1. Introduction
Thank you for choosing our product Poollift Delphin. The Poollift serves as a valuable support for
entering and exiting a swimming pool. It enables disabled persons or wheelchair users to refresh
themselves or e.g. to perform medicative water aerobics.
Your Poollift has been developed and constructed by experienced professionals and therefore its
functionalty is ensured.
Please read this manual carefully before using the Poollift.
2. Technical Specifications
Description
The Poollift Delphin is powered by water pressure.
The required water pressure at a load of 85 kg is 0,3 Mpa. For a maximum load of 120 kg it is
necessary to have a water pressure of min. 0,4 MPa. In most homes the water pump provides the
necessary amount of 0,4 MPa.
The fastening of the Poollift is suitable for different types of swimming pools.
The Poollift is deliverd with a recessed or a screwed panel. Both options can be accomplished with a
extended C-tube, if the distance between the edge of the pool and the fastening point of the panel is
wider than 350 mm.
The seat rotates automatically 90° to the entry and the exit point.
The operating lever on the entry level as well as on the exit level (in the water) ensures that the
access and the exit is possible without any further help by another person
Used materials
•Stainless steel AISI 316L V4A (cylinder, tube, pillars, sockets, outlet)
•Polypropylen (seat)
•Rubber (seat)

3. Installation Instructions
Fastening possibilities
Recessed panel
A drill-hole with a diameter of at least 120 mm and a depth of 160 mm has to be executed. Concrete
or a appropriate glue ought to be used for the fastening. Ensure that the panel is fixed vertically and
that the upper edge is on one level with the floor before gluing.
If the Poollift has to be dismantled before winter (e.g. outdoor installation), it is possible to blind the
hole in the floor with a screw cap.
Screwed panel
Six small drill-holes have to be executed for that kind of panel. Heavy duty anchors or dowels should
be used for the fastening.
If the Poollift has to be dismanteld, it is possible to simply unscrew the panel.
Setting up
A minimum water depth of 1050 mm is necessary. Furthermore it is important to ensure, that the
entry point is easily accessible for users and that also a water supply has to be possible.
When using a standard C-tube, the center of the panel should be at least 130 mm to max. 350 mm
away from the edge of the pool. If the distance of 350 mm is exceeded it is possible to use an
extended C-tube (special order).
Installation
Recessed panel:
Execution of a core hole (diameter at least 120 mm) and
then gluing the sleeve (see picture)
Screwed Konsole:
Screwing the panel with 6 screws on the floor
safety ring
Measuring out the place where the panel will be

together
Inserting the safety ring (see first
picture) into the panel

4. Start-up Operation
1. After installing the Poollift please check if all screw connections are tightened.
2. Open the water supply line to let the air escape from the pressure water hose. Then shut the
water supply again.
3. Move the operating lever upwards and push the cylinder downwards to let the air escape from
the cylinder.
4. Connect the pressure water hose to the valve. Always use drinking water for the operation
and never water from the pool!
5. Adjust the entry height according to the customer’s request.
Locking (lock)
The Poollift can be bolted and locked if it is in the upper landing. That way it is protected against
unauthorized use.
ATTENTION!
The Poollift must be unlocked before it can be moved!
Carriage
There are transport wheels optionally at one’s disposal.

Poollift Delphin page 9
5. Operating
The operating lever on the entry level as well as on the exit level (in the
water) ensures that the access and the exit is possible without any further help
by another person.
The movement direction is controlled by the 3-way-valve. To go upwards you
have to pull the operating lever down and if you want to go downwards you
have pull the operating lever up. Particular parts are shown in the attachment
„Mechanical scheme“.
6. Diagnostics
Poollift holders can check their installation for flaws on their own accord with the help of the
following points. Apart from that they can contact the service company if malfunctions occur.
By no means it is allowed to manipulate, change or remove any components of the installation.
The Poollift does not move (or too slow) upwards?
Check:
•The pressure water supply must be opened and the pressure water hose must be flawless
•The valve must be in the end position (turned down)
•Appropriate water pressure is necessary.
•There must not be any defect on the seal of the cylinder
The Poollift does not move (or too slow) downwards?
Check:
•The drain hose must be in good condition.
•The valve must be in the end position (turned up)
•There must not be any defect on the seal of the cylinder
7. Cleansing and Maintenance
The Poollift is very easy to clean. The installation has to be cleaned from eventual organic and
inorganic sediments regularly. Appropriate care ensures a problem-free operation over the long term.
Please check all screw connections regularly and tighten loose screws.
The Poollift uses drinking water as a lubricant, that is why it is not necessary to lubricate the
installation.

Poollift Delphin page 10
If the Poollift is out of service for extended periods of time (e.g. in winter), it is recommended to
damp the seal of the cylinder before it is commissioned again.
Don’t keep the Poollift outside during winter, because remaining water in the cylinder could damage
the installation. Seperate the pressure water hose from the Poollifte after dismantling and turn the
operating lever in the upper position.
Afterwards push the cylinder in the upper and the lower position until the whole amount of the water
inside the cylinder has leaked out. After draining the cylinder keep the cylinder in the upper position.
If necessary close the Poollift in that position using the lock.
It is absolutely required to maintain your Poollift regularly.
How to replace the seals and pistons is described in the the document „Instructions for seal- and
piston-replacement“.
8. Packaging, Delivery and Storage
In some cases the Poollift will be deliverd disassembled in two wooden boxes.
The assemblage is carried out on the spot.
Please protect the Poollift from falling down, overturning and intense vibrations during the transport.
Store the Poollift in a dry, clean and dust-free interior at temperatures between 5° and 40°C and a
humidity of max. 80%.
The Poollift must not be exposed to the effects of chemicals!
