Hint: Create clamps from extra tubing to hold low-

voltage wire in place.

Masonry or concrete walls.

If you have to run tubing through masonry or concrete

walls, rent a hammer drill and/or masonry hole saw.

Run the tubing through and patch the hole once you’re

up and running. Before drilling, check local building

codes for special ﬁ rewall penetration regulations. The

code also should tell you if steel tubing is required.

Installation Step 7:
Install the power unit.

Attach the power unit to the wall with the bottom

screws of the mounting bracket located 48" (1.2m)

above the ﬂ oor to allow easy removal of the dirt

canister. For proper motor cooling, there must be at

least 12" (30.48cm) between the unit and the ceiling.

Do not install the power unit where the ambient

temperature regularly exceeds 120 degrees

Fahrenheit (48.9 degrees C).

If mounting on plaster, wall board, or panel walls,

be sure mounting bolts enter studs. If mounting on a

block or concrete wall, drill the holes with a masonry

bit and insert plastic or lead anchors. As an alternative

to mounting on concrete walls, suspend 2" x 4" (5.1cm

x 10.16cm) studs or plywood from overhead.

Connect tubing from additional inlet valves to the main

trunk line using 90 degree sweep tee elbow ﬁ ttings.

(Fig. 07) and use clamps to hold the sections in place.

Be sure to install the sweep tee ﬁ ttings so the sweep

is toward the power unit (Fig. 08). Always run branch

lines from the sides or top of the main trunk line never

out of the bottom because this will create a trap for dirt

to fall into.

String the low-voltage wire along as you assemble

the tubing. Join or splice low-volt wires with wire

connectors at each junction or branch in the tubing.

To make sure the polarity is right, always attach wires

of the same color to each other…typically copper-to-

copper and silver-to-silver. Proceed until the tubing

system is complete.
