GETTING STARTED

Charging the battery
IMPORTANT NOTE: Fully charge the pool vacuum (about 6 hs) before using it for the first time.
WARNING!

• Use only the original external adaptor and charging base provided.
• Make sure the pool vacuum and the charging contact plates are clean and dry before set-up and charging. (TIPS: Use a cotton bud to dry the charging contact plates)
• Charging must be done indoors, in a well-ventilated area away from sunlight, children, heat, ignition sources, and with an ambient temperature between 5˚C (41˚F) and 35˚C (95˚F).
• Never use the external adaptor and charging base if any damage is detected.
• The charging contact plates are waterproof. However, remnants of water on the contact plates could result in natural occurrence of stains (a byproduct of chemical reaction between water and electric currents). Otherwise, the stains can be removed by light scrubbing with a cotton bud soaked with juice of lemon or vinegar.
• Make sure that the pool vacuum is turned off prior to charging.

1. Place the unit on a flat surface. Make sure the pool vacuum is off by turning the power ON/OFF switch to the OFF position prior to charging.

2. Turn the locking knob (on each side) anticlockwise until it points to the green dot marking (unlock position) to unlock and release the rear body from the transparent canister.

3. Place the rear body (upside down – power on/off switch face up) on a flat surface. Align and slide the hook of the charging base onto the side notch at the bottom of the rear body until it stops. Make sure their contact plates are properly in contact. Plug the female jack of the external adaptor into the charging port at the end of the charging base.

4. Connect the external adaptor to the power source. Once the pool vacuum begins charging, the indicator light on the external adaptor will turn red. Normally, it takes about 5-6 hours to reach a full charge. The indicator light will turn green when the pool vacuum is almost fully charged.
   NOTE: if the motor is generating noise, ensure “OFF” is selected on the power switch.
   Immediately disconnect the external adaptor from the power source if you detect any of the following:

   • Offensive or unusual odor
   • Excessive heat
   • Deformation, cracks, leaks
   • Smoke

5. When charging is complete, disconnect the external adaptor from the power source and detach the charging base from the unit and external adaptor.
   Normally, the pool vacuum can operate up to 40 minutes on a full charge (charged for 5-6 hours)

   • Note: Clean the filter regularly. Too much debris inside the filter will increase burden to the motor operation and then shorten the operating duration. To re-position the transparent canister (with the filter cone inside) to the rear body, make sure the locking knob on both sides is turned to the unlock position. Align the raised arch on both sides of the transparent canister with the locking knobs and then turn the knob clockwise until it points to the red marking to secure the assembly.

   • Attention: The case has one correct position only. The water-draining valve must be facing the bottom when holding the cleaner horizontally by the handle.

   • FACT: Rechargeable lithium-Ion battery is classified as a consumable item. It has a limited life and will gradually lose its capacity to hold a charge. Therefore, running time of the pool vacuum will gradually reduce through repeated charging and discharging in operation.

   • Once the lifespan of the battery reaches its end, refer to section “BATTERY DISPOSAL” for instructions regarding battery disposal

   • NOTE: Let the pool vacuum rest for 30 to 40 minutes before charging it again.
