3.3 Ceiling Mounting

The box ventilator can be mounted with plumber’s strap or threaded rod with nuts and washers, or it can be placed on support

legs (included). As Fig. 6 illustrates, the ventilator can be placed in virtually any position or direction, except with the motor

pointing down. When placing the venter on the support legs (1), the vibration dampers (4) should be used and secured by nuts

(2).Thesupportlegsareattachedtothebottomoftheventerusingtheenclosedsheetmetalscrews(3).Inthisconguration

the venter is typically placed on a shelf hung from a wall.

If hanging the venter from the ceiling, threaded rods should be used. Attach the support legs (1) to the bottom of the fan and

secure with the sheet metal screws (3). Do not use the vibration dampers. Instead use the holes on the top of the legs for the

threaded rods and secure these with the nuts (5).

3.4 Connection to Duct

In order to achieve optimal perfomance and energy consumption, the duct must be installed as shown in Fig. 7 and the

distances observed. If transfer of vibrations is a major concern special vibration dampening connectors (FLF) should be

installed. These are available from ENERVEX. If a duct is not connected, a safety screen (accessory), as shown in Fig. 8, must

be installed. Make sure the sizing of the ventilator takes the resulting static pressure loss into account.
