installation steps

1. Selection of installation location

■ Should be installed on the inner wall close to the outdoors

■ The installation wall must be flat, and the drilling position should avoid the embedded pipeline of the building

2. Place the wall mounting plate

■ Use a spirit level to place the mounting plate horizontally on the wall

■ Mark the hole with a marker (4 inverted convex holes; 4 small round holes; 2 large round holes)

3. Hole on the wall (110mm in diameter)

■ Please wear protective clothing before work (wear goggles, gloves and masks)

■ Make holes according to the mark

■ When opening the air duct hole, the puncher tilts down 2°-5° (outdoor low, indoor high) until it penetrates

■ In the process of drilling holes, the drill must be withdrawn frequently to remove the wall material, and auxiliary tools such as hammers and chisels can be used accordingly

4. Drill expansion plug holes and body suspension holes

■ Punch holes according to the hole positions determined on the wall mounting plate

■ Drill diameter: 8mm

■ Minimum depth: 4 small round holes: 80mm, 4 inverted convex row holes within 4mm of the outline, wall sinking: 5mm

■ Put expansion screws into 4 round holes

5. Round pipe installation

■ Fix the outdoor rain cover and the air pipe tightly with a pipe clamp or a cable tie

■ Put the round pipe into the wall hole from the outdoor side, pull it in from the room, and connect it to the 80# vent of the equipment, and make sure that the vent of the weather cover is downward

■ Waterproof between the outdoor rain cover and the wall (filled with glass glue or structural glue)
