- Environmental Conditions: Do not operate the device in explosive atmospheres or where flammable liquids or gases are present.
3. Product Features
The Ortis KJ-033 controller offers several features for reliable water level management:
- Dual Stainless Steel Sensors: Anti-corrosion sensors for accurate water level detection.
- Adjustable Sensor Range: Sensors can be adjusted from 1/2 inch to 20 inches to define high and low water levels.
- Multiple Operating Modes: Supports Drain Mode (for emptying) and Water Mode (for filling).
- LED Indicators: Visual feedback for power, load status, and alarm conditions.
- Overload Protection: Integrated protection for connected pumps.
- Mute Function: Allows silencing of the alarm.
- Wide Application: Suitable for sewage pits, fish tanks, water tanks, and other water management systems.

4. Setup and Installation
Proper installation is crucial for the reliable operation of the controller.
4.1 Controller Mounting
The controller unit should be mounted in a dry location, above the maximum water level, and within reach of a grounded power outlet.
- Screw Mounting: Use appropriate screws and anchors to secure the controller to a wall or stable surface through the mounting tabs.
- Suction Cup Mounting: For temporary or non-permanent installations, a suction cup can be used to attach the controller to a smooth, clean surface.
Figure 4.1: Controller Installation Methods.
4.2 Sensor Installation and Adjustment
The dual sensors detect the high and low water levels. Their position determines the operating range of your pump.
- Sensor Placement: Position the sensors vertically in the water, ensuring they are securely fastened and will not move. The lower sensor defines the 'low' water level, and the upper sensor defines the 'high' water level.
- Adjustable Range: The sensors can be adjusted along their cables to set the desired water level range, from 1/2 inch to 20 inches apart. Ensure both sensors are submerged at the desired 'on' level and the lower sensor is exposed at the desired 'off' level for drain mode, or vice versa for water mode.
- Cable Management: Route sensor cables to prevent entanglement or damage.
Figure 4.2: Adjustable Sensor Installation.
4.3 Electrical Connection
- Power Plug: Plug the controller's power cord into a grounded 220V or 110V AC outlet.
- Pump Connection: Plug your sump pump or other load device into the outlet on the front of the controller. Ensure the pump's power requirements do not exceed the controller's output capacity (15A, up to 2HP).

5. Operating Instructions
The controller features a simple interface for selecting operating modes and managing alarms.
Figure 5.1: Control Panel Overview.
5.1 Mode Selection
Use the 'Drain' and 'Water' buttons to select the desired operating mode:
- Drain Mode: (LED indicator 'Drain' illuminates) In this mode, the controller activates the pump when the water level reaches the upper (high) sensor and deactivates it when the water level drops below the lower (low) sensor. This mode is typically used for emptying sewage pits or sumps.
- Water Mode: (LED indicator 'Water' illuminates) In this mode, the controller activates the pump when the water level drops below the lower (low) sensor and deactivates it when the water level reaches the upper (high) sensor. This mode is typically used for replenishing water in fish tanks or water tanks.
5.2 Power and Operation Switch
The main switch controls the power and operational state of the connected load:
- AUTO: (LED indicator 'AUTO' illuminates) The controller operates automatically based on the selected mode (Drain or Water) and sensor readings.
- OFF: (LED indicator 'OFF' illuminates) The connected pump is turned off, regardless of water levels.
- ON: (LED indicator 'ON' illuminates) The connected pump is continuously turned on, regardless of water levels. Use this for manual override or continuous operation.
5.3 Mute Function
Press the 'Mute' button to silence any active alarms. The 'DisAlarm' LED will illuminate when the alarm is muted.

6. Maintenance
Regular maintenance ensures the longevity and reliable operation of your Ortis controller.
- Sensor Cleaning: Periodically inspect and clean the stainless steel sensors to remove any buildup of debris, algae, or mineral deposits that could affect their accuracy. Disconnect power before cleaning.
- Cable Inspection: Check all cables and connections for signs of wear, damage, or corrosion. Replace any damaged components immediately.
- Controller Unit: Keep the controller unit clean and dry. Avoid exposing it to direct sunlight or extreme temperatures.
- Test Operation: Periodically test the controller's operation by manually raising or lowering water levels to ensure the pump activates and deactivates as expected in the selected mode.
7. Troubleshooting
Refer to the table below for common issues and their solutions.
| Problem | Possible Cause | Solution |
|---|---|---|
| Pump does not turn on/off automatically. | 1. Controller not in AUTO mode. 2. Sensors are dirty or improperly positioned. 3. Pump is not plugged in or is faulty. | 1. Ensure the switch is set to 'AUTO'. 2. Clean sensors and verify their high/low positions. 3. Check pump connection and functionality. |
| Alarm sounds frequently. | 1. Water level not reaching desired sensor within expected time. 2. Sensor malfunction. 3. Alarm sensitivity setting (if applicable, check product documentation). | 1. Check pump operation and water flow. Adjust sensor positions if needed. 2. Inspect sensors for damage or debris. Replace if faulty. 3. Use the 'Mute' button temporarily. Consult manufacturer for alarm logic details. |
| Controller has no power. | 1. Power cord unplugged. 2. Outlet has no power. 3. Internal fuse blown. | 1. Ensure power cord is securely plugged in. 2. Test the outlet with another device. Check circuit breaker. 3. Contact customer support for assistance. |
| Pump runs continuously in AUTO mode. | 1. Sensor stuck in 'on' position (e.g., upper sensor always wet in Drain Mode). 2. Controller malfunction. | 1. Clean and reposition sensors. Ensure they can freely detect water level changes. 2. Disconnect power and reconnect. If issue persists, contact support. |
