Oasis Concepts FSTB-A80 Servicing the Mechanical Floats, Inspect and Replace Circuit Board Fuse

D.SERVICING THE MECHANICAL FLOATS

Resetting the Safety Float

1.Remove cover from cabinet.

2.Press down on the safety float re-set button (see figure 8).

Float arm inspection

1.Remove float cap from top reservoir.

2.Float arms should move up and down freely and should not bind or catch (see figure 9).

E. INSPECT AND REPLACE CIRCUIT BOARD FUSE
1.	Disconnect power cord from electrical outlet.
2.	Remove cover from cabinet.
3.	Locate fuse at the lower right side of the circuit board (see
	figure 8) and inspect the fuse filament for breakage.
4.	If fuse appears to have blown, carefully remove it from the
	circuit board and check it for continuity.
5.	If fuse is blown, replace it with a 25 volt, 5 AMP, slow blow
	fuse.
F. INSPECT AND REPLACE DUMP SOLENOID VALVE
1.	Disconnect power cord from electrical outlet.
2.	Remove cover from cabinet.
3.	Locate dump solenoid (see figure 8) and visually inspect clear
	solenoid valve body for mineral build up or debris.	Loosen Solenoid
		Screws (2)
4.	If build up or obstruction has occurred, remove the hot tank assembly
	from the outer cabinet (see section C).

5.Remove both sets of wires from the solenoid valve.

6.Remove from the solenoid valve both the silicone tube from the hot tank and the angled silicone tube going to the spray head.

7.Remove the dump solenoid by loosening the two screws that hold it to

the bracket assembly. Once the screws have been loosened, the

solenoid valve can be removed from the bracket slots (see figure 10).	Figure 10
	Dump Solenoid Valve
8. If replacement is required, assemble a new or refurbished dump
solenoid valve in the reverse order.

G.THERMOSTAT REPLACEMENT Primary Thermostat (see figure11)

1.Disconnect the power cord from both the electrical outlet and the IEC plug located at the rear of the brewer (see figure 5).

2.Remove the hot tank assembly from the outer cabinet (see section C).

3.Remove both wires from the anti boil thermostat.

4.Loosen tie wire and remove the rear half of the insulation from the hot tank.

5.Using an 11/32 inch nut driver, remove nut from thermostat threaded weld stud. Nut secures thermostat and cover.

6.Remove thermostat cover.

7.Remove thermostat from threaded weld stud.

8.Remove both wires from thermostat.

9.Replace using the reverse order as above.

NOTE: When threading the nut back to the weld stud (the reverse of step 5) a torque value of 18 inch pounds must be applied for proper assembly.

Anti-Boil Thermostat (see figure 11)

1.Follow steps (1-4) from Primary Thermostat.

2.Using a ¼ inch nut driver remove both screws from bracket.

3.Replace using the reverse order.
