Relax in the Shower for a few minutes.

Lock the valve by rotating the valve cap clockwise.

Push the black pip into the closed position with your finger, remove the comfort insert (to prevent trapped air) then invert the Hydropump under the shower head until full of water.

Replace the comfort insert.

Place the Hydropump over your flaccid penis tight up to your pelvic seat with the black pip in the closed position. The chamfer can be positioned facing either upwards or downwards depending on your level of comfort.

Make a seal against your body, ensuring that the positioning is comfortable and that your testicles are well clear.

With the Hydropump angled slightly upwards, open the valve by pushing the black pip to the central position and commence pumping.

Ensure that the black pip is in the central (open) position when pumping.

Pump slowly and evenly until the bellows remain depressed, indicating that optimal vacuum has been achieved.

To increase the vacuum further and for more control, use the hand ball pump either with the hose or connected direct to the pump. Please note, the fit between the handball pump and the Hydropump valve is designed to be a non permanent connection. For this reason the handball should be held in position whilst in use, and removed when optimum vacuum is achieved. If a more permanent connection is desired, please use the hose connector.

Ensure you follow the recommended instructions.

To remove the Hydropump, unlock the valve by rotating the valve cap anti-clockwise and release the vacuum by depressing the valve cap inwards to activate the quick-release mechanism and slide the Hydropump off your penis.
