• Failure to install, maintain and/or operate this product according to the manufacturer’s

instructions may result in conditions which can produce serious injury, death and/or property

damage.

• Do not repair or replace any part of the product or attempt any servicing unless specifically

recommended or published in this Service Manual and unless you understand and have the

skills to carry out the servicing.

• Whenever ground wires are removed during servicing, these ground wires must be

reconnected to ensure that the product is properly grounded and to reduce the risk of fire,

electric shock, serious injury or death.

W006R2

WARNING

(continued)

49001900

Section 1 Safety Information

Always contact your dealer, distributor, service agent or the manufacturer about any problems or conditions you do

not understand.

Important Safety Instructions

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

2. Refer to the GROUNDING INSTRUCTIONS in the INSTALLATION manual (supplied with your washer-

extractor) 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, dry-

cleaning 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.

To reduce the risk of electric shock, fire, explosion, serious injury or death:

• Disconnect electric power to the washer-extractor before servicing.

• Never start the washer-extractor with any guards/panels removed.

• Whenever ground wires are removed during servicing, these ground wires must be

reconnected to ensure that the washer-extractor is properly grounded.

compartment.

8. Do not reach into the washer-extractor if the wash basket is moving.

9. Do not install or store the washer-extractor where it will be exposed to water and/or weather.

10. Do not tamper with the washer-extractor’s controls.

11. Do not repair or replace any part of the washer-extractor or attempt any servicing unless specifically

recommended in the user-maintenance instructions or in published user-repair instructions that the user

understands and has the skills to carry out.

12. To reduce the risk of an electrical shock or fire, DO NOT use an extension cord or an adapter to connect the

washer-extractor to an electrical power source.

13. Use the washer-extractor only for its intended purpose, washing clothes.

14. ALWAYS disconnect the washer-extractor from its electrical supply before attempting any service.

15. Install the washer-extractor according to the INSTALLATION INSTRUCTIONS. All connections for water,

drain, electrical power and grounding must comply with local codes and, when required, be made by licensed

personnel.

16. To reduce the risk of fire, textiles which have traces of any flammable substances such as vegetable oil,

cooking oil, machine oil, flammable chemicals, thinner, etc. or anything containing wax or chemicals such as

in mops or cleaning cloths, must not be put into the washer-extractor. These flammable substances may cause

the fabric to ignite.

17. Do not use fabric softeners or products to eliminate static unless recommended by the manufacturer of the

fabric softener or product.

18. Keep the washer-extractor in good condition. Bumping or dropping the washer-extractor can damage its safety

features. If this occurs, have the washer-extractor checked by a qualified service person.

19. Replace worn power cords and/or loose plugs.

20. Be sure that water connections have a shut-off valve and that fill hose connections are tight. CLOSE the shut-

off valves at the end of each wash day.

21. The loading door MUST BE CLOSED any time the washer-extractor is to fill, tumble or spin. DO NOT by-

pass the loading door switch and permit the washer-extractor to operate with the loading door open.

22. Always read and follow the manufacturer’s instructions on packages of laundry and cleaning aids. Heed all

warnings and precautions. To reduce the risk of poisoning or chemical burns, keep them out of the reach of

children at all times (preferably in a locked cabinet).

23. Always follow the fabric care instructions supplied by the textile manufacturer.

24. Never operate the washer-extractor with any guards and/or panels removed.

25. DO NOT operate the washer-extractor with missing or broken parts.

26. DO NOT by-pass any safety devices.

27. Failure to install, maintain and/or operate this washer-extractor according to the manufacturer's instructions

(overcurrent) During acceleration—If a current of more than

150% of the rated inverter current flows in the motor,

this function stops the increase in frequency until the

overload current reduces to prevent the inverter from

resulting in overcurrent shut-off. When the overload

current has reduced below 150%, this function

increases the frequency again.

During constant-speed operation—If a current of

more than 150% of the rated inverter current flows in

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.
