Dalap CECYL

Please read the instructions carefully. Pay particular attention to the operating
requirements.
Axial-flow duct electric fans of the combined type
Purpose
CECYL axial-flow duct electric fans are intended for use in ventilation systems of industrial, public, and
residential buildings. The duct funs are connected to round ducts.
Electric fans are designed to remove air and other non-explosive gas-air mixtures that do not contain
sticky substances and fibrous materials, with a dust and other solid impurities content of no more than
10mg/m³, at a temperature of transported air not lower than -20 °C and not above +40 °C.
Safety requirements
The fans are designed to be connected to an alternating current with a voltage of 220-240V and a
frequency of 50Hz. According to the shock-hazard protection type, the fans refer to Class II devices (for
models 100-200), Class I (for models 250-315), in accordance with GOST 12.2.007.0-75. The climate
category «moderately cold» Type «4» (УХЛ4) GOST 15150-69.The degree of
the fan protection against access to hazardous parts and water ingress is IP44 and the degree of the
motor protection is Ip44.
ATTENTION!
The fan should not be operated outside the specified temperature range (from +1 °C to +40 °C).
It is forbidden to install the fan in the same ventilation line with the smoke injector pipe from
devices with fuel burners.
ATTENTION!
• All work on installation and connection of fans should be carried out only with the mains voltage
removed.
• The fans shall be connected by electricians who have a special permit for the work performed.
Means for disconnecting from the mains supply should be built into the fixed wiring, in
accordance with the installation regulations. The disconnecting device should
disconnect all poles. The grounding conductor should not break.
• The device is not intended for use by persons (including children) with reduced physical,
mental capacity, or mental abilities or lack of experience or knowledge, unless they are
supervised or instructed to use the device by a person responsible for their safety. Children
should be supervised to ensure that they do not play with the device.

CECYL fan installation
Installation
CECYL fan is suitable for the following types of installation:
- on a wall, a ceiling, or a floor;
- for self-assembly or as a part of air ducts;
- for horizontal and vertical installation.
For horizontal installation, the length of the air duct should be at
least 0.5m; for vertical installation, a ventilation hood should be
installed to prevent moisture from entering the device.
In case of non-compliance with
these requirements, the IP44
degree will not be provided.
It is prohibited to install and to use CECYL fan with
the terminal box facing down.
The level of inclination of the CECYL fan terminal box
should not be lower than the central axis.

CECYL fan installation instructions:
1. Disconnect power supply.
2. Open the clamp by pulling the tab upwards.
3. Remove the fan casing from the base.
4. Attach the base to the mounting surface and mark the screw hole.
5. Drill holes; fix the fan base to the mounting surface with screws.
6. Install the body by tightly connecting the clamp
Installation instructions for the speed switch button:
1. Remove the cover with a wide flat screwdriver. To do this, insert a screwdriver into the groove of the plug on the
terminal box casing and knock out the plug with a sharp blow.
2. Install the button in the drilled hole.
3. Connect, according to the diagram using RPI-M(n) 1.5-6.3 connectors (3 pcs., not included). To connect, it is
necessary to bring the wires into flat connectors and clamp them with a crimping tool. You can also connect the
contacts in other safe ways: by twisting, soldering, and welding.
ATTENTION! By installing the speed switch button, the protection level is reduced to Ip42.

Connecting the fan to the mains
The fan has two speeds. Depending on the required fan performance, the phase of the power supply is switched
between the terminals:
For models with flange diameter from 100mm to 315mm
• L1 Low Speed
• L2 High Speed
When setting a high fan speed, depending on the model, it is necessary to connect the fan as follows: L2 (phase of the
supply network), N (neutral of the supply network), protective earth (for models 250, 315).
When setting a low fan speed, it is necessary to switch the phase of the supply network from terminal blocks L2 (phase)
to terminal blocks L1 (phase), connection N (neutral of the supply network), the protective ground remains unchanged
(for models 250, 315).
ATTENTION! In order to avoid damage to the fan, do not simultaneously connect a phase of the supply mains to
terminals L1 and L2.
ATTENTION! All work on installation and connection of fans should be carried out only with the mains voltage
removed.
The fans shall be connected by electricians who have a special permit for the work performed.
Means for disconnecting from the mains supply should be built into the fixed wiring, in accordance with the installation
regulations. The disconnecting device should disconnect all poles. The grounding conductor should not break.
The fan and auxiliary control equipment should be isolated from the power supply during installation and/or
maintenance.
The equipment should be grounded (for 250, 315 models).
Please remove the cover from the terminal box, study the wiring diagram (Fig. 2 or Fig. 3), and make the necessary
connections. Check whether a ground connection exists (for 250, 315 models).
After finishing the connection work and checking the connections to the terminal box, move the cover and make sure it
is fixed.
Installation: The length of the well-established pipeline from the fan should be at least 1000 mm. A shorter pipeline
should be equipped with a rigid lid/grid that complies with EN ISO 13857.
When connecting CECYL fan with IP44, it is required to pass a network cable with a diameter of at least 4 mm through a
cable gland.
The cable gland is designed for sealed input-output of cables from wires in switchboard enclosures.
The compression nut design has special locking notches to prevent self-loosening. A protective diaphragm prevents
dust from entering the enclosure and achieves a degree of protection IP44 and above.

Storage and transportation rules
It is necessary to store the fan only in the manufacturer’s packaging in a ventilated room at a
temperature from +5°C to +40°C and a relative humidity of no more than 70% (at T = 25°C). Shelf life is 2
years from the date of manufacture. Products shall be transported by any type of transport, provided
that consumer or shipping containers are protected from the direct impact of atmospheric precipitation,
from the absence of displacement of transport places during transportation, from the absence of mutual
shocks during transportation and while ensuring the safety of the fans. Transportation shall be carried
out, in accordance with the rules in force for this mode of transport.
Disposal
This appliance is marked, in accordance with European Directive 2012/19/EU on the disposal of
old electrical and electronic equipment (waste electrical and electronic equipment – WEEE). This
Directive defines the EU-wide rules for the collection and disposal of old appliances.
At the end of their service life or failure of the fan or its components, they should be disposed of.
Disposal shall be carried out separately, according to material groups: plastic elements, metal
fasteners.
ATTENTION!
Dismantling and disassembly of the fan should be carried out by qualified specialists with a
complete disconnection from the power supply
Maintenance
• Disconnect the fan from the mains;
