This document describes the DiversiTech Condensate Pump, a device designed to automatically remove condensate water from various appliances. These appliances typically include air conditioners, high-efficiency furnaces, and de-humidifiers. The pump is engineered to manage the water that collects from these systems, ensuring efficient operation and preventing potential issues caused by water accumulation.
The core function of the condensate pump revolves around its integrated tank. This tank serves as a collection point for the condensate water. Once the water level within the tank reaches a predetermined threshold, the pump automatically activates. It then proceeds to pump the collected water to a remote location for proper disposal. As the tank empties and the water level drops, the pump automatically deactivates, conserving energy and preventing unnecessary operation. This automatic on/off cycle is a key feature, allowing for hands-free maintenance of condensate levels.
A notable usage feature of this pump is its ability to lift water to its rated height. This capability is crucial for installations where the disposal location is elevated relative to the pump. To prevent water from flowing back into the tank once the pump shuts off, a check valve is integrated into the system. This ensures that the pumped water remains in the discharge line and does not return to the tank, maintaining efficiency and preventing re-pumping of the same water.
For user convenience and operational monitoring, the pump is outfitted with indicator lights. These lights provide visual feedback on the pump's status, including power availability, motor operation, and a high water (alarm) condition. These visual cues allow users to quickly assess the pump's state and identify any potential issues at a glance.
The pump also incorporates a safety switch, which activates if the water in the tank reaches an overflow condition. This overflow safety switch can be connected to the appliance itself, allowing it to automatically shut off the appliance if a high water condition occurs. This prevents potential water damage and ensures the safety of the system. Additionally, the safety switch has an alarm terminal that can be optionally connected to an audible alarm or a remote indicator light. This provides an additional layer of notification, alerting users to a trouble condition even if they are not in direct proximity to the pump. The safety switch operates independently of the pump's power, ensuring its functionality even in the event of a power interruption to the pump.
Regarding installation, the pump is designed for indoor use and should be stored in a clean and dry location. It must be placed on a solid, level surface or floor. The pump is equipped with rubber feet, which serve to reduce operational noise and keep the unit securely in place during operation. It is important to note that the pump should not be used in environments where spraying or standing water is present, as this could lead to an electrical shock hazard. Furthermore, it is not suitable for use in Class I or Class II locations, which involve explosive gas or dust environments. Proper ventilation is also critical; the pump is air-cooled, and its air vents, located on the top or sides of the housing, must not be covered. The pump can operate continuously as long as these vents remain unobstructed.
The pump features metal mounting tabs, allowing it to be screwed to a wall or equipment side panel. The screw-to-screw distance for mounting is 8 inches. When mounting into drywall or concrete, appropriate anchors must be used to provide sufficient support. The pump's top is reversible, offering flexibility in installation to allow easy access to the pump outlet, pan tab tray, or power connection as needed.
For condensate input, there are four inlet holes located on the top deck of the pump. Flexible vinyl tubing or PVC can be connected to any of these inlets. Pop-out covers are provided for unused inlets, and it is essential to cover these to prevent debris or insects from entering the pump. Tubing installed into the inlet holes must be straight and should not bend inward, as this could interfere with the pump or float mechanism. When using rigid tubing, the end should be cut at an angle to ensure free drainage and prevent blockage by the tank bottom. It may also be beneficial to install a "P" or "U" trap between the AC unit and the condensate pump. This creates a liquid barrier that prevents airflow from the air conditioner, which can be wasteful and contribute to algae growth.
The pump's outlet features a combination barb-type fitting and a check valve. This fitting accommodates 3/8-inch flexible vinyl tubing, which should be secured with a screw-type hose clamp. The outlet tubing should be routed upwards and away from the pump, avoiding compression or kinking. For optimal performance, the shortest possible route to the building exterior or other drain location is recommended. A longer downward tubing section can assist in siphoning condensate from the tank, thereby speeding up the pump's emptying time.
Maintenance features include a dispenser for DiversiTech Pro-Treat pan treatment tablets. These tablets help keep the pump, tank, and outlet tubing free of slime. The dispenser can hold multiple tablets for extended treatment.
For electrical connections, the pump requires a properly grounded outlet that can supply power exceeding the requirements listed on its nameplate. The use of extension cords should be avoided. The pump needs a continuous power source and should not be connected to switched outlets or other power supplies that might be inadvertently or automatically turned off.
Regular maintenance is crucial for the pump's longevity and efficient operation. Before any maintenance, the power must always be disconnected. The pump and deck can be removed from the tank by pushing tabs on the tank sides and lifting the pump cover. Periodically, the pump tank should be inspected for accumulated dirt or sludge. It should be cleaned with soap and warm water only, avoiding solvent cleaners. The check valve can be removed for cleaning or replacement by unscrewing it with a 9/16 wrench. Inlet and outlet piping should also be cleaned. Slime or debris in tubing can be cleared using tools like a Wagner brand Gallo Gun with Swoosh cartridges. After cleaning, Pro-Treat Tabs should be added to the tablet tray. Finally, the system should be reassembled and checked for correct operation.
The installation and operation of the pump must conform to all requirements of the National Electrical Code (NEC) and any applicable local codes. Homeowners should be instructed on the pump's general operation, how to add Pro-Treat tablets, and to monitor the ALARM LED for system trouble.
