Safety guidelines

CAUTION:
Read carefully before starting up ! Please observe the notes in the operating instructions carefully. In case of non-observation, the warranty claims will become void. The manufacturer shall not be liable for any damage and/or consequential damage resulting.

Prior to the first initial operation: Do NOT put the air mover into operation, if you discover transport damage on the turbine blade, cover or housing.Keep away from children: Do not allow children to play with or in the vicinity of the unit Electric connection: HEYLO PowerVent 4200 EX has been designed for operation at 115 / 230 V and 50 / 60 Hz. In explosive atmospheres, the device may be operated only with attached special plug. In normal environments, an adapter (art. No. 1450209) can be used. The sockets used have to be earthed ! Prior to connection to the mains, please always make sure that the switch has been set to OFF. Protect the power cable against damage: Never use the unit with damaged power cable. If the power cable has been damaged, it has to be replaced by a cable of the same type and dimension. Extension cable: Use approved extension cables only ! Using cables of wrong size may lead to fires or electric shock and damages to the unit. Handle with care: Do not drop or throw the unit as this may cause damage to the unit or wiring. Operate on solid surface: Start the air mover only if it is in a stable and upright position. If the unit is in an uneven position and runs at full speed, it should not shift. When the unit moves, check the rubber feet for damage and replace them, if and when necessary. Secure during transport: When transporting devices in vehicles, secure against slipping.

During operation :
Keep dry: The unit must not be operated in puddles or in standing water. Do not store or operate outdoors. If the electric wires or parts of the unit get wet, the unit has to be thoroughly dried before re-using. Safety: During the operation of the ventilator, eye and ear protectors have to be worn. Keep your fingers and hands away from the paddle wheel. Never move the air mover whilst running Keep the air openings free: Do not cover or block the air inlets and outlets. Do not use any speed controller: In order to reduce the risk of fire or electric shock, turbo dryers should not be used with electronic speed controllers. Repair of the device:Stop the device immediately if you hear loud mechanical vibration noises or vibrations. Please have the repairing work carried out by service partners of HEYLO Company only.

Possible application
In potentially explosive environments, transport ventilator PowerVent 4200 EX is the right choice. It draws off dangerous gases safely and quickly. The housing made of a robust ABS carbon plastic passes voltage into the floor and thus prevents static charges and for this reason dangerous sparking. The housing and motor sealing is in keeping with the high protection class IP65 and offers effective protection against dust and water.

Operation
Before starting up the ventilator, set the unit to the correct voltage. (230 V is preset)Before starting up the ventilator, set the unit to the correct voltage. (230 V is preset) Connect the unit to an earthed socket and set to switch A to ON. Check correct operation before leaving the unit unattended. Do not move or carry the air mover during operation. Observe the direction of air. It is marked by an arrow B on the housing.

Setting – voltage range
If the unit is connected to a 115V network, the voltage selector switch has to be set to the corresponding voltage. For this purpose use a slot screwdriver to undo the safety screw C, and then set the switch to the requested voltage range:

Special features in explosion-proof areas:

•  Installation conditions and different hazardous areas have to be observed.
•  Connect device to explosion-proof power socket only.
•  Only use antistatic air hoses and ground them, when required.

Accessories

Please use suitable accessories only !For use in non-explosive areas you can use the following accessories:

1. Zones – Explosion groups – Temperature classes
2.  Explosion protection | Classification
3. The division into temperature classes

Zones – Explosion groups – Temperature classes

Introduction
Explosive areas are divided into zones; the apparatuses into device groups and device categories. Given a certified unit, the marking on the type plate reveals, for which zone the explosion-proof apparatus may be used.

Division into device groups
The device groups are divided up into group I and II, whereby group I deals with underground mining, and group II covers gas and dust explosion protection in all other applications.

Division into zones
Explosive areas are divided up into six zones whereby the division depends on the probability of how frequently and for how long it has to be calculated that a hazardous explosive atmosphere occurs. A differentiation is made between combustible gases, mists, steams and combustible dusts. For gases, mists, vapours zones 0, 1 and 2 apply whereby the demands on the apparatuses used there increase from zone 2 to 0. Apparatuses for zone 0 have to be built in such a way that “a sufficient explosion protection is ensured even when an ignition protection type fails or when two failures occur”. For example, a potential-free sensor passively installed in zone 0, which is operated in an intrinsically safe current circuit (II2(1)G [EEx ia] IIC), has an additional own approval. For dusts zones 20, 21 and 22 apply whereby the demands on the apparatuses used there increase from zone 22 to 20. Equipment for zone 20 and 21 have to be approved especially for this use. PV4200 EX is not suitable for explosive dusts.

Explosion protection | Classification

Explosion groups, temperature classes

If the device group and the device category is used to determine, in which zone an apparatus may be used, the explosion group and the temperature class determine, for which media the apparatus may be used within the zones. In turn, the type of ignition does not present a quality characteristic but is a constructive solution chosen for the apparatus to realise explosion protection.

Division into explosion groups

Depending on the type of ignition protection the explosion-proof apparatuses for gas, fogs and vapours are divided up into three explosion groups (IIA-IIB- IIC). The explosion group is a measures for the flammability of gases (explosive atmosphere). The demands on the apparatus increase from II A to II C.

Division into temperature classes
In case of explosion-proof apparatuses which are installed within the ex area, a division into six temperature classes (T1 to T6) is made. As is wrongly assumed frequently, the temperature class is not the application temperature of the apparatus, but the maximum permissible surface temperature of the apparatus, which relative to an ambient temperature of +40 deg. C must not be exceeded at any part of the surface and at no point in time. The maximum surface temperature must definitely be lower than the ignition temperature of the surrounding medium. The demands on the apparatus increase from T1 to T6.

Maintenance / repair

CAUTION!
Remove the mains plug before maintenance and repair. Inspection of the electric system: Check the power cord for damage in regular intervals. Remove the housing in regular intervals (at least once a year) and check the internal wiring for bare wires, loose fasteners and discolouration. If and when necessary remove and repair the damaged cable. Do not take the air mover apart for maintenance purposes. The air mover is maintenance-free. Replace the special screws and washers as well as parts of the air mover by original HEYLO spares parts exclusively. Clean air inlet: Clean the air mover regularly in order to remove any collected dust and dirt. Lint or other dirt which has collected at the air let has to be removed. Use vacuum or pressurised air to remove lint and dust from the impeller, motor and side covers. Clean housing: Clean the housing with a mild detergent and water. Use vinyl cleaner or polish to restore the original glossiness. Do not use any solvents (such as MEK, acetone), which contain chlorinated hydrocarbons. Checking the outer side: Check the external components and make sure that have been installed correctly. Listen for unusual noises. Check the rubber feet on the frame for wear and damage. Motor and wiring must remain dry: In order to not damage the electric components, the turbo dryer must not be cleaned by a water hose or pressurised water. If electrical components get wet nonetheless, they have to be dried immediately.
