perforation
Check the site according to the installation drawings, mark the positions of the holes to be opened, and open the holes first.
Opening is to pay attention to on-site protection, especially when using rhinestones, appropriate protective measures should be taken to minimize the contamination of the wall.
The method of protection is to use a paper shell of the right size on the top of the opening to prevent upward splashing, and use another plastic sheet long enough to determine the upper edge of the plastic sheet with scotch tape to determine the lower edge of the opening. The plastic sheet can collect the mud water of the rhinaute work, and prepare a plastic bucket on the ground to accept the mud water, such protective measures will not pollute the wallpaper even if the wall is pasted.
The opening of the external wall must have a slope to ensure that the slope of the air pipe is outdoor when installing it to prevent the rainwater from flowing back.
1) Wall drilling and installation methods
1. Use a water drill to drill holes, and the opening holes of the wall are tilted 2 degrees to the outside
2. Bury the PVC pipe and fill the seal. Polyurethane foam is used as filler between the air pipe and the hole shelter.
3. Install the tube cover and seal the tube cover with waterproof sealant.
2) Installation method of wall embedded holes
1. Metal casing is embedded in the wall, and the embedded component is tilted 2 degrees to the outside
2. Embedded PVC sleeve, polyurethane foam is used as filler between PVC pipe and hole wall.
3. External wall insulation treatment.
4. Install the pipe cover, and seal the pipe cover with water sealing paste.
After the opening is completed, it is necessary to do sanitary cleaning, and keep the site clean to facilitate the installation project.
Install the fresh air engine
The following describes the installation of the common ceiling type domestic heat recovery ventilation fan
1) Determine the installation position of the new fan
According to the drawings, determine the position of the air supply outlet and the exhaust outlet. The section of the new fan with the thermal insulation layer should face outdoors.
Determine the position of the overhaul port, and ensure that there is enough maintenance space for the overhaul port.
2) Ceiling new fan
Before hoisting, it is first necessary to fix the lead screw used for hoisting, and then start hoisting.
Hoisting installation should pay attention to leave a gap of not less than 1 cm between the new fan and the ceiling or use a flexible rubber shock block to prevent the heat recovery ventilation fan from causing the whole building and noise. After hoisting the new fan, check the new fan to ensure that the installation is stable and smooth.
