SB-1 12 Volt Power Supply Change Procedure
Model:
PT-200FT, PT-200RC & PT-56
Software version:
All
Tools Required:
Phillips screwdriver
Process:
1. Turn booster heater power switch off, unplug the unit from the 110v AC wall
outlet and remove front cover.
2. Ensure that the power supply you are replacing is for 12 Volts and not 24
Volts. If you attempt to install the incorrect power supply, it will damage the
unit and void any warranty.
3. Remove the 4 screws holding the power supply bracket and remove the
power supply.
4. On the new power supply find the wire that has the white printing (+). Attach
this lead to the circuit breaker located in the control drawer. The plain black
lead (-) connects to the ground terminal.
5. Place the power supply in the bracket and re-attach.
6. Plug 110v AC into outlet and turn booster heater power.
7. Verify that the green LED is flashing; ensure proper operation by running
several racks through the dish machine.
