Important Safety Instructions

WARNING

To reduce the risk of fire, electric shock, serious injury or death to persons when using your washer, follow these basic precautions:

1. Read all instructions before using the washer-extractor.

2. Refer to the GROUNDING INSTRUCTIONS in the INSTALLATION manual (supplied with your washerextractor) for the proper grounding of the washer-extractor.

3. Do not wash textiles that have been previously cleaned in, washed in, soaked in or spotted with gasoline, drycleaning solvents or other flammable or explosive substances. They give off vapors that could ignite or explode.

4. Do not add gasoline, dry-cleaning solvents or other flammable or explosive substances to the wash water. These substances give off vapors that could ignite or explode.

5. Under certain conditions, hydrogen gas may be produced in a hot water system that has not been used for two weeks or more. HYDROGEN GAS IS EXPLOSIVE. If the hot water system has not been used for such a period, before using a washer-extractor, turn on all hot water faucets and let the water flow from each for several minutes. This will release any accumulated hydrogen gas. The gas is flammable. Do not smoke or use an open flame during this time.

17. EXCESSIVE CYCLE TIME When experiencing excessive cycle time, there are three main causes which are as follows:

a. Fill Time:

(1) Check for excessively long fill times. Refer to the “Fill Alarm Analysis” flowchart if any are found. (2) Check for excessively long programmed fill times.

NOTE: All pre-programmed fill times are for 5 minutes. Any fill should easily complete during this time.

b. Drain Time:

(1) Look for excessively long programmed drain times (i.e., greater than one minute).

NOTE: Any drain step should not exceed 30-40 seconds.

c. Unnecessary Programming Steps:

(1) E.g., in the first fill of a cycle, if “S02 CXX 0:00:45” “SUPPLY1” is programmed for 45 seconds and

“S03 CXX 0:00:45” “SUPPLY2” is programmed for 45 seconds, the two steps can be accomplished together at the same time, saving 45 seconds. Refer to the “Programming Multiple Supply Steps” section of your washer-extractor’s programming manual.

Section 3 Troubleshooting

18. EXCESSIVE VIBRATION AND/OR NOISE DURING SPIN

When experiencing excessive vibration and/or noise during a spin cycle, there are three main causes, which are as follows:

a. Improper Loading:

(1) Always make sure that full loads are used. Never wash partial loads. (2) Do not mix various laundry items together in the same wash (e.g., do not wash towels and sheets

together).

(3) Avoid using laundry bags.

b. Improper Installation:

(1) Make sure that the washer-extractor is anchored to a flat, level surface. (Bolt down on soft mount

products is optional.)

(2) Refer to your washer-extractor’s installation manual for exact installation specifications.

c. Faulty Trunnion Bearings:

(1) Check the trunnion bearings’ noise factor. (2) Lift up on the basket at the front of the tub. Check for any up and down play that would indicate bearing

wear.

(3) Replace the bearings as needed.

DRIVE BELT RE-TENSIONING

Refer to Figure 11. a. Turn off power to the machine.

b. Remove the rear panel. Refer to Paragraph 24. c. Check drive belt tension.

(1) Using a tension gauge, check the drive belt

tension. Belt tension should be between 70 and 90 pounds (± 5 pounds). Set the initial belt tension toward the high end of the range.

(2) To adjust the drive belt tension, loosen or

tighten the nuts on the motor mounting plate bolt. Refer to Figure 10.

d. Check the belt deflection.

(1) Belt deflection measurements should be

taken as close to the center of the belt span as possible.

(2) For every inch of span length, the drive belt

should deflect 1/64 inch (.4 mm). For example, a belt with a span length of 50 inches should deflect 50/64 inch (19.84 mm).

(3) An initial (run-in) force of 5.25 pounds

should be used to set the belt tension. An operating (normal) force of 3.5 pounds should be used after the washer-extractor has been operated for a few hours.

e. Replace the rear panel. Refer to Paragraph 24.
