MAINTENANCE

DELIMING — GENERAL

WARNING: DELIMING SOLUTION, RINSE AGENTS, OR ANY OTHER KIND OF ACID MUST NOT COME IN CONTACT WITH BLEACH OR RINSE SOLUTION CONTAINING BLEACH USED IN CHEMICAL SANITIZING MACHINES. MIXING MAY CAUSE HAZARDOUS GAS TO FORM. THIS ENTIRE PROCEDURE MUST BE FOLLOWED STEP-BY-STEP FOR SAFE AND SATISFACTORY RESULTS.

Delime the dishwasher on a regular basis as required. The regularity will depend on mineral content of the supply water. Deliming should be done when you can see clear signs of lime deposits (a white chalky substance) on the inside walls and on the wash arms. If you have a model LX40 dishwasher, it is equipped with an automatic delime cycle reminder. It is recommended that deliming be done when DELIME flashes.

Inspect the machine interior for lime deposits. If deliming is necessary, a deliming agent (such as Lime Away or LSR) should be used for best results.

Depending upon the model of your machine, carefully follow the appropriate procedure outlined below.

DELIMING — Models LX18, LX18C & LX18H

1.Remove standpipe assemblies from chemical containers and place them as close to the floor as possible. Place a catch pan under them.

2.Cycle the machine four times to clear the lines of chemicals.

3.Remove rack from machine.

4.Close door.

5.Proceed with step 5 only if your machine is programmed for Modified Fill and Dump. If your machine is programmed for True Fill and Dump, skip step 5 and proceed directly to step 6.

If the displayed temperature is 160°F or below (130°F for LX18C models), start a cycle and wait for the machine to drain and fill. Open the door slowly just after the wash pump starts.

If the displayed temperature is above 160°F (130°F on LX18C), start a cycle. Open the door slowly just after the wash pump starts.

6.Add deliming agent (carefully follow supplier's instructions). The sump holds approximately 3 gallons of water.

7.Close door. Machine will complete the wash/rinse cycle.

8.Inspect interior of machine for lime deposits. Repeat steps 4 through 8 if necessary.

9.Press ON. Run two cycles to purge the system of deliming agent. Press OFF.

10.Put standpipe assemblies back into the appropriate chemical containers (see page 8).

11.Press ON. Run four cycles to prime the chemical delivery pumps.

12.Press OFF.

CAUTION: Do not allow the deliming agent to remain in the machine longer than recommended by the deliming agent manufacturer.
