AAF FLATBANK SIDE ACCESS FILTER HOUSING

INSTALLATION AND OPERATION INSTRUCTIONS

CAUTION… Review these instructions and all safety procedures with your safety officer.

INSTALLATION OF HOUSING

1. Be sure position of housing access door(s) and direction of airflow

is correct prior to connecting ductwork.

- A minimum of 3 feet clearance is recommended for filter change out -

2. The housing should be permanently connected to the ductwork by

welding, bolting, or riveting. The housing to ductwork connection
should be suitably sealed with caulk or gasket material to
preclude leakage.

3. Following installation of the housing, the system should be

“Vacuumed out” or “Blown-Down” to remove construction dust,
etc., before installing the filters.

INSTALLATION OF FILTERS

1. Leave the filters in the shipping cartons until transported to the

proper housing location. Do not unpack the filters until time of
installation. Unpack the filters taking care not to cause damage.

2. Open the housing access door by unlatching the positive pressure

trip lock latches. The housing door is hinged and can be swung
open completely.

3. There are no locking mechanisms for the filters on the FlatBank

housing.

4. Load filters into the housing insuring that the filters are installed

in the correct position. When airflow is horizontal, filter pleats
must run vertical. Gently but firmly push the filter until it
touches the back of the housing or as far as can be reached. On
multi-wide filter housings repeat the procedure for each filter
until all filters are installed.

5. Swing the access door to the closed position and latch the door

securely. The filters are locked into position when the access door
is secured.

6. Filter change out is carried out in the same manner when filters

reach their design final resistance. Spent filters are removed and
clean filters re-installed in the manner described above.
