Base weight is based on 48 inches (121.92 cm) hood length. For each additional foot of hood in length, add 55 lb/ft (24.95 kg/m) in weight of hood and 67 lb/ft (30.39 kg/m) in weight of hood filled with water.

Example of a 10 foot hood:

Dry: 48 inch width x 120 inch length

=440 lbs. + (6 ft. x 55 lb/ft)

=440 lbs. + 330 lbs.

=770 lbs.

With Water: 48 inch width x 120 inch length

=488 lbs. + (6 ft. x 67 lb/ft)

=488 lbs. + 402 lbs.

=890 lbs.

DANGER

The maximum weight (weight with water) should be used for the maximum weight of the hood to ensure the ceiling structure can support the weight of the hood when filled with water.

Profile of Hood

Carefully slide the hood onto the lifting skid. The lifting skid should be used to lift the hood into its final position. If the lifting skid is not used, the hood will be damaged during the installation process.

CAUTION

To ensure proper structural support, all hanger brackets must be used for hanging the hood.
