Hobart FT900SDBD, FT900SBD, FT900DBD, FT900BD manual Tank Filling

TANK FILLING

Assure proper water hardness. Recommended water hardness is 3 grains or less per gallon. Higher hardness may cause excessive formation of lime scale. Chlorides must not exceed 50 ppm.

All water (and steam, if equipped) supply valves must be opened and the electric supply turned on before the machine will function.

Close all drains and doors. The drain handles are located near the floor at the front of each tank. Rotate drain handles clockwise to the vertical position. The prewash tank, powerwash tank and power rinse tank (when equipped) and their respective drain handles are located towards the load end of the machine from the control box. The drain handle for the dual rinse tank (when equipped) is located towards the unload end of the machine from the control box.

Press the Power key on the keypad located on the lid of the control box (Fig. 8). The display will light up.

If door(s) are not closed Door(s) Open displays. If all doors are closed, Tanks Filling ... displays and tanks begin to fill. All tanks will be full in approximately 10 to 15 minutes. NOTE: Opening a door during the fill cycle shuts off the fill valves (Door(s) Open displays). Close the door to resume the fill cycle (Tanks Filling ... displays).

When all tanks are full the fill valves will automatically shut off and the water temperatures display for each tank. The full time Auto-Fill feature adds water to the tanks to maintain proper water levels during operation.

After the water level raises the lower float in each tank, the wash, rinse and dual rinse tanks, if equipped, begin to heat. If the water level drops below the lower float in any tank, the heat shuts off and filling resumes on the affected tank(s). When the water level reaches the lower float, heating resumes while the tank(s) continue(s) filling until the proper water level is reached. If the water level drops below the lower float in the prewash tank, filling resumes until the water level reaches the upper float.
