5. ഓപ്പറേഷൻ
The Master-Bilt 19-00816 Timer Unit utilizes a mechanical dial for setting operational cycles, typically for defrost or other timed functions within a refrigeration system.
- ദിവസത്തിന്റെ സമയം ക്രമീകരിക്കുക: Rotate the outer dial of the timer until the current time aligns with the indicator arrow or mark on the timer's stationary housing.
- Setting ON/OFF Cycles: The timer dial features small pins or segments around its circumference.
- To set an "ON" period, push the corresponding pins/segments inwards.
- To set an "OFF" period, leave the corresponding pins/segments outwards.
- Each segment typically represents a specific time interval (e.g., 15 minutes). Consult the timer's markings for precise intervals.
- മാനുവൽ ഓവർറൈഡ് (ബാധകമെങ്കിൽ): Some timers may include a manual override switch or lever. Refer to the timer unit itself for any such feature and its operation.
