BWT D400 / D500 / D600 Robotic Pool Cleaners

Introduction

System overview
The robotic cleaner sweeps the pool floor and walls, collecting dirt and debris in its internal filters. This user manual explains how to operate the robotic cleaner, including cleaning, maintenance, and storage procedures. This manual reviews several different models with variations.

Robotic cleaner operation
After the robotic cleaner is placed in the pool and activated, it operates according to its program. It moves along the floor and walls of the pool, covering the entire area. When it has finished its program, it remains inactive on the pool floor, and power will automatically shut off. It is not recommended to stop the pool cleaner before the cycle ends.

Note: Wall climbing is an optional feature. When enabled, the robotic cleaner climbs the wall at intervals according to its internal program (only D500 & D600). Its ability to climb over stairs in a swimming pool is subject to stair geometry and material.

Operating conditions
The robotic cleaner is intended for use in residential swimming pools only under the following conditions: (1) Recommended water temperature: 22°C-32°C (72°F-90°F). (2) Water pH: 7.2 - 7.6. (3) Chlorine level: The pool is maintained according to the pool manufacturer's instructions (Recommended Chlorine level: 2-4 ppm). Note: Failure to maintain the pool according to the recommended operating conditions could prevent the robotic cleaner from functioning properly.

Components

The system includes the following components:

• Power cable
• Power supply (control unit)
• Trolley (for D500/D600 models)
• Robotic pool cleaner

Operation

Placement of the Power Supply
(1) Place the power supply at least 3.6 meters / 11.8 feet from the pool and at least 3.6 meters / 11.8 feet above the surface. CAUTION: The power supply is not water resistant; it must not be exposed to water or direct sunlight.

(2) Press the plastic snap on the zip ties to release the floating cable. Use as much cable as needed into the water.

Before placing the cleaner unit in the water
(1) Ensure there are no people in the pool. (2) Ensure the filters are clean. (3) Ensure the pool conditions are met (refer to "Operating Conditions").

Placing cleaner in the water
(1) Unroll the floating cable. It is recommended to extend a length of cable equal to the pool's diagonal size plus an additional two meters. Smooth out any coils or twists in the cable. Roll any extra cable outside the pool near the power and control unit. (2) Place the cleaner unit in the pool. (3) Let it sink to the bottom of the pool. Do not start operation before the robotic cleaner is settled on the pool floor. (4) Connect the floating cable to the socket located on the power and control unit.

CAUTION: Operating the cleaner out of water causes immediate severe damage and results in loss of warranty.

Water Quality Indicators:
- Chlorine: 2-4 ppm - pH: 7.2-7.6 - Temperature: 13°C-35°C (55°F-95°F) - NaCl (Salt): 4000 ppm (max) - No Swimming: ??

Note: Please allow your robotic pool cleaner to absorb water for approximately 20 minutes. You may turn on the cleaner when it reaches the floor.

Starting the Robotic Cleaner

Connect the power supply to the wall socket. The on/off button is lit, and the robotic cleaner starts its cleaning program. If the power and control unit is already connected to the AC socket, the on/off button flashes to indicate the robotic cleaner is in standby mode. Press the Operation button. The on/off button turns on, and the robotic cleaner starts the cleaning program.

Note: When the Full Filter Indicator light is on (optional in some models), the filters must be cleaned before replacing the unit in the pool.

Cleaning Cycle

During the cleaning cycle, the cleaner:

• Moves across the pool floor picking up dirt and debris.
• Changes direction and rotates automatically according to the selected program.
• Climbs the pool walls every few minutes, as set in its internal program.

Note: The robotic cleaner might occasionally stop moving for a few seconds. This is part of normal operation, not a malfunction.

Stopping Robotic Cleaner Operation

The robotic cleaner moves automatically to 'standby' after every cleaning cycle, and the on/off button starts flashing. To stop the cleaner operation during a cleaning cycle, press the operation button once. The on/off button starts flashing, and the cleaner is in standby mode.

Pulling Cleaner Unit Out of the Water

• (1) Unplug the floating cable from the power supply.
• (2) Pull the floating cable until the unit is close enough to reach the handle.
• (3) Using the handle, lift the cleaner out of the pool.

CAUTION: Do not use the floating cable to lift the cleaner unit out of the water.

Power Supply Indicators

• On/Off: Indicates the power status.
• Full filter indicator: Alerts when filters need cleaning.
• Long press for short cycle: Functionality for initiating a shorter cleaning cycle.
• Bluetooth: Indicates Bluetooth connectivity status.

Maintenance and Storage

Cleaning the filters
The two filters must be cleaned after each cleaning cycle: (1) Release the filter and pull it out of the cleaner unit. (2) Open the filter case. (3) Spray water on the outer sides of the filter and then spray water towards the inner side of the filter to clean all the dirt and debris. (4) Reinsert the filter back into its location until a click is heard to secure the filter in place.

Storing the robotic cleaner
Follow these instructions to store the robotic cleaner when not in use: (1) Disconnect the power cord from the wall outlet. (2) Disconnect the floating cable from the power supply. (3) Spread out the floating cable and roll it. (4) Wash the cleaner unit interior space with fresh water and let it dry. (5) Roll the floating cable and place it on the cleaner unit. Caution: Do not roll the floating cable on the handle of the cleaner unit. (6) Store the robotic cleaner components in a dry, closed location. (7) Verify that the supply is not exposed to water.

Checking water outlet propeller
It is recommended to periodically clean debris and hair from the propeller of the water outlet: (1) Remove the filters. (2) Remove the screws that hold the water outlet cover. (3) Remove the water outlet cover. (4) Clean any hairs, dirt, or debris. (5) Return the cover and fasten it with the screws. (6) Reinsert the filters.
