How to replace the UNICUM dry-pit motor on your Abriblue pool cover

If you own an ⟨1⟩Abriblue⟨/1⟩ pool cover equipped with a dry-pit motor and it is showing signs of wear, this practical guide explains how to ⟨2⟩replace it easily and safely⟨/2⟩.
We will detail the steps, necessary equipment, and the appropriate references so that your cover regains optimal functionality.

Which dry-pit motor should you use for your Abriblue cover?

The choice of motor depends on the size and weight of your submerged cover:

  • ⟨1⟩⟨2⟩UNICUM DL6010 (500 Nm)⟨/2⟩⟨/1⟩: recommended for small to medium-sized Abriblue covers.

  • ⟨1⟩⟨2⟩UNICUM DL7710 (900 Nm)⟨/2⟩⟨/1⟩: recommended for wider or heavier Abriblue covers.

For power and control, use the ⟨1⟩UNIBOX 450 control box⟨/1⟩, specifically designed for UNICUM dry-pit motorizations.
This box manages the 24V power supply and allows you to control the cover via ⟨2⟩remote control⟨/2⟩ or ⟨3⟩wall-mounted switch⟨/3⟩.

These motorizations are fully ⟨1⟩compatible with Abriblue systems⟨/1⟩ such as the ⟨2⟩IMM’Box⟨/2⟩, ⟨3⟩IMM’Ax⟨/3⟩ or ⟨4⟩Open Neo⟨/4⟩ ranges, which use dry pits to protect the motor out of the water.

Why replace a dry-pit motor?

The dry-pit motor ensures the ⟨1⟩automatic opening and closing⟨/1⟩ of the cover while being ⟨2⟩isolated from water⟨/2⟩ in a watertight pit or technical compartment.
Over time, it may show certain signs of failure:

  • Partial or total blockage of the cover during winding or unwinding.

  • Unusual noises, vibrations, or jerks upon starting.

  • Erratic response or no movement when commanded.

  • Poor adjustment or drifting of the ⟨1⟩limit switches⟨/1⟩ (the cover no longer stops correctly).

Replacing the motor allows you to:

  • ⟨1⟩Preserve safety⟨/1⟩ and reliability of the cover.

  • ⟨1⟩Avoid premature wear⟨/1⟩ of the winding shaft and fixings.

  • ⟨1⟩Restore smooth and silent operation⟨/1⟩, compliant with original Abriblue performance.

Equipment and tools needed for replacing your dry-pit motor

Before starting, make sure you have:

  • ⟨1⟩⟨2⟩UNICUM DL6010 (500 Nm) or DL7710 (900 Nm) motor⟨/2⟩⟨/1⟩ depending on your cover.

  • ⟨1⟩⟨2⟩UNIBOX 450 box⟨/2⟩ for the power supply.⟨/1⟩

  • Allen key, flat-head and Phillips screwdrivers.

  • Set of wrenches.

  • Spirit level for shaft alignment.

  • Protective gloves and goggles.

  • Abriblue documentation for wiring diagrams and limit switch settings.

Step 1: Secure the pool and cut the electricity

  1. Turn off the ⟨1⟩main power supply⟨/1⟩ at the panel and the cover's control box.

  2. Ensure that the cover is ⟨1⟩completely closed⟨/1⟩.

  3. Protect the area around the pool to avoid any accidents.

Step 2: Access the dry-pit motor

  • Open the dry-pit cover provided for this purpose on the Fluidra pool cover.

  • Check that there is ⟨1⟩no standing water⟨/1⟩, debris, or corrosion — the motor must be in a "dry pit" above the water level, as recommended by Fluidra. ⟨2⟩⟨3⟩⟨4⟩⟨5⟩⟨6⟩Fluidra Industry⟨/6⟩⟨7⟩+1⟨/7⟩⟨/5⟩⟨/4⟩⟨/3⟩⟨/2⟩

  • Locate all fixings holding the motor to the cover's shaft as well as the wiring (24V power, limit switches, control link).

  • ⟨1⟩Tip⟨/1⟩: Before disconnecting anything, take a clear photo of the wiring and the position of the components to guide reassembly.

Step 3: Disconnect and remove the motor

  1. Carefully disconnect all cables: power supply, limit switches, connection to the roller.

  2. Remove the fixings that hold the motor on the shaft.

  3. Remove the motor and inspect:

    • The shaft to ensure it is not bent.

    • The bearings to ensure they rotate freely.

    • The coupling for cracks or excessive play.

Step 4: Install the new replacement motor for your pool cover

  • Position the new motor ⟨1⟩in perfect alignment⟨/1⟩ with the winding shaft in the dry pit.

  • Secure it firmly with the screws and supports provided.

  • Reconnect all cables according to your photos (power supply, limit switches, control link).

  • Install the ⟨1⟩control box⟨/1⟩ and connect it correctly to the motor.

  • Set the high and low limit switches to ensure smooth movement of the cover.

  • Check that the shaft and motor are properly aligned: any misalignment can cause blockages or premature wear.

Step 5: Tests and checks of the UNICUM DL6010 / DL7710 motor for dry pit

  • Restore the power and perform several opening and closing cycles of the cover.

  • Verify that the cover moves up and down ⟨1⟩smoothly⟨/1⟩, without noise or blockage.

  • Ensure that the pit remains ⟨1⟩dry⟨/1⟩ and watertight, without water infiltration.

  • Check the proper functioning of the limit switches and the remote control.

 

Step 6: Maintenance after replacement

To extend the life of the motor:

  • Regularly clean the dry pit to prevent accumulation of leaves or debris.

  • Check the motor and control box annually.

  • Keep a record of interventions and photos for tracking and maintenance.

  • Follow the manufacturer's instructions for maintenance and winterizing to extend the life of the motor and the cover.

Replacing the dry-pit motor of your Abriblue cover with an ⟨1⟩⟨2⟩UNICUM DL6010 or DL7710⟨/2⟩⟨/1⟩ and the ⟨3⟩⟨4⟩UNIBOX 450⟨/4⟩⟨/3⟩ box is simple.

If you follow the steps described: securing, dismantling, installation, adjustment, and checks.

With regular maintenance, your Abriblue cover will regain smooth and reliable use, allowing you to fully enjoy your pool in complete safety.

FAQ 

⟨1⟩Q: Can I install a generic motor instead of a UNICUM motor on an Abriblue cover?⟨/1⟩
⟨2⟩A:⟨/2⟩ It is preferable to use a compatible ⟨3⟩UNICUM DL6010 or DL7710⟨/3⟩ motor. These models respect the mechanical and electrical specifications of ⟨4⟩Abriblue⟨/4⟩ covers, guaranteeing adapted torque and perfect integration with the ⟨5⟩UNIBOX 450⟨/5⟩ box.

⟨1⟩Q: Where should the UNIBOX 450 box be installed?⟨/1⟩
⟨2⟩A:⟨/2⟩ The box must be placed in a ⟨3⟩dry and ventilated⟨/3⟩ technical room, more than ⟨4⟩3.5 m from the pool⟨/4⟩ in accordance with electrical standards. It must remain accessible for limit switch adjustments and maintenance operations.

⟨1⟩Q: Can I replace the motor myself?⟨/1⟩
⟨2⟩A:⟨/2⟩ Yes, if you have basic knowledge of electricity and mechanics. However, it is advisable to ⟨3⟩call on a certified Abriblue installer⟨/3⟩ to guarantee the watertightness of the dry pit and the electrical conformity of the installation.

⟨1⟩Q: How do I maintain my Abriblue dry-pit motor?⟨/1⟩
⟨2⟩A:⟨/2⟩ Regularly clean the pit or dry box to prevent the accumulation of water and debris. Check annually:

  • the ⟨1⟩functioning of the limit switches⟨/1⟩,

  • the ⟨1⟩tightness of the shaft fixings⟨/1⟩,

  • the ⟨1⟩watertightness of the seals⟨/1⟩ around the motor.
    Regular maintenance extends the motor's life and ensures optimal operation.
