Disconnect the product from the power mains prior to all operations
specific to connection, setup, maintenance and repair.
Fan maintenance and installation shall only be performed by professional
electricians qualified for unassisted operations with electrical installations
up to 1000 V after careful study of the present manual.
All the fans are not designed for out-of-the-box operation and require
connection to the air ducts.
The ducts are connected to the fan on both sides.
If the fan is mounted outdoors it should be protected against the elements
and moisture (e.g. by means of a top hood above the fan).
Prior to connecting the fan to the power mains check for visible damage
of the casing and any foreign objects in the fan casing which may damage
the impeller blades.
The fan may only be used as intended. No modifications or alterations
are allowed. The fan is not intended for operation in areas with an explosive
and/or chemically aggressive environment.
Take all the reasonable steps to prevent back draft of gas from any units
which utilize gas or direct flame.
The fan is rated for connection to single-phase ac 230 V / 50 Hz and
three-phase 380/50 Hz power mains.
Prior to the fan installation check the integrity of the power supply wires
and for any obstructions to the impeller wheel.
It is recommended that flexible inserts are mounted on both sides of the fan
upstream and downstream.
Mount the fan in such a way that the arrow on the fan casing matches the
air flow direction in the system.
The fan requires reliable grounding.
SAFETY REQUIREMENTS
INSTALLATION AND OPERATION INSTRUCTIONS

The fan casing is made of galvanized steel soundproofed on the inside
with 50 mm thick mineral wool.
The pivot design of the swing-out motor-impeller unit ensures easy
access to the fan internals for quick and efficient cleaning.
The inlet and outlet fitting diameters match the standard duct sizes.
The fittings have rubber seals.
The fan in mounted on RN-VRPK load-bearing frames with integral vibration
dampers and mounting brackets KM-VRPK (ordered separately).
The fan benefits from a steel high-performance centrifugal impeller with
forward-curved vanes.
The impeller is mounted on the electric motor shaft and is jointly balanced
statically and dynamically.
The high-performance single-phase or three-phase electric motor with a
squirrel-cage rotor is completely maintenance-free.
The power is adjusted by means of transformer control units.
The fan is connected to the power mains via the terminal box mounted
on the electrical motor.
Provide an additional electric cable length to ensure unobstructed
opening of the swing-out motor-impelle r unit.
Check the unpacked fan casing (no dents or deformations are allowed)
and make sure that the impeller has smooth rotation and does not touch
the flange and the casing.
Follow the safety regulations during the make-ready procedures and
operation.
Fig. 3 shows the fan wall mounting option using KM-VRPK mounting
brackets.
KM-VRPK mounting brackets are not included in the delivery package.
Ensure a direct air duct section of at least one air duct diameter long
on the inlet side and at least three air duct diameters long on the
outlet side.
The fans undergo continuous design improvement - therefore, some
models may slightly differ from those described in the manual.

Disconnect the fa n from the power supply prior to any work
on the unit.
All the electrical connections of the fan must be made by a qualified
electrician.
The nominal values of electrical para meters are given on the fan
manufacturer's label.
Any tampering with the internal connections is prohibited and will
void the warranty.
The power supply depends on the fan type: 230V/50 Hz single-phase or
380V/50Hz three-phase AC voltage.
The fan connections (cables and wires) must be durable, insulated and
heat-resistant.
The external lead-in (230V/50Hz or 380V/50Hz) must be equipped with
an automatic circuit breaker integrated into the stationary wiring.
The position of QF external switch must ensure free access for quick
power-off of the fan.
The recommended automatic breaker nominal current and conductor
sections are given in Table 3.
2
The power conductor section is 1.5 mm.
However, the conductor section selection shall account for the maximum
permissible wire heating which depends on the wire type, its insulation,
length and installation method (i.e. overhead, duct layout or inside the walls).
The trip current shall be consistent with the current consumption of the
unit as given in Table 2.
The fan connections shall be made on the terminal block mounted inside
the terminal box on the fan casing in strict accordance with the electrical
connection diagram and terminal designations.
The label with terminal designations is inside the terminal box.
The QF automatic switch is not included in the delivery package and is
installed by the user.
The fan wiring diagrams are given on Fig.4 and 5.
Connect the fan to the power mains as shown on Fig.6.
