The Hartell KT15 and KL20 series condensate pumps are designed to automatically collect and remove water produced from air conditioner evaporative coils and/or gas-condensing furnaces. These pumps are engineered for long, trouble-free service, built with high-quality workmanship and materials. Each pump undergoes thorough inspection and testing before being carefully packaged to ensure safe delivery and operation. Upon receipt, users should inspect the pump for any damaged or broken parts and notify the vendor if damage is detected.
The pump can be mounted on a wall, the air conditioner case, or the floor. It is crucial that the pump is level, and its inlet must be positioned below the lowest drain point of either the coil or furnace. For wall or case mounting, the provided mounting tabs on the reservoir sides should be used to secure the pump.
Flexible tubing or pipe should be run from the evaporator and furnace to the pump, inserting it into the drain inlet hole. Care must be taken to ensure the pipe does not interfere with the float. The inlet pipe should be cut at an angle to prevent it from closing off against the bottom of the pump.
For discharge, 3/8" ID tubing should be connected to the barbed check valve. This tubing should extend straight up as high as necessary, but not past the pump's head/GPH rating. Kinking the tubing must be avoided as it will block the flow. From its highest point, the discharge tubing should slope downward to a point above the drain, then turn down and extend to a point below or level with the bottom of the condensate pump. If a downward slope is not possible, an inverted "U" trap should be created directly above the pump at the highest point.
The power cord should be connected to the proper voltage as indicated on the motor nameplate. It is essential to connect the pump only to a source of constant power, not an intermittent source like a fan or limit control circuit. The pump is supplied with a grounding type plug and must be connected to a properly grounded receptacle to reduce the risk of electrical shock. All wiring must comply with local codes.
The leads of the auxiliary safety switch should be connected to the thermostat control circuit of the air conditioner/furnace. This feature will disrupt the thermostat demand in a high water condition. However, if cooling or heating requirements are a necessity, this demand disruption should not be utilized; instead, an alarm system should be used with the auxiliary switch.
Once properly installed, the Hartell condensate pump operates automatically. Water collects in the reservoir, and when the float rises to a pre-set point, the pump activates to discharge the water. As the water level drops, the float turns off the motor at another pre-set point. Under normal circumstances, the pump requires minimal maintenance for efficient operation.
In cases of extreme algae formation, unplug the pump and fill the reservoir with a commercially available algaecide. Follow the product directions for destroying the algae. After the recommended waiting period, dump the algaecide from the reservoir. Rinse with water and repeat if necessary. Be careful not to clog the check valve when restarting the pump after cleaning.
Under most circumstances, the pump requires little maintenance. If problems occur, refer to these instructions:
Hartell KT15 and KL20 series condensate pumps are guaranteed to be free from defects in workmanship or materials and to function satisfactorily, when properly installed, for a period of one (1) year from the date of installation. Hartell will replace, without charge, any defective Hartell product upon examination at their factory if returned within the guarantee period, with transportation charges prepaid. This guarantee does not apply if the product has been misapplied or mechanically damaged. Hartell assumes no liability for resultant damages of any kind arising out of the use of its products.
