Step 2B: Align the penstock vertically (without the bottom balancing brackets)
Smaller channel penstocks do not come with “bottom balancing brackets”. Therefore, the
following procedure shall be followed to align the penstock vertically (After “Step 1”).
•
Get two pieces of wood or metal (“Supports”).
•
Rise the slide enough to fit the two supports and secure the supports by closing the slide
(See Figure 4).
•
Proceed with “Step 2”. When the penstock is positioned in the recess, the supports will
maintain the frame invert flush with the invert of the channel (See Figure 5).
CAUTION: Do not use pieces of wood or metal with sharp edges
or with a bad surface condition in order to avoid any damage to
the bottom seal.
5.2 INSTALLATION: FACE MOUNTED IN EXISTING CHANNEL
Required materials:
For the face mounted in existing channel (FM) mounting option, the channel penstock is installed by means of
mechanical anchor bolts
(Hilti Kwilt 3 or equivalent). All the gaps shall be grout filled afterwards and shaped in order to get a
smooth transition.
For detailed information about the type, size and quantity of the required anchor bolts or any other specific installation notes or
materials, please refer to the notes on the “General Arrangement Drawing”.
