TSI Incorporated Alnor LoFlo Balometer Mode D'emploi page 5

When using the LoFlo Balometer to check air flow at
ceiling diffusers, make certain that you can safely raise
and hold the unit while making measurements. Be
especially careful when working on a ladder.
Observe all necessary precautions so that the unit does
not become caught in moving machinery or touch any
exposed electrical wiring.
Hood Setup
1. Locate the four (4) aluminum channels for the
hood and position them into a square with the foam
facing up. Slide the "U" opening on the channel
end (Fig. 1) and corner bracket toward the brass
eyelets until you feel it latch.
2. Continue with the other two channels until you
have a square frame that is locked tightly in all
four corners.
3. Locate the hood for the frame size you have
assembled.
4. Position a corner seam of the hood onto the corner
of the frame. Stretch the nylon hood to an adjacent
corner until the hood corner meets the frame
corner.
5. Push the elastic cord into the channel along the
side of the frame.
6. Repeat steps 4 and 5 until the hood assembly is
complete and ready to mount onto the base.
7. Place hood on a table or clean floor with the base
inside the opening. Pull the hood over the base.
Rotate the hood assembly until the metal cups are
above the spring-loaded pins.
