OPERATING THE UNIT
BEFORE OPERATING THE UNIT
Inspect and tighten any HEPA filter retaining nuts that may have loosened during transportation. Inspect the filters for
any material or structural damage prior to use and replace any damaged filters before operating the unit. When
removing any filters prior to operation, always put them back in place with the airflow indicator on the filter housing
oriented in the proper direction (if applicable).
As with any air filtration system, external airflow losses not attributable to the air filtration unit will reduce the airflow of
the system. The following recommendations can minimize airflow losses created by external static resistance.
1.
Always use the minimum length of ducting possible with the fewest possible number of turns and bends.
2.
Rigid metal ducting creates less turbulence and consequently less airflow loss than flexible ducting. Regardless of the type
of ducting used, rigid, “sweep
-
type’,
radiused connections should be used for all turns and bends.
3.
If flexible ducting is used, it must be kept as taut as possible to avoid flattening.
4.
Louvers, dampers, and other external control devices should be sized to provide the equivalent open area to the cross-
sectional area of the exhaust ducting.
5.
For negative or positive pressure applications, the total volume of air supplied to the room must be lower than the volume
of air exhausted by the air filtration unit. The minimum recommended differential is the greater of 100 CFM or 10%.
Pressure levels should be continuously monitored. Note: If the air supply to the room is not controlled, sufficient negative
or positive pressure might not be achieved
.
LOCATION OF THE UNITS AND MODES OF OPERATION
The TRI-KLEEN portable air filtration units can be operated in the following modes:
1.
Negative pressure
. Unit is inside the containment room. All of the filtered air is exhausted to an external environment.
2.
Full in-room recirculation.
Unit is inside the containment room. All of the filtered air is recirculated back into the room
through the exhaust outlet.
3.
Positive pressure
. While possible, the TRI-KLEEN 500UV BR was not designed for this purpose. The unit is
outside
the
containment room. All of the filtered air is exhausted to the containment room and creates a positive pressure in that
room
.
TRI-KLEEN portable air filtration units should be positioned at a maximum distance from the main door to the room in
which they are used. For negative or positive pressure applications, the units will have to be ducted in order to create
the pressure differential. Before the unit can be ducted, the sound baffle attachment on the top of the unit must be
removed by loosening the two screws inside the baffle, and sliding the baffle towards the back of the machine. After
the baffle has been slid towards the back, lift up on the attachment to remove the baffle and expose the exhaust grille.
After the baffle has been removed, ducting can be connected to the unit. The units can accept 12" x 8" (30.5 cm x 20.3
cm) rectangular ducting or an optional (not included with the unit) round exhaust collar that accepts 8" diameter rigid or
flexible ducting is available. This optional exhaust collar fits over the exhaust grille on the unit and is secured by 4
screws.
