Installation & Operation

Installation

Note: Titus fan filter units are completely assembled at the factory with the exception of the optional ¼”-20 eyebolts

that are used when hanging the unit from an engineered design support system and installation of the HEPA/ULPA filters

(eyebolts not included and can be ordered separately, p/n 222449-001).

Step 1. Carefully remove the unit from the shipping carton and inspect for any damage that may have occurred during

transportation (See Figure 1).

Note: When ordering FFDR and

FFDRA units, the HEPA filters may

be shipped separately to be installed

into units after the fan box has been

installed.

If using rigidly supported grid (usually 2” (50 mm) or wider), raise unit through ceiling and lower onto the gasketed grid.

If using a flexible grid (typically supported with wires), the unit must be secured to an engineered design support system

with s-hooks and chain. Screw the four eyebolts into the nutserts on the lid assembly before lifting into an overhead position

(see Figure 2) Note: Confirm fan dimensions to match T-grid dimensions.

Step 3. Raise the unit and secure it into place using the chosen support system method suspended from a structural support

bracing.

Step 4. Have an electrician wire the unit to the appropriate voltage, according to the wiring diagram (page 17), and all national

and local electrical codes. All units are equipped with a three position terminal block for field onnection. Verify correct singlephase

power, before energizing units.

Step 5. Turn on the power using the two position rocker switch (ON/OFF) located on the electrical box. For FFDR and

FFDRA units, let the unit run for a few hours to purge off particulate (if filters are shipped loose) that may be adhered to

the inside of the unit before installing the filters. Do not run fan at full speed as this may cause overload condition.

Note: Your fan filter may have been shipped separate. Controls have been shipped separately.
