IMPORTANT SAFETY INSTRUCTIONS

READ AND FOLLOW ALL INSTRUCTIONS
Please adhere strictly to the following WARNINGS:

• Position the Caddy and power supply at least 3.5 m (12 ft) from pool’s edge – during operation.

• Take the robotic pool cleaner out of the pool before allowing people to enter the pool.

• When examining the robotic pool cleaner, disconnect the main power supply.

• Ensure that children do not attempt to access the robotic pool cleaner while it is operating.
  Keep the robotic pool cleaner out of the reach of children or persons with reduced physical, sensory or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction. Cleaning and maintenance shall not be done by children.

• Only an original power cord must be used, at all times. If damaged, it must be replaced by a robotic pool cleaner certified technician to avoid hazards.

• To reduce the risk of electric shock replace damaged cord immedietely.

• Do not use an extension cord to connect unit to the outlet; provide a properly located outlet.

• The power supply must be supplied through a residual current device (RCD) having a rated residual operating current not exceeding 30mA.

For USA/Canada installations:
The power supply must be connected only to a supply circuit that is protected by a ground fault circuit interrupter (GFCI). This GFCI should be tested on a routine basis.
To test the GFCI, push the test button. The GFCI should interrupt power. Push the reset button. Power should be restored. If the GFCI fails to operate in this manner, the GFCI is defective.
If the GFCI interrupts power to the power supply without the test button being pushed, a ground current may be flowing, indicating the possibility of an electric shock. Do not use the power supply.
Disconnect the power supply and contact the manufacturer for assistance.

Please ensure that the following PRECAUTIONS are implemented:

• Unplug the power unit before maintaining.
• Operator should keep hands away from driving belt mechanism.
• Only a trained operator should operate the robotic pool cleaner.
• For continued protection against possible electric shock, the power supply unit should be placed at least 11 cm (4 in) above ground.
• When lifting the robotic pool cleaner, take care to prevent back injury.
• Do not bury cord – locate cord to minimize damage from lawn mowers, hedge trimmers and other equipment.
• Do not use the robotic pool cleaner if you have added liquid flocculant or any other clarifier to the pool water. These substances obstruct and damage the robot’s filters.

Removing the robot from the pool

Option A – MyDolphin™ Plus app
The easiest and most fun way to get the robot out of the water:

1. Log into the MyDolphin™ Plus app and click “Pick-up mode”.
2. The robot will reach the wall closest to it and will rise to the water surface.
3. Grab the robot by the handle and pull it out the water.

Use the blue cable to pull the robot as far as the water surface, then use the handle.
Using the cable to pull it above the waterline could damage the connection.

Place the robotic pool cleaner on the edge of the pool and let the water drain out.

CARE AND MAINTENANCE

Make sure the power supply is switched OFF.
Protect the robot

• Rinse the chemicals off the robot when rinsing the filter
• Store in the shade or Caddy cover

We highly recommend rinsing the filter basket and robot after each cleaning cycle. It is far more effective when the filter is clean.
Do not let the filter panels dry out before cleaning. Debris that dries on the filter can be hard to remove later. Clean filters significantly effect the robot’s efficacy.

Quick rinse after each use

1. Open the filter cover.
2. Upon opening the filter cover, the handle will lift automatically.
3. Lift the basket.
4. Open the latch to release the bottom lid.
5. Clean the filter basket with a hose, inside and outside the basket.

Periodic filter cleaning – Recommended about once a month
Dismantle the filter panels of the outer basket, with the following steps:

1. Dismantle the panels; start by pressing the plastic frame near the number on panel 1, using your thumbs.
2. Continue to dismantle the panels in order: 2 —> 3 —> 4.
3. Clean the filter panels with a hose.
4. Assemble the filter panels according to the following order: Panel 4 —> 3 —> 2 —> 1.
5. Insert the complete filter basket, and close the filter cover.

Cleaning the impeller
If you notice debris trapped in the impeller (underwater propeller):

For your safety, make sure the power supply is unplugged to prevent injury and damage.
Clean the debris trapped in the impeller, according to the following steps:

1. Unplug the power supply to prevent injury.
2. Lift the filter cover and remove the filter basket.
3. Squeeze 2 black tabs together to remove the exhaust manifold. Pull it towards the filter basket niche.
4. Clean the impeller. Return the manifold until it clicks, then place the filter basket back in its niche.

Periodic general maintenance – Recommended about once a week

• When the blue cable is wet, spread it flat and straight in the yard, and allow it to dry for at least five hours to avoid twisting of the cable.
• Wash the robotic pool cleaner with fresh water, to reduce damage caused by the chemicals in the pool water.

OFF-SEASON STORAGE
