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 REQUIREMENTS

CANOPIES

Avtec hoods are provided with adjustable hanging brackets designed to receive 1/2”
threaded rod with a 1/2” nut and washer. Supporting rods must be connected to all factory
installed brackets. Recommended hanging height is 6’-6” above finished floor for
canopies. Low side wall ventilators should be installed directly upon a Avtec base or on a
rerated wall. If wall mounted, the bottom of the vent should be 36” above finished floor.

ALL AVTEC VENTILATION SYSTEMS MUST BE INSTALLED IN ACCOR-
DANCE WITH NFPA-96, REMOVAL OF SMOKE AND GREASE-LADEN
VAPORS FROM COMMERCIAL COOKING EQUIPMENT.

1. Check all local codes prior to installation. Special requirements may be necessary
depending upon building material construction.

2. Move crated hood to location of installation and very carefully uncrate hood.

3. Raise hood to proper hanging height.

4. Suspend hood from adequate roof supports using 1/2

" threaded rods with nuts

and washers (See Fig. 1).

5. Level hood left to right and front to back.

6. Brackets are provided for hoods which are to be installed end to end or back to back.
Bolt brackets together using 3/8

" bolt through holes provided (See Fig. 2).

7. Install C channel where the ends of the hood meet and install T moldings on front
face of hoods where they join. High temperature silicone can be used to install
channel and T moldings (See Fig. 3).

8. For make-up air hoods, the supply collar with built-in UL listed damper and
air volume damper must be installed per instructions on collar.

9. Provide a removable service door in supply duct near damper (See Fig. 4).

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).
