4.2.1 Mounting the Sunny Island on a Stone Wall
1. Place the wall mounting bracket against a suitable wall for mounting and align using a level.
Mark the position of the drill holes using the wall mounting bracket. When doing this, use at
least one hole on the left side and one hole on the right side of the wall mounting bracket.
2. Check the mounting location for current-carrying lines. If there are current-carrying lines at the
mounting location, select a different mounting location.
3. Drill holes on the markings for them.
4. Secure the wall mounting bracket to the wall using
appropriate screws and washers. Tighten the
screws in a clockwise direction.
Risk of injury due to the Sunny Island falling. Physical injury (fractures or crushing) and damage to
the Sunny Island.
•Ensure that the wall can carry the weight of the Sunny Island.
• If mounting onto a wooden wall with studs, ensure that the wall mounting bracket is firmly
connected with all studs.
Risk of injury due to the Sunny Island falling during transport or mounting. Physical injury
(fractures or crushing) and damage to the Sunny Island.
• Consider the weight of the Sunny Island which is 139 lb. (63 kg).
• Use the recessed grips or steel bars for transporting and mounting.
