CHECKING AND CLEANING THE WATER STRAINER
The Water Strainer protects the unit from any foreign
debris in the water line that could get into the food,
damage the unit’s solenoid (causing the unit to leak or
flood), or interfere with the equipment’s proper and con-
sistent operation (Figure 10).
To ensure proper and consistent steaming results,
check the Water Pressure Regulator and Strainer
Cup regularly. If the pressure on the Water Pressure
Regulator has dropped, check the clear plastic Strainer
Cup and clean out the accumulated debris.
1. Shut off the water supply valve to the unit,
unscrew the plastic Strainer Cup, and carefully
remove the mesh Strainer Screen.
2. Take the Strainer Cup and Strainer Screen to
the sink and gently flush out all the accumulated
debris. Be especially careful not to damage the
Strainer Screen.
3. Carefully place the Strainer Screen into its seat at
the bottom of the Strainer Cup and confirm that
the orange O-ring is properly seated in its place
before screwing the Strainer Cup and top back
together.
4. Purge the air out of the strainer and tubing by dis-
connecting the male quick disconnect fitting from
the equipment and, over a bucket, pushing the
white plastic tip in until there is a good water flow.
5. Replace damaged or worn parts as needed.
