Product Description
Refrigerator Temperature Control
General:
WK series temperature controller is a pressure responsed temperature controller. The products are widely used for the commercial refrigerator, refrigerated warehouse, refrigerated cabinet, icecream machines etc.
Installation:
1. The sensing bulb of the temperature controller should be installed at the temperature controlled point with good air ventilaton for correct temperature sense. Please noted that the sensing bulb should be installed on the air return area other than the registered area of the refrigerated warehouse.
2. The capillary tube between the sending bulb and the controller should not pass through the region with lower temperature than the controlled point, and should avoid to contact other pipes.
3. During installation, the bending radius of the capillary tube should not be less than 60mm. And the capillary tube should be clamped with straps every300mm.
4. By turning the button of main adjusting screw and differential adjusting screw(before turning the locating washer should be turned off), the temperature and differential temperature can be set according to the values indicated on the scale.
