MAC 10® LEDC

4x4 Fan Filter Unit

Installation & Service Manual

■ Installation

Note: The MAC 10 LEDC Fan Filter Unit is completely assembled at the factory with the exception of the optional ¼” (0.64

cm)-20 eyebolts that are used when hanging the unit from an engineered design support system and installation of the HEPA/

ULPA lters (eyebolts not included and need to 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). Using the two handles attached to the lid, two workers minimum, are required to lift the unit from

the box.

Note: When ordering RSR and RSRE

units, the HEPA lters will be shipped

separately to be installed into units
after the fan box has been installed.

Figure 1: Unboxing

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

If using a exible 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: Conrm fan dimensions to match T-grid dimensions.

Step 2.1. It is recommended that you front load your MAC 10 4x4 to your T-Grid system by running your main T-Grid and two

cross Ts (install fan box into grid), then running your main T again (see Figure 3).

Step 2.2. If using a support grid, continue...

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 eld connection. Verify correct single-

phase power, before energizing units.

Step 5. Turn on the power using the two position rocker switch (ON/OFF) located on the electrical box. For RSR/E units, let

the unit run for a few hours to purge off particulate that may be adhered to the inside of the unit before installing the lters. Do

not run fan at full speed as this may cause overload condition.

Note: Your fan lter has been shipped separately.
