Extension Cord Requirements; Flex-Duct Length; Determining Maximum Allowable Leakage - Oriflow Rhino Operating Instructions Manual

Extension Cord Requirements

If you need an extension cord, is it the proper gauge? See Table 2 below for
extension cord requirements.

Flex-Duct Length

Make sure you have enough flexible-duct with your tester for the job. Each tester
includes 3.8 m, which is enough for most applications. Extra lengths of flexible-duct
are available at www.oriflow.com/products.

Determining Maximum Allowable Leakage

To determine the maximum allowable leakage for the project, use ORIFLOW's free
online programs to make these calculations (www.oriflow.com/programs).
Calculations are done for either of the two typical specifications: percentage of
system flow, or leakage class. If the specification uses leakage class, you will need
to calculate the total duct system surface area. Oriflow has a free Adobe form
available to our customers that will calculate duct surface area given the duct shape,
dimensions and length.
