HEYLO FD 4000 Axial Ventilator

General aspects

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.

Introduction This chapter contains general information on the unit and manual.
Target group This manual is intended for technicians who install the unit, carry out maintenance work and replace faulty parts.
Copyright The duplication of this manual in whole or in part shall be permitted only upon written approval of HEYLO GmbH.
Reservation HEYLO GmbH reserves the right to carry out modifications and improvements on the product and in the manual at any time without previous announcement.
Disposal The unit has been designed for many years of operation. If it has to be disposed of, the competent legal regulations have to be observed in an environmentally-gentle manner.

DANGER OF ELECTRIC SHOCK WARNING! The unit has to be earthed.

Use indoors only.
Protect against spray water.
If the motor or the winding has got wet, they have to be dried completely prior to use.
Cleaning can be carried out by compressed air, a vacuum cleaner, or by wiping with a moist cloth. Never use a hose or high-pressure cleaner.
Plug the power plug only into a socket secured by a ground fault circuit interrupter.
Never interrupt the grounding.

FIRE HAZARD

Keep the air inlet and the protective grille free from choking and dirt. A reduced air current may lead to the motor overheating. Do not use in the vicinity of curtains or other things that may clog the air inlet opening.
Do not use in the vicinity of open fire and heat sources.
Do not use or store in areas where combustible vapors of petrol, solvent, or diluting agents are present.

Safety guidelines

WARNING! Prior to opening the housing for cleaning and maintenance purposes always remove the mains plug.

Always set up the unit on a solid and plane surface.
Switch off the device and remove the plug prior to lifting or moving the unit. The strong air current makes the control of the unit difficult.
Check the power cable prior to use. Do not use the unit with a damaged cable. Replace the cable by a cable of the same type with the corresponding current strength. Protect the cable against damage by switching the unit off first of all and then pulling the power cable. Never pull the cable, but get hold of and pull the plug.
The unit has been designed for operation at 230 V / 50 Hz. Check whether the socket is earthed.
Handle the unit with care. Do not drop, throw or place on an unstable surface, from where the unit may drop. Rough handling may damage the unit and may lead to dangerous situations or may void the guarantee.
Keep away from children. Make sure that the unit is not accessible to children when operated unattended.

Use

Ventilator FD 4000 is the ideal working instrument for industry, modern craftsmen, and service providers – for ventilation of workplaces, drying of rooms, and wall surfaces after damage. FD 4000 is set up quickly. On account of the various setup positions, the ventilator can be used very flexibly. On account of the high protection class, the FD 4000 is especially suitable for rough use on building sites.

Setting up the unit

Ensure a secure location for setting up the ventilator. The unit must not be operated in puddles or in the area of splashing water. Check to see that no foreign matter is captured by intake air and gets into the fan wheel.
Selecting a working position
THE FD 4000 is constructed so that it can work in several positions. Every position uses a different angle in order to immediately direct the airflow to where it is required for effective drying. The arrow at the side of the unit shows the direction of airflow. Vertical – Place the FD 4000 on the feet (put handle sideways) which are a long way from each other in order to let the ventilation airflow in parallel through the room.

Front side down – Place the FD 4000 on all four feet, with the grid facing downward on the switch side. In this position, the air is directed downward to the floor for targeted drying.
Tilted back – Place the FD 4000 on the narrow feet (handle up). Tip the FD 4000 back until the unit sits at an angle on the bottom feet. In this position, the air is directed upward for drying parts that are located higher.
Stacked operation – Place one FD 4000 on a solid, even surface onto the feet which are a long way from each other (handle sideways). Put a second FD 4000 onto it so that its rubber feet sit in the dents on the lower unit. When stacking units on each other, exercise caution in order to avoid injuries due to units falling down.
Tilted forward – Place the FD 4000 onto the narrow feet (handle up). Tip the FD 4000 forward until the unit sits at an angle on the bottom feet. In this position, air flows in parallel to the bottom of the unit.
Front side up – Place the FD 4000 on all four feet, with the grid facing upward on the switch side. In this position, the air is immediately directed upward in order to dry the ceiling, for example.
Stack for storage – FD 4000 ventilators mesh together so that it is easy to store and transport them. Set up the units, with the grids facing each other. Turn the units a bit until the feet are not in line anymore.

Cooling and ventilating

Overheated rooms can be cooled using the high-volume airflow of a blower. Put the device on the floor or another even surface and allow air from cooler areas or from outside to flow in. The feed temperature of the air must not exceed 60 deg. C!

Operation

Set up the unit with the direction of the fan towards the requested operating position. The direction of the air stream is indicated by the direction arrow on the side of the unit (1).
Push the plug into an earthed 3-pole 230 V shockproof socket.
Before switching the unit on, note the meter reading of the energy meter (2). After completion of the work, the meter reading can be passed on to insurance, for example.
Set switch (3) to “Off” on any fan speed. When set to “MAX”, the ventilator runs with the highest air flow rate.
Prior to leaving the device, check for perfect operation. Never move the FD 4000 when switched on.

Notes on MID counter:
The unit is fitted with a MID counter. This energy meter is in conformity with the German Weights and Measures Act and is considered calibrated for up to eight years after manufacture (the manufacturing date is rendered on the counter). Thus, according to the German Office of Weights and Measures, the counter is suitable and approved for the determination of energy consumption.

Transport
During transport in a vehicle, the FD 4000 has to be secured by safety straps in order to prevent that it slips and is damaged or passengers are injured.
NOTE!
Safely load to prevent that impact of the motor, fan blades, or parts in the inside are damaged.

Maintenance/repair

CAUTION: Always switch off the fan and remove the mains plug before maintenance and repair. The fan wheel may continue turning when the housing is opened, and the unit is switched on.
Before every use
Check power cable: Check the power cable for cuts, abrasions and damage. Do not use the unit when the cable has been damaged.
Weekly maintenance
Clean the protective grille: Check the fan propeller wings for dirt, dust and deposits. Deposits of fluff and dust reduces the air flow and may lead to overheating of the motor which constitutes a fire hazard. Use a moist cloth to clean the fan propeller wings or use compressed air. Remove all collected fluff and other materials from the protective grille. Use a vacuum cleaner or a moist cloth to remove fluff and dust from the motor and the cover of the protective grille. WARNING! Make sure that no water penetrates the motor.
External inspection: Check external parts, and make sure that they are attached correctly. Check the unit for abnormal noises. Repair or replace parts as required.
Housing cleaning: Use a moist cloth to clean the housing. The original shine of the unit can be restored using HEYLO POWER CLEAN plastic cleaner (Art. No 1800104).
When working in atmospheres with mold contamination, the disinfectant CITRIX can be used. Article No. 1800204 is can be ordered in 5-litre container + spray bottle, article No. 1800301.
Monthly maintenance
Check the electric system: Check the power cable for damage at regular intervals. Regularly remove the fan, and check the cable work for worn cables, loose attachments and discoloration. Replace or repair damaged cables, if and when required. WARNING! Damaged cables may cause electric shocks or fire.
Ball bearings of the motor: The ball bearings of HEYLO ventilators have a lifetime of lubrication. For this reason, do not lubricate.
