N N o o t t e e : : The drive belt is a urethane stretch belt

designed to provide constant tension

throughout the life of the belt. No periodic

adjustment is required. Inspect the belt

annually for proper tracking and tension. A

properly tensioned belt will turn the wheel

immediately, with no visible slippage, when

power is applied.

4. If the wheel has difficulty starting, turn off the

power and inspect the wheel for excessive

interference between the wheel surface and the

four diameter seals. To correct interference, loosen

the diameter seal adjusting screws and back the

diameter seals away from the surface of the wheel.

Apply power to confirm free wheel rotation. Re-

adjust and tighten the seals according to

instructions in the "Service and Repair" section.

Damper Actuators

Stroke the actuators to observe full open and full

closure of the dampers.

Cleaning the Energy Wheel

Disconnect all electrical power, then use a vacuum or

brush to remove accumulated material from the face of

the wheel. Examine the energy wheel monthly for

material build-up on the wheel. If more aggressive

cleaning is needed, removed the wheel segments and

follow these steps:

1. Wash the segments or the wheel in a five-percent

solution of non-acid-base coil cleaner (part no.

CHM00021 at your local Trane parts center) or in an

alkaline detergent and warm water.

2. Soak the segments in the solution until grease, oil,

and tar deposits are loosened.

3. Before removing the cleaner, rapidly run your

fingers across the surface of segments to separate

polymer strips for better cleaning action.

4. Rinse the dirty solution from the segments and

remove the excess water before re-installing the

segments in the wheel.

N N o o t t e e : : Some permanent staining of the desiccant

may remain but is not harmful to

performance.

Cleaning Frequency

In reasonably clean office or school buildings, cleaning

with a coil cleaner solution may not be required for

several years. If the energy wheel is exposed to air

streams containing, for example, high levels of

occupant tobacco smoke, cooking facility exhaust air,

or oil-based aerosols found in machine shop areas,

annual or more frequent cleaning may be required to

remove these contaminants and restore performance.

Periodic inspection of the wheel should be done to

determine the cleaning intervals.

High-maintenance applications may benefit from

keeping a spare set of clean segments on hand. This

allows for rapid change-out of clean segments with

minimal downtime. The dirty segments can then be

cleaned at a convenient time.
