TROUblESHOOTING GUIDE FOR DElTa ECOPOD-NFIXED FIlM WaSTEWaTER TREaTMENT SYSTEM

Procedure for Visual and Olfactory Evaluation of System

  • 1.

    Check to be sure that the air system is working properly. This will be evident in the reactor as the liquid will be forcefully agitated. A septic (rotten egg) odor could mean that the sys- tem is not getting enough air. If the air system is not working, partially working or working very little (slight bubbles), check the following:

    • a.

      Check to be sure the air pump is working.

      • Check timer if one is used;

      • Bypass timer and temporarily connect directly to source;

      • Check the electrical source;

      • If electrical source is okay, check service guide on pump unit for troubleshooting information;

      • Wash air filter on pump;

      • Consult manufacturer for servicing information.

    • b.

      Check to be sure tank is not severely out of level. Air follows a path of least resistance. The pressure differences can be enough to prevent or restrict air flow.

    • c.

      Check for broken or cracked air lines both outside and inside the tank.

    • d.

      Ants will destroy an air pump. Check to see if there is an ant nest around the air pump.

    • e.

      Air pump should be protected from rising water.

    • f.

      Always check to see if inlet and outlet lines are correctly installed.

Internal Assembly Malfunction

  • 1.

    Primary treated wastewater from the primary tank should not enter directly into the dilution zone because of improperly installed or loose seals or gaskets where pipe goes through the tank wall. Check the size of holes to be sure that there is no clearance for matter to pass through the wall around the piping.

  • 2.

    Check to be sure all internal piping and connections are tight.

Design Overload

  • 1.

    The system could be hydraulically overloaded (there is too much water going through the system for the size of the system).

  • 2.

    The system could be biologically overloaded (there is too much waste for the size of the system).

Improper Installation Or Settling

  • 1.

    You should follow the manufacturer installation procedures very carefully.

  • 2.

    Where settling is common, approximately 2 inches of sand should be placed and tamped in the bottom of the hole.

  • 3.

    Proper installation is the first step in preventing call backs for service problems.

  • 4.

    Whenever possible, it is important to spend time with the homeowner. Be sure they have an operations book. A few minutes invested in the beginning will avoid service calls later.

No Harsh Chemicals Should Be Put Into The System

  • 1.

    Water in the reactor tank should be the relatively clear in both the reactor and dilution zone. Blue or gray/blue water indi- cates heavy use of detergents or other chemicals. If water appears sudsy, there is too much detergent being used.

  • 2.

    Water in the dilution zone should be clear. Water is dis- charged into the discharge tee at a minimum of 6-8 inches below water surface. You MAY not be able to see clear water by looking into the tank. Samples must be taken at the sample port.

  • 3.

    Oils and grease should be kept to a minimum. Grease tends to form in white balls.

Trouble Shooting Electrical System

  • 1.

    Air pump does not run:

    • a.

      Check main service for power;

    • b.

      Check and/or replace fuse with same rating as is in control panel.

  • 2.

    Alarm does not occur when air pump is off:

    • a.

      Malfunctioning pressure-switch – replace.

    • b.

      Malfunctioning light or buzzer – replace.

  • 3.

    Alarm occurs continuously even when air pump is running:

    • a.

      Air-leak in main air system or air tubing to pressure switch

      • repair leak or replace air line.

    • b.

      Malfunctioning pressure-switch – replace.

    • c.

      High water level in tank – inspect for cause.

    • d.

      Short in float switch wire or float switch – repair or replace.

NOTE: All replacement parts are available from your local dealer.

n CAUTION: Electrical shock or hazard may occur if unit is not serviced properly. The manufacturer recommends that a licensed electrician be called when electrical problems occur.
