Use of the unit 20
Air handling units are supplied with locked access doors as an option so unauthorized persons are not permitted to enter the sections which represent a danger the most important potential dangers for life and health are described below the units are manufactured in conformity with machinery normative 98 37 ec if the user thinks to take further measures to restrict every possible remaining danger he will be able to recognize them by the general description below 21
Also lockout switches and suitable warnings should be used maintenance personnel should engage the lockout switch before starting any maintenance and repairs do not forget to protect against unlock by anybody else 21
Centrifugal fans in air handling units are located inside a casing so accessibility to the fan is occasional or infrequent for this reason protective devices are offered as optional accessories only at specific user s request however as in case with other machinery involving moving parts common sense and caution will preserve personnel safety 21
Drive guards safety guards should be used when drive systems are accessible by the personnel limit switch cuts off the power supply of the fan motor when door opens as the fan keeps on rotating do 21
Fan inlet and outlet guards centrifugal fans in air handling units are usually connected directly to ductwork 21
In addition to follow the manufacturer s installation instructions care must be taken to ensure compliance with federal state and local rules regulations and standards 21
Not attempt to enter the unit within minimum 2minutes after opening the door 21
Prevent of common dangers and risks 21
Recommended safety practices 21
The available optional guarding devices are 21
This publication explains the proper use and installation of centrifugal fans in order to warn operating and maintenance personnel of the commonly recognized dangers associated with this equipment 21
Which will prevent the contact with the internal moving parts in case there is an exposed inlet or outlet which could represent a danger suitable guards can be installed 21

After two week operation 24
Maintenance 24
After inspection and replacements if necessary proceed in accordance with operation instructions before running the unit again 25

Following must also be noted about maintenance works 25
For detailed information about lubrication of bearings belt tension and alignment controls changing of pulleys see related sections in this manual 25
Coil sections 26
Filter sections 26
After opening the service door the filters can be taken out by pulling aside 27
Humidifier sections 27
Humidifier should be cleaned regularly the period changes according to the operating conditions air specifications and water quality during periodic maintenance of humidifier checks mentioned in its own manual should be performed 27
Prevent of common dangers and risks 27
Sound attenuators 27
Sound attenuators can be taken out from the service door by unscrewing the components from the top and bottom panels attenuators can be cleaned by vacuumed or compressed air 27
Synthetic bag filter can be cleaned by vacuumed or compressed air besides can be washed with the sensitive detergent and warm water 27
Belt tension and alignment control 28
Change of pulleys 28
Bearing inner diameter mm 29
Bearings have to be controlled and cleaned regularly have to be lubricated adequately to prevent direct metallic contact between rolling elements to prevent wear and to project bearing surfaces against corrosion 29
D bearing inner diameter mm 29
Excess grease will cause the operating temperature to rise rapidly particularly when running at high speeds therefore only the bearing should be completely filled whilst the free space in the housing should be partly filled between 30 and 50 where bearings are to operate at very low speeds and must be well protected against corrosion it is advisable to completely fill the housing 29
Fan speed 29
If the fan works in particular conditions relubrication intervals have to be corrected concerning the temperature and surrounding factors according to the following formula 29
Ks surrounding correction factor 29
Kt temperature correction factor 29
Lubrication of bearings 29
N fan speed rpm 29
Relubrication interval depends on the fan speed and bearing internal diameter and is calculated by the following formula 29
T 10 x 14x106 n x d 4 x d 29
T relubrication interval h 29
Tc corrected relubrication interval 29
Tc t x kt x ks 29
Temperature correction factor kt takes into account the reduction of relubrication interval when bearing temperature raised over 70 º c 29
The fans with higher shaft power are equipped with bearings with cast iron support the lubricant filled in a bearing gradually loses its lubricating properties during operation therefore it is necessary for grease to be replenished or renewed from time to time the grease used is always lithium soap type suitable for all temperatures within the operating range 29
The fans with low shaft power are equipped with bearings in a rubber housing which absorbs a part of vibration when you change the bearing it is very important to change the rubber housing too these bearings don t need to be lubricated 29
