Característiques clau

• Quick Release Check Valve: Facilitates fast and efficient servicing without needing to remove the condensate line.
• Integrated Safety Switch: Can be wired to shut down equipment or activate a high-level alarm, preventing overflow.
• Capacitat de bombament: Capable of pumping up to 125 gallons per hour.
• Voltage: Funciona a 115 volts.

2. Informació de seguretat

ADVERTIMENT: To reduce the risk of electric shock, always disconnect power to the pump before performing any service or maintenance.

• Ensure the pump is installed by a qualified technician in accordance with all local electrical and plumbing codes.
• No feu funcionar la bomba amb un cable o endoll danyats.
• Do not pump flammable liquids or chemicals. This pump is designed for water condensate only.
• Ensure the pump is installed on a level surface to ensure proper operation.
• Mantingueu els nens i el personal no autoritzat allunyats de la bomba durant el funcionament.

3. Configuració i instal·lació

Proper installation is crucial for the reliable operation of your condensate pump.

3.1 Muntatge de la bomba

• Place the pump on a firm, level surface near the condensate source.
• Ensure there is adequate space for maintenance and ventilation.

3.2 Condensate Inlet Connection

• Connect the condensate drain line from your equipment to one of the inlet ports on the pump reservoir.
• Use appropriate tubing and clamps to ensure a watertight seal.

3.3 Discharge Line Connection

• Connect a discharge tube (typically 3/8" or 1/2" ID) to the pump's discharge outlet.
• Route the discharge line upwards to a suitable drain, ensuring it does not exceed the pump's maximum lift height (16 feet for this model).
• Avoid kinks or sharp bends in the discharge line.

3.4 Connexió elèctrica

• The pump requires a 115-volt, 60 Hz power supply.
• Connecteu la bomba a una presa de corrent amb connexió a terra correcta.
• Safety Switch Wiring: The integrated safety switch has normally open (NO) and normally closed (NC) contacts.
  • For equipment shutdown: Wire the NC contacts in series with the low voltage thermostat circuit of the HVAC unit. When the water level rises too high, the switch opens, shutting down the equipment.
  • For high-level alarm: Wire the NO contacts to an external alarm system. When the water level rises too high, the switch closes, activating the alarm.

4. Instruccions de funcionament

The Mars 21786 condensate pump operates automatically.

• Once properly installed and connected to power, the pump will activate when the condensate level in the reservoir reaches a predetermined height.
• The pump will then discharge the condensate through the discharge line until the water level drops, at which point it will automatically shut off.
• The pump is designed for continuous duty within its specified capacity of 125 gallons per hour.

Prova Inicial

After installation, pour a small amount of water (approximately 1-2 liters) into the pump's reservoir to verify proper operation. The pump should activate, discharge the water, and then shut off. Check for any leaks.

5. Manteniment

Un manteniment regular garanteix un rendiment òptim i allarga la vida útil de la bomba de condensats.

5.1 Cleaning the Reservoir and Float Switch

• Freqüència: Inspect and clean every 3-6 months, or more frequently in dusty environments.
• Procediment:
  1. Desconnecteu l'alimentació de la bomba.
  2. Disconnect the inlet and discharge lines.
  3. Remove the pump cover (if applicable) or access the reservoir.
  4. Clean the inside of the reservoir and the float switch mechanism with a mild detergent and water. Remove any sludge, mold, or debris.
  5. Esbandir bé i tornar a muntar.

5.2 Quick Release Check Valve

• The quick release check valve allows for easy inspection and cleaning.
• To service, simply twist and pull the check valve assembly from the discharge outlet. Clean any debris and reinsert.

5.3 Inspecting Lines

• Periodically check inlet and discharge lines for blockages, kinks, or leaks.
• Assegureu-vos que totes les connexions siguin segures.

6. Solució De Problemes

Before attempting any repairs, always disconnect power to the pump.
