VN VN

To install KP 80 casing:

6.1. Perform operations 5.1 and 5.2;
6.2. Arrange a recess in the shaft wall for the fan casing (Fig. 21);
6.3. Connect an air duct to the fan outlet fitting;
6.4. Prior to casing installation make sure that the fire-retarding spring-loaded back valve in KP 80
casing to be installed into the recess closes under spring action at zero air pressure.
6.5. Mount KP 80 casing into the construction opening on cement grout.
Route the power cable through the sealed lead-in in the rear part of the casing.
The minimum cable length from the casing is 250 mm. (Fig. 64).
The casing can be also installed inside a wall or in the counterceiling recess using mounting
brackets (Fig. 22).
6.6. Following the installation cover the casing with the protective fiberboard plate to prevent
damage or accumulation of dirt on the casing during the interior finishing of premises (Fig. 54).
To perform final assembly of VNV-1 80 KV, VNV-1 80 KVK and VNV-1 80 KP fans:
7.1 On completion of interior finishing remove the protective plate and install VNV-1 80 fan assembly
(Fig. 60-61).
The grill design allows its adjustment relative to the casing while mounting the fan to compensate
for any misalignment (Fig. 62).
If KV 80, KVK 80 or KP 80 casings and VNV-1 80 fan assembly are supplied separately the fan disassembly
during installation is not required.
The remaining installation sequence remains unchanged.
