PULSE ShowerSpas 1015 Makena - Manual (Page 2)

Retrofitting An Existing Shower:
Note: In a re-model in which you are not replacing the finished wall surface (tile, or backing
material) it is advisable to purchase a PULSE Showerspa model that covers the location of
the existing valve assembly- either single handle or two-handle type. If your PULSE
Showerspa model does not cover this area, you will need to either choose another PULSE
Showerspa model that does or make the necessary repairs with appropriate materials (i.e.
wallboard, tile, fiberglass, etc.).
1. Turn off the water supply to the shower. (Note: Typically there is a gate valve where
the water main enters the house. Turning the water valve off at the hot water tank does
not turn off the cold water supply line.)
2. Make certain the water is completely turned off to both hot & cold supply lines of the
Shower. (Turn the shower valve on, both hot and cold, to verify the water supply is off.)
Open a sink faucet in the bathroom in which you are installing the Showerspa to relieve
any pressure and help to adequately drain the shower supply lines.
3. Remove the handle(s) and trim cover(s) of your existing valve exposing the valve body in
the wall.
4. Locate the hot and cold supply lines entering the valve. Using a reciprocating saw with
sharp metal saw blade, cut the existing valve out, preserving the threads of the supply
lines entering the valve. (Note: you should also cut the riser within the wall supplying the
existing shower head.) Carefully twist and remove the valve.
5. Unscrew the old shower head from the arm and then unscrew the arm.
6. It is recommended to extend the water supply lines outside the wall cavity parallel to the
finished wall surface. Attach a male threaded fitting to each supply line, maintaining ¼”-
½” space between the male threaded fittings and the finished wall. The open end of the
male fitting should point down. For your convenience we have included (2) ½” 90°
fittings
3 .
7. Make certain the location (height/width) of the stub-outs and connecting to them does not
interfere with the desired mounting height of the Showerspa.
8. Mark the location of the holes for the mounting bracket making sure the bracket is level.
For a person 5’8” – 6’2” tall, we recommend 64” from finished floor height 4 . To locate
bottom mounting bracket, measure the distance between top and bottom mounting slots
in the Showerspa. Use this measurement to position bottom bracket making sure bottom
bracket is plumb with the upper bracket. Before drilling holes for the brackets, make
certain the Showerspa will rest flat against finished wall surface at the desired mounting
height with the supply lines connected.
9. Drill ¼” holes through the wall surface using a masonry bit. Drill slowly through wall
surface to avoid cracking and chipping. Insert anchors and securely screw brackets to
wall. Before connecting the hot and cold supply lines, mount the Showerspa on the wall,
checking the height, and making sure the Showerspa feels secure.
10. Connect hot and cold water supply lines to male threaded pipe, do not over-tighten.
Before you mount the Showerspa, check the fittings to make sure they are secure. Turn
on water and check for leaks. When fittings are leak-free mount Showerspa on wall.
11. Seal around the body of Showerspa with a bead of silicone.
3 Additional fittings may be necessary depending on your specific situation.
4 This height can vary depending on several factors (i.e. location of supply lines, old valve access area,
personal preference, etc.).
