CLEANING AUTOMATIC DRAW-OFF GREASE INTERCEPTORS

Since cleaning a "GT" interceptor is simple, fast and efficient, maintenance personnel will more likely follow the regular cleaning schedule. This is a distinct advantage over the conventional units which are frequently left unattended.

8000 GT Series When to Clean - The ideal time to clean is immediately after the interceptor has been heavily used.

Cleaning Frequency - The frequency of the draw-off cycle is determined by the use load factor of the interceptor. An ideal cleaning cycle can be set after the unit is in operation for several weeks. By observing the amount of grease used and the frequency of use, the operator can determine a logical cleaning cycle.

Cleaning Operation 8000 GT Series

  1. Unit in normal use has the line control valve open and semi-automatic draw-off valve closed. When cleaning is required, run a full stream of hot water through interceptor. It is preferable to have this water at 140° or higher, running for a period of at least two minutes.
  2. Turn off hot water running into the interceptor and wait for a period of three to five minutes for grease in the interceptor to liquefy.
  3. Semi-Automatic draw-off cycle can now be started. Close the line control valve.
  4. Open semi-automatic draw-off valve at top of the interceptor and place a container underneath this valve. Run hot water through interceptor at a rate of between 1 1/2 and 2 1/2 G.P.M.
  5. After water has run into interceptor at this rate for a short period, the unit will fill. Accumulated liquefied grease will be raised into cone and draw-off piping.
  6. Allow accumulated liquefied grease to flow out of draw-off valve until clear water appears.
  7. When clear water appears, shut off flow of hot water into interceptor, turn line control valve to open position. Close semi-automatic draw-off valve at top of interceptor.
  8. Interceptor at this stage is ready again for normal use.
