ratings are correct for the application.

During repairs, be sure all connectors are

tight and wires are properly routed.

•Loose wires could be damaged, causing shock

or fire hazards.

Be sure the power cord is undamaged.

•Do not bend, twist, pull, or damage the cord. It

Product Installation Method

Chapter 3

Chapter 3 Product Installation Method

1. Method to adjust height of storage

■Adjust the level of storage.

(If the floor is uneven, the storage may vibrate or cause noise.)

➲Adjust the front to be level by turning the height adjutsment screws under the front corners.

Tilting the unit backward slightly to take the weight off the adjusting screws may make this

task easier.

2. Grounding method

Plug the cord into a 115 V grounded outlet. If you are unsure of the voltage or grounding integrity,

consult a qualified electrician.

➲ Take care not to ground the circuit at one of the following places:

1. Water pipe: If there is plastic piping within the system, the ground may not be valid.

2. Gas pipe: There is the danger of fire or explosion.

3. Phone line or lightning rod: If lightning strikes, dangerous voltage may be induced

in the circuit.
