i. Preparation for Installation
This manual should be carefully read before starting the preparation and
installation of the air cleaner. The installation should conform to all local
ordinances associated with building codes and electrical codes required for
the unit. Authorities having jurisdiction should be consulted before
installation is made. If there are no local codes, the installation should
conform to the National Electrical Code.
Factory-designed access to all electrically charged high voltage components
contains electrical interlocks for the safety of operating personnel. Any
additional access that may be provided in the system, where there is access to
high voltage, must be equipped with such interlocks. Interlocks are readily
available from the factory. For maximum air cleaning efficiency, your air
cleaner should be located as specified by your Trion representative. The unit
can be either wall-mounted or chain-hung.
New Unit Inspection
Immediately, upon receiving the unit, carefully examine the package for damage
during transit. If the unit is damaged, contact the last carrier for claim
filing and contact your Trion representative immediately. While unpacking the
unit, look for concealed shipping damage. If there is damage, it should be
reported to the last carrier for claim filing.
Operation
What is an Electronic Air Cleaner? An electronic air cleaner is a high-
efficiency contaminant collector designed to remove up to 95% of the dust,
smoke, liquid aerosol, and other pollutants from the air passing through it.
How It Operates
The T2002 and T3003 units require a fan to move the air. After passing through
a prefilter, the particles in the air are given an electrical charge supplied
by the power supply. As the particles enter the collector cells, these charged
particles are attracted to and collected on grounded collecting plates.
Typical Electronic Cell Operation
Unit Operation
Control Switch (A)– The control switch is located on the cell access
door. It controls the operation of the power pack. The control switch should
be in the “OFF” position when the cell access door is open for maintenance of
the unit.
Indicating Light (B)– The light located adjacent to the control switch is
an indicator of the performance of your electronic air cleaner. When the
control switch is “ON” the indicator light should glow. If the light does not
glow or if it continually flickers and is accompanied by a continual snapping
or arcing noise, the air cleaner requires attention and may need to be
cleaned.
Cell Access Latches (C)– The cell access latches are located on the door
near the intake end of the unit. To open the cell access door, lift and turn
the latches counterclockwise.
Arcing (snapping or cracking noise)– An occasional arcing noise may be
emitted from the air cleaner. This is a normal occurrence caused by
exceptionally large pieces of dirt etc entering the collecting elements. In
addition, an arcing noise accompanied by a flickering carrier of the
indicating light may be noticed after washing the cells. Should this occur,
allow more drying time. Also, see “Troubleshooting Chart” for additional
causes of arcing. The louvers on the grill are adjustable so the direction of
airflow can be controlled as desired.
NOTE: The unit is equipped with an interlock switch for your safety. The
unit will not operate if the cell access door is not closed securely.
Ducting Application
To maintain the selected cleaning efficiency, it is important to ensure that
the total air volume (capacity in CFM or m³/hr) is uniformly distributed
across the entire face area of the unit. The metal mesh filters, perforated
plate, or mist suppressors provide some resistance to affect even air
distribution. However, since most air ducts are designed to handle air
velocities greater than the rated velocity of the air cleaner, it is necessary
to properly transition any attached ducting. If possible, a contraction ratio
of 1 in 3 approximately 20°) should be maintained. If space prohibits turning
vanes, air baffles or other means may be utilized. Ducting–were attached to
the cabinet collars–should be gas keyed, caulked, or otherwise made
watertight.
ii. Installation – Read Thoroughly
- Carefully unpack unit from shipping crate or carton and examine for damage in shipment.
- Remove ionizer/collector cell(s), prefilters, and after filters.
- In the event of hanging a ducted system including a filter, it is your responsibility to measure the unit and carefully choose and devise duct rods and chains to support the weight of the unit.
Liquid Aerosol Application Installations
The unit is equipped with a sump, and drain hole sized to accept a ½” NPT
fitting.
For the collection of liquid contaminants:
- Install drain fitting to allow for the attachment of a liquid collection cup/drain hose. A drain fitting is available from your representative. An “S” trap is required in the drain hose to ensure proper drainage of the collected liquid.
- Raise the front corner of the unit, opposite the drain corner, ½” (13 mm) to enable the collected liquid to flow to the drain sump.
Contaminants to be collected, such as oils in a vaporous state must be condensed into the particulate form prior to entering the ionizing collecting cells in order to maintain the anticipated efficiency. Gases, vapors, or any nonparticulate cannot be precipitated and will therefore pass through the air cleaner. Any condensing that takes place downstream from the air cleaner defeats the purpose. Similarly, heavy concentrations of water vapor, or other matter that becomes highly conductive when condensed, must be prevented from entering and/or condensing in the collecting elements to prevent electrical arc over and short.
Electrical Installation
All units must be wired directly in the junction box on the access door side
of the unit. Use NEC Class I wiring methods. Size branch circuit protection in
accordance with the NEC. Refer to the appropriate enclosed wiring diagram in
the attached figures.
Exercise all the normal precautions when working with high voltage and
comply with NEC and all appropriate local codes.
Check Out for System Start-up
When the installation has been completed, assure that the equipment is ready
for start-up by checking the following:
- All construction debris is removed from the ionizing collecting cells, drain connections, and ductwork.
- The drain line from the drain basin is clear and completely connected to its point of termination.
- Supply line power is available and electrical wiring is completed to the junction box.
iii. Maintenance
The following instructions are for use by qualified personnel.
WARNING – RISK OF ELECTRIC SHOCK
These serving instructions are for use by qualified personnel only. To reduce
the risk of electric shock, do not perform any servicing other than that
contained in the operating instructions unless you are qualified to do so.
Factory-designed access to all electrically charged high voltage components
containing electrical interlocks for the safety of operating personnel. Any
additional access that may be provided in the system, where there is access to
high voltage, must be equipped with such interlocks. Interlocks are readily
available from the factory.
Cleaning
To maintain optimum collection efficiency, the prefilters, and
ionizer/collector cells should be removed periodically and soaked in a
solution of hot water and Trion Tridex detergent for 2 to 4 hours, rinsed
thoroughly, and then air dried completely before reinstalling in the unit. The
frequency of cleaning is dependent on the type of contaminant being collected.
Liquid aerosol requires less cleaning while welding smoke may require more
frequent cleaning.
Trion Tridex Detergent is specially formulated for use with Trion electronic
air cleaners. The use of other cleaners and detergents, not specifically
approved by Trion, can cause possible failures in the unit and will void any
and all warranties on our equipment.
Wash Ionising/Collecting Cells
Do not use high-pressure steam cleaning equipment to clean cells. The excessive heat and pressure will cause the plates to warp and in turn possibly cause excessive arcing.
- Turn the control switch “OFF” and disconnect the power to the unit.
- Open the cell access door.
- Remove ionizer/collector cells and wash in hot water with detergent. If the collected contaminant is of an extremely dry nature, it can be blown off the cells with a pressure hose or by gently tapping the end plate of the cell.
- Remove the mechanical prefilter. Remove collected dust or lint by vacuuming or brushing. Wash with warm, soapy water.
- Rinse all components thoroughly in warm, clear water and allow to drip dry completely.
- Replace prefilters and ionizer/collector cells. Ensure the airflow arrows point in the direction of airflow (towards the blower).
- Close the access door, and reconnect power to the unit.
- Turn the control switch to “ON”. If arcing occurs or the indicating light flickers, the components may still be damp. Turn the unit OFF and allow the cells to dry completely.

Part 2 – UV-C
i. Introduction and Purpose
The UV-C system has been specifically rated to suit the design airflows for
the ventilation supplied. If it is necessary to change the ventilation system
for any reason then Trion should be consulted on the continued use of the UV-C
system.
This manual provides information on the safe operation and maintenance of the
Trion UV-C and Ozone system.
A pre-commissioning checklist is shown in Appendix A. This UV-C component is
designed for the removal of odor and grease from commercial and industrial air
extraction systems and should always be used in combination with suitable
prefiltration depending on the grease and smoke content of the treated air.
ii. Operation
The UV-C system must not be operated without the extract ventilation fan
running. The UV-C lamps generate small amounts of ozone, which is heavier than
air and an irritant.
To prevent the back-flow of ozone into the kitchen it is recommended to allow
the fan to run on for up to 10 minutes after the Techniclean UV-C unit is
switched off.
The UV-C system should be set up to run automatically whenever the extract
ventilation fan is running. The system should be interlocked with the main fan
control, for example via an AC-3 rated pressure differential switch. To reduce
the impact of condensation it is recommended that the fan is left running for
30 minutes after cooking operations have finished. A class D MCB must be used
for surge protection purposes.
Repeated rapid switching on and off of electronic ballasts can lead to
premature failure. Switching the UV-C lamps on and off reduces their useful
operating life and each “on-off” cycle can reduce the life by one hour.
Unnecessary switching should therefore be avoided.
After ignition UV-C lamps require a start-up period (typically 20 minutes) to
reach full output. It is essential that any replacement lamps that are
installed have the same UV-C and ozone performance characteristics as the
originals if the design performance of the equipment originally supplied is to
be maintained. See section V for ordering spares.
In order for the UV-C system to operate as designed it is important that the
UV-C lamps are kept clean and free from grease contamination. Maintenance of
this unit is to be carried out only by Trion-approved contractors. Always
disconnect power to the equipment, and unplug it before performing any
maintenance operations
iii. Maintenance
Trion or other experienced contractors approved by Trion should only carry out
these maintenance activities. Monthly, bi-monthly, or as experience suggests,
carry out the following routine maintenance:
- Switch off and isolate the main ventilation fan.
- Switch off the UV-C lamps at the control panel and isolate and lock off the power supply.
- Check the condition of the UV-C lamps by removing the insert unit(s).
- Clean the lamps as set out below.
- Re-install the insert units replace the front cover and switch on the ventilation and UV-C systems.
Annual Maintenance
The UV-C system should be cleaned and checked annually as part of a planned
maintenance program. Trion or other approved contractors should carry out
annual maintenance under a planned preventative maintenance agreement. UV-C
lamps have an operating life of 10,000hrs after which they should be replaced.
Lamp Cleaning
Check that the end caps supplying power to the lamps are positively in place.
During the UV-C lamp cleaning process, it is possible for the tubes to move
and for the end caps to become disconnected.
The quartz glass used for the UV-C lamps is brittle and may break if knocked
with sharp tools or rings etc.
During the normal operation of the UV-C lamps, a white powder will accumulate
on the surface of the tubes. This white powder is inert ash and is a product
of the cold combustion process.
Any surface contamination will reduce the output of the lamps and limit their
performance. It is essential that the UV-C lamps and all polished surfaces of
the insert unit frames are clean.
The lamps can be cleaned with a damp cloth using warm water and detergent. The
lamps should then be wiped down with fresh clean water and dried using a lint-
free cloth. The lamps should then be wiped down with a clean rag dipped in
100% isopropyl alcohol. This liquid solvent can be purchased from a chemist or
an industrial chemical cleaning supplier.
If the deposit on the tube proves to be difficult to remove or has been
contaminated with grease a commercial heavy-duty detergent should be sprayed
onto the lamp and left to soak for 10 minutes and then rinsed off. Follow this
with the normal cleaning operation as described above.
iv. Handling and Disposal of UV-C Lamps
The lamps are made from quartz and should be handled as glass. The lamps
contain traces of mercury. Any droplets of mercury and broken lamps should be
disposed of safely in accordance with HSE regulations.
Wear protective gloves when handling failed, broken, or damaged UV-C lamps.
Remove the connection end cap or caps from the UV-C lamp. Carefully remove the
UV-C lamp by withdrawing it through the end box or housing. The lamps can
become stuck to their grommets and care should be taken to ensure that the
UV-C lamps do not break when handling.
Ensure that failed lamps and any broken lamps are disposed of safely using
facilities normally provided for fluorescent lamps.

Appendix A. Pre-Commissioning Checklist
The following items should be checked following the mechanical installation of the kitchen canopy, ductwork, and fans. Ideally, there will be commissioning certificates available.
Installation
The unit is designed to be installed in the extraction ducting of a commercial
kitchen canopy, located downstream of the canopy and upstream of the fan, in
accordance with the Installation, Operating, and Maintenance Manual.
Electrical Supply
The unit must be interlocked with airflow and protected with a Class D MCB (by
others). The power supply is to be located within 1m of the unit (by others).
Checklist for ductwork and fans:
- Check ductwork has been blown clean.
- Open inspection doors and check for construction debris.
- Check ductwork run from canopy to vent is complete, supported, and inspection doors closed.
- Check fans run in the correct direction and without excessive vibration.
- Check any fan interlock requirements.
- Review air flow balancing results to check correct flows to each canopy/duct run.
- Check gas supply to appliances turn off when extract fan turned off.
- Check correct make-up airflows to each area of the kitchen.
- Check power supply available to UV control panel.
- Check protection on the client’s power supply is Class D MCB
Checklist for canopy installation:
- Check grease filters are correctly installed
- Check ballast boxes/plates are accessible and correctly positioned
- Check plastic pipes to air pressure switches are correctly connected
- Check safety strap on insert units attached
On some sites, there may be additional activities by other trades after the canopies have been installed and checked. A final check is then required to see below:
Final Check List
- Check fire suppression pipework, and telephone cables BMS cables do not interfere with access to lamp frames, air supply plenum, or ballast boxes.
- Check appropriate access panels or ceiling tiles are available allowing access to ballast boxes in the ceiling void.
When the above checks are complete the UV system is ready for commissioning.
See Appendix B for a maintenance checklist.
