INSTALLATION INSTRUCTIONS
WARNING! Before you begin . . .
Whenever you’re working with tools, it’s a good idea
to wear appropriate safety gear: helmet, protective goggles, and gloves. If
you’re working high above the ground, be sure that you have sound footing.
Installing Line-Hide
Your Line-Hide installation will go smoothly if you follow — in
order
— the steps outlined in these instructions: determine layout; install entry fittings and joint bases; install Line
insert Lineset: assemble tube, and assemble joints. When
you’ve finished, caulk the lineset entry and exit points on the
wall to ensure the protection of the Lineset and of the building.
Step 1: Layout
Identify the inlet and outlet points for the Lineset
you’ll be installing within the Line-Hide
product, and determine the simplest
and most appropriate route for the
installation to follow. In most cases you’ll want your installation
to run perfectly vertical and nearly horizontal (a slight grade will
enable condensate lines to drain) and adhere to 90 degree
turns. Sketching your installation on a contractor worksheet or
graph paper will help you to determine how much tubing and
how many elbows, joints, and other pieces you will need.
Try to adhere to a grid defined
by parallel and perpendicular
lines and 90-degree angles
Step 2: Install Entry Fittings and Joint Bases
Most Line-Hide entry fittings and joints (including elbows)
include a base and a cover. Once you’ve determined where
your joints will be, install the bases. If you’re installing on wood,
simply position the base, and fasten it to the wall, using wood
screws. Don’t overtighten, or you’ll risk cracking the plastic.
For installations on a brick wall, mark the location for
each screw, and drill an anchor hole
using a masonry bit; then use
appropriate anchors and
screws.
Tube base;
To attach the Line Tube
base to the wall, first use
the tip of a screwdriver to
make a hole in the central
rib of the base (thin spots
are moulded in to accommodate installation). Then put a screw
through the hole in the tube, and tighten it to the wall. Be careful not to overtighten, for you may distort the tube. For the
smaller sizes (the 60 and 75 series), place screws approximately every twelve inches. For the larger sizes (the 100 and 140
series), use screws approximately every six inches.
Step 4: Install the Lineset
Unwind insulated refrigerant lines, and place into straight portion
of the tube. When installing insulated refrigerant pipe into a corner, adjust the pipe to the shape of the joint, and gently bend the
insulated refrigerant pipe without forcing it. Bending too quickly
can cause kinks in insulated refrigerant pipe and can pinch drain
pipe. Also try to avoid compressing the pipe insulation.
A Saddle Band (NV-S short or
NV-L long) can be used to fasten the insulated refrigerant
pipe, drain pipe, and electric
cable together in the Line
Tube. The saddle snaps to the
central rib of the tube base.
Thread the band through the
saddle and around the piping and cable, and pull it tight. This procedure will help to keep the pipes and wiring in place.
As a general rule, use one saddle band for every three feet (one
meter) of tube.
Step 3:
Measure the distance between the molded stops of each joint
base, and determine the length of tube needed. Line-Hide Line
ube is manufactured in six-and-one-half-foot (two-meter)
T
lengths so some straight runs are fabricated using two or more
lengths of tube and a socket/coupling.

the appropriate length;
then draw a perpendicu
lar guideline across the
tube. Use a hacksaw to cut
the tube along the line, and
then use a file to smooth the
cut edge.

Step 5: Assemble
the Line
When the Lineset is in
position, attach the tube
cover to the base. Slip
the lip on the short
edge of the cover into the trough on the high edge of the base.
Then squeeze the short end of the base while pushing the long
edge of the cover inward so that the lip and the trough engage.
Step 6: Assemble the Joints
With the Line Tube completely assembled, return to each joint,
and complete assembly
base; line up the holes; then secure cover to bases with the
stainless steel screws provided.
