• Use a plumber's snake to clear the drain line to the outside of your home.

• Reinstall the float switch and restore power to the air conditioner.
• Pour one cup of liquid bleach through the drain line every six months to keep the drain line clear of algae.

Operating tips for your Weatherking heating and cooling combined unit

• Never operate the heating and cooling combined unit without a clean air filter properly installed. Inspect the air filter monthly and replace the air filter when it's dirty. A clogged air filter will increase operating costs and cause cooling problems.
• Keep supply air register vents and return air vents clear. Don't allow drapes, furniture, toys or other items to block supply or return air vents. Clean air vent louvers when they're dirty.
• Keep the outdoor condenser unit clear of shrubs, weeds grass and debris. Maintain a 1-foot clearance around the condenser unit for proper airflow.
• Jiggling the wall control thermostat causes rapid cycling in the control system and this can cause damage to air conditioner components. Don't move the temperature selector on the thermostat for at least 5 minutes between adjustments.
• Running the blower fan continuously minimizes temperature differences inside supply ducts and can lead to greater comfort and cooling efficiency. Consider running the blower fan constantly during hot summer months.
