****WARNING****

Fire Suppression Systems

Extreme caution should be exercised when this unit

is installed in applications that are collecting

volatile or potentially flammable contaminates such

as cooking grease and petroleum based oils.

Trion strongly recommends a fire suppression

system be installed in the ductwork and on the

Model 75 in cases where these contaminates are

collected on the cell plates and collect on the

attached ductwork.

Contact the factory for questions or concerns

regarding a fire suppression system.

3. Outdoor Installations

Requirements for outdoor protection vary in accordance

to climate and equipment component arrangement for

the particular job. The best approach, for equipment

protection, is the construction of a heated shed or

building over the installation. As an alternative, the

installing contractor should treat the equipment as

required to meet the specific needs. Detailed

discussions of the Model 75 components are as follows,

using a rooftop installation as an example (refer to

Figure 3):

Adjoining Duct Work (not supplied by Trion)

The ductwork located on the air entering side of the

cabinet, between the point where it enters the roof and

the cabinet, must be air tight to prevent the entrance of

moisture, especially if it is under negative pressure. It

must also be adequately insulated or other means taken

to prevent the formation of condensation through

temperature change. Condensation will short out the

ionizing-collecting cells. Insulation must be of the

outdoor variety.

Trion Model 75 Cabinet

The access doors on the Model 75 cabinet are gasketed

and the unit is basically sealed against air leakage. The

paint finish (epoxy) is for interior and exterior use. Like

the air-entering duct, the cabinet must be insulated or

other means taken to prevent condensation from taking

place, which results in electrical shorting of the ionizing-

collecting cells. Insulation, when employed must be

suitable for outdoor applications and when applied,

consideration given to all access door openings and

electrical interlock box covers.

Controller/PWM Power Supplies

As the controller/power supplies are designed for

remote mounting, they can be, in many cases, located

indoors and still be reasonably close to the main

cabinet. If located outdoors with the cabinet, it must be

weather protected.

Drain Line

The drain line, located under the ionizing/collecting cell

access door at the lowest point of the Trion cabinet

drain pan, should be piped with as short a run as

possible to the heated interior of the building.

Preferably, straight down from the drain pan supply

through the floor. The normally recommended drain line

trap, to seal off the cabinet from the drain against the

system pressure, should be located in the heated

interior. If not installed in this manner, heat wrap or

other means should be employed to prevent freezing.

Clean-outs are recommended to be installed in all drain

lines.

SECTION II INSTALLATION

FOR THE INSTALLING CONTRACTOR

1. Unpack and Inspect

At the time the unit is received, all shipping containers

and their contents should be examined for damage. Any

damage occurring in shipment must be immediately

reported to the carrier, an inspection report completed

and a claim filed at the receiving point.

The unit cabinet is shipped completely assembled and,

where size permits, the ionizing-collecting cells are

shipped inside the cabinet. On large units, the upper tier

of cells may be shipped in separate containers. The

controller, and other separate accessories are shipped

in the containers as noted on the packing list.

2. Position Air Cleaner Cabinet

To reduce weight for ease in handling, remove the pre-

filters, after-filters and the ionizing-collecting cells from

the cabinet, and place them safely aside. Position the

cabinet in the designated location giving consideration

to the following points:

(a) Provide sufficient clearance in front of the access

doors for ionizing-collecting cell and mechanical

filter removal. A minimum of 39 inches is

required. (see figure 5)

(b) Level the cabinet to assure proper drainage from

the drain pan.

prearranged, the direction of airflow through the

cabinet may be either from the right or the left.

When the ionizing-collecting cells are reinstalled,

the directional arrows on the cell end plates must

concur with airflow through the cabinet. If mist

suppressors have been specified, they are to be

installed on the air entering side of the unit.

After the cabinet has been properly located, it may be

secured into place at the predrilled factory mounting

pads either by bolting or welding.

3. Connect Adjoining Duct Work

Depending on the application, the installation plan may

or may not call for adjoining ductwork on the air entering

and/or air leaving sides of the cabinet.

When adjoining ducting is to be installed, the bottom of

the horizontal duct runs should be relatively flat and
