Durastill Model 42C

Note: Two separate float switch mechanisms are embodied in this distiller. One switch (S3) regulate the ON/OFF operation of the water solenoid valve. The other switch (S2) is a safety device that will shut off the heating element and the fan when the water level becomes too low. These switches are preset at the factory and should require no adjustment.

Evaporator tank will not fill with water automatically:

  1. Water solenoid valve switch is turned off.
  2. There is no water pressure at water solenoid valve inlet. (Make sure saddle valve is turned on. Check for kinks in plastic tubing.)
  3. Float inside evaporator tank is stuck.
  4. Float switch mechanism is incorrectly set*, or water level control switch (S3) is defective.
  5. Water solenoid valve is damaged.
  6. Circuit breaker (CB-3) is open.

* Refer to float switch adjustment instructions in manual.

Water solenoid valve will not shut off automatically:

  1. Float inside evaporator tank is stuck.
  2. Float switch mechanism is incorrectly set.*
  3. Water solenoid valve is damaged.

Distiller does not operate and indicator lamp (L1) is off and LED (L2) is off:

  1. Main power switch on unit is off.
  2. Line current (208 or 240V A.C.) is off or unit is not plugged in.

Distiller does not operate and indicator lamp (L1) is on and LED (L2) is off:

  1. Storage tank is full or storage tank control plug is not plugged into distiller control socket.
  2. Water level inside evaporator is too low.
  3. Float switch mechanism or Durastill storage tank is functioning improperly.*
  4. Circuit breaker CB3 is open.
  5. Relay coil is burnt out.
  6. Transformer is damaged.

Distiller does not operate, and indicator lamp (L1) is on and LED (L20 is on:

  1. Relay coil is burnt out.

Fan does not operate automatically:

  1. Fan switch is turned OFF. (Steam will be produced.)
  2. Water level inside evaporator is too low.
  3. Fan motor is bad. (Steam will be produced through condenser coils.)
  4. Circuit breaker CB1 or CB2 is open.

Fan operates but no water is produced:

  1. Thermostat button needs to be reset. Distiller must be cooled down before thermal switch can be reset. (This reset button is for your safety. It is designed to stop the unit from operating should the water level get too low.)*

    Note: Anytime the thermal protective switch needs to be reset it indicates that the float switch mechanism needs adjusting.

  2. Both heating elements are bad.
