contactor operates
(See the schematic on the back of the lower access panel).
1 Phase to 3 Phase Field Conversion
Models UH100B, UH170B, UH200B
Models beginning with S/N 14326 are wired for 1 PH operation. The Phase of the dishwasher may be
changed by changing the element jumpers for 3 Ph operation and connecting the wire marked 1H3 as
shown below. The 1H3 wire is located on the right-side of the booster heater wiring harness next to the
booster heater. To convert the booster heater:
1. Make sure power is turned off.
2. Remove the black booster heater cover.
3. Change the jumpers.
4. Replace the booster heater cover.
5. Request the a qualified electrician connect a 3 PH power supply to the machine.
Note:
1. The Main Terminal Block
(MTB) is a 4-pole connection
block.
2. The main incoming can be
1 PH or 3 PH depending on
the needs of the customer.
3. Instructions for the conversion
of the booster heater element
from 1 PH to 3 PH are located
on the back of the lower
access panel.
4. A new machine data plate is
located on the back of the
panel too.
5.
THE OLD DATA PLATE ON
THE LOWER LEFT CONER
OF THE DISHWASHER
MUST BE REMOVED AND
REPLACED WITH THE NEW
DATA PLATE.
6.
ONLY a qualified electrician
is allowed to change the
incoming power to the
machine.
