INSTALLATION GUIDE

IN GROUND TRAMPOLINE INSTALLATION

Sunbounce trampolines are built to last. Made of best quality European materials and as a result of skilled craftmanship, your trampoline will serve you for years to come.

Safety comes first! In order to achieve the best trampolining experience that will keep you fit and energised, please read these assembly instructions and safety recommendations thoroughly to minimize any chances of injuries.

SUNBOUNCE TRAMOLINES

Step 1: Assembling the frame

Lay the frame sections (Part A) into a circlewith the spring holes facing upwards. Push all sections together until all are fully mated together.

Note: On the long sides, the frame will appear to bow outwards – this is by design. When the springs are attached the frame will pull inwards, but always have a slide outward bow.

Important note: all trampoline sizes are approximate and can be up to +/- 3” (2.5 cm) different to those that
we publish.

Step 2: Fitting the mat and installing the springs

Lay the mat flat inside the frame. Make sure the logo is facing upwards. In order to make the installation of the
jumping mat easier, locate the four rings in the 12, 3, 6 and 9 o’clock position directly opposite each other and attach four springs on these locations first. Then continue by attaching springs to every eighth ring, followed by every fourth and so on until all springs are attached.

At first, it may look like the mat won’t fit, it will however stretch to the correct size when you finish attaching all springs.

Important: Be sure all spring hooks are well attached to the frame.

Step 3: Attaching the PVC retaining panels

The next step is screwing the PVC retaining wall panels to the frame. You will need the cross-head screwdriver and gloves. Take one panel and place it against the outside of the frame. You will find four holes in the frame and four holes in the wall panel. Insert and tighten the four screws to attach the panel tightly to the frame. Repeat with all remaining panels.

Step 4: Digging the trampoline pit (part 1)

Position the frame on the location you chose and mark the position on the ground. It’s best to mark out a hole a bit wider than the diameter of your trampoline.

This will make it easier for you to put the frame in and find the right level. Dig the pit to the following dimensions:

TRAMPOLINE SIZE

DIMENSION A – OUTER HOLE	DIMENSION B – INNER HOLE	DIMENSION C – TOTAL DEPTH
10 ft / cca. 305 cm	8’8’’	2’6’’
12 ft / cca. 366 cm	10’8’’	2’11’’
14 ft / cca. 427 cm	12’8’’	2’11’’

The hole should not accumulate water (in which case the drainage is necessary) and it should be possible to clean during maintenance.

First, dig the outer hole to create a ledge for your trampoline frame, which needs to be 10″ deep. This is the exact frame height, so that the safety pad on top of the frame will be just above the grass level. Continue by digging the inner hole.

Dig the inner hole according to the dimensions of your trampoline and with a bowl-shaped bottom. The inner hole should be 1’4″ narrower than the trampoline size. This will leave a 8″ ledge all around on which the trampoline will sit.

HINT:
It’s a relatively easy task to hand dig the hole for smaller size trampolines, but it would be best to hire a mini digger to excavate most of the soil and leave you with the finishing touches.

Note: You will need to save some of the soil for later.

Step 5: Digging the trampoline pit (part 2)

Cover the complete surface with the weed protection, then place the trampoline frame into position. Make sure the membrane ‘hugs’ the shape of the hole and sits right at the bottom of the hole – keeping jumping space under the mat.

Step 6: Placing the trampoline into the pit (part 1)

Carefully place the trampoline on the ledge covered with the weed protection. Fill the remaining free space around the trampoline with the remaining soil, then cut off the excess material of the weed protection.

Check that the trampoline is well levelled. You may want to remove the trampoline to make any adjustments to the height that the frame is sitting on. Aim for the trampoline jumping mat to sit flush to the ground.

Step 7: Placing the trampoline into the pit (part 2)

There should be no gap between ground and your trampoline.

Finally, re-lay the saved soil around the trampoline and compact down as much as possible.

Step 8: Attaching the frame pad (part 1)

Lay the safety pad on top of the trampoline, aligning the pad section joints with the joints of the frame and the eyelets facing up. Insert the elastic toggles through the eyelets so the loop end of the elastic faces outwards and the toggle end is on the inside.

Step 9: Attaching the frame pad (part 2)

Flip the frame pad over and pull the elastic band around the frame. Insert the toggle into the loop, then rotate the toggle inwards to secure it. Repeat with all frame pad elastics.

The frame pad must cover the entire frame and all springs.

HINT:
If you find it too difficult to get the toggles in place, wedge a screwdriver carefully between the frame and PVC panel to attach the toggle. Using a flat-head screwdriver (or similar), push the loop end between the wall panel and frame. Insert the toggle from underneath and rotate to secure. Repeat with all elastics.

Step 10: Attaching the frame pad (part 3)

The last step to secure the frame pad to the trampoline is placing springs into the “spring loops”. You will find them on the underside of the frame pad where each pad section joins the next one. Remove a single spring under every loop, slip it through the loop and reattach to the frame. Repeat with all loops. This will prevent the front of the pads from lifting up.
