CONFIRMING THE SCALE CHECKLIST

Blank Display or No Warnings.

Check wire connections from scale assembly to the circuit board for configuration and

continuity.

Verify that the circuit board is receiving proper voltage (refer to the decal on the back of

the unit) and the two amp or 1/2 amp fuse is not blown. Use properly grounded active

electrical outlets only. Replace the circuit board or fuses as needed.

Total Amounts Not Accurate

Verify that nothing is touching, blocking, or interfering in any way with the scale assem-

bly, tank, or hoses. Confirm that the total weight on the scale assembly is not exceeding

80 lb/37 kg. If it is, reduce the amount of refrigerant in the tank.

Full (Full Tank Setting)

The compressor will shut off at the weight previously set. To check the weight of the

tank, scale, and refrigerant being recovered, follow the appropriate sections found under

USING THE DIAGNOSTIC MODE.

CORRECT WEIGHT VERIFICATION

1. Turn on the MAIN POWER switch.

2. Press SHIFT/RESET until "PROGRAM" displays.

NOTE: If the unit is just being turned on, the screen will default to display the selected

refrigerant type. Press SHIFT/RESET until "PROGRAM" displays.

3. When "PROGRAM" message displays, press and hold SHIFT/RESET, then press

ENTER. The "FUNC" message will display when the manual diagnostic mode has

been accessed properly.

4. Remove all weight from the scale platform.

5. Press 6 to turn the scale into a direct-reading weight scale.

NOTE: Any weight on the scale when 6 is pressed will not be shown on the display.

The unit automatically zeros the weight on the scale when 6 is pressed. If you remove the

weight, the display will show the change in total weight but will not show a negative sign.

6. Place a known weight of between 30-60 lbs./13-28 kg. on the scale. The display

will show the known weight "± .04lb./.02 kg."

7. If the scale does not read the weight accurately, recalibrate the scale and UL circuit

using the following instructions.
