Hygienic Air Handling Unit
Operation & MaintenanceManual
Thank you for choosing
ACS and CLIMACS brandPackage Type Hygienic Air Handling
Units.
In addition to “Air Handling Units Installation, Operation and
Maintenance Manual” supplied with each unit, this manual
contains instructions for the first installation, operation and
maintenance of the software automated system.
All the best...
IMPORTANT
All instructions and information given in the “ Air Handling Units Installation, Operation and Maintenance Manual ” are also valid for this package type hygienic
air handling unit. You can access all our manuals from the products menusin our web site www.acsklima.com
Besides providing heating, ventilation and air conditioning, Package Type Hygienic Air Handling Units are capable of regulating the air pressure of the hygienic area
both positively and negatively. Therefore, air handling units should not be shut down except for the periods of maintenance, cleaning or fault conditions.
Please keep in mind that shut down of the air handling unit may lead to the contamination risk in the hygienic location.
Due to hygienic and package type design of the unit, it should be installed on a level floor with sufficient strength to carry the load of the unit; the installation method
should allow easy cleaning and good drainage of condensed water. The installation location must be free of contamination sources such as chimney, dump, etc.
| Maintenance & Cleaning
MAINTENANCE & CLEANING
The instructions of the manufacturer should be followed prior
the operation for the first time (or after annual maintenance).
After that, below points should be checked:
For annual maintenance, shut down the air handling unit and turn off all motor switches, turn off the power.
Make sure that the all compartments are cleaned and no foreign object or material is left in the unit. Please check no duct isolation residues, tapes, nuts, hand tools are left behind.
Please check all the handles on doors and access panels.
If the unit is installed outside make sure that it is placed under an overhead shelter and check the joints of gaskets.
Duct connectionsand dampers
Cooling unitsand refrigerant check
Drainageand siphon check
Fan and motorconnections
Connections for allelectrical parts
and sensors
Door locksand hinges
Air tightness and pollutioncheck of filters
Water and refrigerantleakage control in heating,
cooling and DX exchangers.
In addition to check of connections;all notifications shown on the control panel must be carefully inspected and intervened.
| Air Filters & Panel Filters
The air delivered by the air handling units are cleaned by the filters
as the air passes through.
Failing to check the filters as instructed, may cause health risks
and faults in the unit; it also may cause to increased energy
consumption.
AIR FILTERS
Weekly checking and cleaning of the filters is necessary following the commissioning
of the unit. A drop in the pressure level is an indication of the filter pollution. The time
that a filter takes to get polluted depends on the operation duration of the unit as well
as the ambient weather condition and pollution where the unit is located, eg., city
and industrial regions. An optionally available automation system can be used to
detect and notify the pollution level of the filters.
If the unit is actively operated, change the front filters at least once per three to six
months depending on the pollution level of the ambient environment. Please take
care to insert the new filter correctly and check also the gaskets on filter skids; if worn
out change the gaskets and finally using clamping lever fix the filters in position to
provide air tightness.
PANEL FILTERS (FRONT FILTER)
Panel filters can be cleanedby one of the following methods:
Shaking and vacuum cleaning,
Compressed air,
Washing with warm water(not pressurized)
| 2nd & 3rd Stage Filters
2nd and 3rd STAGE FILTERS
Check if there is any pressure drop and inspect the condition of the gaskets on the
skids. The most significant indication of a filter pollution is the pressure drop.
Max Pressure Difference = 1.6 x Initial Pressure Difference + 40 Pa
When the max pressure drop is reached remove and renew the filter. Make sure that
the filter frame firmly sits on the outer cassette and check that the contact between
doors and filters is good.
Correct positioning and good sealing affect the filter performance.
"Please contact to ACS engineers to get
information on special filters "
BAG, MPACK AND HEPA type filters cannot be cleaned and reused. These should be changed
upon completion of life cycle
Ensuring the filter sealing

Note: ACS package type hygienic air handling units are supplied with automation system by which you can easily monitor the filters on touch sensitive panel screen.
| Air Dampers
AIR DAMPERS
Check that the rotation of the flaps is not obstructed.
Do not touch the body or flexible connections.
Remove the accumulated dust by compressed air.
If you observe any problem in opening or closing of the flapscall an authorized service.
STEAM TYPE HUMIDIFIERS
At the beginning of each season, clean the strainer in the steam feed of control valve.
Annually check the control valve, condensed water discharge system and dispersion pipe.
Humidifier boiler and electrodes should be checked at least once per year. If the water used in the system is not distilled water then the frequency of checks should be increased depending on the chemical composition of the water used.
Following the periodic checks of humidifier section the operation of the humidifier can be checked from the air handling compartments after humidifier. Looking towards air flow direction a steam increase should be observed.
Silencers chambers should be inspected carefully. If there the surfaces of the silencer chambers are damaged, the glass wool inside may be caught by the air flow and carried away towards the filters. This may damage the filters and pollute the ambient air.
(ACS, wraps the glass wool by a special fabric in order to minimize the risk.)
IMPORTANT
| Heaters, Coolers & Heat Recovery Exchangers
HEATERS, COOLERS AND HEAT RECOVERYEXCHANGERS
Cleaning of air inlet side should be checked at least once per year. Surrounding weather and environmental conditions may require more frequent checks. Remove the parts and clean them applying pressurized water in the opposite direction of air flow.
If the pollution is severe please check the condition of the filters.
Discharge the water inside the exchangers
Dismantle the exchanger and piping connections
Remove the side panel
Dismount the nuts fixing the exchanger
Remove the exchanger
Please follow below steps if water heat exchangers will be removed for cleaning and
maintenance:
Clean the surface and the fins of the exchanger
Charge the exchanger with water
Locate the leakage
Discharge the water
Using oxy-acetylene welding repair the small cracks or holes located on copper pipes
It may not be possible to repair the exchanger if the reason of leakage is cracks caused by
freezing, or if the leakage is between the fins.
Charge the exchanger with pressurized water to check welding.
Please follow below steps to locate leakage in water heat exchangers:
" Prevent freezing of water inside heat exchangers "
LOCATING LEAKAGE IN DX (REFRIGERANT CHARGED) HEAT EXCHANGERS:
After shutting down the unit and switching off the power, clean the surface of the exchanger by compressed air or water.
Straighten the bent fins by using a fin comb.
If ice is observed during operation let the ice melt down naturally and inform the technical service
If you think that there is a refrigerant leakage in the system please inform the technical service
If the water inside the pipes of exchanger freezes, this will severely damage the pipes. For this reason, if there is a risk of freezing the antifreeze should be added to circulating water. If you are planning to take the exchanger out of operation for a short period, at least, make sure the water inside the exchanger is partially circulated.
| Heaters, Coolers & Heat Recovery Exchangers
Some condensed water might be observed
in the return compartments of heat
exchangers that serve for cooling or heat
recovery. Please check the condensing water
drainage
Please clean by using either compressed air or water in the opposite direction to air flow.
You can also use a very soft brush.
Straighten the bent fins by using a special fin comb.
Air Flow Direction
| Fans
FANS
Make sure that the impeller is fixed on the motor shaft tightly.
Check if fan and motor rotate freely.
Make sure that there is no foreign object at the inlet of the fan.
Check the rotation direction of the fan. To do that, momentarily switch on and off the power then observe the rotation direction of fan.
Check that the motor shaft and fan inlet flange are aligned.
Check the motor and its connections.
Check that flexible connections are secured tightly and not damaged; duct connections are designed according to the recommendations of the manufacturer with acceptable engineering applications.
Check the setting of the motor protection switch is correct.
Switch on the power and let the fan to reach to its full speed.
Do not forget to observe below points!

z
Excessive vibration
Proper lubrication Motor current and voltage values
Strange noise Axial alignment of motorand fan flange
| Fans
If any problem is observed shut down the unit immediately.
Switch off the power.
Secure the fan to prevent unintended rotation of the impeller.
Inspect the source of the problem carefully and rectify it if necessary.
The operation of the fan should be observed periodically for the first 8 hours of the operation.
Pay attention to excessive vibration or noise during this observation.
Check that the input current of motor and temperatures of the bearings are within the limits specified by the manufacturer.
Finally, switch off the fan to do below checks:
x y
z
Axial alignment of motorand fan flange
Bearing temperature Fan and motorfixing bolts
Fan speed should not be changed without consulting the firm. If a higher speed of
rotation is required the power rating of motor should be checked for required capacity.
The load on the bearings and fan must be recalculated by the manufacturer. Vibration
absorbing isolators should be checked once per year for damage
Annually check the balance of the fan. Clean dust on the suction funnel and rotor.
Accumulation of dirt on the rotor may impair the balance. If pollution is severe check the
filters and upgrade the filters if necessary. If the fan is equipped with a suction damper,
every three months check the suction damper for proper operation. To do that, switch
off the fan first then operate the suction damper and observe the operation of
servomotor, connections and flaps.
| Fans
MAINTENANCE PROGRAM
A protective maintenance program is an important part of an active safety program.
Maintenance works should be carried out by trained and experienced personnel.
Do not attempt to conduct any maintenance unless the power is switched off and
the fan is secured.
Package type hygienic air handling units are the kind of devices that directly relate
to human health. Therefore, except for routine cleaning and maintenance, the
works requiring a special attention must be performed only by the trained
personnel. Maintenance period varies depending on the operation conditions.
