I. INSTALLATION
Note : The MAC 10 e3Filter Unit is completely assembled at the factory with the exception of the optional
¼”(0.64 cm)-20 eyebolts, which can be used when hanging the unit from an overhead structure.
Step 1. Carefully remove the unit from the shipping carton and inspect for any damage that may have occurred during
transportation.(see Figure 1)
Step 2. Wipe down plastic bag and move unit into clean room.
Step 3. If using rigidly supported grid (usually 2” 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 overhead structure with
eyebolts, s-hooks and chain. A roll of high density gasket has been provided for use with ungasketed grids.
Step 4. Have an electrician wire the unit to the appropriate voltage (115V, 220V, 277V AC), according to the wiring
diagram in section IX and local electric codes. To install permanent power, remove the two screws that hold
the 2x4 j-box cover in place. Secure the electrical cable to the j- box. Connect L1 (black conductor) to the
black lead located in the j-box. Connect L2 (white conductor) to the common. Connect the ground (green
conductor) to the ground screw provided in the j-box, use an uninsulated lug for the connection. When the
permanent connection has been made, replace the j-box cover and reinstall the two screws. If optional power
cord was purchased, plug unit into a grounded receptacle.
