FLEXIN F0920272 Retractable Hose System
Product Information
The retractable hose system is a versatile and convenient solution for central vacuuming. It allows for easy access to vacuum power throughout the house without the hassle of carrying a traditional vacuum cleaner.
Features:
- Retractable hose for easy storage
- Choice of central vacuum unit
- Multiple inlet locations
- Durable PVC tubing
- Low voltage cable for power connection
- Easy installation on various surfaces
Specifications:
- Maximum hose length: 12 meters
- Minimum hose length: 5 meters
- Recommended network tubing length: At least 13.5 meters longer than the hose length
Product Usage Instructions
Installation Procedure:
- Determine the desired location for the central vacuum unit and mark the position for inlet locations.
- Choose a suitable central vacuum unit based on your requirements.
- Position the inlet locations strategically throughout the house.
- Determine the path for the network tubing and plan accordingly.
- Follow the specific installation instructions based on the type of surface
- New construction: Attach the inlet to the wall stud and leave enough space behind it. Install PVC tubing and ensure a secure connection.
- Installation on drywall: Use the provided template to create an opening in the wall. Insert the inlet into the wall and fix it to the drywall. Connect the network tubing and make the electrical connection. Fill the back of the inlet with plaster to level it with the wall surface.
- Installation on wall and plaster: Install the inlet into the wall and directly fix it to the plaster. Connect the network tubing and make the electrical connection. Fill the back of the inlet with plaster to level it with the surface.
- During the installation of the network tubing, ensure that the tubes are not crushed, which could affect the movement of the retractable hose.
- Use specific fittings designed for the retractable hose system to create a smooth and secure path for the hose.
- Ensure that the network tubing allows for a single-level placement of the hose, avoiding installation on multiple levels.
For detailed installation instructions and safety precautions, please refer to the complete user manual.
Retractable Hose System Installation Guide
WARNING
This manual assumes that the installer has working knowledge and experience
installing traditional central vacuum systems.
It is critical that only parts designed for the Sistem Air retractable hose
system be used in the installation. Sistem Air parts include screws, seals,
washers, hoses, sweep 90’s, 45’s, etc. Failure to use these parts will void
any warranty offered by the manufacturer.
Installers are responsible for adhering to all local building codes.
Plan the installation
Planning is the key of a successful installation of a central vacuum system. A
balance between the best locations for the inlet valves and the practicality
of installing in these locations is essential. With a little ingenuity, most
locations can be reached.
Hose lengths
Let customers know that you will custom the hose size to fit each floor. Hose
kits come in 9 m, 12 m or 15 m lengths.
Power Unit Selection
It is important to keep in mind that air flow is reduced with longer hoses. To
compensate for the loss of air flow, a larger power unit is required.
Valve locations
A 50’ (15.2 m) hose will usually cover between 170-220 m2.
Plan pipe runs
Carefully read the “pipe runs” section of this guide. There is also a diagram
of four typical pipe runs.
Rough In
Determine Valve Height
- If the inlet is to be installed in a downward orientation (hose comes out from the bottom), we recommend that the bottom of the inlet be at 40 to 80 cm from the floor, for maximum ease of use.
- In an upward orientation (hose comes out from the top), we recommend that the bottom of the inlet be at 90 to 120 cm from the floor, for maximum convenience.
New construction
Gyproc Installation
-
Attach the frame of the inlet to the stud (2×4) .
Make sure that the inlet is leveled (figure 1) and that you leave 8 cm free behind the inlet.
-
We recommend to add another stud on the other side to secure the inlet in place (figure 2).
-
Install the pipe into the fitting (figure 3). Glue the pipe into the fitting, making sure it seats all the way to the ridge of the pipe fitting. Brick and plaster Installation
-
Use the template provided in this booklet to cut a hole in the brick (figure 4).
-
Insert the back of the inlet into the wall and screw the frame of the inlet directly to the brick (figure 5).
Once the piping network and wires are connected, seal the back of the inlet into the wall by adding plaster all around it. -
Make sure that the thickness of the plaster is flush with the inlet (about 1 cm) all around the inlet (figure 6).
Pipe runs
-
Don’t forget to use a mitre box to cut your PVC pipes at at perfect 90° angle.
We also advise you to use the deburring tool on your PVC pipes to make sure that the inside is exceptionally smooth -
Do not join pipe run until you have enough pipe length to hold the hose. For example, if using a 12 m hose, install at least 13.5 m of pipe before connecting to another pipe run.
-
In order to ensure enough pipe to store the hose, the pipe runs will sometimes need to make a loop before heading back to the power unit.
-
When installing the pipe straps to secure the piping 7 in place, make sure not to squeeze the pipes (figure 7), so as not to alter the movement of the hose inside the piping system.
-
Any burr or excess glue glob can snag and damage the hose sock as it travels through the tubing. To prevent this, make sure to always apply the glue on the male end, not the female (figure 8).
-
Make sure to remove all burrs from the pipe ends that were cut. Carefully inspect the pipe to make sure the inside is smooth and that the pipe is round and undamaged. Only fittings designed for retractable hose systems can be used in the section of pipe that stores the hose (figure 9).
-
The more 90’s used the more force is needed to pull the hose out of the valve.
-
Try not to use more than four 90’s for each valve. Try to avoid back to back elbows (figure10). Try to space them out as much as possible.
-
It is important to design the pipe runs so the hose is stored on one level (figure 11). Avoid storing hose on two different levels (figure 12).

Typical Pipe
Only fittings designed for retractable hose systems (90’s, 45’s and 22.5’s) can be used in the section of pipe that stores the hose.
Runs Diagram
Do not join pipe runs until you have enough pipe length to hold the hose.
For example, if using a 12 m hose install at least 13.5 m of pipe before
connecting to another pipe ru
Low voltage wire
- Run low voltage wire to each inlet just as you would in a standard central vacuum installation.
- Connect the two leads from the switch (on the outside of the valve) to the low voltage wire (figure 13).
- If you are installing this system in Europe, run the low voltage wire through the ITCA-type electric sheath (sold separately), just like any other central vacuum installation and bring the sheath down over the inlet’s wires, into the dedicated opening (figure 14).
- Once the low voltage wires are connected, do a conductivity test before closing wall. We also recommend to perform a suction test to make sure that the installation is sealed properly.
Door Installation
- Once the wall is finished, remove the temporary cover plate (figure 15).
- Simply insert the door into the appropriate slot (figure 16).
- Then, open the door and insert the foor screws in the corners (figure 17) to hold the piece in place. Adjust the 4 screws so that the door closes properly.
