WARNING: Disconnect the unit from the electrical power source before attempting any service.
To preserve the UL listing of Terra Fan Filter Units, Terra must configure them for hard-wiring. Cords are dressed to

through the cord grip and connect
to wire port as shown (Figure 6).

Tighten cord grip to secure AC
