How to Use a Roof-mounted Mobile Toilet

The use of a roof-mounted mobile toilet requires following standardized procedures for installation, connection, functional operation, and maintenance and cleaning, while also selecting the appropriate model based on the usage scenario. The specific steps are as follows:

I. Installation and Connection

1. Placement and Fixation: Position the mobile toilet in a stable area on the rooftop, ensuring that the bottom makes firm contact with the ground to prevent shaking or tilting. If wind protection is required on the rooftop, use fixing devices (such as ground anchors or weight blocks) to secure it.
2. Pipe Connection:
   • Sewage Pipe: Connect to a temporary drainage outlet or a sealed sewage collection container. Wrap sealing tape around the joints or use specialized clamps to prevent odor leakage.
   • Water Inlet Pipe: Connect to a clean water source (such as a water tank or municipal water supply). Open the valve to fill the clean water tank to the specified level, avoiding running the pump with an empty tank to prevent damage.
3. Power Supply: Plug in the power cord, ensuring a stable voltage (usually 220V), and avoid sharing the socket with other high-power appliances. Check the sealing of all joints, especially where the sewage pipe connects to the sewage tank.

II. Functional Operation

1. System Startup: Press the power switch on the control panel. When the indicator light comes on, the system enters standby mode. If equipped with a heated seat or automatic deodorization function, activate the preheating or deodorization mode in advance.
2. Toilet Use and Flushing:
   • After using the toilet, press the flush button (marked with a water droplet icon). The built-in pump draws water from the clean water tank into the toilet bowl to complete the flush.
   • Dual-flush Function: Some models support a small water volume (1-2L) for urination and a large water volume (3-5L) for defecation. Choose the appropriate option based on needs to conserve water.
3. Additional Functions: High-end models allow adjustment of the seat temperature, air-drying intensity, or deodorization intensity via buttons. Turn off unnecessary functions after use to reduce energy consumption.

III. Maintenance and Cleaning

1. Sewage Tank Handling:
   • When the sewage tank is nearly full (some models have a liquid level alarm), turn off the power first, then unplug the sewage pipe.
   • Pull out the sewage tank horizontally, empty its contents, and rinse the inside with clean water. Disinfect it monthly with a specialized cleaner, paying special attention to cleaning any solid residues from the shredding blades (if present).
2. Clean Water Tank Maintenance: Clean the clean water tank once a week to prevent algae growth. If not in use for an extended period, empty the tank and keep it ventilated and dry.
3. Daily Inspection: Regularly check if the sewage pipe is bent or if the power cord is damaged to prevent flushing failures due to pipe blockages or electrical faults.

IV. Precautions

1. No Foreign Objects: Avoid throwing items other than toilet paper (such as feminine hygiene products or diapers) into the toilet bowl to prevent pipe blockages or damage to the shredding device.
2. Freeze Protection: In cold environments, empty the water from the clean water tank and sewage tank or add antifreeze to prevent the pump from cracking when the water temperature drops below 0°C.
3. Model Selection Advice: For short-term events, a simple model (relying on chemical agents to decompose waste) may be suitable; for medium- to long-term use, a water-flush model (requiring a water source or a built-in water tank) or an ecological model (using microbial degradation technology without the need for external sewage pipes) is recommended.
