4. INSTALLATION

INSTALLATION

The appliance should be installed as follows.

Check the conditions of installation area.

1. Check level ground.

On raised foundations or upper level homes, the vibrations can be caused by the type of flooring.

It may be necessary to move the machine to a different area in the home or have the floor

reinforced to properly support the operation of the unit.

2. Check for humidity or any foreign objects under the feet.

Clean the floor, there should be no foreign objects under the feet.

If the unit has foreign objects underneath the feet, this will prevent the unit from being leveled properly

and will cause vibrations and slipping.

Remove any foreign objects, if any from underneath the machine and level unit properly.

See below for examples of foreign objects.

Open the box and check appliance condition.

1. 2. 3.

Connect Drain Hose.

Connect power plug.

If the drain hose is not installed properly, the unit will not drain properly.

This allows water to back flow into the unit which can cause odors.

Refer to Owner Manual for proper drain hose installation.

The odor could also be coming from the home’s drain to which the drain hose is attached.

In this type of drain hose installation, the odor could be coming from the standpipe.

This odor can come up the drain hose and into the unit.

Pour a cup or two of bleach or vinegar down the home drain

and let it sit for 24 hours before running another cycle.

This will help eliminate odor from the home drain.

If a cycle is started too soon after doing this, it will not help the issue.

Connect the power plug to the wall outlet. Avoid connecting several electric devices,

it may be the cause of a fire.

If the unit is vibrating, make small adjustments to the leg until they subside. (Repeat step 2)

Step 4

Tighten the lock nut against the base of the machine to lock the position leg.

Lower the foot until there is no gap between floor and foot.

And only use adjustment rubber when difference at the leg adjustment is more than 10mm.
