PCircle Diffuser Installation

Step 1: Preparation

1. Identify all included parts and ensure nothing is missing.
   
2. Prepare the installation site in the ceiling, ensuring enough space for the unit.
   

Step 2: Cable Connection

1. Attach the cable (c) to the back plate using screw a.
   
2. Secure the other side of the cable to the main unit using screws b.
   

Step 3: Mounting the Unit

1. Position the back plate on the ceiling opening.
   
2. Insert the connected cable and raise the plate into position.
   
3. Secure the plate by tightening screws b into the main unit.
   

Step 4: Fixing the Mounting Clips

1. Attach the mounting clips (d) on the sides of the unit by pressing them into place.
   
2. Once all clips are in position, secure them with screws e.
   

Step 5: Installing into Ceiling

1. Place the unit into the prepared ceiling opening.
   
2. The clips (d) will hold the unit firmly in place.
   
3. For double plasterboard ceilings, use the extended clip setting as shown in the diagram (“When two layers of plaster”).
