DELIVERY SET
The fan design is constantly being improved, so some models can slightly differ from those ones
described in this manual.
The VP ceiling fan in a metal casing with 100, 125 and 150 mm exhaust outlets (hereinafter
"Fan") is intended for ventilation systems of industrial or residential buildings, swimming
pools, blocks of flats, offices, hospitals, restaurants and other spaces heated during the winter.
The air discharged by the fan must not contain dust, solids, sticky substances and fibrous
materials.
The ambient air temperature must not exceed the limit values given in Table 2.
The fan is designed for installation between the floor slab and the suspended ceiling attached
to the ceiling structure on mounting brackets or to a wall on side mounts (VP 100 and
VP 125 only).
The fan is designed for extended periods of continuous operation without disconnection
from power mains.
The products meet the requirements of IPX4 hazardous parts access and water ingress
protection standard.

SAFETY REQUIREMENTS
Disconnect the fan from power mains prior to any installation, setup, maintenance and repair
operations.
The fan must be connected by an expert qualified for unassisted operations with electrical
installations up to 1,000 V after being made familiar with the present technical certificate.
Prior to installation check for any visible damage to the impeller, casing and grille.
Also check the casing flow channel for any foreign objects which may damage the impeller
wheel blades.
The fan may only be used as intended. No modifications or alterations are allowed.
The fan is not intended for operation by children or any persons with reduced physical, mental
or sensory capacities, lacking practical experience or knowledge unless controlled or briefed
on the device operation by the person responsible for their safety.
The fan may not be used to handle air containing highly flammable substances or vapours
such as alcohol, petrol etc.
The fans take 230 V 50/60 Hz single-phase alternating current.
Children being supervised not to play with the appliance!

The VP ceiling fan (Fig. 2) comprises of casing 1 with lid 2.
The casing has an exhaust outlet 3 with a check valve
which prevents back flow of air while the fan is off.
Terminal box 4 containing the terminals for
connecting the fan to power mains is mounted
to the casing. Grille 5 with air filter 6 is attached
to the casing with screws.
Decorative front panel 7 locks into the slots on grille 5.
The casing houses a single-phase electric motor
with a centrifugal impeller and backward-curved
blades. The electric motor has integrated thermal
protection and restarts automatically.
The replacement of parts of the safety suspension
system device shall be performed by the
manufacturer, its service agent or suitably qualified
persons!

INSTALLATION AND OPERATION INSTRUCTIONS
The fan is installed between the floor slab and the suspended ceiling by means of
two mounting brackets. The distance between the bracket attachment point and the
suspended ceiling must be within 165 - 390 mm.
The fan installation steps are given in Fig. 5, 6.
The power is supplied via an external terminal box mounted to the fan casing.
WARNING: If unusual oscillating movement is observed, immediately stop using the
ceiling fan and contact the manufacturer, its service agent or suitably qualified persons!
The fan is to be installed so that the blades are more than 2.3 m above the floor!

Disconnect the damper from the power supply (electric mains) prior to any work on the unit.
Power mains connection shall only be performed by a qualified electrician.
The nominal electrical parameters of the fan are given on the manufacturer's label.
Any tampering with the internal connections is prohibited and will void the warranty.
The fans take 230 V 50/60 Hz single-phase alternating current.
The fan connections (cables and wires) must be durable, insulated and heat-resistant.
The external lead-in (230 V 50/60 Hz) must be equipped with an automatic circuit breaker
built into the stationary wiring to disconnect all the mains phases.
The location of the QF external switch must ensure unobstructed access for shutting down
the fan quickly if required.
The protection trip current must be consistent with the current consumption of the fan.
The recommended nominal current of the automatic cutout switch is 0.6 A,
2
the recommended minimum conductor cross-section is 0.5 mm .
The conductor cross-section values are given for reference only while the actual selection
must be based on the maximum permissible wire heating which depends on the wire type,
its insulation, length and installation method (i.e. overhead, in pipes or inside the walls).

TECHNICAL MAINTENANCE
STORAGE REGULATIONS
The technical maintenance of the fan includes periodic cleaning of the fan surfaces from
dust and dirt.
The filter must be replaced on a need-to-do basis, but at least every 6 months.
The impeller cleaning and filter replacement steps are given in Fig. 9.
The impeller blades must be thoroughly cleaned from dust and dirt every 6 months.
The fans must be stored in the original packing in a well-ventilated area at temperatures
from +5 °C to +40 °C and relative air humidity up to 80 % (at Т= +20 °C).
