2. Setup and Installation
Proper installation is crucial for the optimal performance and longevity of your condensate pump. Please follow these instructions carefully.
2.1 Unpacking and Components
Before installation, ensure all components are present:
- Condensate Pump x 1
- 20 ft Tubing x 1
- Safety Switch Wire x 1
- Zip Ties x 4
- Instruction Manual x 1
Figure 2: The package contents include the condensate pump, 20 ft tubing, safety switch wire, and four zip ties.
2.2 Placement
Install the condensate pump in a horizontal position. The integrated spirit level on the pump's top cover can assist in ensuring proper horizontal alignment.
Figure 3: The pump features a spirit level for horizontal placement, 1.1-inch I.D. water inlets with dust covers, and a 2/5-inch O.D. barbed water outlet with a built-in check valve.
2.3 Connecting Water Inlets and Outlet
The pump is equipped with four 1.1-inch I.D. water inlets, allowing connection to multiple pieces of equipment. These inlets come with dust covers. The 2/5-inch O.D. barbed outlet includes a built-in check valve to prevent water backflow. Connect the provided 20 ft tubing to the outlet and route it to a suitable drainage point.
2.4 Safety Switch Connection
The pump includes a safety switch function. Connect the provided safety switch wire to the designated metal joints on the side of the pump. This wire can be integrated into your HVAC system to automatically shut off the appliance in case of a potential overflow, preventing water damage. If you are unsure about connecting the safety switch, consult a professional.

3. Operating Instructions
The MSELTOS MD-TPS-20 condensate pump operates automatically, detecting water levels and initiating pumping as needed.
3.1 Automatic Drainage
The pump automatically detects the water level in its 0.6-gallon reservoir. When the water reaches a certain level, the pump activates to remove the condensate, preventing overflow. It will automatically stop once the water level drops.
Figure 5: The pump utilizes a float switch and Hall sensing plate for automatic start/stop operation, maintaining a low working noise level below 30 dB.
3.2 Indicator Lights
The pump features three indicator lights on its panel to communicate its operational status:
- Green Light (READY): Indicates that the pump is connected to power.
- Yellow Light (PUMPING): Indicates that the pump is actively working and draining water.
- Red Light (ALARM): Indicates a risk of overflow. An audible alarm will also sound simultaneously.
Figure 6: The three indicator lights (Green: Power, Yellow: Pumping, Red: Alarm) provide visual feedback on the pump's status.
4. Maintenance
Regular maintenance ensures the efficient operation and extends the lifespan of your condensate pump.
4.1 Reservoir Cleaning
The 0.6-gallon reservoir is made of specially treated plastic designed to resist dirt accumulation. However, periodic cleaning is recommended to prevent clogging and ensure proper function. Disconnect power before cleaning. Remove the top cover and clean the inside of the reservoir with mild soap and water. Rinse thoroughly.
4.2 Tubing Inspection
Periodically inspect the 20 ft drainage tubing for any kinks, blockages, or damage. Ensure the tubing remains clear to allow for unobstructed water flow.
