening with mortar, sealing foam etc.
5.6. Once the installation has been completed, cover the casing with the cardboard spacer to prevent damage or
contamination during the fit-out works in the space (Fig. 51).
To install KP 80 casing:
6.1. Complete steps 5.1. and 5.2.
6.2. Make a recess in the shaft wall for the fan casing (Fig. 21).
6.3. Connect an air duct to the fan outlet.
6.4. Prior to installing the casing make sure that the fire-stop spring-loaded backdraft damper of KP 80 casing to be installed
in the recess is properly closed by the spring in the absence of air flow.
6.5. Install KP 80 casing into the recess and fix it with mortar. Route the power cable through the gland in the rear side of
the casing. Allow at least 250 mm of cable from the casing. The casing can also be integrated into a wall or the ceiling using
mounting brackets (Fig. 22).
6.6. Once the installation has been completed, cover the casing with the cardboard spacer to prevent damage or
contamination during the fit-out works in the space (Fig. 51).
The final installation of VNV-1 E 80 KV, VNV-1 E 80 KVK and VNV-1 E 80 KP fans includes the following steps:
7.1 On completing the fit-out works in the space remove the cardboard spacer and install VNV-1 E 80 fan assembly (Fig. 53
and 54). The mountings allow fine adjustments of the grille angle relative to the fan casing for a level fit even if the casing is
misaligned (Fig. 55).
If KV 80, KVK 80 or KP 80 casing and VNV-1 E 80 fan assembly are supplied separately the installation does not require
disassembling the fan.
The rest of the installation steps remain unchanged.

18
EN
Before proceeding with the fan installation check the position of backdraft damper 2 which must close
under its own weight in the absence of air flow (Fig. 56). By default the position of backdraft damper
corresponds to the outlet connection to the right or upwards. If the outlet connection is pointed to the
left after the installation remove the backdraft damper from outlet pipe 1, turn the damper 180° and
insert it into the pipe.
For sectional air vents use rectangular-section steel ducts or SPIROVENT spirally wound air vents.
For air duct connections use ALUVENT or THERMOVENT flexible air ducts.
The nominal diameter of air duct connections is 80 mm.
If the connection air duct is concealed within a brick wall it should be wrapped with self-adhesive PVC
tape to prevent mortar-induced corrosion
