TYPES OF SYSTEMS
This manual covers three of the basic types of systems offered by Avtec:
• Baffle Filter
• Modular Grease Extractor
• EcoArch UV
BAFFLE FILTER SERIES
Baffle Filters ventilators are listed by UL and are built in accordance of NFPA-96 for use
with UL listed extinguishing systems for duct hood protection. They utilize UL classified
removable baffle filters to extract grease and provide a limited barrier. The canopy contains
a hidden grease trough and removable cup. Surface, plenum and duct collar extinguishing
systems may be factory supplied.
MODULAR GREASE EXTRACTORS SERIES
Extractor ventilators are listed by UL and are built in accordance of NFPA-96 for use with UL
listed extinguishing systems for duct hood protection. These models utilize high velocity
removable grease extractors. The canopy contains a hidden grease trough and removable
cup. Surface, plenum and duct collar extinguishing systems may be factory supplied.
ULTRAVIOLET (UV) SERIES
The EcoArch Energy Efficient Ventilation UVc is a door assembly integrally installed in the
exhaust plenum of an EcoArch canopy, consisting of UVc filtration system designed for
use in the ventilation control of commercial cooking operations of listed hood systems. A
depiction of this unit is indicated at left.
The UVc filtration system consists of a Heraus manufactured UVc and Ozone producing
lamp used to reduce exhaust odors and grease deposit emissions before they enter the
exhaust duct system. The UVc light waves and ozone producing lamp breaks the grease
particles into smaller molecules which allow an Ozone reaction to occur chemically. Like
combustion, high temperature separates the O-atoms in atmospheric Oxygen which then
bonds to the grease molecule causing oxidation. Similarly, in UVc technology, the extra
O-atom in the Ozone splits from the ozone molecule and attaches itself to grease molecule
causing oxidation but without the high temperature, which results in the reduction of duct
cleaning, cleaning costs and risks of potential grease fires.
The EcoArch Energy Efficient Ventilation UVc is manufactured with Type 201 Stainless
Steel; but, alternatively can be constructed using 200, 300 and 400 series stainless steel
without adversely affecting the UVc filtration system capabilities.

Installation Instructions
ECOARCH CANOPIES EQUIPPED
WITH UV ASSEMBLY
If your EcoArch hood comes equipped with an UV assembly please refer to the following
steps.
General CAUTIONS & Guidelines
• Installation of UV Exhaust canopies must be completed by HVAC ventilation system
contractors or employees trained and qualified to do ventilation hood and exhaust
system installation.
• All Fire Suppression System work must be completed by contractors or employees
trained and qualified to do commercial kitchen exhaust hood fire suppression system
installation.
• All work must conform to local and national building and NFPA 96 codes and
requirements.
• This document covers installation of the UV mechanical components and electric
connections.
• Electric work must be performed by licensed contractors in accordance with the
current National Electric Code and all national, regional and local codes that apply.
• Read and review these instructions BEFORE attempting to install this unit. For
best results, follow the installation sequence…as described.
Follow steps 1-7 as outlined for standard EcoArch canopy installation on page 5.
8. Install grease extractors as shown in (fig. 5 on pages 7-8). Be certain the extractors
are seated properly as the UVc bulb will not operate without safety contacts being
engaged.
9. Open door on face of canopy by twisting the supplied locking handle in order to install
UVc bulb per supplied diagram. Be certain to close door tightly and engage handle latch
in order to engage safety contacts. UVc bulb will not operate without safety contacts
engaged.
10. Check to see that pressure switch tubing is installed on the low port of switch and the
port on top of the hood located in the s/s enclosure.
11. Install power to UV system as described in Electrical section on page 9. See wiring
diagram (fig. 6 on page 10-12).

ALWAYS USE CAUTION WHEN SERVICING
THE UV SYSTEM.
DANGER!
PLEASE USE CAUTION WHEN INSTALLING
OR SERVICING THE ELECTRICAL SYSTEM
FOR THE UV HOOD. ELECTRICAL SHOCK CAN
CAUSE SERIOUS INJURY OR EVEN DEATH!!!
ELECTRICAL WORK SHOULD ONLY BE DONE
BY QUALIFIED PERSONNEL.
PLEASE ADHERE TO ALL ELECTRICAL
NATIONAL, STATE, AND LOCAL CODES.
Install Power
Locate the relay box on top of the hood. Inside the relay box locate terminal strip 1 (TS-1).
On terminal strip 1 connect a 115/60/1 – 20 amp service to terminals 1 and 2. THE 120V
POWER SOURCE CONNECTED TO THE RELAY BOX IS FOR THE HOOD CONTROL SYSTEM
AND UV LIGHTS ONLY. THIS POWER SOURCE IS NOT FOR THE CANOPY LIGHTS OR FANS.
Those systems require separate power sources.
Control Panel
The control panel will be mounted on the hood or remotely. If the control panel is mounted
on the hood no installation is required. If the control panel is located remotely then
installation is required.
Remote Located Control
• Locate terminal strip 2 (TS-2) in relay box located on top of the hood. This is where
the UV light switch will terminate. THE POWER AT (TS-2) IS 115V/1/60. Connect one
side of the switch to terminal 1 and the other side of the switch to terminal 2. Please
make sure the switch is connected to ground.

Should be checked weekly for grease build up and cleaned with strong detergent if
necessary.
4. Grease Collection Receptacle
Should be emptied at least once a day and cleaned daily with a strong detergent.
5. Hood Canopy
A. Inside hood canopy should be wiped down as needed. The area at the exhaust
intake openings should be wiped down daily.
B. Inspect inside of extraction chamber at least weekly to insure proper cleaning and
that the trough and access door are free of foreign matter.
6. UV Preventative Maintenance
Clean the UV lamp at the same time the grease extractors are being cleaned (or daily),
wipe down the UV lamp exterior using a dry towel and a non-detergent cleaning agent
such as sanitizing solution or white vinegar.
IMPORTANT: Do not allow cleaner to run into lamp fittings or socket enclosures.
IMPORTANT: UV System will not work properly without daily cleaning of the UV lamp.
