PATENT PENDING

When using electrical equipment, basic safety precautions should always be followed
including the following:

READ AND FOLLOW ALL SAFETY INSTRUCTIONS

1. Do not use outdoors.

2. Do not mount near gas or electric heaters.

3. Equipment should be mounted in locations and heights where it will not readily

be subjected to tampering by unauthorized personnel.

4. The use of accessory equipment not recommended by the manufacturer may

cause an unsafe condition.

5. Do not use this equipment for other than intended use.

6. Refer service to qualified personnel.

SAVE THESE INSTRUCTIONS

WARNING: 

You must have access to a main circuit breaker or other power

disconnect device before installing any wiring. Installing the device with power on
may expose you to dangerous voltage and damage the device. A qualified
electrician must perform this installation.

WARNING: 

If replacing the fuse in this unit, you must replace fuse with exact

same type and rating.

WARNING: 

Refer to National Electrical Code® and local codes for cable

specifications. Failure to use proper cable can result in damage to equipment or
danger to persons.

WARNING: 

This equipment is intended for installation in accordance with the

National Electric Code® and local regulations. It is also intended for permanent
installation in indoor applications only. Before any electrical work is performed,
disconnect power at the circuit breaker or remove the fuse to avoid shock or
damage to the control. It is recommended that a qualified electrician perform this
installation.

CAUTION: 

Wire openings must have fittings or lining to protect wires/cables

from damage. Use 90° C copper wire only.
