DISPOSAL AND STORAGE

STORAGE

If the contactor is to be stored for any length of

time prior to installation, the following

precautions should be taken.

1. The original packing should be restored, if

possible.

2. Do not subject the equipment to moisture or

sunrays. Store in cool, clean, and dry

location.

3. Place a dust cover over the contactor

packaging to protect against dirt and

moisture.

4. Store in an upright position.

INSPECTION DURING STORAGE

Routine scheduled inspection is necessary if

storage is for an extended period. The unit

should be checked for condensation, moisture,

corrosion, and vermin.

Prior to installation, the contactor should be

carefully examined for evidence of physical

damage, corrosion, or other deterioration. Refer

to the PRE-ENERGIZATION Section of this

manual.

The MAINTENANCE section of this manual

describes various types of inspections

recommended for this contactor during the

operation period.

DISPOSAL

Contact your state environmental agency for

details on disposal of electrical components and

packaging in your particular area.
