This document outlines the operational and programming instructions for a big massage bathtub, focusing on its various functions, usage features, and maintenance aspects.
The bathtub system is designed for a comprehensive user experience, offering constant temperature control, preset heating, and real-time display of water temperature. It incorporates three surfing pumps, one circulation pump, and a blower, all contributing to a dynamic and customizable hydrotherapy experience. The lighting system features color-changing capabilities, allowing users to synchronize or fix colors according to their preference.
The device's core functions revolve around temperature management, water circulation, and entertainment.
The system provides constant temperature control, allowing users to set a desired water temperature. It includes a preset heater function, which can be programmed to activate at specific times. The LCD displays the current water temperature and allows for adjustments. The system also features a frozen preventing control, which automatically activates the heater and circulation pump when the water temperature drops below 5°C and turns them off at 10°C, ensuring the system's integrity in colder conditions. Temperature units can be shifted between Fahrenheit and Celsius.
The bathtub is equipped with three surfing pumps and one circulation pump, offering various hydrotherapy options. A blower is also integrated, enhancing the massage experience. The system includes a "Long Circulation Cleaning" function, which can be programmed to run at specific times and durations, ensuring the cleanliness of the water circulation system. During this cleaning process, the surfing pumps, blower, and ozone generator (if present) operate for set intervals to thoroughly clean the system.
The device features a built-in radio with CD input, capable of storing up to 10 channels. Users can search for radio frequencies, adjust the volume, and switch between radio and CD modes. The system allows for memorizing radio frequencies to specific channels (0-9).
The bathtub includes a bottom lamp with color-changing capabilities. Users can turn the lights on/off, cycle through changing colors, or fix a specific color.
The system incorporates safety features such as a "LV Protect" (Low Voltage Protect) and "P Control" (Power Control). It displays "E1" if the sensor is open or short-circuited. Power loss memory ensures that all settings are retained after a power interruption.
The bathtub's operation is primarily managed through a control panel with various buttons, each serving a specific purpose.
The system can be turned ON or OFF using the dedicated power button. Upon startup, the backlight illuminates, and the LCD displays the current time and temperature. The system can enter a "Waitting Mode" status, indicated by "---" on the radio frequency display, during which pre-heating and circulation cleaning can be initiated.
The control panel can be locked to prevent accidental changes. Pressing the "MEM LOCKED" button in "Waitting Mode" or after 30 minutes of inactivity will lock the system. Unlocking requires pressing the "MEM LOCKED" button twice.
In "Waitting Mode" with pre-heater and circulation cleaning shut down, users can set the time using the "TUNE-" (HOUR) and "TUNE+" (MINUTE) buttons. The hour adjustment range is 0-23, and the minute adjustment range is 0-59. The system automatically exits time-setting status after 6 seconds of inactivity.
The "Circulation Cleaning" function can be programmed to run once daily. Users can set the start time and continual duration of the cleaning cycle. The setting process involves pressing the "CYCLE" button to enter the setting status, then using "TUNE+" (MINUTE) and "TUNE-" (HOUR) to adjust the start time and duration. The minimum continuous cleaning time is 5 minutes, and the maximum is 19 hours and 55 minutes. All circulation cleaning settings must be performed in "Waitting Mode," and the circulation pump and ozone generator will not operate during the setting time.
Similar to circulation cleaning, pre-heating can be programmed once daily. Users can set the start time and continual duration of pre-heating, as well as the desired temperature. The setting process involves pressing the "PREHEAT" button to enter the setting status, then using "TUNE+" (MINUTE) and "TUNE-" (HOUR) to adjust the start time and duration. The minimum continuous pre-heating time is 5 minutes, and the maximum is 19 hours and 55 minutes. The temperature can be adjusted from 15°C to 45°C. All pre-heating settings must be performed in "Waitting Mode," and the pre-heating system will not operate during the setting time.
The constant temperature heating system can be activated either by the programmed pre-heating time or by pressing the "PREHEAT" button. The circulation pump runs continuously during constant temperature heating. The heater automatically turns off when the water temperature reaches or exceeds the set temperature (e.g., 36°C if set to 35°C) and restarts when the temperature drops below the set point (e.g., 34°C). If the temperature sensor is open/short, the auto-temperature control system will not function.
The blower can be turned ON/OFF using the dedicated "BLOWER °F/°C" button.
Dedicated buttons for "Pump1/2/3" control the respective surfing pumps.
Pressing the "C" button turns the "Long Circulation" function ON/OFF. When activated, the surfing pumps and blower operate for 30 seconds, and the ozone generator (if present) operates for 15 minutes. If any surfing pump or blower is already running, the ozone generator will automatically turn off.
The "ON/OFF" key for radio and CD is available in "Power-on" status. The first press turns on the radio, the second turns off the radio and turns on the CD, and the third turns off both. Volume can be adjusted using "TUNE+" (MINUTE) and "TUNE-" (HOUR). The "MHz/CH SET" button allows users to recall memorized radio frequencies or save the current frequency to a channel. The "MEM LOCKED" button is used to memorize the present radio frequency to a channel.
While the manual primarily focuses on operational aspects, some maintenance-related information is implicitly provided.
The "Circulation Cleaning" function is a key maintenance feature, designed to keep the water circulation system clean. By regularly running this program, users can prevent buildup and maintain hygiene within the bathtub's plumbing.
The "E1" error code for a sensor open/short circuit provides a diagnostic tool for identifying potential issues with the temperature sensor, allowing for timely troubleshooting and repair.
This feature acts as a protective measure against freezing, which can cause significant damage to the bathtub's plumbing and components. By automatically activating the heater and circulation pump in cold conditions, it helps prevent costly repairs.
The system will not allow water pumps, blower, and the constant temperature system to start if there is no water in the bathtub. This prevents dry running, which can damage the pumps and heater. The corresponding signal on the LCD will flash to alert the user.
It is explicitly stated that all pre-heating settings must be done in "Power OFF" status, with the spa just connected to the power supply. This is a crucial safety and operational guideline to ensure correct configuration.
The manual emphasizes that during all setting times for circulation cleaning and pre-heating, the circulation pump and ozone generator are not working, which is important for user awareness and safety during configuration.
In summary, the massage bathtub is a feature-rich device designed for comfort, convenience, and ease of use, with integrated systems for temperature control, hydrotherapy, entertainment, and essential maintenance.
