EXISTING CONSTRUCTION

From the attic down

In order to find where to drill the holes for the branch lines into the plates, establish a

reference point for the Inlet valve by measuring from the center of the intended inlet

valve location to the nearest corner of the room in which the inlet is to be located.

Find this corner from the attic by peeling back the insulation to expose the top plate.

Measure the same distance you measured below from where the top plates form that

corner (illustration 1). You should now be in a straight vertical line directly above the

Inlet valve location. Remember whether you measured your reference point from

the inside or outside corner.

Drill a 2 1/2" hole into the center of the top plate. After you have completed this,

you can visually re-check, with the use of a flashlight, that the space between the

studs is free of obstruction.

As our illustration shows, you will be working in a confined space with very little head

room. Use any number of extension drill bits to enable you to get to the intended

location of the inlet valves (illustration 2).

Measure and cut pipe from the plate to Inlet valve hole below and feed pipe through

hole into space between wallboard.

It is important that you have all the necessary tools with you in the attic to save you

avoidable trips through the small access openings, through which attics are commonly

accessible (illustration 2).

If, due to lack of adequate vertical space, the entire length of pipe can't be inserted

in one piece, then shorter sections can be cut and glued together with the use of

couplings and fed into the hole in the top plate section by section until it reaches

the inlet valve opening.

Note:

IT IS EXTREMELY IMPORTANT TO VERIFY THAT THE WALL DOES NOT

CONTAIN ANY ELECTRICAL CONDUCTORS WHICH MAY INTERFERE WITH

THE DRILL BIT.

YOU ARE NOW READY

FOR THE INSTALLATION

OF THE MAIN LINE.

Illustration 2

The main line connects the entire system from the inlet valves to the power

unit. It carries the low-voltage wire along its entire run. During the layout process

you checked carefully for possible obstructions along the intended run, such as

double joists, ducts, electrical wiring or water lines. By-pass these obstructions

as per our illustrations.

Glue main line fittings to the exposed branch pipes above the plates. Make sure each

fitting points in the direction of the power unit. Measure and cut the pipe lengths for

the main line and glue into hubs of fittings leading from branch to branch. Apply glue

to both ends of the pipe and to the inside of the hub then twist pipe into hub until

firmly seated. Glue will set instantly.

Fasten low-voltage wire to pipe run with cable ties

approximately every 6' and at each Ell. This will pre-

vent drooping, possible damage to wire insulation or

ripping. Electrical tape may be used if double-wrapped

around wire and pipe. For the proper way of splicing,

refer to the section on wiring.

The finished installation in the illustration shows an air

vent obstructing an intended branch line (illustration

4, dotted line).

A 45° wye can be advantageously utilized to by-pass this and similar obstructions by

installing the wye into the main line further downstream.

The use of a 45° wye will save you the additional installation time of two extra fittings.

The 180° "loop" shown is further explained in illustration 11.

From basement up

Simply reverse the procedure of the branch line installation, as your main run will

be located below instead of above the inlet valves. When the main run is installed

between, or on the underside of the floor joists, the risers and drops can be concealed

in a variety of ways.
