How EcoloAir system operates
The MC8 controller is used to read the analog signals from pressure transducers and to control speed of exhaust fan motor in order to maintain the constant airflow. It also drives the operation of ecolo compressor according to preset duty cycle or continuous run.
A small 7‘‘ touch screen is used to monitor the whole system. Screen will provide:
• Information on filters condition (remaining life of the filter (%)
• VFD actual speed (%)
• Features to operate ecolo compressor and to change the time settings on it
• Displays all alarms of the system
• HMI also provides calibration features for startup purpose
How to move around the screens in HMI
There are total of 6 screens used for this application. They are shown below in consecutive order.
EcoloAir Operation, Maintenance & Service Manual
7
Moving between screens function is available through the labeled screen buttons at the top of each screen. Press the ‘‘Fast Select’’ button at the lower left corner of the screen to display a pop up menu of screen options. Press the ‘‘Fast Select’’ button again to remove the pop up menu.
The operator can go directly to the alarms screen in order to verify what alarm has occurred.
Touch screen operation
The size of the touch screen by default is 7‘‘.
Screens explanation:
1. Main screen - Filter screen
The screen displays the value of the VFD speed of the exhaust fan, particular filters life remaining
(status) and alarms warning symbol. An off/on button to start/stop the operation of the system is also displayed.
EcoloAir Operation, Maintenance & Service Manual
8
The first bar graph relates to the VFD speed.
The second bar graph relates to the DP (static pressure in inches of water column) for the pre filter.
The third bar graph relates to the DP for the medium filter.
The fourth bar graph corresponds to the DP for the absolute filter.
(The filter bar graph display shows percentage of life remaining in each filter. See the
Start Up Operating Instructions section for the specific static pressure range for each filter.)
Regular operation – Screen shows the current value of VFD speed.
All filters are at 100 % life remaining when new filters are installed, filters are all 100% clean, VFD calibrated speed at certain percentage % (this relates to certain static pressure [“ WC] at main DP) when filters are clean and last there are no alarms in the system.
2. Ecolo screen --- ecolo odor control screen
Ecolo odor control unit operation is enabled through the ecolo screen.
The three position selector switch (Off/ Cycle & Continuous) enables the operation of the compressor.
Off - unit is not operational.
Cycle - unit runs in cycles (on and off).
Continuous - unit runs on all the time, until other command selected.
Numeric display ‘‘Ecolo ON time’’ sets the time in seconds for unit to be on.
Numeric display ‘‘Ecolo OFF time’’ sets the time in seconds for unit to be off.
Once these times are set, if selector switch is in cycle mode, unit will run for a preset time, when this time has been elapsed, the operation of the compressor automatically stops and it will be off for the preset time set in off mode. The status changes again to ‘‘on’’ state and goes in cycles as previously described.

3. Calibration screen - Calibrate screen
How to calibrate the system during start up by using HMI
First appearance is the ‘‘filters’’ screen ---appears first when the system is off.
By pressing the off/on button, screen displays ‘‘ON’’, the fan starts and goes to the speed which will maintain a default value --- a manual set point of the main
DP of 0.5‘‘ (variable) set by program.
For start up purposes and setting up the system, a service technician will need to go to the screen called ‘‘calibrate’’. Calibration requires Security Level 1 access.
Calibration steps:
1. Press the ’’Initiate calibration’’ button. This initiates the calibration process. ’’CALIB OFF’’ changes its state to ‘‘CALIB ON’’.
2. The fan will go to 70% speed and HMI displays that calibration is active (calibration display
‘‘OFF’’ goes to ‘‘ON’’ state).
3. Measure the differential static pressure on the TAB port or velocity on the hood filters for old style hoods. If airflow is Ok, then press ‘‘STORE’’ button. Make sure you see the new calibrated value ‘‘Store fan speed %‘‘ and then press once ‘‘CALIB ON’’. This will finish calibration process.
4. In case of an unsatisfactory measurement:
5. Press jog buttons ‘‘INC’’ and ‘‘DEC’’, the speed of the fan will be increased or decreased to allow for airflow changes. You can monitor the speed in the Fan speed % block.
6. Measure the hood differential static pressure again.
7. Repeat using ‘‘DEC’’ or ‘‘INC’’ until design airflow is reached.
EcoloAir Operation, Maintenance & Service Manual
10
8. When design airflow is reached, press the ‘‘STORE‘‘ button. This will store the calibrated values for main pressure transducer, pre filter, medium filter and absolute filter transducers. It will also store the calibrated VFD speed (‘‘Store fan speed’’). The HMI displays that calibration is off and the last step is to undo the ‘‘initiate calibration’’ button again --- confirmation that calibration has been done.
From this moment on the system will automatically follow the calibrated values in order to maintain the constant airflow and it will start monitoring the status of the filters (filter remaining life).
4. Alarm screen
Alarms screen appearance:
Possible alarms
Alarms which can appear on the ‘‘alarms’’ screen are:
1. Pre-filter clogged
2. Pre-filter missing
3. Medium filter clogged
4. Medium filter missing
5. Absolute filter clogged
6. Absolute filter missing
7. Fire
8. Change filters (if VFD speed is @100 % for more than 10 min!)
9. Low ecolo level (low level of ecolo solution in the tank)
10. Fan failed!

To replace filters, proceed as follows:
1. Shut off fan.
2. Loosen the access door latches and open door.
3. Check how filters are set in place to prevent air by-pass.
4. Remove filter clamp on absolute filters with hook handle provided in unit, located on inside of access door.
5. Remove all filters by sliding out the filter along bottom of filter track.
6. Slide the new filters along the bottom filter track and seat properly along filter by-pass gasket.
Replace all filters in this manner. Ensure all filters are seated properly and replace filter clamp to lock Absolute filters in place.
7. Check that pressure transducer air tube connection have not been disturbed by removing pressure tube chase.
8. Close access door and lock all latches.
9. To start fan, turn on disconnect switch at fan.
10. If the fan stops, remove the filter access door and check if all filters have been replaced and are seated properly.
11. Should fan continue to shut off, check all pressure transducer settings.
FILTER REMOVAL TEST
To perform Filter Removal Test, proceed as follows:
1. Ensure all filters are in place and properly seated.
2. Remove one absolute filter.
3. Start fan. Alarm should sound and fan should shut down within one minute.
4. Replace High Efficiency filter.
5. Restart Fan.
NOTE: A FACTORY INSTALLED FIRESTAT SET AT 350˚F (177˚C) IS LOCATED AT THE ENTRANCE
TO THE EXHAUST FAN. IT WILL SHUT OFF THE EXHAUST AND SUPPLY FANS IF THE SET
TEMPERATURE IS REACHED.
FIRE DAMPER
The Fire Damper is located at the discharge set of the EcoloAir Filter Module. All Fire Dampers are supplied with fusible links set to close at 286˚F (138˚C) or 165˚F U.S. Only. Should the fusible link melt and blades shut down by gravity, linkage replacement is necessary as follows:
1. Loosen the access door latches.

FAN WHEEL REPLACEMENT
It is unlikely the fan wheel will require replacement. However, if the wheel requires balancing, it can normally be done in the field by a certified fan technician. Should the fan wheel require replacement, the work should only be performed by a Halton certified fan technician.
BEARING REPLACEMENT
1. Remove belts and the fan sheave. To remove fan sheave, remove the cap bolts and screw
them into the threaded holes in the bushing. Snug up all bolts then continue to tighten each
cap bolt in half turn increments until the sheave comes loose from the bushing. The bushing
and sheave should now slide off the fan shaft.
2. Loosen the set screws on the locking collars of bearing.
3. Remove the fan wheel and fan shaft by sliding the fan shaft out through the bearing collars.
Polishing the fan shaft with emery cloth and some light lubrication on the fan shaft will
make removal much easier.
4. Remove bolts, fastening the bearing to the top and bottom bearing base plates.
5. Re-install equipment in reverse order of removal. Care should be taken to properly tighten
the set screws in the bearing locking collar’ see chart for recommended tightening torque
of set screws.
6. When replacing the fan sheaves, slide sheave and bushing onto the fan shaft and insert the
cap bolts into the non-threaded holes of the bushing and screw into threaded holes in
sheave. Tighten each cap bolt a half turn in rotation until tight.
7. Ensure proper belt tension and sheave alignment. The use of straight edge is recommended
to ensure proper alignment and maximum efficiency.

SHEAVE ALIGNMENT
Align the drive by the four-point method with a piece of string or a straight edge. The two sheaves will be aligned when two points (near and far) on the face of each of the sheaves touch the straight edge of the string when the string is a straight line. Refer to the figure below for correct alignment.
Fan Sheaves Misaligned
Fan Sheaves Aligned
EcoloAir Operation, Maintenance & Service Manual
18
BELT ADJUSTMENT
Measure the belt span, (see image). Using a spring scale, apply a perpendicular force to any one of the belts at the mid point of the span. Measure the force required to deflect any one of the belts 1/64” (.40mm) for every inch (25mm) of span length. For example, the deflection for a 32” (813mm) span would be 1/64”
(.40mm) multiplied by 32, or 1/2” (13mm). The force required to deflect the belt is listed in the table below.
Initially, tighten the belts to the values listed in column
“Run-In Time”. There will normally be a drop in tension during the first 24 to 49 hours of operation. During this
“run in” period, the belts seat themselves in the sheave grooves and the initial stretch is removed. After a day or two, the drive should be stopped and another check made for the correct amount of tension. The tension should now compare with the values in column “Normal
Time”. If the force is below the level in column “Normal
Time”. The belts are too loose. If the force is greater than the high level, the belts are too tight. Readjust so that the deflection force is between the high and low value in column “Normal Time”.

START UP OPERATING INSTRUCTIONS
IMPORTANT: Initial system start-up and certification by factory authorized personnel only.
Operating system prior to certification will void warranty.
• Turn on main disconnect switch at EcoloAir fan.
• The EcoloAir filter unit is designed to operate with the following pressure drops across each filter
stage.
1) Pre Filter
2) Medium Efficiency Filter .4” to 1.25”
3) High Efficiency Filter
.2” to .75”
.75” to 2.0”
When the pressure drop for each filter bank exceeds the upper limits, an audible/visual alarm will
sound and activate a pilot light.
The alarm is a warning only, and does not shut the system down. The alarm can be silenced by
pushing the alarm reset button in the centre of the Ecology panel.
The firestat is also capable of triggering an alarm on the control panel. Upon the firestat detecting 350°F, it will shut the exhaust fan off and display a FIRE alarm. Once the firestat sees the temperature drop down below 320°F it will clear the alarm on the panel and restore operation of the exhaust fan.
• There are two other alarm conditions:
1) “A filter not in place” sensing system. 2) A fire state to sense excessive temperatures in the
duct. Should either alarm be triggered, the audible/visual alarm will sound, an indicator light
labeled “filters overall” will be illuminated, and the system will shut down. After the cause
of the alarm has been corrected, the system can be restarted by pushing the reset button
and also turning the main disconnect switch to the “OFF” position. then back to the “ON”
position.
MAINTENANCE INSTRUCTIONS
NOTE: Heavy hamburger type operations require extra maintenance and frequent filter changes. We
recommend a maintenance contract be set up for this type of operation.
MONTHLY:
• Check condition of air filters. Replace if necessary.
• Check odor control liquid level. Replace if necessary.
• Check odor nozzle condition (check for debris)
QUARTERLY: (to be performed by a qualified service agent).
• Check belt tension at exhaust fan. Tighten as required.
• Check belt alignment.
• Lubricate motor bearings.
• Lubricate fan bearings.
• Check contacts on motor starter in control panel.
• Check amperage draw of fan motor.
• Check to see if the overall filter warning system operates correctly. This can be done by removing
the high efficiency filters and starting the system.
• Check fusible link on the fire dampers (filter section)
When replacing belts when multiple belts are used, they MUST ALL BE REPLACED, as they are a matched set.

ROUTINE MAINTENANCE
1. A preventive maintenance program is an important aspect of an effective safety program.
Consult the manufacturing or other qualified service agents with question concerning changes observed during periodic inspections and routine maintenance.
2. The fan manufacturer’s operating and maintenance recommendations, as well as the components manufacturer’s instructions (such as motor, bearing, drives, etc.) should be strictly followed.
3. Maintenance should always be performed by experienced and trained personnel who are aware of the hazards associated with rotating equipment. Do not attempt any maintenance on a fan unless the fan power supply has been locked out and tagged out and the impeller has been secured.
4. When performing maintenance functions which include disassembly of the fan, careful consideration should be given to the size, weight center of gravity, and lifting means of the fan components. It should also be noted that the outboard bearing on some fans such as arrangements 1,8,9 and 10 is often cap-loaded. Removal of the securing means may result in a sudden change in impeller position.
5. Historical data is often the best indicator for determining the operational condition of the fan. Maintenance logs which include lubrication, vibration levels, temperature levels, power requirements, inspection, and other pertinent records should be maintained and consulted as necessary when assessing the condition of the fan.
6. Under normal circumstances, handling clean air, the system should require cleaning only once a year. However, the fan and system should be checked at regular intervals to detect any unusual accumulation.
7. The fan impeller should be specially checked for build-up of material or dirt which may cause an imbalance with resulting undue wear on bearings and belt drives. A regular maintenance program should be established as needed to prevent material build-up.
8. Periodic inspection of the rotating assembly should be made to detect any indication of weakening of the rotor because of corrosion, erosion, or metal fatigue. Where signs of deterioration are found, lock out and tag out the impeller until the unit had been inspected and approved by a qualified consultant.

START UP CHECK LIST
1.1 Before putting any fan into initial operation, the manufacturer’s instructions should be followed.
Transportation, handling, and installation can cause fasteners to loosen, and cause misalignment
of fan components. Carefully follow this check list when commissioning equipment.
1.2 Lock out the primary and all secondary power sources.
1.3 A complete inspection should be made of all the ductwork and the interior of the fan. Make
certain there is no foreign material which can be drawn into or blown through the fan or ductwork
Appropriate protective measures and safety practices should be observed when entering or
working within these areas. These measures might include the use of goggles, respirators, or
other personal protective devices.
1.4 Make sure the foundation or mounting arrangement and the duct connections are adequately
designed and installed per drawings and in accordance with recognized acceptable engineering
practices and with the fan manufacturer’s recommendations.
1.5 Check and tighten all bolts, fasteners, and set screws as necessary .
1.6 Check the fan assembly and bearings for proper grounding to prevent static electricity discharge.
1.7 Ensure power and drive components such as motor starter, variable frequency drive, or hydraulic
power unit are properly sized, matched , and connected to the fan.
1.8 Check bearing for recommended lubricant and lubrication amount.
1.9 Spin the rotation assembly to determine whether it rotates freely, without hitting anything, and is
not grossly out of balance.
1.10 Inspect impeller for proper rotation for the fan design.
1.11 Check alignment of drives and all other components.
1.12 Check the belt drive for proper sheave selection and installation and make sure the sheaves are
not reversed (excessive speeds could develop).
1.13 Check for recommended belt tension.
1.14 Properly secure all safety guards.
1.15 Assure that all appropriate warnings have been put in place.
1.16 Secure all access doors to the fan and ductwork.

START UP CHECK LIST Continued...
1.17 Momentarily energize the fan to check the direction of rotation. Listen as the fan coasts to a
stop for any unusual noise, identify the source, and take corrective action as necessary.
1.18 Switch on the electrical supply and allow the fan to reach full speed. Check carefully for: a) Excessive vibration b) Unusual noise c) Proper belt alignment d) Proper lubrication e) Proper amperage, voltage, or power values.
f) If any problem is indicated, SWITCH OFF IMMEDIATELY.
g) Lock out the power supply. Secure the fan impeller if there is a potential for wind milling.
Check carefully for the cause of the trouble, correct as necessary, and repeat check list
procedure.
2.0 Even if the fan appears to be operating satisfactorily, shut down after a brief period, lock out the
power supply, and recheck item 1.5 through 1.17 as the initial start-up may have loosened the
bolts, fasteners, and set screws.
3.0 The fan may now be put into operation, but during the first eight (8) hours of running, it should be
closely observed and checked for excessive vibration and noise. At this time checks should also
be made of motor input current and motor and bearing temperatures to ensure that they do not
exceed manufacturer’s recommendations.
4.0 After eight (8) hours of operation, the fan should be shut down and the power locked out. Check
list items 1.5 through 1.17 should be inspected and adjusted, if necessary.
5.0 After twenty-four (24) hours of satisfactory operation, the fan should be shut down (locked out)
and the drive belt tension should be readjusted to recommended tension.
6.0 After commissioning and start-up, the fan should be operated and maintained in accordance with
the manufacturer’s and component manufacturer’s recommendations.
