Gasket Installation
•Most of the gasket material has been installed at the factory, however additional gasket has been
provided in case any gasket has fallen off during shipping. If gasket installation is required, follow
the instructions below. The gasket on the face of the ladder is not installed in the factory, but
detailed instructions are provided in step 8 on page 10.
•Apply gasket (PN 8-532) in the required locations as shown in the figures below.
•Place gasket along the section to determine the length needed.
•Cut gasket to appropriate length, within the width of the runway only, do not include the shoulder.
•Remove backing and adhere gasket to slide.
•All gaskets below are applied as shown in the gasket section detail (see step 8 for further details
on installing the ladder gasket, PN 8-531)
FIGURE B
NOTE:
BE SURE TO APPLY ANTI-SEIZE TO ALL
FASTENERS TO PREVENT GALLING.
NOTE: Use pistol-grip clamps as
necessary to align the molded parts.

HELIX2 Assembly
Before getting started:
•To prevent damage to the parts during assembly, it is recommended that cardboard or some
other protective barrier is laid down on the ground where the slide is to be assembled.
•Verify that the gasket material is affixed to the slide parts as shown on page 7
•During assembly, be sure to apply a thin coat of anti-seize compound to the threads of all
fasteners. Anti-seize helps aid in assembly, prevents galling, and improves corrosion resistance.
1. Attach the pedestal part to the runway exit section as shown in FIGURE C by inserting the two lag
screws into the holes located in the bottom of the pedestal.
2. Before inserting the lag bolts into the side of the runway exit part, 1/4” (6 mm) pilot holes must be
drilled into the center of each of the recesses, each location is marked with a dimple showing where
to drill. The pilot holes should be drilled through both the runway exit section and into the pedestal.
FIGURE C
3. Place the assembled runway exit section and pedestal upright so that the pedestal is resting on the
ground. Notes: It may take more than one person to perform this step. Verify that the gasket
material is properly attached before assembling the parts.
4. Insert the threaded studs into each of the threaded inserts as shown in FIGURE D. The studs should
be screwed in by hand until they reach the bottom of the insert. If the studs cannot be threaded in by
hand, pliers may be used. Before using pliers, a piece of cloth should be placed over the stud to
protect the threads from damage. Note: Be sure to apply anti-seize to all fasteners to prevent
galling.

5. Assemble the top ladder section and lower ladder section as shown in FIGURE E. Insert the two
button head cap screws into the threaded inserts as shown in FIGURE E. Do not fully tighten the
screws at this point; start the screws into the threaded inserts. Note: Be sure to apply anti-
seize to all fasteners to prevent galling.
6. Insert the button head cap screws into the back side of the ladder as shown in FIGURE F. Tighten
the screws until snug. Go back and fully tighten the screws from Step 5. Note: Be sure to apply
anti-seize to all fasteners to prevent galling.
7. Insert the two carriage bolts into the steps as shown in FIGURE E. Tighten the nuts onto the
carriage bolt until the lock washer is fully compressed. Note: Be sure to apply anti-seize to all
fasteners to prevent galling

8. Before applying the gasket to the top of the ladder, be sure that the joint surfaces of the top runway
and ladder sections are clean and dry. Unroll the gasket material and hold so that length of the gasket
is centered on the center of the ladder joint. With the exposed adhesive side of the gasket facing the
ladder joint surface, apply the gasket starting at the center of the part, working outward to the sides.
Be sure that the bottom edge of the gasket material is held against the shelf on the ladder part during
installation, see reference images below. Do not make too tight of a bend radius with the gasket when
transitioning the gasket up the vertical edges of the joint. The transition radius should be as large as
possible. Making too tight of a bend radius will cause the gasket to kink and possibly leak. The
gasket should be centered on the available space in the vertical area of the joint, see reference
images below. Once the gasket is in place, firmly press down on the gasket in all locations to ensure
that the gasket has completely adhered to the ladder joint surface. Remove the paper backing on the
outward face of the gasket to expose the adhesive. Use caution not to remove the adhesive strip
from the gasket when removing the paper backing.

9. Lay the ladder assembly on the ground with the steps facing down as shown in FIGURE G. Lift the
upper runway section and align the threaded studs sticking out of the top ladder section with the
holes in the upper runway section. Attach the runway to the ladder using the hardware shown in
FIGURE G. Tighten until the lock washer is fully compressed.
Notes: It may take more than one person to perform this step. Verify that the gasket material
is properly attached before assembling the parts. Be sure to apply anti-seize to all fasteners
to prevent galling.
10. Apply a .25 inch (6 mm) bead of Silicone sealant (Silicone II or similar) around the base of the cone of
the slide’s center column. See FIGURE H.

button head cap screw as shown in FIGURE I through the slides center column. Do not tighten the
bolt at this point. Notes: It may take more than one person to perform this step. Be sure to
apply anti-seize to all fasteners to prevent galling.
12. Finish assembling the two runway sections using the hardware shown in FIGURE J. Note: Be sure
to apply anti-seize to all fasteners to prevent galling.
a. First, the 2” Hex Head Tap Bolt (Item 13) should started into the threaded insert; do not

ON-DECK MOUNTING INSTRUCTIONS
1. Place the assembled slide on the deck relative to the pool wall. Ensure that the exit flume clears
any coping. Slide may be angled slightly providing all dimensions are maintained as noted in the
Manufacturer’s Placement Instructions noted in the following section.
2. With the slide in its proper location, center punch or otherwise mark through
the (8) mounting holes at the bottom of the ladder and pedestal so that a
visible mark is apparent on the concrete.
3. Move the assembled slide aside to facilitate drilling of the anchoring holes.
4. Using a power drill and a 1/2” (13 mm) concrete drill bit, drill the holes to a
depth of 4” (0.102 M). Use tape or a marking on the drill bit to ensure that the
hole for the anchor is drilled to the required depth. Maintain drill hole straight
and perpendicular for proper holding strength of anchor stud.
5. Clear the holes of all debris. Assemble anchor with nut and washer so that the
top of the nut is flush with the top of the anchor. Move the slide over the
holes before inserting the anchors. Drive anchor through the slide
mounting holes so that nut and washer are flush with the surface material.
6. Expand anchor by tightening nut 3 to 5 turns. Once anchor is set remove nut
and install a lock washer, item # (3), and retighten nut to a torque of 25 ft.-lbs
(33.9 N-m).

SLIDE PLUMBING INSTRUCTIONS
1. The HELIX2™is designed for a water supply line of 1” pipe.
Plumb from pool return line with a 1” PVC pipe “stubbed up” at the
deck positioned at the base of the ladder. Refer to FIGURE A on
page 5. FIGURE A is for reference only. Assembled slide should
be placed in its correct location and the “stub up” location marked
and installed before mounting the slide to the deck. “Stub up”
should be dark grey PVC to match the plumbing assembly of the
slide. Note: “Stub up” should extend above the deck 18” (457
mm) in height; it will be cut down later in the installation
process.
2. If a garden hose is to be used, a garden hose adapter fitting is
included with the slide. Assemble the pieces as shown in FIGURE
M and attach to the end of the PVC plumbing assembly at the
base of the ladder.
3. Proceed to the following section for ON-DECK MOUNTING. After
the slide has been mounted to the deck, attach the “stub up” to the
plumbing assembly installed in the ladder.
4. The HELIX2™can handle up to 20 gallons per minute (75 L/min). Water flow to the main water
supply is to be regulated using the ball valve (16) near the center of the ladder. The fountain feature
can be regulated via the small ball valve just under the top of the ladder. FIGURE L shows the
location of the small ball valve.
5. The fountain feature and the main water supply can be either used together or alone.
a. To use only the main water supply, shut off the small ball valve. Adjust the large ball valve for
the desired water flow.
b. To use only the fountain, shut off the large ball valve. Adjust the small ball valve for desired flow.
6. To use both the fountain and the main water supply together, the large ball valve must be partially
closed. In general, closing the large ball valve more will increase the flow to the fountain. Adjust
the small and large ball valves to obtain the desired flow from each water feature.
