Existing Facility Anchor Installation
There are many different configurations of footing shapes and sizes to resolve the forces of the
lift; a general case footing that has been calculated for Spectrum is a minimum slab 2’6” Square
by 10” thick anchor centered, with a minimum of four #4 bars each way centered. An engineer
stamped letter can be furnished by Spectrum if requested.
a. From the center of the desired anchor location, using a marking pen or chalk, mark a
square of the dimensions provided by Spectrum Aquatics, or another engineer stamped
footing. This is the concrete to be removed to accommodate the installation of the lift’s
anchor. It is recommended that the anchor be located at least 6” from any expansion
joint, crack, drain, or similar structure in the concrete deck.
b. Use a concrete cutting saw; cut the square out of the existing concrete deck. Using a
heavy/sledge hammer to break the cut section of concrete – remove the section of
concrete from the deck. See Figure 1.

c. Locate a bonding source to bond the anchor. The steel rebar-bonding grid of the pool
deck is the best choice for bonding the anchor. Attach a No. 8 solid copper wire (NEC
Section 680-22) from the bonding bolt on the base of the anchor to the bonding grid.
Note:
d. Place tape over the anchor hole before pouring concrete – not allowing concrete to enter
anchor opening.
If the concrete deck is 8” thick or more or this method is deemed acceptable by
examination, an alternative anchor installation method may be used. In lieu of saw cutting the
concrete deck, a concrete core drill may be employed to cut a 4” diameter hole at the desired
anchor installation location. Epoxy or hydraulic cement may be used to secure the anchor in
place. Make sure the anchor is properly bonded.
