T-Series Climate Changer Air Handler •

CLCH-SVX06A-EN

Pre-Installation Requirements

Storage Recommendations

A T-Series air handler is an outdoor unit and requires no special protection for storage
before installation. Keep the equipment in the original shipping container for protection
and ease of handling.

Note: The warranty does not cover damage to the unit or controls due to negligence

during storage.

For longer periods of storage, allow enough clearance around the unit to perform
periodic inspection and maintenance of the equipment. In addition, loosen belt tension
on drive belts.

General Storage

The unit controller and all other electronic components should be stored in conditions
of -20ºF to 120

°

F and 5 to 95 percent relative humidity, non-condensing. Electrical

components are not moisture-tolerant.

Long-Term Storage

While the unit is in storage:

•

Every two weeks, rotate the fan and motor shaft 30 revolutions by hand. Check for free
rotation.

•

Every six months, check fan shaft bearings and grease lines. Add grease using a
manual grease gun following the lubrications recommendations in

“Fan Bearing

Lubrication” section on page 90

.

Check the motor lubrication; remove and clean grease plugs and check for the presence
of moisture in the grease. If moisture is present, remove the motor and send it to an
authorized repair shop for bearing inspection/replacement. If no moisture if present,
refer to the motor manufacturer’s lubrication recommendation for proper lubrication.
